1# g1t plan
2
3g1t is where people and agents ship software together: a git platform built on Cloudflare Workers and Artifacts for
4the "Build the Next-Gen Git Platform on Cloudflare" competition.
5
6- Submission closes **October 14, 2026, 11:59 PM PDT**: a 5–10 minute demo
7 video, this repository (MIT) and run instructions.
8- Judging: 50% originality and quality of the prototype for agent-oriented
9 collaboration; 25% multi-agent concurrency, coordination, context
10 preservation, review and conflict handling; 25% ease of use.
11
12## The point
13
14**g1t is where a team of agents ships code, with the people they work for.**
15
16Hosting git is table stakes, and g1t does it the familiar way: issues,
17branches, pull requests, review, protected branches, people working by hand.
18None of that is the selling point. The selling point is the layer above it,
19which no forge has: **you hand g1t an outcome, and a fleet of agents converges
20it onto `main`, coordinating with each other and with you, with every decision
21on the record.**
22
23Three things only g1t does, and every feature should serve one of them:
24
251. **Outcomes, not pull requests.** The unit people work in is "make onboarding
26 work offline", not branch #4012. A brief becomes a plan of issues with
27 dependencies; agents take them as they unblock; people steer the outcome
28 and see it converge, rather than stopping at the pull request.
292. **Agents that work as a team.** Agents know what the others are doing, file
30 what they find instead of widening their change, ask and answer each other
31 through the forge, and defer to people. Many agents on one codebase without
32 a human refereeing collisions.
333. **`main` that only ever moves forward.** Every change lands through checks
34 in the combination it will live in (the merge queue), failures go back to the
35 agent that wrote them, and any line can answer "why is this here?"
36
37## Product model
38
39g1t keeps the two things every engineer already knows, issues and pull
40requests, and changes the assumption underneath them. A forge built for
41people expects a few changes in flight, each watched by its author. g1t
42expects dozens of agents working at once across a project, each on its own
43issue, all of which have to land on `main`. A person assigns an issue to
44g1t and chooses nothing else: not how many agents, and not which
45model. An issue can still collect more than one pull request (a second
46attempt, or someone's own agent alongside g1t's), and when it does the
47issue records which one was taken.
48
49| Concept | What it is |
50| --- | --- |
51| **Issue** | What should change in a repo: a bug, a feature, a question. Opened by a person, an agent or an integration such as an error tracker. Carries labels, a description that may say what done means (a Definition of done: context, never a gate), comments, and every pull request made for it. What a merge needs is the default branch's required checks: workflow statuses, the same for people and agents. |
52| **Pull request** | A proposed change in its own Artifacts fork, made by an agent or a person, usually for an issue. Any number can be open for one issue. Starts as a draft; marked ready; merged or closed. |
53| **Session** | The agent's full context for a pull request: prompt, messages, tool calls, cost. Stored with the pull request and linked from every commit it produced. |
54| **Compare view** | Every pull request for an issue side by side with diff, check results, conflicts against main and against each other, and a reviewer agent's summary. |
55| **Merge** | A person or a policy picks a pull request. A per-repo merge queue lands it. The issue closes, recording which pull request resolved it; the others for that issue close as superseded, or are rebased by their agents when the issue is kept open. |
56
57Issues and pull requests share one sequence of numbers per repository, so
58`#12` names exactly one of them.
59
60Features that fall out of the model:
61
62- **Why-blame.** Click a line and see the prompt and reasoning that produced
63 it, not only the commit.
64- **Overlap radar.** Pull requests that touch the same files are flagged
65 while the agents are still working, and the agents are told.
66- **Live lanes.** Watch every pull request progress in real time.
67
68## Why issues and pull requests, not something new
69
70An earlier version of this plan merged the two into one new object, an
71"issue" holding "pull requests". That was wrong, for three reasons.
72
73- **Issues come from everywhere.** People file them, agents file them, and
74 Sentry files them. Most are never worked on by whoever opened them. They
75 need their own life: labels, triage, discussion, closing as not planned.
76- **"Which change did we take?" needs two objects.** When five agents each
77 propose a change, the answer has to be recorded somewhere other than the
78 five proposals. On g1t it is on the issue: `resolved by #14`.
79- **Nobody should have to learn a word to use the product.** An engineer who
80 has used any forge can use g1t on the first day, and finds the agent
81 features where they would look for them.
82
83What g1t adds to the familiar pair:
84
85- **Several pull requests per issue is supported**, not an accident. It
86 is the exception, for a second attempt or a competing one, but when it
87 happens the issue's page lists them with their state, and merging one
88 closes the issue with that pull request recorded and the others marked
89 superseded.
90- **A pull request can be part of the work.** Merging with "keep the issue
91 open" leaves the issue and its other pull requests alone.
92- **Every pull request has a fork and a session.** See
93 [forks and branches](https://docs.g1t.sh/concepts/forks/).
94- **Labels need no setup.** A repository starts with the default labels
95 (`bug`, `documentation`, `enhancement`, `question`, `dependencies`,
96 `security` and the rest), each with a color and a description, on issues
97 and pull requests alike; someone with Triage makes a new one as they use
98 it. **Milestones** gather issues and pull requests under a goal and a
99 due date. Pull requests can merge into any branch; the default branch's
100 protection holds only for those into it.
101- **The developer path is unchanged.** Push a branch, open a pull request
102 from it, get review, merge. Agents get a fork per pull request instead.
103- **Both paths meet at `main`.** The same landing rules apply to a person's
104 pull request and an agent's.
105
106## Converging on main
107
108Twelve issues started together will finish at different times and touch
109overlapping code. Getting them all into `main` without a person refereeing
110is the hard part, and it is handled in four places.
111
1121. **Before work starts: plan the overlap away.** A project is a graph of
113 issues. A planner agent can split a large goal into issues, predict
114 which files each will touch, and add a dependency where two would collide,
115 so one starts from the other's result instead of from `main`.
1162. **While agents work: overlap radar.** Each pull request's changed files and
117 symbols are tracked as it pushes. When two pull requests from different issues
118 enter the same area, both agents are told what the other is doing there.
1193. **When `main` moves: the author resolves.** Every open pull request is
120 trial-merged against the new `main`. A clean merge updates the pull request
121 silently. A conflict resumes that pull request's agent with its original
122 session and the incoming change, so the conflict is resolved by the agent
123 that wrote the code and still knows why.
1244. **At landing: a speculative queue.** Approved pull requests enter the
125 repo's queue. g1t builds the combined states (`main`+A, `main`+A+B, …) and runs
126 their checks in parallel. Pull requests land in order as their combined state
127 passes; one that fails is ejected back to its agent and the states behind
128 it are rebuilt. `main` only ever receives a state that passed.
129
130Landing can be fully automatic: a repo policy such as "checks pass and the
131reviewer agent approves" merges without a person.
132
133## Agents aware of each other
134
135Each repo keeps a live **work registry**: for every running pull request, its
136issue, a running summary of what it has done, and the files and symbols it
137has touched or plans to touch. Agents use it through MCP tools; g1t also
138acts on it without being asked.
139
140- **Before starting.** When an issue is opened, or an agent is about to
141 begin a task, g1t searches open issues and running pull requests for the same
142 goal (by meaning, not wording) and for the same area of code. If a match
143 exists the agent is told who is on it and how far along, and chooses: join
144 as a deliberate racer, wait for the result, or drop the task. Duplicate
145 issues are offered for merging.
146- **Finding out-of-scope work.** An agent that discovers something outside
147 its issue asks the registry who works there. If another pull request owns that
148 area, it **hands off**: a note, the relevant excerpt of its session, and
149 optionally commits the receiver can take. If nobody does, it opens a child
150 issue instead of widening its own change.
151- **Asking.** An agent can put a question or a request to another pull request.
152 The receiver gets it at its next turn.
153- **Waiting.** An agent that needs another pull request's result parks itself.
154 Its sandbox sleeps, spend stops, and it resumes from the new state when
155 that pull request merges.
156- **Agents that do not cooperate.** For pushes from tools that never call
157 these tools, g1t compares the pushed change against running pull requests and
158 flags near-duplicates itself.
159
160Every handoff, question and wait has a state (offered, accepted, declined,
161done), appears in the timeline, and is visible to people. A handoff declined
162twice, or two agents passing work back and forth, goes to the "needs you"
163inbox.
164
165## Review at scale
166
167Cloudflare's brief asks "how do you review everything they produce?". With
168hundreds of agents, a person cannot read every diff, so review is by
169exception.
170
171- **Evidence, not diffs.** Every pull request carries a proof bundle: checks run
172 and their output, a preview URL, a plain-language summary, and the
173 behaviour that changed.
174- **Two agent reviewers.** One reviews the change against the issue. A
175 second is adversarial: it tries to break the change and reports what it
176 found.
177- **Risk tiers.** Each change is scored from what it touches, how large it
178 is, and how the reviewers ruled. Low risk merges on policy; high risk goes
179 to a person with the evidence already assembled.
180- **Trust is earned.** An agent's record on a path (merged, reverted, caught
181 by review) raises or lowers the tier its changes land in.
182- **Sampling.** A share of auto-merged changes is sent to a person anyway,
183 to keep the policy honest.
184
185## Rethinking the git primitives
186
187- **No branches for agents.** A pull request is a fork; `main` is the only
188 long-lived line. There is nothing to name, clean up or go stale.
189- **Projected main.** New pull requests start from `main` plus everything already
190 in the landing queue, so they are built on the state they will land on.
191- **Structural merge.** The merge engine merges by syntax tree, not by line,
192 for supported languages. Two agents adding different functions to the same
193 file do not conflict.
194- **Forkable sessions.** A session can be forked at any turn: the code as it
195 was at that moment plus the conversation up to it, continued with a
196 different instruction. Branching applies to the reasoning as well as the
197 code.
198- **Provenance in history.** Every commit records its issue, session,
199 agent, model and cost, and is signed with a key issued to that pull request. The
200 history can be audited by machine.
201
202## People in the loop
203
204### Code that arrives from outside
205
206People will keep pushing with plain git, their editor, or another tool. Every
207push goes through g1t's git front end, so none of it bypasses the model.
208
209- **A push to a branch becomes a pull request.** g1t adopts it with the pusher as
210 author. A reviewer agent writes the issue it appears to serve and offers
211 to attach it to an open issue it matches. From there it gets the same
212 checks, compare view and queue as agent work.
213- **A push to `main` follows repo policy.** Protected: refused with a message
214 saying which ref to push to instead, so it enters the queue. Open: accepted
215 and treated as "`main` moved", which re-verifies the queue and triggers
216 resolve-on-move for every open pull request.
217- **Context is an open format.** A commit trailer names the session that
218 produced it, so any tool can attach its transcript. Commits without one are
219 shown in why-blame as "pushed by a person, no session".
220- **Approval rules.** Per repo and per path: merge automatically, require a
221 named person, or require a person when the change is large or the reviewer
222 agent is unsure.
223
224### Joining work that is already running
225
226- **Every session has a live page** that works on a phone: the transcript as
227 it streams, the current diff, check results.
228- **Steer.** Send a message, pause, or redirect. Hosted agents receive it
229 immediately; a person's own Claude Code receives it at its next turn
230 through the CLI hooks.
231- **Answer.** When an agent is blocked on a question, it appears in a "needs
232 you" inbox and as a notification. The answer resumes the agent.
233- **Take over and hand back.** Check out the pull request's fork, commit by hand,
234 push, and let the agent continue from there.
235
236### Planning by writing
237
238- **Brief.** Write the outcome in prose on the site, or commit it as a
239 markdown file. A planner agent turns it into a project: issues, each with
240 what done means, and dependencies. The person edits the graph before anything starts.
241- **Plan from their own agent.** The same operations are MCP tools, so a
242 person can plan in their own Claude Code session and create the project
243 from there.
244- **The brief stays the source of truth.** Editing it later re-plans: new
245 issues are added, obsolete ones are closed.
246
247### Seeing what moved
248
249- **Project page.** The outcome, the issue graph coloured by state, and how
250 many of its issues have landed with their required checks passing,
251 compared with when the project started.
252- **Digest.** An agent-written summary per project and per person: what
253 merged, what is blocked on whom, which conflicts were resolved, what it
254 cost.
255- **Timeline.** Every event (push, steer, check, conflict, merge) in order,
256 each linked to the session and the person or agent behind it.
257
258## One session, any surface
259
260A session belongs to g1t, not to the device it started on. The browser, a
261phone and Claude Code are views of the same session.
262
263- **Browser and phone.** The site is a responsive, installable web app with
264 push notifications. Everything a person does (brief, steer, answer,
265 approve, merge) works there.
266- **Claude Code.** Through `mcp.g1t.sh` and the CLI hooks, a local session is
267 a g1t session: its transcript syncs as it runs and it appears in mission
268 control like any other.
269- **Moving a session.** A local session can be sent to the cloud: a hosted
270 agent takes over the fork and the transcript and continues, so the laptop
271 can close. A hosted session can be pulled down: the CLI checks out the fork
272 and resumes it in local Claude Code with its history.
273- **Limit.** A session running only on a laptop stops when the laptop does.
274 It can be steered between turns but not continued until it is moved or the
275 laptop is back.
276
277## For people who do not write code
278
279- **Documents are first-class.** Specs, guides, policies and decisions live
280 in Docs, its own mode (docs/WORKSPACE.md, "Docs"), not a tab on a
281 project: rendered pages, edited in the browser like a document, with
282 inline comments, and filtered by the project they are about. "Suggest a change" is an
283 pull request and "publish" is merge, without git vocabulary.
284- **Document issues.** "Write the onboarding guide for the billing API" is
285 an issue. Its Definition of done is a checklist judged by a reviewer agent
286 instead of a workflow. Agents draft and revise; people comment and approve.
287- **Templates.** Product brief, RFC, decision record. A filled-in template is
288 a brief the planner can turn into a project.
289- **Explain.** Ask about any repo, project or change in plain language and
290 get an answer with links to the code and sessions behind it.
291- **Living documentation.** g1t generates "how this works" pages from the
292 code and keeps them current. When a merged change contradicts a document,
293 an issue opens to update it.
294- **See it, don't read it.** Every pull request on a deployable repo gets a
295 preview URL (Workers Builds from the pull request's fork), so an approver clicks
296 through the result instead of reading a diff. Changes are also summarised
297 in plain language.
298- **Roles.** A person can plan and approve work without ever cloning a
299 repo. The roles that were sketched here map onto the five repository
300 roles that are built (see "Access" under what is built): a viewer is
301 Read, a commenter is Read (anyone with Read opens issues and comments),
302 a planner is Triage (labels, milestones, assigning, closing) or Write
303 where planning spends compute, and an approver is Write (reviews count
304 and merges). Workspace-wide, a member may also be a billing manager or a
305 security manager.
306
307## The macro view
308
309The hierarchy above a single repo:
310
311| Level | What it is |
312| --- | --- |
313| **Workspace** | A company or team: its people, repos, agents, budget and policies. |
314| **Initiative** | A business outcome with an owner and measurable results, e.g. "move billing to usage-based pricing". Spans any number of repos. |
315| **Outcome** | One deliverable inside an initiative: a brief and its graph of issues (shown as **Plan**). Called "project" before 2026-10-04; that name now means what [Projects](#projects) describes. |
316| **Issue / Pull request** | As above. An issue may touch several repos; a pull request for it then holds one fork per repo and they land together. |
317
318How it feeds up, and what is built:
319
320- **A workspace is the unit everything belongs to.** Repositories, people,
321 access tokens, and later projects, budgets and policies are the
322 workspace's, never a person's. An account owns nothing; its first step
323 after confirming its email is creating a workspace, and the site sends it
324 there from wherever it was going.
325- **One namespace.** Usernames and workspaces share one set of names, as on
326 Docker Hub and npm. A username is reserved for its owner's workspace, so
327 `g1t.sh/<name>` never means two things.
328- **The workspace page is the roll-up.** `g1t.sh/<workspace>` shows its
329 repositories with their open issues and pull requests, and the pull
330 requests in progress across all of them. Projects and initiatives will
331 roll up to the same page. Its own pages live under `/<workspace>/-/`
332 (people, access tokens, settings), which no repository can be named.
333- **Workspace access tokens instead of service accounts.** A workspace has
334 tokens of its own, in the same table and code path as personal ones. One
335 acts as the workspace, with a member's rights in that workspace only (the
336 Write role on its repositories; Admin only when an owner ticks it at
337 creation, `access_tokens.admin`, identity/0034), records who made it and
338 when it was last used, and keeps working when that person leaves. CI,
339 integrations and automations use these. Until 2026-10-08 the code gave
340 them Admin on every repository, which the security audit found let any
341 workspace token manage webhooks; code, this plan and the docs now agree.
342
343### Portfolio
344
345One page answers "where is the business" across every initiative:
346
347- **Health** per initiative: on track, at risk, or blocked, derived from
348 facts (checks passing, issues stalled, questions waiting on a person),
349 not self-reported.
350- **Progress** as measurable results: required checks passing, issues
351 merged out of planned, and the trend since the start.
352- **Forecast** from actual throughput: at the current rate, when the
353 remaining issues land.
354- **Spend** in tokens and dollars against a budget, per initiative.
355- **Waiting on people**: every decision or approval a person owes, by name.
356- **Roadmap**: initiatives laid out as now, next, later, with optional
357 time-boxed cycles for teams that work in sprints.
358
359### Status without asking
360
361- **Standup.** An agent writes a daily report per initiative and one for the
362 whole workspace: what merged, what changed direction, what is at risk and
363 why, what needs a person. Delivered by email or webhook.
364- **Ask.** A question box over the full event log and all sessions: "what
365 happened on the billing migration since Monday?" answers with links to the
366 sessions and commits behind each claim.
367
368### Long-running agents
369
370Work that runs for days needs supervision that does not depend on someone
371watching.
372
373- **Checkpoints.** A long pull request reports milestones against its issue, so
374 progress is visible before anything merges.
375- **Stall and drift detection.** A pull request with no meaningful progress, or
376 whose changes have wandered away from its issue, is flagged and can be
377 stopped or re-briefed automatically.
378- **Budgets.** Hard limits on spend and time per pull request, project and
379 initiative.
380
381### Context hub
382
383Agents working across repos and days need context that outlives any one
384session and reaches beyond the code. The context hub is one place an agent
385asks, whatever the source.
386
387| Source | What it holds | How it gets there |
388| --- | --- | --- |
389| **Memory** | Decisions, conventions, gotchas, facts about systems | Written by agents and people in g1t |
390| **Code and sessions** | The repos, and the reasoning behind every change | Already in g1t |
391| **Connected sources** | Jira and Linear tickets, Notion and Confluence pages, Google Drive documents, Slack threads, Sentry issues | Connectors, authorised per workspace |
392
393How it behaves:
394
395- **One search.** An agent asks a question and gets ranked results across
396 all sources, each labelled with where it came from, who wrote it, and how
397 fresh it is.
398- **Connected sources stay where they are.** g1t indexes them for search and
399 fetches the current version when an agent opens one. The external system
400 remains the source of truth, and a link placed on an issue ("see
401 JIRA-482", a Notion URL) is pulled into the agent's starting context.
402- **Permissions carry over.** A connector only exposes what the connecting
403 account can see, and a workspace admin chooses which spaces, projects or
404 channels are included.
405- **External content is untrusted.** A ticket or page can contain text meant
406 to manipulate an agent. It is marked as reference material, never treated
407 as instructions.
408- **Documentation is separate.** Context is what agents know; documentation
409 is what people read, and it is generated from context and code.
410
411Memory is the part of the hub that g1t owns and agents write to:
412
413- **Memory is written freely.** Any agent or person adds an entry with one
414 call: a decision, a convention, a gotcha, a fact about a system. No review
415 gate. Each entry records who wrote it, from which session, and when.
416- **It is still a repository.** Each workspace has a memory repo in
417 Artifacts, so every write is a commit: versioned, attributable, and
418 revertible.
419- **It is kept healthy by an agent.** A consolidation agent merges
420 duplicates, retires entries that newer ones contradict, and flags
421 conflicts it cannot settle. People can pin an entry (agents may not change
422 it), correct it, or retract it.
423- **Agents read it.** Every session starts with the context relevant to its
424 issue, found by search, and can query more through MCP.
425- **Updates are events.** A memory write or a change in a connected source
426 is an event, so "when context changes, update the affected docs" is an
427 automation, on by default.
428- **It is scoped inside the workspace.** Some context applies to the whole
429 workspace, some to one initiative, project or repo, so an agent gets what
430 applies to its work.
431- **It never crosses workspaces.** A workspace is the isolation boundary: its
432 context, sessions and private repos are invisible to every other
433 workspace, and an agent's token is bound to one workspace.
434
435## Working in g1t
436
437- **Mission control.** The signed-in home page: every running session, every
438 issue waiting on a decision, and what merged, across all repos.
439- **Outcomes.** Group issues across repos toward one result and track how
440 many are open, racing, or merged. (What [Projects](#projects) means is
441 below.)
442- **Steering.** Send a message to a running pull request, or to all pull requests on an
443 issue at once, without stopping them.
444- **Automations.** Rules that start work without a person (next section).
445
446## Automations and integrations
447
448> **2026-10-03:** g1t's own `.g1t/automations` format was built and then set
449> aside at the user's request ("let's just copy GitHub Actions on that for the
450> time being"). Automation on g1t is GitHub Actions workflows in
451> `.g1t/workflows/`; the format below is kept for later.
452
453An automation is **when** an event happens, **if** conditions hold, **do**
454something. They are defined as files in the repo (`.g1t/automations/`), the
455way GitHub Actions workflows are, and can also be built in the UI.
456
457### Events that can trigger one
458
459| Source | Examples |
460| --- | --- |
461| Git | push, merge, check failed, `main` moved |
462| g1t | issue opened, pull request stalled, context updated, handoff declined, budget reached |
463| Time | cron schedule |
464| Integrations | Sentry issue, PagerDuty incident, Linear or Jira ticket, Slack message or mention, GitHub issue, Stripe event |
465| Anything else | a signed generic webhook, or an email to a per-repo address |
466
467**Actions**: open an issue (optionally assigning N agents to it), message
468a running pull request, update documentation, notify, call a
469webhook, write back to the source system.
470
471**Example: Sentry.** A new production error arrives. The automation opens an
472issue labelled `bug`, with the stack trace, release and frequency in its
473description. Why-blame
474finds the session that wrote the failing line, so the fixing agent starts
475with the original reasoning. When the fix merges, g1t comments on the Sentry
476issue and resolves it.
477
478### Rules every automation obeys
479
480- **Deduplication.** The same Sentry issue firing 500 times maps to one
481 issue.
482- **Limits.** Concurrency and budget caps per automation.
483- **Loop protection.** Work started by an automation cannot retrigger the
484 same automation without a person in between.
485- **External input is untrusted.** A webhook payload can contain text written
486 by an attacker. Agents started by external events run with reduced
487 permissions and cannot merge without the repo's approval rule passing.
488
489**Checks** are the other half of what GitHub Actions does: build and test
490commands declared in `.g1t/checks.yaml`, run in sandboxes on every pull request
491and on every combined state in the landing queue.
492
493### Tokens, scopes and packages the GitHub way (built 2026-10-08)
494
495> **2026-10-08 (owner):** "emulate all of what GitHub does for scope
496> mapping and packages." GitHub's current behaviour is the spec.
497
498This **reverses identity/0023**, which retired a token's reach to some
499workspaces or repositories and left classic tokens only. The reason it is
500reversed: the owner chose GitHub parity, and GitHub has fine-grained tokens
501beside classic ones, with workspaces (organizations) governing both.
502
503- **Fine-grained personal access tokens** (identity/0034,
504 `services/identity/src/token_reach.rs`, `g1t_contracts::fine_grained`):
505 one resource owner (a workspace the person belongs to, or their own
506 account), all, selected (up to 50, by repository id) or only public
507 repositories, and a level per permission under GitHub's names (contents,
508 metadata, issues, pull_requests, actions, workflows, checks, statuses,
509 deployments, pages, environments, secrets, variables, webhooks,
510 administration, packages, security_events; members,
511 workspace_administration, self_hosted_runners, workspace_secrets,
512 workspace_webhooks, workspace_billing, models; email_addresses, starring,
513 notifications; g1t's agents and memory). Each level maps onto g1t's
514 scopes, which the token stores, so every check that reads scopes
515 (`scopes::decide` for the API and MCP, `decide_git`, `decide_packages`)
516 reads them unchanged. They must expire, within 366 days. On each use,
517 identity cuts the resolved person down to the token's reach
518 (`apply_reach`); `access::granted` gives no role outside it, so a public
519 repository elsewhere still reads and nothing more.
520- **Governance** (`token_policies`, `token_workspace_revocations`): per
521 workspace, allow classic, allow fine-grained, require approval (on by
522 default, as GitHub's; owners' own tokens never wait), the longest
523 lifetime, and forbidding tokens that never expire. Owners see every
524 member's token that can reach the workspace, approve or deny pending
525 fine-grained ones (inbox: `token.approval_requested` and
526 `token.approval_reviewed`, the inbox's first notices about no
527 repository), and revoke one there. REST and MCP for owners; audited as
528 `token.*`.
529- **Workflow files** need `workflow_files:write` (GitHub's `workflow`
530 scope; the `workflows` permission) from any token, checked commit by
531 commit on push (`services/repos/src/workflow_gate.rs`) and on files g1t
532 writes for a token. A job's token never has it. g1t's agents push with
533 run credentials, not tokens, and are not gated by it; their work arrives
534 as pull requests people review.
535- **Workspace tokens** have Write unless an owner gives Admin at creation.
536- **Deploy keys** (identity/0035): per repository, read-only unless write
537 is ticked; resolved to a principal bound to the one repository.
538 Serving git over SSH is still to come, so nothing uses them yet.
539- **Packages** (packages/0006, `services/packages/src/access.rs` and
540 `settings.rs`): per-package roles (read, write, admin) for people and
541 teams, with "inherit access from the linked repository" (on by default);
542 "Manage Actions access", which a job's token is held to (its own linked
543 repository writes; any other repository needs an entry, added
544 automatically for the repository whose job first publishes an unlinked
545 package); linking by `org.opencontainers.image.source` (manifest
546 annotation or image label, same workspace, pusher may push there); 30-day
547 soft delete of packages and versions, registry deletes included (the name
548 and version stay reserved), restore, and a purge in the hourly cron; a
549 settings tab and a "Deleted packages" view; 17 REST operations and one
550 `package` MCP tool (reads `packages:read`; settings and access
551 `packages:write` with the package's Admin role; delete and restore
552 `packages:delete`); and download counts per version in every registry.
553 Existing unlinked packages have no Actions access entries, so workflows
554 that used them through `G1T_TOKEN` need one added.
555
556### Keeping workflow runs safe (built 2026-10-08)
557
558An audit of g1t Actions found a job's token was a full-access workspace
559token, environments had no protection, outside pull requests ran at once,
560the cache could be poisoned across branches, a job's token could set off
561more runs, and masking missed multi-line and encoded secrets. Now:
562
563- **The job's token** (`G1T_TOKEN`, `GITHUB_TOKEN`) is minted per job by
564 identity (`create_job_token`, migration identity/0030): it reaches its
565 repository only (`TokenAccess.repo`, enforced by the API, git and the
566 registries), carries the scopes its `permissions:` map to
567 (`g1t_actions::permissions`), is revoked when the job ends, and its
568 writes are audited with the run as `run_kind: workflow_job`. Without
569 `permissions:` it gets the repository's default, the GitHub way:
570 repositories that existed when actions/0007 ran keep read and write,
571 newer ones take their workspace's default (read-only unless an owner
572 says), and a workspace can cap every repository at read-only. An outside
573 pull request's is read-only. "Allow g1t Actions to create and approve
574 pull requests" (repository and workspace, off by default) decides whether
575 the token may open or approve pull requests. OIDC (`id-token: write`)
576 reads the same permissions model.
577- **No loops.** Work and repos mark the events a job's token causes
578 (`causedByJob`), carried on to a pull request it moves; the actions
579 service starts nothing for them. `workflow_dispatch` and
580 `repository_dispatch` (now sent by `POST {repo}/dispatches`) still start
581 runs.
582- **Environments' protection rules** (actions/0007): required reviewers
583 (people or teams, up to six, optionally not whoever started the run), a
584 wait timer, which branches and tags may deploy, and admin bypass. A job
585 naming one is `pending` once its needs are done, its environment read
586 then (an expression included); reviewers hear in the inbox
587 (`deployment.review_requested`) and approve on the run's page or through
588 `pending_deployments`; secrets are read only when the job starts.
589- **Approval for outside pull requests**, by a repository policy
590 (first-time contributors, outside contributors (the default), or every
591 external contributor): such runs are `action_required` until someone with
592 Write approves them.
593- **The cache is scoped by ref** (own, then the pull request's base, then
594 the default branch; outside pull requests save where nothing else reads)
595 and versioned by its paths and compression (0006's toolkit `version`,
596 which g1t's runner now sends too); g1t's `actions/cache` and the
597 toolkit's protocols share one scope rule. Entries from before were
598 expired.
599- **Masking** covers each line of a multi-line secret, base64 at every
600 offset and JSON-escaped forms; outputs holding a secret are withheld and
601 annotations masked.
602- A job's own `concurrency:` is honoured, `create` runs on new branches and
603 tags, and `on: delete` says plainly that it never runs yet.
604
605### Docker in workflow jobs (built 2026-10-08)
606
607> **2026-10-08:** "Why didn't we give CI docker then? We need GitHub
608> Actions functionality maxxed baby but with all the good good security
609> etc." The trigger: `deploy.yml`'s runner-image job needs `docker build`
610> and `docker push`, and failed on hosted runners.
611
612**What Cloudflare Containers allow** (their FAQ, updated 2026-10-05, and
613the Docker-in-Docker guide and example it links):
614
615- Docker runs inside a container: `docker:dind`, with `dockerd` as
616 **root**. A rootless Engine does not start there.
617- **No iptables**: `--iptables=false --ip6tables=false`, or the Engine
618 fails setting up its rules. Containers with the `durable_object`
619 scheduling policy (ours: each sandbox is a Durable Object's) cannot turn
620 IP forwarding on either: `--ip-forward=false`, or the Engine exits.
621- So **a bridge network has no way out**: the guide's answer is
622 `--network=host` for `docker run` and `docker build`, which gives
623 containers the outer container's network.
624- Built images and containers are lost when the sandbox stops.
625
626**What was found by trying** (Docker Engine 29.8.2 in a privileged
627container standing in for a sandbox, with the same flags):
628
629- `--bridge=none` makes BuildKit's `RUN` steps fail outright ("network
630 bridge not found"); with the default bridge they run with no route out.
631 Containers default to the bridge too. The default bridge is created
632 fine without iptables, as the FAQ's own example relies on.
633- The overlay snapshotter does not work on an overlay root filesystem, and
634 the containerd image store does not fall back by itself: the Engine
635 starts, then every container fails to mount. Whether a sandbox's disk
636 takes overlays is not documented, so the runner tries a mount first and
637 uses `native` (plain copies) when it fails. `vfs` is not a name the
638 containerd store accepts.
639- `--cpus` and `--memory` need cgroup v2 controllers handed down from a
640 cgroup with no processes, which `docker:dind`'s entrypoint does and a
641 plain `dockerd` does not.
642- A `runc` earlier on the Engine's `PATH` is used both for containers (via
643 containerd's shim) and by BuildKit's executor, with the bundle's
644 `config.json` written before it runs. BuildKit's bridged steps carry
645 libnetwork's `libnetwork-setkey` prestart hook; `RUN --network=none`
646 does not.
647- Buildx skips `type=gha` caches when the job has no GitHub cache service,
648 and the build succeeds without one.
649- Registries' layer hosts: Docker Hub sends layers from
650 `production.cloudfront.docker.com` (and `production.cloudflare.docker.com`),
651 Quay from `cdn0N.quay.io`, Microsoft's from regional
652 `*.data.mcr.microsoft.com`, public ECR from a CloudFront host;
653 `mirror.gcr.io` serves its own.
654
655**What was built** (`crates/runner/src/docker`, `actions/containers.rs`):
656
657- **One Engine per job, started lazily.** The runner listens on
658 `/var/run/docker.sock` itself and starts `dockerd` (root, the flags
659 above, containerd image store, `mirror.gcr.io` first for Docker Hub) on
660 the first connection, or when the job has `services:` or `container:`.
661 A log line says it started and how long it took.
662- **Containers on the job's network.** The socket is an API proxy: a
663 container that asks for a bridge or user network gets `host`; its names
664 (container name, aliases, Compose service, links) resolve to 127.0.0.1
665 in later containers (`ExtraHosts`) and in the job's steps
666 (`/etc/hosts`); `-p 8080:80` is forwarded; `docker inspect` reports the
667 ports as published; `network connect` adds aliases. Sharing the job's
668 network is also what keeps the guardrails on every container: the
669 egress Worker sees their traffic as the job's.
670- **A `runc` shim.** The runner binary, as `runc`: BuildKit steps bound for
671 a bridge lose the network namespace and the libnetwork hook (so they use
672 the job's network); in a guarded job every container (run, exec, build
673 step) gets the egress certificate at `/dev/g1t-egress` and the
674 variables that point tools at it. `/dev` is the container's own tmpfs,
675 so none of it lands in a layer; checked by saving a built image.
676- **Job features:** `services:` (pull, credentials, health waits, logs at
677 the end, `job.services.*`), `container:` (steps and JavaScript actions
678 through `docker exec`, Node mounted from the runner, Alpine falls back to
679 running actions beside it), `docker://` steps and Dockerfile actions in
680 GitHub's `/github/*` layout, `docker/setup-buildx-action` answered
681 natively (the job's Engine is the builder), sign-in to g1t's registry
682 with the run's token.
683- **Kill switch:** the runner Worker's `DOCKER` var (`off`).
684
685**Rejected:** rootless Docker or BuildKit (does not start in Containers);
686Podman or buildah with `vfs` (no better networking, less compatible, slow);
687a standalone `buildkitd --oci-worker-net=host` as the default builder
688(images not in the Engine's store, so `FROM` a just-built image and
689`docker run` of a build fail without `--load` round trips); a `docker` CLI
690wrapper adding `--network=host` (misses Compose, SDKs and testcontainers,
691which speak the API).
692
693**Not yet:**
694
695- Seen on Cloudflare itself: whether a sandbox's disk takes overlays,
696 `--privileged`, and the first deploy's pull of the base from
697 `registry.cloudflare.com` (its layer host may need a workflow-only line).
698- `type=gha` build caches backed by g1t's Actions cache.
699- Multi-platform builds (QEMU's `binfmt_misc` in a sandbox).
700- Docker for agents and checks, not just workflow jobs.
701- `runner-base.yml` on g1t's machines: the base's apt step needs
702 `Acquire::https::CAInfo` pointed at the egress certificate first.
703- A deploy that appends the runner binary as a layer through the registry
704 API, with no Docker and no 3 GB pull.
705
706Agents can also reach integrations directly: an agent definition lists MCP
707servers (Sentry, Linear and so on) it may use while working.
708
709### Workflows: the toolkit, OIDC and artifacts
710
711> **2026-10-08:** built so that workflows that deploy, cache and pass files
712> run unmodified.
713
714- **The toolkit's services.** Every job gets `ACTIONS_RUNTIME_TOKEN` (a
715 JWT whose `scp` names its run and job, signed with a key derived from
716 the job's own token, so nothing new is kept), `ACTIONS_RESULTS_URL`,
717 `ACTIONS_CACHE_URL` and `ACTIONS_CACHE_SERVICE_V2`. The API answers the
718 cache's Twirp service (v2) and its older REST protocol, the artifact
719 Twirp service, and the signed blob links they hand out (a subset of
720 Azure Blob's protocol mapped onto R2 multipart uploads), from the same
721 cache and artifact rows g1t's own runner uses. As the clients' source
722 reads, `@actions/cache` and `@actions/artifact` treat any server
723 but github.com as GitHub Enterprise Server, so the cache client speaks
724 the older protocol and the artifact client refuses to run. g1t's runner
725 therefore keeps handling `actions/upload-artifact`, `download-artifact`
726 and `upload-artifact/merge` itself; the Twirp artifact service is there
727 for clients that do not check.
728- **OIDC.** The issuer is `{API}/actions/oidc`, the API's own host, with
729 discovery, JWKS (RFC 7638 `kid`s, a previous key published while
730 rotating) and a token endpoint for `core.getIDToken`. Claims follow
731 GitHub's. A job gets one only when its permissions (or its workflow's)
732 give `id-token: write`, and never for an untrusted run. The permission
733 check reads only `id-token` (`services/actions/src/runtime.rs`,
734 `id_token_permitted`), the seam for the full `permissions:` model.
735- **Artifacts** moved from KV to R2 (`a/` in the cache bucket), with rows
736 in the actions service: numeric ids, 5 GiB each and 10 GiB a run,
737 zipped by the runner, `retention-days` up to the repository's setting
738 (1 to 90, 14 by default), `overwrite`, `compression-level`, patterns,
739 merging and other runs of the same repository. The REST artifacts API and
740 the `workflow` tool's artifact actions follow GitHub's shapes; the run's
741 page lists them with size and expiry, with download and delete. Their
742 storage is charged with the cache's.
743- **Later:** the toolkit's older artifact protocol (`upload-artifact@v3`
744 inside other actions), downloads from other repositories, and npm
745 trusted publishing, which depends on npm accepting g1t's issuer.
746
747### Actions parity: other repositories, triggers, step timeouts (built 2026-10-08)
748
749- **Other repositories' actions and reusable workflows**
750 (`services/actions/src/reach.rs`, actions/0008): `uses: owner/repo@ref`,
751 `owner/repo/path@ref` and `jobs.<id>.uses: owner/repo/.g1t|.github/workflows/x.yml@ref`
752 are looked for on g1t first, as the calling workspace sees them. Same
753 repository or public: used. Private: only from a private repository of
754 the same workspace, when its **Settings → Actions → Access** (`access_level`,
755 `GET`/`PUT …/actions/permissions/access`, MCP `get_access`/`set_access`)
756 says `organization`; a job fetches such an action with a read-only token
757 for that repository, revoked with the job (`job_action`, the runner's
758 `POST /actions/jobs/{job}/action`). Not on g1t: actions from GitHub as
759 before, reusable workflows from a public GitHub repository. A `./` call
760 inside a called workflow reads from that workflow's own repository.
761- **Secrets for called workflows** follow GitHub: none but the job token
762 unless the caller passes `secrets:` by name or `secrets: inherit`;
763 required secrets are checked before the call; a called job's
764 `environment:` reads that environment's secrets over what was passed. The
765 mapping is kept with the called jobs and read when each starts, so no
766 secret is stored. (Before, same-repository called workflows read every
767 repository secret.)
768- **Triggers:** `release` (created, published, released, prereleased,
769 edited, unpublished, deleted; repos now publishes `release.*`),
770 `deployment` and `deployment_status` (from the deployments service's
771 events; ones an Actions job or a job token made are marked
772 `causedByJob` and start nothing), `pull_request` `reopened` and
773 `converted_to_draft`, `issue_comment` `edited` and `deleted` (work
774 publishes `pull.reopened`, `pull.converted_to_draft`, `comment.edited`
775 and `comment.deleted`).
776- **`timeout-minutes` on every step**, `uses:` included: the runner keeps a
777 step deadline every process it starts stops by, nested composite steps
778 taking the nearer one.
779- **Not yet:** a deployment's `ref` that is neither a branch nor a commit
780 is read as a tag; `on: delete`.
781
782### Runs: summaries, attempts, cancelling, logs and badges (built 2026-10-08)
783
784GitHub Actions parity on the run itself:
785
786- [x] **Job summaries.** The runner sends each step's
787 `$GITHUB_STEP_SUMMARY`, masked, as a `summary` report (1 MiB a step,
788 20 steps a job, kept in `job_summaries`, actions/0009); the run's page
789 renders them as sanitised Markdown, a card per job.
790- [x] **Attempts and re-runs.** A re-run is a new attempt that keeps the
791 one before (`run_attempts`, `job_attempts`; a re-run job's logs and
792 summary move to `{job}.{attempt}`, which is its id when that attempt is
793 viewed). Re-run all, failed, or one job (`POST …/jobs/{job}/rerun`) with
794 the jobs that need it; a matrix or a called workflow runs again whole.
795 Debug re-runs set `RUNNER_DEBUG=1`, `ACTIONS_STEP_DEBUG`,
796 `ACTIONS_RUNNER_DEBUG` and `runner.debug`; the runner then shows
797 `::debug::` lines and how each step's `if:` read. An attempt picker on
798 the run's page, `attempt` on `get_workflow_run` and
799 `…/runs/{id}/attempts/{n}`.
800- [x] **Graceful cancel.** A running job gets `cancel_requested_at`,
801 told in the answer to its next report (a quiet step pings every 10 s):
802 the step's process group gets SIGINT, SIGTERM at 7.5 s, SIGKILL at 10 s;
803 then only `always()`/`cancelled()` steps and post steps run, and the job
804 ends `cancelled`. Hard-stopped after 5 minutes; cancelling again or
805 `…/force-cancel` stops at once.
806- [x] **Logs.** Search on the run's page (matching lines, groups opened);
807 one job's log as text (`…/jobs/{job}/log.txt`, API
808 `…/jobs/{job}/logs?format=text`) and an attempt's as a zip laid out as
809 GitHub's (`…/runs/{id}/logs.zip`, API `…/runs/{id}/logs`), up to 24 MiB.
810- [x] **Status badges** at `/{ws}/{repo}/actions/workflows/{file}/badge.svg`
811 with `branch` and `event`; public repositories' for anyone (cached a
812 minute), private ones' only for viewers who can see them. "Create status
813 badge" on the workflow's page gives the Markdown.
814- Not yet: re-running one combination of a matrix alone; signals into a
815 job container's processes on cancel (they reach `docker exec` only).
816
817### Runner image: Java, .NET and Ruby (built 2026-10-08)
818
819The base (`services/runner/base/Dockerfile`) adds Temurin 21, the .NET 8
820SDK and Ruby 3.3, placed where the setup actions look so common workflows
821run unmodified and download nothing:
822
823- **Java** in `RUNNER_TOOL_CACHE/Java_Temurin-Hotspot_jdk/<semver, + as
824 ->/x64` with `x64.complete`; `JAVA_HOME`, `JAVA_HOME_21_X64` and `PATH`
825 set. `actions/setup-java` (`temurin`, `21`) resolves it from the cache.
826- **.NET** in `/usr/share/dotnet` (setup-dotnet's Linux install dir),
827 owned by `node`; `DOTNET_ROOT` set, telemetry off. `setup-dotnet` with
828 `8.0.x` keeps it while it is the newest 8.0 SDK, else installs beside it.
829- **Ruby** built from source into `RUNNER_TOOL_CACHE/Ruby/<v>/x64` with
830 `x64.complete`, on `PATH`. On Debian, `ruby/setup-ruby` counts as
831 self-hosted and uses only the tool cache, so any version but 3.3 fails
832 (documented in limitations).
833
834**`gh`: not installed.** With `GH_HOST=g1t.sh`, `gh` treats g1t as
835GitHub Enterprise Server: REST under `https://g1t.sh/api/v3` and GraphQL at
836`https://g1t.sh/api/graphql`. Both are 404 today (the API is REST at
837`api.g1t.sh`, and `GITHUB_GRAPHQL_URL` is empty), and `pr`, `issue`, `repo`
838and `run` are GraphQL-first, so even `gh api` alone would need the
839`/api/v3` prefix. Jobs call the API with `curl` and `$GITHUB_API_URL`
840(documented in the Actions guide).
841
842**Later:** to make `gh` useful, `g1t.sh/api/v3/*` proxying to the REST API
843(enough for `gh api` and `gh auth status`), then a GraphQL subset for the
844`pr`/`issue` read paths. Ship `gh` in the base only once those exist.
845More preinstalled Rubies (3.2, 3.4) if workflows ask, at roughly 75 MB
846each. `setup-dotnet@v5` first installs the current LTS .NET runtime (10,
847a 36 MB download) every run before finding SDK 8 already there;
848preinstalling that runtime would skip it.
849
850**Size:** the base went from 3.18 GB to 4.52 GB as `docker image inspect`
851reports it (813 MB to about 1.2 GB compressed): Temurin 308 MB (without
852`src.zip`), .NET 512 MB (without the SDK's translations), Ruby 74 MB,
853headers and ICU 44 MB.
854
855## A repository that maintains itself
856
857> **2026-10-04:** the user asked for Dependabot, GitHub Advanced Security and
858> Vercel-style deployments, "so you're not having to maintain shit and you're
859> just pushing up agents that are delivering work consistently".
860
861GitHub reports problems and leaves the fix to you. In g1t, an agent opens an
862issue for each problem, writes the fix, runs its checks, links a preview and
863lands it through the queue. People only decide.
864
865### Upkeep agents
866
867- **Dependency updates.** The file is `dependabot.yml` version 2, read from
868 the default branch at `.g1t/dependabot.yml` (or `.yaml`), then
869 `.github/dependabot.yml` (or `.yaml`); `.g1t/` wins when both exist, and
870 an imported repository's file works unchanged. Every option is read and
871 checked, each problem reported with its line and key on the Security page
872 and as the `g1t / dependabot.yml` status on pull requests that change the
873 file; a file with problems is not acted on.
874 - **Built (2026-10-07):** version updates for npm, cargo, gomod and pip:
875 schedules (all intervals, cron and natural phrases, time zones, a
876 picked time per repository), allow, ignore, cooldown (3 days by
877 default), groups (including across directories and `group-by`),
878 versioning strategies, open-pull-requests-limit, commit-message,
879 branch names, rebase-strategy, assignees, reviewers, private
880 registries filled from workflow secrets (npm, cargo, Go proxy, Python
881 index), and the `@g1t` comment commands. Pull requests come from g1t
882 with an `updated-dependencies` commit record and land through the
883 required checks; one that fails them is closed and becomes a
884 "needs code changes" issue assigned to g1t.
885 - **Security updates follow the same file:** ignore (and comment
886 ignores), allow names, `applies-to: security-updates` groups,
887 commit-message, assignees, reviewers, labels and milestone. Cooldown
888 and the open pull request limit do not apply. The Security updates
889 switch still turns them on and off.
890 - **Labels, milestone and target-branch** are applied to version
891 updates: `dependencies` and the ecosystem's label by default, missing
892 labels created; `target-branch` updates are made from that branch and
893 merge into it.
894 - **Not done yet:** one pull request for a multi-ecosystem group
895 (it opens one per ecosystem); registries that sign in with OIDC;
896 updating vendored copies; and version updates for the other
897 ecosystems (bundler, composer, docker, github-actions, gradle, maven,
898 nuget, terraform, uv and the rest are read and checked only).
899- **Secret scanning.** Pushes are scanned for known token formats. A push
900 that adds a secret is refused with the file and line; one already in
901 history opens an issue to rotate it and remove it.
902- **Vulnerability alerts.** Dependencies are matched against the OSV
903 database. Every alert links to the issue and pull request fixing it.
904- **Code scanning.** A reviewer agent reads each pull request's diff for
905 security problems and leaves findings as review comments with a
906 suggested fix. Findings on `main` open issues.
907- **A security page per repository** lists alerts, secrets and findings,
908 with the agent work on each, like GitHub's Security tab.
909
910All of these are event sources for the existing issue → agent → checks →
911queue pipeline; they need no new kind of work.
912
913### The security suite (built 2026-10-07)
914
915GitHub Advanced Security's depth, in g1t's shape (services/security,
916`g1t_contracts::security_suite`, docs `guides/security/*`):
917
918- **Secret protection.** Custom patterns (repository and workspace; Rust
919 `regex`, linear time, size-limited; test strings; dry run over the
920 default branch) used by push protection, `commit_file` and history
921 scans. Bypass with a reason (false positive, used in tests, will fix
922 later), recorded on the alert and in the audit log; delegated bypass
923 (requests reviewed by owners and repository admins, through the inbox).
924 Validity checks for GitHub, GitLab, Stripe, Slack, npm, OpenAI,
925 Anthropic and SendGrid tokens, made by the repos service, which reads the
926 landed secret again: the value never leaves it except to the issuer. AWS
927 keys (need their secret key to sign) and webhook addresses (would post)
928 are the extension points left (`g1t_scan::validity::check_for`).
929- **Code scanning.** SARIF 2.1.0 uploads → alerts with fingerprints (tool
930 partial fingerprints first), fixed when no longer reported; pull request
931 uploads → line comments and the `Code scanning` commit status, gated by a
932 per-repository threshold and required like any check. Starter workflow:
933 a scanner per language present, each uploading its own category: Bandit
934 (Python), gosec (Go), ESLint + eslint-plugin-security with the SARIF
935 formatter (JS/TS), Clippy + clippy-sarif (Rust); all install from the
936 registries the runner's egress already allows. Semgrep's registry rules
937 and the Opengrep rules fork are not usable in a paid feature, so neither
938 is used. "Fix with g1t" opens an issue and runs the agent.
939- **Supply chain.** Dependency graph (direct/transitive where the lockfile
940 says, npm licenses), SPDX 2.3 SBOM, `Dependency review` status on every
941 pull request (OSV severity threshold, license deny list, summary comment).
942- **Overview.** Workspace totals, opened/closed, a daily snapshot trend,
943 coverage, repositories most in need first.
944- **Paid.** The Security and quality activation on private repositories;
945 free on public ones; the free core (secret scanning, push protection,
946 vulnerability alerts, security updates, dependency graph) free everywhere.
947
948Not built yet:
949
950- **The reviewer agent as an analysis source.** g1t's reviewer reads each
951 pull request's diff (`agent_review`), but its findings are review
952 comments, not SARIF. Next: have it emit SARIF for the security issues it
953 finds and upload them as the tool `g1t review`, so they become alerts and
954 count toward the Code scanning check.
955- **Repository security advisories.** Private advisories, draft →
956 published, with affected versions (ranges per ecosystem), severity and a
957 CVSS vector, credits, and a private fork (a `g1t/advisory/GHSA-…` working
958 copy only the advisory's collaborators can see) for the fix, merged into
959 the default branch when the advisory publishes. Published advisories
960 should feed the OSV-shaped data other g1t repositories' vulnerability
961 alerts read. CVE requests are out of scope. Needs: an `advisories` table
962 per repository, a collaborator list per advisory, the private-fork
963 visibility rule in repos, and an Advisories page on the Security tab.
964- **SARIF upload as a background job.** Uploads are read in the request
965 (10 MB encoded, 40 MB unzipped, 5,000 results); larger ones need a queue.
966
967### Deployments
968
969- **A preview for every pull request**, at
970 `<pr>--<repo>--<owner>.g1t.page`, linked on the pull request and updated
971 on each push. `main` deploys to `<repo>--<owner>.g1t.page`, and a
972 repository can add its own domain.
973- **On g1t.page, not g1t.sh,** so customer code never shares cookies or an
974 origin with the site people sign in to.
975- **Built on Workers for Platforms.** Each deployment is a user Worker in a
976 dispatch namespace; one dispatch Worker on `*.g1t.page` routes to it. The
977 build runs in the same runners as Actions. Static sites and Workers apps
978 first; container apps and databases later.
979- **Agents use the preview.** The reviewer agent opens the preview in a
980 browser, takes screenshots of what changed and attaches them to its
981 review, so an approver sees the result without reading the diff.
982- **Environments.** Preview, production and their secrets; deploy history
983 and one-click rollback.
984- **Scale to zero.** An idle branch costs neither g1t nor the customer
985 anything: a Worker runs, and is billed, only while it answers a request.
986 A preview is deleted when its pull request closes or merges, and after
987 a set number of idle days. Container apps, later, sleep when idle.
988- **Billed to the customer, never free.** The user (2026-10-04): "we
989 should not be giving any of this available for free". Every deployment
990 is metered per workspace (requests, CPU time, deployed apps, stored
991 data), priced at Cloudflare's cost + 20% like agent usage, and drawn
992 from prepaid credit. `FREE_WHILE_BUILDING` and the free model allowance
993 do not cover deployments: a workspace without credit cannot deploy, and
994 turning deployments on says so first.
995- **Turning them on is a paid plan, the way Cloudflare's is.** "Including
996 things like them even enabling the feature should have that pay like
997 Cloudflare does." Enabling deployments for a workspace starts a monthly
998 fee that includes an allowance of requests, CPU time and deployed apps;
999 usage past it is billed per unit, as Workers for Platforms bills g1t.
1000 The fee and allowance are the user's to set.
1001- **Recommended, off in one click.** Because enabling costs money, it is
1002 never switched on without the workspace agreeing: new repositories
1003 recommend it prominently. A repository can turn it off, keep only production, or
1004 deploy somewhere else from its own workflows. Apps built for Cloudflare
1005 (Workers, static assets, D1, KV, R2) deploy without configuration.
1006
1007Later, toward GitLab's DevOps breadth: package and container registries,
1008releases, container hosting. (Environments' protection rules for g1t
1009Actions were built on 2026-10-08; see above.)
1010
1011## Projects
1012
1013> **2026-10-04:** the user: "an extra dimension of Projects so it's not
1014> just repositories … where a lot of things can live", "very Vercel
1015> like", with dependencies across projects "the Platform Engineering /
1016> Port route", and "the repository is *part* of a project: you could be
1017> mirroring it from GitHub/GitLab/Bitbucket, or you could let us host it
1018> for you", with room for Mercurial or anything else later.
1019
1020**A project is the thing you are building and running; a repository is
1021where some of its code lives.** Everything that is about running software
1022(deployments, environments, domains, secrets, dependencies, owners,
1023health, upkeep) belongs to the project. What is about the code itself
1024(branches, pull requests, review, merge rules) stays with the repository.
1025That split is what lets the code live anywhere.
1026
1027### The model
1028
1029| | What it is | Like |
1030| --- | --- | --- |
1031| **Workspace** | The company or team. Members, billing, plans, shared secrets. | Vercel team, GitLab group, GitHub org |
1032| **Group** | An optional named set of projects, one level: "Payments", "Mobile". For browsing, ownership and shared settings. | GitLab subgroup, Backstage system, Port domain |
1033| **Project** | One deployable thing: a site, an API, a worker, a library. Has exactly one **source**. | Vercel project, Port service, Backstage component |
1034| **Source** | Where its code is: a repository and a **root directory** in it. | Vercel's connected repo + root directory |
1035| **Dependency** | Project A uses project B: calls its API, consumes its package, reads its queue. | Port relations, Backstage `dependsOn` |
1036
1037- **One project, one source; one repository, any number of projects.** A
1038 project builds from exactly one place, which keeps it as simple as
1039 Vercel's. A monorepo is several projects on one repository, each with
1040 its own root directory (`apps/web`, `services/api`), and a push builds
1041 only the projects whose root it touched. The common case stays 1:1, and
1042 every existing repository gets a project of its own name when this
1043 ships, so nobody has to set anything up.
1044- **Groups are for people; dependencies are for software.** Groups decide
1045 where a project shows up and who owns it. Dependencies decide what
1046 happens when one changes. Neither replaces the other, and a dependency
1047 can cross groups.
1048
1049### Sources: where the code lives
1050
1051A source is an adapter behind one interface (`SourcePort`: clone URL,
1052branches, commits, pushes as events, pull requests if it has them):
1053
1054| Source | Code lives | g1t gets pushes by | Pull requests |
1055| --- | --- | --- | --- |
1056| **Hosted on g1t** (today) | Artifacts | its own events | g1t's, with agents, the queue, review |
1057| **Mirrored** from GitHub, GitLab or Bitbucket | Both; g1t keeps a copy | the provider's webhook, then fetch | The provider's, read into g1t; agents open theirs there |
1058| **Connected, not copied** | The provider only | webhook | The provider's |
1059| **Later:** Mercurial, Perforce, a tarball upload | Behind the same port | per adapter | per adapter |
1060
1061A mirrored or connected project still gets everything that is the
1062project's: previews on its pull requests (a status and a comment on
1063GitHub's), production on its default branch, secrets, dependencies,
1064upkeep agents. That is the on-ramp: a team keeps GitHub and gets g1t's
1065deployments and agents first, and moves the code later or never.
1066Bring-your-own-git is also why the project, not the repository, holds the
1067URL `g1t.sh/<workspace>/<project>`.
1068
1069### What lives on a project
1070
1071| | Today it is on | Moves to the project |
1072| --- | --- | --- |
1073| Deployments: production, previews, build settings, root directory, framework | The repository | Yes |
1074| Environments: production, preview, and custom ones (`staging`) with protection rules (required approvers, branch limits) | Nowhere yet | New, on the project |
1075| Domains: `<project>--<workspace>.g1t.page`, and custom domains | The repository's name | Yes |
1076| Secrets and variables | The repository | Yes. Workspace rows link to projects instead of repositories. A repository's workflows read the rows of its project (with several projects on one repository, the one marked as the repository's default). |
1077| Dependencies | Nowhere | New |
1078| Owners, on-call, links (docs, dashboards, runbooks) | Nowhere | New: the catalog's metadata |
1079| Health: scorecards (has an owner, CI passes, dependencies current, no open security alerts, deploys within N days) | Nowhere | New |
1080| Upkeep agents: dependency updates, security alerts | The plan | Scoped per project |
1081| Logs and analytics of the running app | Nowhere | New: requests, errors and CPU per environment, from Workers analytics |
1082| Branches, pull requests, review, merge rules, the queue, webhooks | The repository | Stay |
1083
1084### Dependencies: why this gets powerful
1085
1086Declared in the UI, or in the source as `.g1t/project.yml` (which wins
1087when present, as `catalog-info.yaml` does in Backstage):
1088
1089```yaml
1090name: web
1091root: apps/web
1092dependsOn:
1093 - project: api # calls its HTTP API
1094 as: API_URL # its URL, per environment, as a variable
1095 - project: ui-kit # consumes its package
1096```
1097
1098What g1t does with them:
1099
11001. **Reference variables.** `API_URL` above resolves to `api`'s production
1101 URL in production and to the matching preview in a preview, the way
1102 Railway's `${{ api.URL }}` references work. No hard-coded URLs.
11032. **Preview stacks.** A pull request on `api` gets its own preview, and
1104 **Preview with dependents** builds `web`'s preview pointed at it, so a
1105 reviewer clicks through the whole change across projects. A change that
1106 spans repositories (one issue, one fork per repository) gets one stack.
11073. **Release order.** Production deploys go out in dependency order; a
1108 change set across projects lands through the queue together or not at
1109 all.
11104. **Impact on every pull request.** "Changes `api`; `web` and `mobile`
1111 depend on it." Agents get the graph in their context: an agent
1112 changing an API opens follow-up issues on the projects that call it,
1113 and reviewers see what else could break.
11145. **Upkeep across the graph.** A vulnerable package in `ui-kit` opens
1115 issues, assigned to agents, on every project that consumes it.
11166. **Scorecards turn into work.** A project failing a scorecard check
1117 ("no owner", "dependencies 90 days old") gets an issue an agent can fix.
1118 That is the Port idea with the work done for you.
11197. **The map.** A workspace's projects as a graph, coloured by health and
1120 by what is deploying now.
1121
1122### Pages
1123
1124- `g1t.sh/<workspace>`: projects first (grouped, with health and
1125 production status), then repositories.
1126- `g1t.sh/<workspace>/<project>`: overview (production, latest previews,
1127 health, owners, dependencies both ways), **Deployments**,
1128 **Environments**, **Secrets and variables**, **Logs**, **Settings**
1129 (source, root directory, build, domains, groups, owners).
1130- A hosted repository keeps its code pages; from a project they are its
1131 **Code** tab. A repository page lists the projects built from it.
1132
1133### Services
1134
1135- `services/projects` (new): projects, groups, sources, dependencies,
1136 owners, scorecards. Events `project.created`, `project.updated`,
1137 `dependency.changed`.
1138- `services/deployments`: keyed by project instead of repository.
1139- Secrets and variables: the scope becomes workspace → project.
1140- Sources: the hosted adapter wraps `services/repos`; a mirror adapter
1141 per provider in `services/integrations`, which already holds those
1142 connections.
1143
1144### Build order
1145
11461. **Projects as the home of deployments and secrets**, 1:1 with every
1147 existing repository: the service, the pages, deployments and secrets
1148 moved to the project, `<project>--<workspace>.g1t.page`.
11492. **Dependencies:** declared in the UI and `.g1t/project.yml`, reference
1150 variables, impact on pull requests and in agents' context, the map.
11513. **Preview stacks** and cross-project change sets.
11524. **Monorepos:** several projects on one repository, each with a root
1153 directory, building only what a push touched.
11545. **Mirrored sources:** GitHub first, then GitLab and Bitbucket.
11556. **Groups, owners, scorecards** feeding the upkeep agents.
11567. **Environments** with protection rules; custom domains; logs.
1157
1158**Step 1 shipped 2026-10-04:** `services/projects`; every repository a
1159project of its own name; the site projects-first (workspace page of
1160project cards, the project overview at `g1t.sh/<workspace>/<project>`, code
1161under `/code`, the sidebar and the New project flow); deployments keyed by
1162project and branch at `<project>-<workspace>.g1t.page` and
1163`<project>-git-<branch>-<workspace>.g1t.page`; secrets and variables owned
1164by the project.
1165
1166**Step 5, GitHub, built 2026-10-05:** one GitHub App (`g1t-sh`) for both
1167sign-in and repository access. Sign-in is its user authorization with PKCE
1168(identity, `src/github.rs`): accounts known by GitHub's numeric id, a
1169matching verified email never linked without signing in to the account,
1170new accounts behind the invite check. Repositories come through its
1171installations (integrations, `src/github.rs`), copied with every branch and
1172tag by the repos service (`src/mirror.rs`) as **import**, **mirror** (g1t
1173follows GitHub on its push webhook) or **move to g1t** (GitHub follows g1t
1174on `git.push`). A mirror is a hosted repository that keeps a full copy, so
1175its project stays `hosted` and deploys like any other; the tie lives in
1176integrations' `github_repos`. Not yet: previews and statuses on GitHub's own
1177pull requests, comments and pull requests copied, GitLab and Bitbucket.
1178
1179### People and search
1180
1181> **2026-10-04:** "pull up user profiles, using a /u/username prefix kinda
1182> like DockerHub … search for users if you search that explicitly, how
1183> GitHub has the aside for searching against filters … a significantly
1184> stronger implementation."
1185
1186- **Profiles at `g1t.sh/u/<username>`**, apart from workspaces at
1187 `g1t.sh/<workspace>`: who they are, their workspaces, recent work,
1188 agents' sessions they steered.
1189- **Search with a filter sidebar:** Projects, Code, Issues, Pull requests,
1190 Users, Workspaces, each with its count; filters by workspace, language,
1191 state, author, agent, label, date; qualifiers in the query
1192 (`user:`, `is:open`, `agent:g1t`) as on GitHub. Typing `u/name`
1193 searches people directly, as Docker Hub does.
1194
11951 and 2 serve the competition directly (multi-agent coordination across
1196projects is 25% of the score); 3 is the demo's best moment if time allows.
1197
1198## Billing model
1199
1200> **2026-10-04:** "Some things just require you to have a card on file …
1201> some things will be something you give us an initial amount of money
1202> per month just to activate, tons of things additionally will be usage
1203> based, some things will just be usage based only … at minimum a
1204> breakeven with Cloudflare costs, or in some cases a value add." Stripe
1205> moves to Flagon, Inc. (g1t.sh is its product). Proposed below; the
1206> prices are the user's to confirm.
1207
1208### Four kinds of charge
1209
1210Every feature is exactly one of these, and the Billing page says which:
1211
1212| Kind | What the workspace does | Example |
1213| --- | --- | --- |
1214| **Free** | Nothing | Hosting code, issues, pull requests, review, the merge queue, bringing your own agent over MCP |
1215| **Card on file** | Adds a card; pays only for what it uses | Previews, g1t's agents, workflow minutes |
1216| **Activation** | Turns a feature on for a monthly fee that includes an allowance; usage past it is metered | Production deployments, Security and quality |
1217| **Usage only** | Nothing up front; every unit is metered | Model tokens, build minutes, storage past the free amount |
1218
1219A card is needed before anything that can cost money starts. Nothing is
1220ever switched on without the workspace choosing it.
1221
1222### Postpaid, with spend limits
1223
1224- **One Stripe customer and one subscription per workspace**, on Flagon,
1225 Inc.'s account. Activations are licensed line items; every usage
1226 dimension is a metered price backed by a Stripe Meter. Stripe invoices
1227 monthly in arrears and charges the card on file; failed payments go
1228 through Stripe's retries and emails, and g1t hears of them by webhook.
1229- **Spend limits instead of prepaid credit.** A workspace sets a monthly
1230 limit overall and per feature (Vercel's spend management). g1t counts
1231 usage as it happens and stops starting new paid work at the limit,
1232 with a warning at 50%, 80% and 100%. Prepaid top-ups go away; promotions
1233 (the free model allowance) become Stripe credit on the customer.
1234- **Usage reaches Stripe from billing alone.** Every service reports
1235 usage to the billing service as it happens (it already records agent
1236 runs and builds); billing batches them into Stripe meter events every
1237 few minutes, idempotently by g1t's own ids, and keeps the ledger g1t's
1238 pages show. Nothing else talks to Stripe.
1239
1240### Scope: workspace, then projects
1241
1242- A feature is turned on for the **workspace** (by an owner, with the
1243 activation if it has one), then allowed for **all projects** or
1244 **selected projects**.
1245- Every **project** can opt out on its own page. A project with nothing
1246 to deploy (no Workers config, no build script, no `index.html`) is
1247 detected, says so on its Deployments page, and never builds or costs
1248 anything.
1249- Agents and workflows are allowed per project the same way, so a
1250 workspace can keep spend to the projects that matter.
1251
1252### Prices: what it costs us, passed through
1253
1254> **2026-10-04, decided:** postpaid with spend limits, as Vercel and
1255> Cloudflare do; no per-seat price, ever ("fuck per-seat pricing").
1256> "If they're barely using them great, but if they're using the shit out
1257> of them that will cost me a ton, so that cost needs to move onto them."
1258
1259**Every Cloudflare cost a workspace causes is metered to it.** Light use
1260fits in a small free allowance; past it, each unit is charged at
1261Cloudflare's price times a margin of at least 1.5, which pays for Stripe
1262(about 3%), shared overhead (the site, the API, D1) and g1t itself.
1263
1264Cloudflare's prices (October 2026), and the cost per unit g1t meters:
1265
1266| What g1t meters | Cloudflare's price | Cost to g1t per unit |
1267| --- | --- | --- |
1268| **Sandbox minute** (agents, checks, merge queue, workflow jobs, deploy builds), standard-1: ½ vCPU, 4 GiB, 8 GB | CPU $0.00002 / vCPU-s while busy; memory $0.0000025 / GiB-s and disk $0.00000007 / GB-s while running | ≤ $0.0012 / minute (CPU counted as busy throughout, since g1t cannot see it per sandbox) |
1269| **App request** (deployments) | Workers for Platforms: $0.30 / million past 20M | $0.30 / million |
1270| **App CPU** | $0.02 / million CPU-ms past 60M | $0.02 / million ms |
1271| **App** (a deployed script) | $0.02 / script-month past 1,000 | $0.02 / app-month |
1272| **Storage** (repositories, artifacts, caches) | Artifacts $0.50 / GB-month (billing starts 2026-10-14); KV $0.50 / GB-month | $0.50 / GB-month |
1273| **Git operation** (clone, fetch, push) | Artifacts $0.15 / 1,000 past 10,000 | $0.15 / 1,000 |
1274| **Model tokens** | The provider's price | As charged |
1275| Container egress, emails, the site's own requests | Small and shared | In the margin |
1276
1277> **2026-10-06, decided:** no per-feature quotas on the plan. "A paying
1278> user should be able to push past the Git operations number, they're
1279> just paying usage on it." One plan, $20 a month per workspace with $10
1280> of usage included; every meter is charged from the first unit at cost +
1281> 20% (builds, app requests and CPU, custom domains), drawn from the $10
1282> first, then up to the spend limit, which is the only thing that stops a
1283> paying workspace (with abuse protection). Projects, previews and apps
1284> are not metered (Workers for Platforms' script pool makes them ~free).
1285> The forge's free amounts are the same for everyone: 1 GB private storage
1286> and 50,000 git operations a month; past them the plan pays and a free
1287> workspace is held (pushes stop, git slowed). The table below is the
1288> earlier proposal; billing's price book and g1t.sh/pricing are current.
1289
1290What a workspace pays:
1291
1292| Meter | Free each month | Then | Margin | For comparison |
1293| --- | --- | --- | --- | --- |
1294| Sandbox minutes | None (2026-10-05: charged from the first second) | Cost + 20%, by the second | 1.2× | GitHub Actions $0.008 / minute (Linux 2-core); Vercel builds $0.0035 / CPU-minute |
1295| App requests | 1 million with Deployments | $0.50 / million | 1.7× | Vercel $0.60 / million invocations |
1296| App CPU | 3 million ms with Deployments | $0.04 / million ms | 2× | Vercel active CPU about $0.036 / million ms |
1297| Apps | 10 with Deployments | $0.05 / app-month | 2.5× | |
1298| Storage | 1 GB | $1.00 / GB-month | 2× | GitHub LFS $0.07 / GB, but repositories are free there |
1299| Git operations | 10,000 | $0.30 / 1,000 | 2× | |
1300| g1t's models | | Cost + 20% | 1.2× | The provider's own price |
1301| Your own model provider | | Only its sandbox minutes (the $0.10 run fee was dropped 2026-10-05) | | |
1302| **Deployments** activation | | $5 / month, with the allowances above | covers Workers for Platforms' $25 / month across workspaces | Vercel Pro $20 per seat |
1303| **Security and quality** activation (built 2026-10-07: price book meter `security_activation`) | | $10 / month; fixes as agent usage | | GitHub Advanced Security $49 per committer |
1304
1305A workspace that uses g1t lightly (a few agent runs, a small site)
1306pays nothing or its activation; a workspace running agents all day pays
1307for the sandboxes and models those agents use, with g1t's margin on
1308each. Nothing in a workspace's bill is subsidised by another's.
1309
1310### Build order
1311
13121. Stripe customer per workspace and card on file (Checkout in setup
1313 mode), webhooks (invoice paid and failed, subscription changes,
1314 payment method changes), the Billing page rebuilt around the four
1315 kinds.
13162. One subscription per workspace with activations as items; Deployments
1317 moves onto it.
13183. Meters for each usage dimension above, fed from billing's ledger:
1319 every sandbox reports how long it ran when it stops (agents, checks,
1320 the queue, workflow jobs and deploy builds alike); deployments report
1321 requests, CPU and apps; repos report storage and git operations. Spend
1322 limits and their warnings; prepaid credit retired.
13234. Per-workspace allow-lists of projects for each feature, and per-project
1324 opt-out; "nothing to deploy" detection.
13255. Turn off FREE_WHILE_BUILDING when the user says so. **Done 2026-10-05.**
1326
1327Shipped by 2026-10-05: sandbox seconds for every sandbox; the price book
1328and its keeper (runs settled to AI Gateway's price every 15 minutes;
1329Container and Workers costs checked against Cloudflare's billable usage
1330and container analytics daily, with a public change log on
1331g1t.sh/pricing); usage limits by trust with automatic payment near the
1332limit; app traffic counted toward limits as it happens; billing accounts,
1333terms and enterprises; free mode off, syntaqx comped.
1334
1335Still to build, in order: Stripe card-on-file without a payment (setup
1336mode) and webhooks; month-end invoices for postpaid usage (and one
1337invoice per enterprise); the subscription with activations as items;
1338storage and git-operation meters; limit warnings by email at 50/80/100%;
1339self-serve enterprise management for enterprise owners.
1340
1341### Accounts, terms and enterprises
1342
1343Every workspace is paid for by a billing account: its own (`ws_<slug>`)
1344or an enterprise's (`ent_…`), which pays for several workspaces with one
1345limit, one set of terms and, once invoices exist, one bill, as GitHub
1346Enterprise does. Terms are standard, comped (nothing charged, usage still
1347recorded at cost, paid features on) or custom (a discount, its own
1348ceiling, an end date). g1t staff manage them in **sudo.g1t.sh**, a
1349separate Worker behind Cloudflare Access that also verifies the Access
1350token itself and allows only listed staff emails; every change is kept
1351with who made it and why.
1352
1353### Limits: stop non-payers, never payers
1354
1355The limit is on usage not yet paid for, counted at cost to g1t or charge,
1356whichever is more: $3 before any live payment, then twice what has been
1357paid ($25 to $1,000), or what staff set. A workspace with a card on file
1358is charged automatically near its limit, which both pays what it owes and
1359raises the limit, so paying users are never stopped. A declined card
1360stops work until paid. The owner's own spend limit always means stop.
1361Test-mode payments never lower exposure or raise trust.
1362
1363### Tax, card fees and free workspaces (built 2026-10-08)
1364
1365> **2026-10-08, decided:** Stripe Tax everywhere ("so I don't fuck up on
1366> taxes"); Stripe's card fee passed to the customer with the 20% markup
1367> kept; one free workspace per person; no invites on free workspaces.
1368
1369- **Stripe Tax on every payment.** `automatic_tax` on every Checkout page
1370 (plan, Security and quality, prepaying, AI credit), every subscription
1371 and every invoice g1t makes (month close, threshold, enterprise), and a
1372 tax calculation and transaction for auto-reload's off-session charge.
1373 Tax code `txcd_10103001` (SaaS, business use), every price
1374 `tax_behavior=exclusive`. Checkout always collects the billing address
1375 and tax ID and saves them on the customer. Prices on g1t are shown
1376 excluding tax. Tax is never revenue: balances and plan payments are
1377 credited without it, it is kept in `tax_and_fees`, shown as its own
1378 statement line, and as **Tax collected** on sudo's Costs. Without an
1379 address g1t does not charge: the owners are asked for one.
1380- **The card fee** (2.9% + $0.30, grossed up) is its own line on every
1381 card payment, the plan's and Security's as a monthly item; never on a
1382 bank transfer or an enterprise's invoice. On by default
1383 (`cost_settings.card_fee`). Not revenue either. Meters stay at cost +
1384 20%; models at the provider's price plus the agent rate.
1385- **One free workspace per person.** Identity asks billing
1386 (`free_workspaces`) before creating one; a second is refused with the
1387 way forward. Those who own several from before keep them.
1388- **A free workspace adds no one**: no members, invites or outside
1389 collaborators until it starts the plan; its members stay; @g1t never
1390 counts. Enforced in identity for every path (site, API, MCP).
1391- Details: docs/BILLING_OPERATIONS.md, *Tax and the card fee*.
1392
1393### Promo codes (planned)
1394
1395Staff credits (promotional, goodwill, refund; `services/billing/src/grants.rs`,
1396docs/BILLING_OPERATIONS.md) are given one workspace at a time. Promo codes
1397give promotional credit in bulk, on redemption, through the same grants:
1398
1399- **Codes.** sudo → Credits & refunds → **New code**: the code (or one
1400 made up), the credit ($ amount), max redemptions, when the code stops
1401 working, how long each redeemed credit lasts (an expiry, as any grant),
1402 and a note. Table `promo_codes` (code, amount, max, redeemed, ends_at,
1403 credit_days, note, created_by, disabled_at) and `promo_redemptions`
1404 (code, workspace, grant id, by, at), unique on (code, workspace).
1405- **Redeeming.** An owner types it on the workspace's Billing page
1406 (`redeem_code`, owners only). One D1 batch checks the code is open, under
1407 its max and not redeemed by the workspace, counts the redemption and
1408 makes the grant (`grant_credit`, kind promotional, the code as its note),
1409 so two redemptions at once never pass the max. Wrong or used-up codes say
1410 so without telling which codes exist; redemptions are rate-limited per
1411 owner.
1412- **Seeing them.** Each code's redemptions, credit given and spent come
1413 from the grants it made, so margin needs nothing new: spent promo credit
1414 is already given away, by kind.
1415- **Not yet built** because it adds an owner-facing form, abuse limits and
1416 a second sudo form; giving credit by workspace covers launch.
1417
1418## Agents and models
1419
1420### Defining an agent
1421
1422An agent is a file (`.g1t/agents/<name>.md`, or in the workspace library):
1423instructions, the harness and model to run, the tools and MCP servers it may
1424use, its sandbox image, permissions and budget. Agents take roles: planner,
1425implementer, reviewer, conflict resolver, documenter, memory consolidator.
1426Each role has a default that a repo can replace.
1427
1428### Where it runs, and on whose model
1429
1430| Option | How it works | Fits |
1431| --- | --- | --- |
1432| Hosted, g1t's model | g1t runs the sandbox and bills usage | Getting started; no keys to manage |
1433| Hosted, your API key | Same sandbox, your Anthropic, OpenAI or Google key | Teams with existing contracts |
1434| Hosted, your endpoint | Any OpenAI-compatible URL: Bedrock, Vertex, Azure, a self-hosted model | Private or fine-tuned models |
1435| Your runner | A g1t runner daemon on your own machines picks up pull requests | Code or models that may not leave your network |
1436| Your own session | Local Claude Code, Cursor or any MCP client joins through `mcp.g1t.sh` | Individuals; subscription plans |
1437
1438Decisions behind this:
1439
1440- **g1t does not build its own agent loop.** It runs existing harnesses
1441 (Claude Code first, through its headless mode) behind a small runner
1442 contract: a container image, an entry command, and session events reported
1443 through the CLI. Other harnesses plug in by meeting the contract.
1444- **All hosted model traffic goes through Cloudflare AI Gateway.** That gives
1445 one place for spend tracking, budgets, rate limits, fallback and logs,
1446 whichever provider or endpoint is behind it.
1447- **Nobody has to pick a model.** A person assigns work to `g1t`, as
1448 they would assign an issue to a colleague, and **Auto** routes each job
1449 to the cheapest model that can do it (see
1450 [Routing for cost](#routing-for-cost) below). A workspace can pin a tier
1451 per kind of work instead. Each request is tagged at the gateway with the
1452 kind of work, the tier, the repository and the pull request, and each
1453 run says which model ran and why. The gateway's own dynamic routes
1454 cannot make the choice yet: they work only on its OpenAI-compatible
1455 endpoint, and the harness speaks Anthropic's.
1456- **Subscriptions stay local.** A Claude subscription cannot be used by a
1457 hosted sandbox; it needs an API key. People on subscriptions use their own
1458 Claude Code session, which is a full participant.
1459- **The workspace pays.** A workspace buys AI credit by card and each
1460 agent run deducts the model at the provider's price plus the agent rate
1461 per million (weighted) tokens; on its own model key, only the agent rate,
1462 counted from the model proxy and the sandbox's own report. The billing service asks
1463 nothing of the others: the runner asks it before starting a sandbox and
1464 is refused when there is no credit, and the sandbox reports what its run
1465 cost with a token only it holds. Where no card processor is configured
1466 nothing is charged and agents stay limited to listed accounts.
1467- **Keys are secrets.** Stored in Cloudflare Secrets Store, injected into the
1468 sandbox for one pull request, never shown again.
1469
1470### Seeing a pull request through
1471
1472Assigning an issue is the only thing a person does until there is something
1473to merge. A pull request made by g1t goes through checks, a review
1474by another agent, revision when either finds something, and catching up
1475when `main` moves, without anyone pressing a button. It ends as ready to
1476merge, or as "needs you" with the reason: the checks still fail after two
1477revisions, a review could not be written, or a conflict could not be
1478resolved.
1479
1480The work service decides the next step from the pull request's state and
1481claims it in one statement, so a step is taken once. The runner asks on
1482every event that could change the answer (ready, pushed, checks finished,
1483review finished, `main` moved), and on a five-minute sweep for anything
1484missed, and carries the step out in a sandbox.
1485
1486A pull request does not have to be up to date with `main` to merge,
1487unless the repository's settings require it, as on GitHub. Merging one that
1488is behind brings it up to date first (a clean merge needs no model; an
1489agent resolves a conflict) and lands it when that push arrives. With the
1490requirement on, catching up is a step of its own and the checks run again
1491on the result.
1492
1493Each repository sets its own rules, on one settings page: whether its
1494default branch takes pushes at all, how many approvals a merge needs and
1495whether an agent's counts, whether failed checks can be overridden, whether
1496a second agent reviews, and how often an agent is sent back before a person
1497is asked. A pull request g1t opens follows the same rules as anyone's.
1498Pushes to a protected branch are refused in the git front end, with the
1499reason shown by git beside the branch.
1500
1501Merging is a person's decision unless the repository says otherwise. With
1502"merge automatically when ready" turned on in its settings, a ready pull
1503request lands by itself, attributed to `g1t`. That is the whole path from
1504an assigned issue to a commit on `main` with nobody in between. Required
1505human approval per path, and risk tiers, are still to come.
1506
1507### Routing for cost
1508
1509*Built (runner `route` in `services/runner/src/model-env.ts`).* The goal
1510is cost per merged change, not cost per request: a cheap attempt that
1511fails and is retried on the same model costs more than one that finishes.
1512
1513- **Tiers and catalogue.** `small` (Claude Haiku 5.5 since 2026-10-08,
1514 $0.10/$0.50 per million input/output up to 100k-token prompts, five
1515 times that above; it was Haiku 4.5 at $1/$5), `large` (Claude Sonnet 5.5, $2/$10) and `frontier`
1516 (Claude Opus 5.5, $4/$20). Models, names and list prices are data,
1517 never code: since 2026-10-08 billing's model catalogue
1518 (`gateway_models`, one row per model g1t can use) and staff's defaults
1519 in sudo, **Agents & models** (`model_defaults`: each tier's model, the
1520 harness's background model, the AI Gateway's first Claude, each job's
1521 starting tier and effort), read by the runner once a minute over
1522 `AGENT_ROUTING`, which is only the fallback when billing cannot be read.
1523 Catalogue prices are for estimates only; runs are charged what AI
1524 Gateway priced them at.
1525- **Keeping up with new models (built 2026-10-08).** The models service
1526 lists Anthropic's models (through the AI Gateway) and Workers AI's daily
1527 and on demand; a new id lands in the catalogue as `new`, priced from a
1528 maintained table of Anthropic's list prices or Workers AI's listing, or
1529 unpriced, and staff are emailed. Nothing routes to it, offers it or
1530 charges for it until staff approve it with its prices. A model a provider
1531 stops listing is `deprecated`; routing never sends work to a deprecated
1532 or retired model, falling back to the next model of the tier and saying
1533 so on the run. Customers keep Auto: the catalogue is staff's. See
1534 [BILLING_OPERATIONS.md](BILLING_OPERATIONS.md#the-model-catalogue).
1535- **Starting tier by job.** Catch-up, answering a question, and reviews of
1536 at most 10 files and 200 lines touching no sensitive path: small.
1537 Plans: small at high effort (Haiku 5.5 takes an effort level).
1538 Changes, revisions and other reviews: large. Reviews over 60 files
1539 or 3,000 lines: frontier. Labels: `architecture` frontier, `security` off
1540 small, `docs`/`documentation`/`typo` let changes and answers start small.
1541- **Escalation.** A failed (or guardrail-stopped) attempt at the same work
1542 goes one tier up; two in a row, frontier; a revision counts its rounds;
1543 a change left at low confidence sends the next attempt up.
1544- **Learning, per repository.** From the last 20 runs of the same kind:
1545 one tier down when the cheaper tier finished at least 90% of at least 5
1546 (never for sensitive or labelled work, never on a retry); one tier up
1547 when this tier failed at least half of at least 5. No new tables: it
1548 reads work's `agent_runs` (model, status, confidence).
1549- **Explained.** Every run's first step and session note is one line:
1550 *Used a fast model (Claude Haiku 5.5): small change, 3 files and 80
1551 lines.* Effort per kind of job (`effort` in `AGENT_ROUTING`: plan high,
1552 answer medium, update low) is sent as `CLAUDE_CODE_EFFORT_LEVEL` on
1553 g1t's tiers (never on a model the catalogue says takes none) and named
1554 in that line, with the catalogue's name for the model.
1555- **Chosen instead.** `model_routes` rows to g1t's models name `small`,
1556 `large` or `frontier`, or nothing for Auto (Integrations → Models).
1557 A workspace's own Anthropic key with no model named is routed by Auto
1558 too.
1559- **Measured.** `scripts/ops/routing-savings.mjs` replays tasks through
1560 the router offline, priced from the catalogue, against routing before
1561 Auto and against the frontier model for everything, net of failed
1562 attempts, with cost per merged change; `--live` reads billing's runs and
1563 counted tokens. On the bundled sample (13 tasks, assumed failures): Auto
1564 costs 7% less than the frontier model for everything and about 7% more
1565 per run than routing before it, but half as much per merged change,
1566 because it finishes the hard tasks the old routing gave up on. At
1567 current prices Opus 5.5 and Sonnet 5.5 cost the same per cache read, and
1568 cache reads are most of an agent run's tokens, so moving off the
1569 frontier model saves less than its list price suggests; the fast tier
1570 and fewer failed attempts are where the money is. Run `--live` monthly
1571 and after any routing change.
1572- **A cheaper route for the simplest jobs (designed, off).** A fourth tier
1573 on Workers AI through AI Gateway (an open model, billed on Cloudflare's
1574 invoice) for classification-sized jobs: commit messages, triage,
1575 summaries. Behind the same router as a tier with its own catalogue entry
1576 and `tasks` rules, off by default. It needs the proxy to translate the
1577 harness's Anthropic requests to the gateway's OpenAI-compatible
1578 endpoint (it already does for workspaces' own OpenAI-shaped providers)
1579 and a quality bar from the savings harness before any job moves to it.
1580
1581### Choosing the right agent automatically
1582
1583Because several agents can work on the same issue, every issue with more
1584than one pull request is an evaluation on real work. g1t records, per repo and per kind of issue, each
1585agent's win rate, cost and time. That produces a leaderboard, and a routing
1586policy: send each new issue to the agent that wins that kind most often,
1587start with the cheapest that is good enough, and escalate to a stronger one
1588when checks fail.
1589
1590## Talking: the inbox and channels
1591
1592Not a discussions forum. People and agents need one place to talk in real
1593time, and an app that feels like one on desktop and phone.
1594
1595**The inbox comes first.** Everything that needs a person or that they
1596follow, from people and agents: review requests, agent questions and
1597handoffs, failures, mentions, deploys. Read and unread, saved, done,
1598snoozed; ranked so what an agent is blocked on comes first; email digests
1599and push. It is the delivery layer chat needs too (who is told what, read
1600state, push), so building it first makes channels cheap.
1601
1602*Built:* the events service keeps it (`services/events/src/inbox.rs` and
1603`subscriptions.rs`, migrations `0005_inbox` and `0006_inbox_threads` on the
1604`g1t-events` database), writing items as events arrive from the bus; work's
1605`inbox_subject` says what each event names. Each person has one **thread**
1606per issue, pull request, workflow on a branch or deployment: new activity
1607brings it back unread with a count and its last 10 activities, and while it
1608is unread its most urgent severity is kept. Each item has a **reason**
1609(`agent`, `review_requested`, `assign`, `mention`, `ci_activity`,
1610`security_alert`, `state_change`, `author`, `comment`, `manual`,
1611`subscribed`). Who is told: `agent.asked` and `pull.stalled` (needs you,
1612closed again by `pull.resumed` and the like), `pull.review_requested`
1613(needs you, closed by `pull.review_request_removed`),
1614`issue.assigned`/`pull.assigned`, failed checks and workflows,
1615`deployment.failed` and a recovering `deployment.succeeded`, g1t's reviews
1616and finished changes, closes, reopens and merges to everyone subscribed,
1617and comments to the people mentioned and everyone subscribed. Never the
1618actor, never g1t. **Subscriptions**: authors, assignees and reviewers are
1619subscribed without a row; commenting or being mentioned subscribes; anyone
1620can subscribe, unsubscribe (still told of what is asked of them) or ignore.
1621**Watching** a repository: participating (the default), all, ignore, or
1622custom (issues, pulls, deployments, security); whoever creates a repository
1623watches it at their default, all activity unless they change it.
1624**Settings**: which reasons are also emailed (agent, review_requested and
1625mention by default) and the default watch for new repositories; email goes
1626through identity's `notify_by_email`, to a confirmed address only while the
1627person can still read the repository. **REST and MCP**: 14 operations under
1628`/notifications`, `/repos/:owner/:name/subscription` and
1629`/user/subscriptions` (scopes `notifications:read` and
1630`notifications:write`, in the Agent preset), and the `notifications` MCP
1631tool; never usable by g1t's own tokens. On the site: a bell in the top bar
1632opening a sheet with tabs (All, Needs you, Errors, Success, Info), Done,
1633Save, Snooze and Mark all read; `/inbox` with Saved, Done and a reason
1634filter; reasons and update counts on each card; a Notifications box on
1635issue and pull request pages; a Watch menu in the repository header;
1636Settings → Notifications; a Needs you card on mission control. Agent sits
1637beside the bell, disabled. Still to come: security alerts (the security
1638service publishes no event yet), email digests and push, Agent, and
1639channels.
1640
1641**Channels** (working name): workspace channels, direct messages and
1642threads, live.
1643
1644- Each channel is a Durable Object holding its WebSocket connections with
1645 hibernation, so idle channels cost nothing; history in D1, files in R2.
1646- Agents are members. `@g1t` in a channel starts work, answers, or
1647 posts a summary; agents post their questions and handoffs where people
1648 already are. A thread becomes an issue or an outcome in one action, and
1649 the agent's progress streams into that thread.
1650- Tied to the work: issues, pull requests, runs and deploys each have a
1651 thread; links unfurl into live cards (checks, agent step, preview).
1652 What a channel settles can become workspace memory, with its source.
1653- Apps: an installable PWA first (desktop and mobile, offline shell, Web
1654 Push), then native shells on the same API: Tauri for desktop (tray,
1655 deep links), React Native for iOS and Android (background
1656 notifications).
1657
1658GitHub-style Discussions are not planned: channels and threads on the
1659work replace them.
1660
1661## What GitHub ships today, and where g1t differs
1662
1663GitHub's Agent HQ and Copilot app give each agent session its own git
1664worktree and branch, list sessions in a mission-control view grouped by
1665project, and let a task be assigned to several agents so their output can be
1666compared. Underneath, the unit of work is still a branch and a pull request.
1667
1668| | GitHub | g1t |
1669| --- | --- | --- |
1670| Where a session works | A worktree on one developer's machine, or a cloud sandbox | A server-side fork that any agent on any machine can join and anyone can open |
1671| Agent context | Lives in the app's session view | Stored with the repository and linked from each commit (why-blame) |
1672| Several agents on one task | Separate pull requests to compare by hand | One issue holding every pull request made for it, compared side by side, with the merged one recorded on the issue |
1673| Collisions between agents | Found as merge conflicts at the end | Flagged during the work (overlap radar) |
1674| Landing changes | One pull request at a time | A merge queue that lands the chosen one and closes the rest as superseded |
1675| Which agents | Those offered through a Copilot subscription | Any MCP client, plus hosted agents |
1676
1677## How agents connect
1678
16791. **Bring your own agent.** A remote MCP server at `mcp.g1t.sh` lets Claude
1680 Code (or any MCP client) list issues, claim one, get a clone URL and
1681 token, report progress and submit. Adding it is one command; sign-in is a
1682 browser OAuth flow with no token to paste. The `g1t` CLI installs Claude
1683 Code hooks that upload the session transcript as the agent works.
16842. **g1t's agent.** Assign an issue to g1t, or many issues at
1685 once, each to an agent of its own. g1t starts a sandbox for each
1686 (Cloudflare Containers), running a coding agent headless against its
1687 own pull request and fork.
16883. **API and CLI.** Everything above is available at `api.g1t.sh` and
1689 through `g1t`.
1690
1691## Public surfaces
1692
1693| Host | What it serves |
1694| --- | --- |
1695| `g1t.sh` | The site, git over HTTPS, git over SSH |
1696| `api.g1t.sh` | REST API, with no version in its paths, with a published OpenAPI document, cursor pagination, rate-limit headers, idempotency keys on writes, server-sent events for live pull request state, and signed webhooks |
1697| `mcp.g1t.sh` | Remote MCP server over streamable HTTP |
1698
1699g1t is its own OAuth 2.1 authorization server: authorization code with PKCE,
1700dynamic client registration that stores nothing (a client id encodes its
1701own registration, so the open endpoint cannot be used to fill a database),
1702discovery metadata and rotating refresh tokens. Still to come: scopes
1703per resource (`repo:read`, `repo:write`, `issue:write`, `pull:write`).
1704MCP clients, the CLI (device flow) and third-party apps all use it. Access
1705tokens and SSH keys remain for git itself.
1706
1707### Workspace aliases (internal, built 2026-10-07)
1708
1709`g1t` is the product; `flagon-io` is Flagon, Inc., the organization that
1710builds it. So nobody mistakes one for the other, `g1t.sh/g1t` leads to
1711`g1t.sh/flagon-io`. That is a workspace alias: a name g1t's staff point at
1712a workspace, kept in identity's `workspace_aliases` (migration 0029, which
1713seeds `g1t`) by the workspace's id, so it follows renames. It is not a
1714customer feature and is not documented for users; staff add and remove
1715aliases on sudo's Aliases page, with a reason, in sudo's audit log. We may
1716give other companies one for a trading name the same way.
1717
1718An alias is resolved wherever an old slug is (identity's `resolve_slug`),
1719so it costs only the not-found path: site pages 301 to the same page under
1720the workspace, the API and MCP run the call again under its slug, package
1721registries 301, and git over HTTPS is answered in place
1722(`resolve_alias`), because pushes do not follow redirects. An alias is
1723never a route, a username or a workspace's slug, and nobody can register
1724it while it exists. `@g1t` stays g1t's agent: mentions link to how the
1725agent works, never to `/g1t`.
1726
1727## Architecture
1728
1729| Component | Language | Runs on | Responsibility |
1730| --- | --- | --- | --- |
1731| `crates/contracts`, `packages/contracts` | Rust, TypeScript | — | The interface of every service, the event catalogue, shared types. Services and clients depend on this, never on each other's code. |
1732| `services/identity` | Rust | Worker + D1 | Accounts, workspaces and memberships, sessions, SSH keys, access tokens, device sign-in, OAuth codes and grants |
1733| `services/repos` | Rust | Worker + D1 + Artifacts | Repository registry, contents, forks, diffs, landing, git over HTTPS. Storage sits behind a `GitStore` port with an Artifacts adapter. |
1734| `services/work` | Rust | Worker + D1 | Issues, pull requests, comments, sessions; later a Durable Object per repo for the landing queue and live state |
1735| `services/billing` | Rust | Worker + D1 + Stripe | Each workspace's agent credit: payments, the ledger of every run, and the gate on starting one |
1736| `services/events` | Rust | Worker + Queues + D1 | The event bus: durable log, and one queue per subscribing service |
1737| `services/runner`, `crates/runner` | TypeScript, Rust | Worker + Containers | Starts a sandbox per g1t run; the program inside runs the agent harness and reports through the public API |
1738| `services/og` | TypeScript | Worker + Cache API | Social cards at `og.g1t.sh`: one PNG per page of the site and the docs (satori and resvg), looked up as an anonymous visitor, so nothing private appears on one |
1739| `apps/web` | TypeScript | Worker | Server-rendered site. Holds no data; calls services over RPC. |
1740| `apps/docs` | TypeScript | Worker (static) | Documentation and the API explorer |
1741| `apps/api` | Rust | Worker | REST API (`api.g1t.sh`), MCP server (`mcp.g1t.sh`) and OpenAPI document, all generated from one list of operations; the OAuth endpoints |
1742| `crates/sshd` | Rust | Container | Git over SSH, bridged to Artifacts |
1743| `crates/merged` | Rust | Container | Trial merges, conflict matrix, landing merges (needs real git; the Artifacts binding is read-only) |
1744| `crates/core` | Rust | native and WASM | pkt-line, packfile and diff code shared by the above and by the Worker |
1745| `crates/g1t` | Rust | user's machine | CLI: auth, SSH proxy, Claude Code hooks, issues and pull requests |
1746
1747Storage: Artifacts for repositories (one fork per pull request), D1 for accounts
1748and metadata, R2 for session transcripts and logs, Durable Object SQLite for
1749per-repo coordination state.
1750
1751How the services fit together:
1752
1753- **Each service is its own Worker with its own database.** It deploys,
1754 scales and fails on its own. Callers reach it through a typed RPC binding
1755 to the interface in `packages/contracts`.
1756- **Expected failures are values.** Every call returns a `Result`, so "not
1757 found" or "forbidden" crosses a service boundary as data.
1758- **Side effects travel as events.** A service publishes what happened
1759 (`git.push`, `issue.opened`, `pull.merged`, …) to the bus and does not
1760 call other services to react. Each subscriber consumes from its own queue.
1761 Timelines, webhooks and automations read the same stream, which is what
1762 lets something like GitHub Actions be built on top.
1763- **Every read takes the viewer.** Authorization is decided inside the
1764 service that owns the data, not by its callers.
1765
1766The Workers runtime scales request handling on its own, so the edge layer
1767stays in TypeScript. Rust is used where there is real computation or a real
1768protocol to implement.
1769
1770## Languages
1771
1772The site is TypeScript. Everything behind it is Rust, compiled to
1773WebAssembly for Workers and natively for containers and the CLI. Identity, repos, work, events and the API are all Rust. The one exception
1774is the Worker that starts sandboxes, because Cloudflare's Containers
1775library is TypeScript. Rust services speak a
1776small JSON protocol over service bindings (`POST /rpc/<method>`), with the
1777types in `crates/contracts`.
1778
1779## Identifiers
1780
1781Every id is a [TypeID](https://github.com/jetify-com/typeid): a prefix naming
1782the kind of thing, then a UUIDv7 in lowercase base32, such as
1783`pr_01jb2k7x9hfq0b3zj0f5s2m8ra`.
1784
1785- The prefix makes an id self-describing and stops ids of different kinds
1786 being mixed up.
1787- Ids sort by creation time as plain strings. In SQLite (D1 and Durable
1788 Objects) that keeps inserts at the end of the primary-key index instead of
1789 scattering them, and gives time-ordered paging for free.
1790- The suffix decodes to a standard UUIDv7 for any system that wants one.
1791- Ids are made by the service that creates the record, not by the database,
1792 so they work across services and can be assigned before a write.
1793
1794## Events at scale, and audit
1795
1796The current event log is a single D1 database. That is fine for a
1797prototype and wrong for the target: D1 is one writer and 10 GB. The design
1798for volume splits storage by how the data is read.
1799
1800| Tier | Store | Holds | Read by |
1801| --- | --- | --- | --- |
1802| Hot | A Durable Object per repository, with SQLite | Recent events for that repo | Timelines, live pages over WebSocket |
1803| Complete | Cloudflare Pipelines into R2 as Apache Iceberg | Every event, forever, partitioned by day and workspace | Analytics, standups, "ask", export |
1804| Audit | The same R2 store, under object lock | Who did what, from where, with which credential | Compliance, investigation |
1805
1806- **No single hot database.** Each repository's recent events live with that
1807 repository, so load spreads across as many objects as there are repos.
1808- **The complete record is files, not rows.** Iceberg on R2 has no practical
1809 size limit and is queried with SQL.
1810- **Audit is a property of every event.** The envelope carries the actor
1811 (person, agent, token or system), the credential used, the request id and
1812 the source address. Audit entries for a workspace are hash-chained, so a
1813 removed or altered entry is detectable, and are written under a retention
1814 lock.
1815- **Delivery is at least once.** Consumers are idempotent on the event id.
1816
1817## Accounts and forge basics
1818
1819- Registration with email verification, sign-in, forgot password (Cloudflare
1820 Email Sending), Turnstile on public forms.
1821- GitHub sign-in, SSH keys, access tokens, active sessions.
1822- Profiles, public and private repositories, repository search (D1 full-text).
1823- Rendered README, syntax highlighting, commit history, diffs.
1824- Transferring a repository between workspaces (by id: its git store key
1825 never moves; every service follows `repo.transferred`; old paths redirect
1826 until reused) and deleting an empty, settled workspace (its slug is
1827 tombstoned, never reissued except to the person whose username it is).
1828- Access: five repository roles (Read, Triage, Write, Maintain, Admin;
1829 the capability table follows GitHub's repository roles, 2026-10-08:
1830 branch protection and rulesets are Admin, labels and milestones are made
1831 with Write and applied with Triage, security alerts are Write), a
1832 workspace base permission (Read for new workspaces), the creator of a
1833 repository given Admin on it, outside collaborators and invitations.
1834 Membership as GitHub's organizations have it (2026-10-08): owners and
1835 members, promote and demote, transfer ownership, leave, a last-owner
1836 guard; billing manager and security manager on top of member; member
1837 privileges (who creates public and private repositories, whether
1838 repository admins change visibility, delete and transfer, and invite
1839 outside collaborators); two-factor authentication (TOTP and recovery
1840 codes) and a workspace policy that requires it, holding non-compliant
1841 people out until they turn it on. Every membership change, token, SSH
1842 key, OAuth grant and two-factor change is in the audit log. Teams are built on it (2026-10-07): visible
1843 or secret, nested up to 8 levels (child teams inherit their parents'
1844 roles), run by maintainers and owners. A team's role on a repository is a
1845 `repo_grants` row whose principal is the team, which identity resolves
1846 into the same `RepoGrant`s on each person, so `access::can` needs nothing
1847 new: the highest role wins. `@workspace/team` mentions tell the team's
1848 people; a team asked to review either asks everyone or picks people by
1849 round robin or load balance.
1850- CODEOWNERS, read in both conventions (single-section, and sections with
1851 approval counts, optional sections and default owners) from the first of
1852 `.g1t/`, `.github/`, the root, `docs/` and `.gitlab/`. Owners are asked to
1853 review, the `g1t / codeowners` status lints a changed file, and branch
1854 protection's "Require review from code owners" holds merges, for people,
1855 agents and the queue alike, until each owning rule is approved.
1856

1876## Running g1t yourself
1877
1878g1t.sh runs on Cloudflare, and that does not change. The core is MIT and
1879must also run on anyone's own machine with `docker compose up`. A free
1880core people can self-host is what makes paid hosting worth trusting.
1881Self-hosting never makes hosted worse: hosted code paths keep their
1882behaviour, and a self-hosted adapter sits beside the hosted one. The
1883inventory of every Cloudflare dependency, the design and the risks are in
1884[SELF_HOSTING.md](SELF_HOSTING.md).
1885
1886The approach: the Workers stay Workers, and self-hosted they run in
1887workerd, the open-source Workers runtime. D1, KV and Queues are SQLite on a
1888volume, with the same migrations. Cloudflare-only bindings are replaced
1889by stand-ins:
1890
1891- Artifacts becomes bare repositories served by `git http-backend`;
1892- Email Sending becomes SMTP, through Mailpit;
1893- services that are off answer "off" instead of failing.
1894
1895| Phase | Scope | Estimate |
1896| --- | --- | --- |
1897| 1. Core forge | Done: `deploy/self-host/` (compose, git store, binding stand-ins, smoke test) and the "Run g1t yourself" guide. Left: the API on its own port, `PUBLIC_URL` in place of hard-coded hosts, cron, pull requests in the smoke test, CI that runs it. | 1–1.5 weeks left |
1898| 2. Agents | Docker sandboxes with the same runner image, an egress allow-list proxy for guardrails, `g1t.toml`, a launcher in place of `wrangler dev` | 2–3 weeks |
1899| 3. Search, context, deployments | sqlite-vec plus an OpenAI-compatible embedder; an app host on workerd; Caddy for app and custom domains; SSH | 3–4 weeks |
1900| 4. Parity and upgrades | Code-level ports in `g1t_kit` and `@g1t/platform`, sudo without Access, online backups, released images, an upgrade test in CI | 3–4 weeks |
1901
1902## The submission
1903
1904- **g1t is built on g1t.** This repository is hosted on g1t.sh, its features
1905 are opened as issues and built by racing agents, and it deploys from
1906 Artifacts through Workers Builds. The history is the proof.
1907- **The demo follows one story.** A brief becomes a project; twelve issues
1908 fan out to dozens of agents; agents notice each other, hand off, and
1909 resolve a conflict; reviewers triage; the queue lands everything on
1910 `main`; why-blame explains a line; the portfolio shows where it all
1911 stands. Then the same thing at a thousand agents.
1912- **Judges can try it in a minute.** Open registration on g1t.sh, one-click
1913 import of a GitHub repo, one command to connect Claude Code, a seeded demo
1914 workspace, and a single deploy command for running their own copy.
1915- **The formats are open.** The commit trailers, session format and runner
1916 contract are published so other tools can interoperate.
1917
1918## Build order
1919
1920What is left is ordered by how much it shows the point above, not by forge
1921parity. Forge basics are done well enough; each item below should make the
1922demo's story stronger.
1923
1924Done from this list: the outcome page (a plan's issues as a live graph with
1925cost and a feed of what happened), coordination you can see (agents' issues
1926and comments stand out in the feed; agents hold g1t's tools through a token
1927scoped to one repository), steering a running agent (messages delivered
1928between steps, and at the end), and recording sessions from anyone's own
1929Claude Code (`curl -fsSL https://g1t.sh/install/claude.sh | sh`). Integrations are
1930in: a workspace's own model provider (Anthropic or any Anthropic-compatible
1931endpoint, reached through a model proxy so no sandbox holds a key; its
1932runs pay only their sandbox time), alerts from Sentry, Datadog and signed webhooks
1933that open one issue per problem and can start an agent, and Jira and Linear
1934tickets that agents read, people import, and that hear back. Racing a
1935set number of agents on one issue is dropped: choosing how many agents to
1936use is not something people should have to do.
1937
19381. ~~**Handoffs and questions between agents** as states on the outcome
1939 page.~~ Done: questions and handoffs show as waiting, read, answered,
1940 taken on or declined; since 2026-10-03 an agent asked while it is not at
1941 work is woken to answer, where before the question waited forever.
19422. **Upkeep agents** (above): dependency updates, secret scanning,
1943 vulnerability alerts, code scanning, the security page. No new
1944 infrastructure.
19453. **Deployments on `g1t.page`** (above): previews per pull request,
1946 production on merge, the reviewer agent checking the preview.
19474. **The large run, building 2 and 3.** About 20–30 issues on g1t itself,
1948 built by agents and landed through the queue, for the video: g1t built
1949 on g1t.
19505. **Polish for judges trying it in a minute:** a seeded demo workspace, the
1951 empty states, and the first-run path from sign-up to an outcome landing.
1952
1953Earlier items still open, after those:
1954
19551. Deleting a branch once its pull request merges; risk tiers. (Approval
1956 rules per path are in, as CODEOWNERS.)
19572. Event storage per the design above: per-repo hot log, Iceberg on R2,
1958 hash-chained audit.
19593. CLI with Claude Code hooks to record sessions automatically.
19604. Reviewing and catching up automatically, by policy; required reviews;
1961 risk tiers.
19625. Compare view, proof bundles; handoff between agents.
19636. Projects, mission control, steering; why-blame, digest, timeline.
19647. Context hub, portfolio; automations and integrations (Sentry first).
19658. SSH; bot protection; own keys, endpoints and runners.
19669. Large run (100+ agents across many issues), hardening, demo.
196710. Passkeys (WebAuthn) as a second factor and for signing in: feasible on
1968 Workers (P-256 and RS256 verification in Rust, or WebCrypto), next
1969 after TOTP. Then fine-grained tokens, deploy keys and package access.
1970
1971Later: code search, mirroring to GitHub, SSH
1972on port 22 without the CLI proxy (needs the Workers inbound TCP private
1973beta).
