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 repos as markdown, shown in a Docs view: rendered pages, edited in the
281 browser like a document, with inline comments. "Suggest a change" is an
282 pull request and "publish" is merge, without git vocabulary.
283- **Document issues.** "Write the onboarding guide for the billing API" is
284 an issue. Its Definition of done is a checklist judged by a reviewer agent
285 instead of a workflow. Agents draft and revise; people comment and approve.
286- **Templates.** Product brief, RFC, decision record. A filled-in template is
287 a brief the planner can turn into a project.
288- **Explain.** Ask about any repo, project or change in plain language and
289 get an answer with links to the code and sessions behind it.
290- **Living documentation.** g1t generates "how this works" pages from the
291 code and keeps them current. When a merged change contradicts a document,
292 an issue opens to update it.
293- **See it, don't read it.** Every pull request on a deployable repo gets a
294 preview URL (Workers Builds from the pull request's fork), so an approver clicks
295 through the result instead of reading a diff. Changes are also summarised
296 in plain language.
297- **Roles.** A person can plan and approve work without ever cloning a
298 repo. The roles that were sketched here map onto the five repository
299 roles that are built (see "Access" under what is built): a viewer is
300 Read, a commenter is Read (anyone with Read opens issues and comments),
301 a planner is Triage (labels, milestones, assigning, closing) or Write
302 where planning spends compute, and an approver is Write (reviews count
303 and merges). Workspace-wide, a member may also be a billing manager or a
304 security manager.
305
306## The macro view
307
308The hierarchy above a single repo:
309
310| Level | What it is |
311| --- | --- |
312| **Workspace** | A company or team: its people, repos, agents, budget and policies. |
313| **Initiative** | A business outcome with an owner and measurable results, e.g. "move billing to usage-based pricing". Spans any number of repos. |
314| **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. |
315| **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. |
316
317How it feeds up, and what is built:
318
319- **A workspace is the unit everything belongs to.** Repositories, people,
320 access tokens, and later projects, budgets and policies are the
321 workspace's, never a person's. An account owns nothing; its first step
322 after confirming its email is creating a workspace, and the site sends it
323 there from wherever it was going.
324- **One namespace.** Usernames and workspaces share one set of names, as on
325 Docker Hub and npm. A username is reserved for its owner's workspace, so
326 `g1t.sh/<name>` never means two things.
327- **The workspace page is the roll-up.** `g1t.sh/<workspace>` shows its
328 repositories with their open issues and pull requests, and the pull
329 requests in progress across all of them. Projects and initiatives will
330 roll up to the same page. Its own pages live under `/<workspace>/-/`
331 (people, access tokens, settings), which no repository can be named.
332- **Workspace access tokens instead of service accounts.** A workspace has
333 tokens of its own, in the same table and code path as personal ones. One
334 acts as the workspace, with a member's rights in that workspace only (the
335 Write role on its repositories; Admin only when an owner ticks it at
336 creation, `access_tokens.admin`, identity/0034), records who made it and
337 when it was last used, and keeps working when that person leaves. CI,
338 integrations and automations use these. Until 2026-10-08 the code gave
339 them Admin on every repository, which the security audit found let any
340 workspace token manage webhooks; code, this plan and the docs now agree.
341
342### Portfolio
343
344One page answers "where is the business" across every initiative:
345
346- **Health** per initiative: on track, at risk, or blocked, derived from
347 facts (checks passing, issues stalled, questions waiting on a person),
348 not self-reported.
349- **Progress** as measurable results: required checks passing, issues
350 merged out of planned, and the trend since the start.
351- **Forecast** from actual throughput: at the current rate, when the
352 remaining issues land.
353- **Spend** in tokens and dollars against a budget, per initiative.
354- **Waiting on people**: every decision or approval a person owes, by name.
355- **Roadmap**: initiatives laid out as now, next, later, with optional
356 time-boxed cycles for teams that work in sprints.
357
358### Status without asking
359
360- **Standup.** An agent writes a daily report per initiative and one for the
361 whole workspace: what merged, what changed direction, what is at risk and
362 why, what needs a person. Delivered by email or webhook.
363- **Ask.** A question box over the full event log and all sessions: "what
364 happened on the billing migration since Monday?" answers with links to the
365 sessions and commits behind each claim.
366
367### Long-running agents
368
369Work that runs for days needs supervision that does not depend on someone
370watching.
371
372- **Checkpoints.** A long pull request reports milestones against its issue, so
373 progress is visible before anything merges.
374- **Stall and drift detection.** A pull request with no meaningful progress, or
375 whose changes have wandered away from its issue, is flagged and can be
376 stopped or re-briefed automatically.
377- **Budgets.** Hard limits on spend and time per pull request, project and
378 initiative.
379
380### Context hub
381
382Agents working across repos and days need context that outlives any one
383session and reaches beyond the code. The context hub is one place an agent
384asks, whatever the source.
385
386| Source | What it holds | How it gets there |
387| --- | --- | --- |
388| **Memory** | Decisions, conventions, gotchas, facts about systems | Written by agents and people in g1t |
389| **Code and sessions** | The repos, and the reasoning behind every change | Already in g1t |
390| **Connected sources** | Jira and Linear tickets, Notion and Confluence pages, Google Drive documents, Slack threads, Sentry issues | Connectors, authorised per workspace |
391
392How it behaves:
393
394- **One search.** An agent asks a question and gets ranked results across
395 all sources, each labelled with where it came from, who wrote it, and how
396 fresh it is.
397- **Connected sources stay where they are.** g1t indexes them for search and
398 fetches the current version when an agent opens one. The external system
399 remains the source of truth, and a link placed on an issue ("see
400 JIRA-482", a Notion URL) is pulled into the agent's starting context.
401- **Permissions carry over.** A connector only exposes what the connecting
402 account can see, and a workspace admin chooses which spaces, projects or
403 channels are included.
404- **External content is untrusted.** A ticket or page can contain text meant
405 to manipulate an agent. It is marked as reference material, never treated
406 as instructions.
407- **Documentation is separate.** Context is what agents know; documentation
408 is what people read, and it is generated from context and code.
409
410Memory is the part of the hub that g1t owns and agents write to:
411
412- **Memory is written freely.** Any agent or person adds an entry with one
413 call: a decision, a convention, a gotcha, a fact about a system. No review
414 gate. Each entry records who wrote it, from which session, and when.
415- **It is still a repository.** Each workspace has a memory repo in
416 Artifacts, so every write is a commit: versioned, attributable, and
417 revertible.
418- **It is kept healthy by an agent.** A consolidation agent merges
419 duplicates, retires entries that newer ones contradict, and flags
420 conflicts it cannot settle. People can pin an entry (agents may not change
421 it), correct it, or retract it.
422- **Agents read it.** Every session starts with the context relevant to its
423 issue, found by search, and can query more through MCP.
424- **Updates are events.** A memory write or a change in a connected source
425 is an event, so "when context changes, update the affected docs" is an
426 automation, on by default.
427- **It is scoped inside the workspace.** Some context applies to the whole
428 workspace, some to one initiative, project or repo, so an agent gets what
429 applies to its work.
430- **It never crosses workspaces.** A workspace is the isolation boundary: its
431 context, sessions and private repos are invisible to every other
432 workspace, and an agent's token is bound to one workspace.
433
434## Working in g1t
435
436- **Mission control.** The signed-in home page: every running session, every
437 issue waiting on a decision, and what merged, across all repos.
438- **Outcomes.** Group issues across repos toward one result and track how
439 many are open, racing, or merged. (What [Projects](#projects) means is
440 below.)
441- **Steering.** Send a message to a running pull request, or to all pull requests on an
442 issue at once, without stopping them.
443- **Automations.** Rules that start work without a person (next section).
444
445## Automations and integrations
446
447> **2026-10-03:** g1t's own `.g1t/automations` format was built and then set
448> aside at the user's request ("let's just copy GitHub Actions on that for the
449> time being"). Automation on g1t is GitHub Actions workflows in
450> `.g1t/workflows/`; the format below is kept for later.
451
452An automation is **when** an event happens, **if** conditions hold, **do**
453something. They are defined as files in the repo (`.g1t/automations/`), the
454way GitHub Actions workflows are, and can also be built in the UI.
455
456### Events that can trigger one
457
458| Source | Examples |
459| --- | --- |
460| Git | push, merge, check failed, `main` moved |
461| g1t | issue opened, pull request stalled, context updated, handoff declined, budget reached |
462| Time | cron schedule |
463| Integrations | Sentry issue, PagerDuty incident, Linear or Jira ticket, Slack message or mention, GitHub issue, Stripe event |
464| Anything else | a signed generic webhook, or an email to a per-repo address |
465
466**Actions**: open an issue (optionally assigning N agents to it), message
467a running pull request, update documentation, notify, call a
468webhook, write back to the source system.
469
470**Example: Sentry.** A new production error arrives. The automation opens an
471issue labelled `bug`, with the stack trace, release and frequency in its
472description. Why-blame
473finds the session that wrote the failing line, so the fixing agent starts
474with the original reasoning. When the fix merges, g1t comments on the Sentry
475issue and resolves it.
476
477### Rules every automation obeys
478
479- **Deduplication.** The same Sentry issue firing 500 times maps to one
480 issue.
481- **Limits.** Concurrency and budget caps per automation.
482- **Loop protection.** Work started by an automation cannot retrigger the
483 same automation without a person in between.
484- **External input is untrusted.** A webhook payload can contain text written
485 by an attacker. Agents started by external events run with reduced
486 permissions and cannot merge without the repo's approval rule passing.
487
488**Checks** are the other half of what GitHub Actions does: build and test
489commands declared in `.g1t/checks.yaml`, run in sandboxes on every pull request
490and on every combined state in the landing queue.
491
492### Tokens, scopes and packages the GitHub way (built 2026-10-08)
493
494> **2026-10-08 (owner):** "emulate all of what GitHub does for scope
495> mapping and packages." GitHub's current behaviour is the spec.
496
497This **reverses identity/0023**, which retired a token's reach to some
498workspaces or repositories and left classic tokens only. The reason it is
499reversed: the owner chose GitHub parity, and GitHub has fine-grained tokens
500beside classic ones, with workspaces (organizations) governing both.
501
502- **Fine-grained personal access tokens** (identity/0034,
503 `services/identity/src/token_reach.rs`, `g1t_contracts::fine_grained`):
504 one resource owner (a workspace the person belongs to, or their own
505 account), all, selected (up to 50, by repository id) or only public
506 repositories, and a level per permission under GitHub's names (contents,
507 metadata, issues, pull_requests, actions, workflows, checks, statuses,
508 deployments, pages, environments, secrets, variables, webhooks,
509 administration, packages, security_events; members,
510 workspace_administration, self_hosted_runners, workspace_secrets,
511 workspace_webhooks, workspace_billing, models; email_addresses, starring,
512 notifications; g1t's agents and memory). Each level maps onto g1t's
513 scopes, which the token stores, so every check that reads scopes
514 (`scopes::decide` for the API and MCP, `decide_git`, `decide_packages`)
515 reads them unchanged. They must expire, within 366 days. On each use,
516 identity cuts the resolved person down to the token's reach
517 (`apply_reach`); `access::granted` gives no role outside it, so a public
518 repository elsewhere still reads and nothing more.
519- **Governance** (`token_policies`, `token_workspace_revocations`): per
520 workspace, allow classic, allow fine-grained, require approval (on by
521 default, as GitHub's; owners' own tokens never wait), the longest
522 lifetime, and forbidding tokens that never expire. Owners see every
523 member's token that can reach the workspace, approve or deny pending
524 fine-grained ones (inbox: `token.approval_requested` and
525 `token.approval_reviewed`, the inbox's first notices about no
526 repository), and revoke one there. REST and MCP for owners; audited as
527 `token.*`.
528- **Workflow files** need `workflow_files:write` (GitHub's `workflow`
529 scope; the `workflows` permission) from any token, checked commit by
530 commit on push (`services/repos/src/workflow_gate.rs`) and on files g1t
531 writes for a token. A job's token never has it. g1t's agents push with
532 run credentials, not tokens, and are not gated by it; their work arrives
533 as pull requests people review.
534- **Workspace tokens** have Write unless an owner gives Admin at creation.
535- **Deploy keys** (identity/0035): per repository, read-only unless write
536 is ticked; resolved to a principal bound to the one repository.
537 Serving git over SSH is still to come, so nothing uses them yet.
538- **Packages** (packages/0006, `services/packages/src/access.rs` and
539 `settings.rs`): per-package roles (read, write, admin) for people and
540 teams, with "inherit access from the linked repository" (on by default);
541 "Manage Actions access", which a job's token is held to (its own linked
542 repository writes; any other repository needs an entry, added
543 automatically for the repository whose job first publishes an unlinked
544 package); linking by `org.opencontainers.image.source` (manifest
545 annotation or image label, same workspace, pusher may push there); 30-day
546 soft delete of packages and versions, registry deletes included (the name
547 and version stay reserved), restore, and a purge in the hourly cron; a
548 settings tab and a "Deleted packages" view; 17 REST operations and one
549 `package` MCP tool (reads `packages:read`; settings and access
550 `packages:write` with the package's Admin role; delete and restore
551 `packages:delete`); and download counts per version in every registry.
552 Existing unlinked packages have no Actions access entries, so workflows
553 that used them through `G1T_TOKEN` need one added.
554
555### Keeping workflow runs safe (built 2026-10-08)
556
557An audit of g1t Actions found a job's token was a full-access workspace
558token, environments had no protection, outside pull requests ran at once,
559the cache could be poisoned across branches, a job's token could set off
560more runs, and masking missed multi-line and encoded secrets. Now:
561
562- **The job's token** (`G1T_TOKEN`, `GITHUB_TOKEN`) is minted per job by
563 identity (`create_job_token`, migration identity/0030): it reaches its
564 repository only (`TokenAccess.repo`, enforced by the API, git and the
565 registries), carries the scopes its `permissions:` map to
566 (`g1t_actions::permissions`), is revoked when the job ends, and its
567 writes are audited with the run as `run_kind: workflow_job`. Without
568 `permissions:` it gets the repository's default, the GitHub way:
569 repositories that existed when actions/0007 ran keep read and write,
570 newer ones take their workspace's default (read-only unless an owner
571 says), and a workspace can cap every repository at read-only. An outside
572 pull request's is read-only. "Allow g1t Actions to create and approve
573 pull requests" (repository and workspace, off by default) decides whether
574 the token may open or approve pull requests. OIDC (`id-token: write`)
575 reads the same permissions model.
576- **No loops.** Work and repos mark the events a job's token causes
577 (`causedByJob`), carried on to a pull request it moves; the actions
578 service starts nothing for them. `workflow_dispatch` and
579 `repository_dispatch` (now sent by `POST {repo}/dispatches`) still start
580 runs.
581- **Environments' protection rules** (actions/0007): required reviewers
582 (people or teams, up to six, optionally not whoever started the run), a
583 wait timer, which branches and tags may deploy, and admin bypass. A job
584 naming one is `pending` once its needs are done, its environment read
585 then (an expression included); reviewers hear in the inbox
586 (`deployment.review_requested`) and approve on the run's page or through
587 `pending_deployments`; secrets are read only when the job starts.
588- **Approval for outside pull requests**, by a repository policy
589 (first-time contributors, outside contributors (the default), or every
590 external contributor): such runs are `action_required` until someone with
591 Write approves them.
592- **The cache is scoped by ref** (own, then the pull request's base, then
593 the default branch; outside pull requests save where nothing else reads)
594 and versioned by its paths and compression (0006's toolkit `version`,
595 which g1t's runner now sends too); g1t's `actions/cache` and the
596 toolkit's protocols share one scope rule. Entries from before were
597 expired.
598- **Masking** covers each line of a multi-line secret, base64 at every
599 offset and JSON-escaped forms; outputs holding a secret are withheld and
600 annotations masked.
601- A job's own `concurrency:` is honoured, `create` runs on new branches and
602 tags, and `on: delete` says plainly that it never runs yet.
603
604### Docker in workflow jobs (built 2026-10-08)
605
606> **2026-10-08:** "Why didn't we give CI docker then? We need GitHub
607> Actions functionality maxxed baby but with all the good good security
608> etc." The trigger: `deploy.yml`'s runner-image job needs `docker build`
609> and `docker push`, and failed on hosted runners.
610
611**What Cloudflare Containers allow** (their FAQ, updated 2026-10-05, and
612the Docker-in-Docker guide and example it links):
613
614- Docker runs inside a container: `docker:dind`, with `dockerd` as
615 **root**. A rootless Engine does not start there.
616- **No iptables**: `--iptables=false --ip6tables=false`, or the Engine
617 fails setting up its rules. Containers with the `durable_object`
618 scheduling policy (ours: each sandbox is a Durable Object's) cannot turn
619 IP forwarding on either: `--ip-forward=false`, or the Engine exits.
620- So **a bridge network has no way out**: the guide's answer is
621 `--network=host` for `docker run` and `docker build`, which gives
622 containers the outer container's network.
623- Built images and containers are lost when the sandbox stops.
624
625**What was found by trying** (Docker Engine 29.8.2 in a privileged
626container standing in for a sandbox, with the same flags):
627
628- `--bridge=none` makes BuildKit's `RUN` steps fail outright ("network
629 bridge not found"); with the default bridge they run with no route out.
630 Containers default to the bridge too. The default bridge is created
631 fine without iptables, as the FAQ's own example relies on.
632- The overlay snapshotter does not work on an overlay root filesystem, and
633 the containerd image store does not fall back by itself: the Engine
634 starts, then every container fails to mount. Whether a sandbox's disk
635 takes overlays is not documented, so the runner tries a mount first and
636 uses `native` (plain copies) when it fails. `vfs` is not a name the
637 containerd store accepts.
638- `--cpus` and `--memory` need cgroup v2 controllers handed down from a
639 cgroup with no processes, which `docker:dind`'s entrypoint does and a
640 plain `dockerd` does not.
641- A `runc` earlier on the Engine's `PATH` is used both for containers (via
642 containerd's shim) and by BuildKit's executor, with the bundle's
643 `config.json` written before it runs. BuildKit's bridged steps carry
644 libnetwork's `libnetwork-setkey` prestart hook; `RUN --network=none`
645 does not.
646- Buildx skips `type=gha` caches when the job has no GitHub cache service,
647 and the build succeeds without one.
648- Registries' layer hosts: Docker Hub sends layers from
649 `production.cloudfront.docker.com` (and `production.cloudflare.docker.com`),
650 Quay from `cdn0N.quay.io`, Microsoft's from regional
651 `*.data.mcr.microsoft.com`, public ECR from a CloudFront host;
652 `mirror.gcr.io` serves its own.
653
654**What was built** (`crates/runner/src/docker`, `actions/containers.rs`):
655
656- **One Engine per job, started lazily.** The runner listens on
657 `/var/run/docker.sock` itself and starts `dockerd` (root, the flags
658 above, containerd image store, `mirror.gcr.io` first for Docker Hub) on
659 the first connection, or when the job has `services:` or `container:`.
660 A log line says it started and how long it took.
661- **Containers on the job's network.** The socket is an API proxy: a
662 container that asks for a bridge or user network gets `host`; its names
663 (container name, aliases, Compose service, links) resolve to 127.0.0.1
664 in later containers (`ExtraHosts`) and in the job's steps
665 (`/etc/hosts`); `-p 8080:80` is forwarded; `docker inspect` reports the
666 ports as published; `network connect` adds aliases. Sharing the job's
667 network is also what keeps the guardrails on every container: the
668 egress Worker sees their traffic as the job's.
669- **A `runc` shim.** The runner binary, as `runc`: BuildKit steps bound for
670 a bridge lose the network namespace and the libnetwork hook (so they use
671 the job's network); in a guarded job every container (run, exec, build
672 step) gets the egress certificate at `/dev/g1t-egress` and the
673 variables that point tools at it. `/dev` is the container's own tmpfs,
674 so none of it lands in a layer; checked by saving a built image.
675- **Job features:** `services:` (pull, credentials, health waits, logs at
676 the end, `job.services.*`), `container:` (steps and JavaScript actions
677 through `docker exec`, Node mounted from the runner, Alpine falls back to
678 running actions beside it), `docker://` steps and Dockerfile actions in
679 GitHub's `/github/*` layout, `docker/setup-buildx-action` answered
680 natively (the job's Engine is the builder), sign-in to g1t's registry
681 with the run's token.
682- **Kill switch:** the runner Worker's `DOCKER` var (`off`).
683
684**Rejected:** rootless Docker or BuildKit (does not start in Containers);
685Podman or buildah with `vfs` (no better networking, less compatible, slow);
686a standalone `buildkitd --oci-worker-net=host` as the default builder
687(images not in the Engine's store, so `FROM` a just-built image and
688`docker run` of a build fail without `--load` round trips); a `docker` CLI
689wrapper adding `--network=host` (misses Compose, SDKs and testcontainers,
690which speak the API).
691
692**Not yet:**
693
694- Seen on Cloudflare itself: whether a sandbox's disk takes overlays,
695 `--privileged`, and the first deploy's pull of the base from
696 `registry.cloudflare.com` (its layer host may need a workflow-only line).
697- `type=gha` build caches backed by g1t's Actions cache.
698- Multi-platform builds (QEMU's `binfmt_misc` in a sandbox).
699- Docker for agents and checks, not just workflow jobs.
700- `runner-base.yml` on g1t's machines: the base's apt step needs
701 `Acquire::https::CAInfo` pointed at the egress certificate first.
702- A deploy that appends the runner binary as a layer through the registry
703 API, with no Docker and no 3 GB pull.
704
705Agents can also reach integrations directly: an agent definition lists MCP
706servers (Sentry, Linear and so on) it may use while working.
707
708### Workflows: the toolkit, OIDC and artifacts
709
710> **2026-10-08:** built so that workflows that deploy, cache and pass files
711> run unmodified.
712
713- **The toolkit's services.** Every job gets `ACTIONS_RUNTIME_TOKEN` (a
714 JWT whose `scp` names its run and job, signed with a key derived from
715 the job's own token, so nothing new is kept), `ACTIONS_RESULTS_URL`,
716 `ACTIONS_CACHE_URL` and `ACTIONS_CACHE_SERVICE_V2`. The API answers the
717 cache's Twirp service (v2) and its older REST protocol, the artifact
718 Twirp service, and the signed blob links they hand out (a subset of
719 Azure Blob's protocol mapped onto R2 multipart uploads), from the same
720 cache and artifact rows g1t's own runner uses. As the clients' source
721 reads, `@actions/cache` and `@actions/artifact` treat any server
722 but github.com as GitHub Enterprise Server, so the cache client speaks
723 the older protocol and the artifact client refuses to run. g1t's runner
724 therefore keeps handling `actions/upload-artifact`, `download-artifact`
725 and `upload-artifact/merge` itself; the Twirp artifact service is there
726 for clients that do not check.
727- **OIDC.** The issuer is `{API}/actions/oidc`, the API's own host, with
728 discovery, JWKS (RFC 7638 `kid`s, a previous key published while
729 rotating) and a token endpoint for `core.getIDToken`. Claims follow
730 GitHub's. A job gets one only when its permissions (or its workflow's)
731 give `id-token: write`, and never for an untrusted run. The permission
732 check reads only `id-token` (`services/actions/src/runtime.rs`,
733 `id_token_permitted`), the seam for the full `permissions:` model.
734- **Artifacts** moved from KV to R2 (`a/` in the cache bucket), with rows
735 in the actions service: numeric ids, 5 GiB each and 10 GiB a run,
736 zipped by the runner, `retention-days` up to the repository's setting
737 (1 to 90, 14 by default), `overwrite`, `compression-level`, patterns,
738 merging and other runs of the same repository. The REST artifacts API and
739 the `workflow` tool's artifact actions follow GitHub's shapes; the run's
740 page lists them with size and expiry, with download and delete. Their
741 storage is charged with the cache's.
742- **Later:** the toolkit's older artifact protocol (`upload-artifact@v3`
743 inside other actions), downloads from other repositories, and npm
744 trusted publishing, which depends on npm accepting g1t's issuer.
745
746### Actions parity: other repositories, triggers, step timeouts (built 2026-10-08)
747
748- **Other repositories' actions and reusable workflows**
749 (`services/actions/src/reach.rs`, actions/0008): `uses: owner/repo@ref`,
750 `owner/repo/path@ref` and `jobs.<id>.uses: owner/repo/.g1t|.github/workflows/x.yml@ref`
751 are looked for on g1t first, as the calling workspace sees them. Same
752 repository or public: used. Private: only from a private repository of
753 the same workspace, when its **Settings → Actions → Access** (`access_level`,
754 `GET`/`PUT …/actions/permissions/access`, MCP `get_access`/`set_access`)
755 says `organization`; a job fetches such an action with a read-only token
756 for that repository, revoked with the job (`job_action`, the runner's
757 `POST /actions/jobs/{job}/action`). Not on g1t: actions from GitHub as
758 before, reusable workflows from a public GitHub repository. A `./` call
759 inside a called workflow reads from that workflow's own repository.
760- **Secrets for called workflows** follow GitHub: none but the job token
761 unless the caller passes `secrets:` by name or `secrets: inherit`;
762 required secrets are checked before the call; a called job's
763 `environment:` reads that environment's secrets over what was passed. The
764 mapping is kept with the called jobs and read when each starts, so no
765 secret is stored. (Before, same-repository called workflows read every
766 repository secret.)
767- **Triggers:** `release` (created, published, released, prereleased,
768 edited, unpublished, deleted; repos now publishes `release.*`),
769 `deployment` and `deployment_status` (from the deployments service's
770 events; ones an Actions job or a job token made are marked
771 `causedByJob` and start nothing), `pull_request` `reopened` and
772 `converted_to_draft`, `issue_comment` `edited` and `deleted` (work
773 publishes `pull.reopened`, `pull.converted_to_draft`, `comment.edited`
774 and `comment.deleted`).
775- **`timeout-minutes` on every step**, `uses:` included: the runner keeps a
776 step deadline every process it starts stops by, nested composite steps
777 taking the nearer one.
778- **Not yet:** a deployment's `ref` that is neither a branch nor a commit
779 is read as a tag; `on: delete`.
780
781### Runs: summaries, attempts, cancelling, logs and badges (built 2026-10-08)
782
783GitHub Actions parity on the run itself:
784
785- [x] **Job summaries.** The runner sends each step's
786 `$GITHUB_STEP_SUMMARY`, masked, as a `summary` report (1 MiB a step,
787 20 steps a job, kept in `job_summaries`, actions/0009); the run's page
788 renders them as sanitised Markdown, a card per job.
789- [x] **Attempts and re-runs.** A re-run is a new attempt that keeps the
790 one before (`run_attempts`, `job_attempts`; a re-run job's logs and
791 summary move to `{job}.{attempt}`, which is its id when that attempt is
792 viewed). Re-run all, failed, or one job (`POST …/jobs/{job}/rerun`) with
793 the jobs that need it; a matrix or a called workflow runs again whole.
794 Debug re-runs set `RUNNER_DEBUG=1`, `ACTIONS_STEP_DEBUG`,
795 `ACTIONS_RUNNER_DEBUG` and `runner.debug`; the runner then shows
796 `::debug::` lines and how each step's `if:` read. An attempt picker on
797 the run's page, `attempt` on `get_workflow_run` and
798 `…/runs/{id}/attempts/{n}`.
799- [x] **Graceful cancel.** A running job gets `cancel_requested_at`,
800 told in the answer to its next report (a quiet step pings every 10 s):
801 the step's process group gets SIGINT, SIGTERM at 7.5 s, SIGKILL at 10 s;
802 then only `always()`/`cancelled()` steps and post steps run, and the job
803 ends `cancelled`. Hard-stopped after 5 minutes; cancelling again or
804 `…/force-cancel` stops at once.
805- [x] **Logs.** Search on the run's page (matching lines, groups opened);
806 one job's log as text (`…/jobs/{job}/log.txt`, API
807 `…/jobs/{job}/logs?format=text`) and an attempt's as a zip laid out as
808 GitHub's (`…/runs/{id}/logs.zip`, API `…/runs/{id}/logs`), up to 24 MiB.
809- [x] **Status badges** at `/{ws}/{repo}/actions/workflows/{file}/badge.svg`
810 with `branch` and `event`; public repositories' for anyone (cached a
811 minute), private ones' only for viewers who can see them. "Create status
812 badge" on the workflow's page gives the Markdown.
813- Not yet: re-running one combination of a matrix alone; signals into a
814 job container's processes on cancel (they reach `docker exec` only).
815
816## A repository that maintains itself
817
818> **2026-10-04:** the user asked for Dependabot, GitHub Advanced Security and
819> Vercel-style deployments, "so you're not having to maintain shit and you're
820> just pushing up agents that are delivering work consistently".
821
822GitHub reports problems and leaves the fix to you. In g1t, an agent opens an
823issue for each problem, writes the fix, runs its checks, links a preview and
824lands it through the queue. People only decide.
825
826### Upkeep agents
827
828- **Dependency updates.** The file is `dependabot.yml` version 2, read from
829 the default branch at `.g1t/dependabot.yml` (or `.yaml`), then
830 `.github/dependabot.yml` (or `.yaml`); `.g1t/` wins when both exist, and
831 an imported repository's file works unchanged. Every option is read and
832 checked, each problem reported with its line and key on the Security page
833 and as the `g1t / dependabot.yml` status on pull requests that change the
834 file; a file with problems is not acted on.
835 - **Built (2026-10-07):** version updates for npm, cargo, gomod and pip:
836 schedules (all intervals, cron and natural phrases, time zones, a
837 picked time per repository), allow, ignore, cooldown (3 days by
838 default), groups (including across directories and `group-by`),
839 versioning strategies, open-pull-requests-limit, commit-message,
840 branch names, rebase-strategy, assignees, reviewers, private
841 registries filled from workflow secrets (npm, cargo, Go proxy, Python
842 index), and the `@g1t` comment commands. Pull requests come from g1t
843 with an `updated-dependencies` commit record and land through the
844 required checks; one that fails them is closed and becomes a
845 "needs code changes" issue assigned to g1t.
846 - **Security updates follow the same file:** ignore (and comment
847 ignores), allow names, `applies-to: security-updates` groups,
848 commit-message, assignees, reviewers, labels and milestone. Cooldown
849 and the open pull request limit do not apply. The Security updates
850 switch still turns them on and off.
851 - **Labels, milestone and target-branch** are applied to version
852 updates: `dependencies` and the ecosystem's label by default, missing
853 labels created; `target-branch` updates are made from that branch and
854 merge into it.
855 - **Not done yet:** one pull request for a multi-ecosystem group
856 (it opens one per ecosystem); registries that sign in with OIDC;
857 updating vendored copies; and version updates for the other
858 ecosystems (bundler, composer, docker, github-actions, gradle, maven,
859 nuget, terraform, uv and the rest are read and checked only).
860- **Secret scanning.** Pushes are scanned for known token formats. A push
861 that adds a secret is refused with the file and line; one already in
862 history opens an issue to rotate it and remove it.
863- **Vulnerability alerts.** Dependencies are matched against the OSV
864 database. Every alert links to the issue and pull request fixing it.
865- **Code scanning.** A reviewer agent reads each pull request's diff for
866 security problems and leaves findings as review comments with a
867 suggested fix. Findings on `main` open issues.
868- **A security page per repository** lists alerts, secrets and findings,
869 with the agent work on each, like GitHub's Security tab.
870
871All of these are event sources for the existing issue → agent → checks →
872queue pipeline; they need no new kind of work.
873
874### The security suite (built 2026-10-07)
875
876GitHub Advanced Security's depth, in g1t's shape (services/security,
877`g1t_contracts::security_suite`, docs `guides/security/*`):
878
879- **Secret protection.** Custom patterns (repository and workspace; Rust
880 `regex`, linear time, size-limited; test strings; dry run over the
881 default branch) used by push protection, `commit_file` and history
882 scans. Bypass with a reason (false positive, used in tests, will fix
883 later), recorded on the alert and in the audit log; delegated bypass
884 (requests reviewed by owners and repository admins, through the inbox).
885 Validity checks for GitHub, GitLab, Stripe, Slack, npm, OpenAI,
886 Anthropic and SendGrid tokens, made by the repos service, which reads the
887 landed secret again: the value never leaves it except to the issuer. AWS
888 keys (need their secret key to sign) and webhook addresses (would post)
889 are the extension points left (`g1t_scan::validity::check_for`).
890- **Code scanning.** SARIF 2.1.0 uploads → alerts with fingerprints (tool
891 partial fingerprints first), fixed when no longer reported; pull request
892 uploads → line comments and the `Code scanning` commit status, gated by a
893 per-repository threshold and required like any check. Starter workflow:
894 a scanner per language present, each uploading its own category: Bandit
895 (Python), gosec (Go), ESLint + eslint-plugin-security with the SARIF
896 formatter (JS/TS), Clippy + clippy-sarif (Rust); all install from the
897 registries the runner's egress already allows. Semgrep's registry rules
898 and the Opengrep rules fork are not usable in a paid feature, so neither
899 is used. "Fix with g1t" opens an issue and runs the agent.
900- **Supply chain.** Dependency graph (direct/transitive where the lockfile
901 says, npm licenses), SPDX 2.3 SBOM, `Dependency review` status on every
902 pull request (OSV severity threshold, license deny list, summary comment).
903- **Overview.** Workspace totals, opened/closed, a daily snapshot trend,
904 coverage, repositories most in need first.
905- **Paid.** The Security and quality activation on private repositories;
906 free on public ones; the free core (secret scanning, push protection,
907 vulnerability alerts, security updates, dependency graph) free everywhere.
908
909Not built yet:
910
911- **The reviewer agent as an analysis source.** g1t's reviewer reads each
912 pull request's diff (`agent_review`), but its findings are review
913 comments, not SARIF. Next: have it emit SARIF for the security issues it
914 finds and upload them as the tool `g1t review`, so they become alerts and
915 count toward the Code scanning check.
916- **Repository security advisories.** Private advisories, draft →
917 published, with affected versions (ranges per ecosystem), severity and a
918 CVSS vector, credits, and a private fork (a `g1t/advisory/GHSA-…` working
919 copy only the advisory's collaborators can see) for the fix, merged into
920 the default branch when the advisory publishes. Published advisories
921 should feed the OSV-shaped data other g1t repositories' vulnerability
922 alerts read. CVE requests are out of scope. Needs: an `advisories` table
923 per repository, a collaborator list per advisory, the private-fork
924 visibility rule in repos, and an Advisories page on the Security tab.
925- **SARIF upload as a background job.** Uploads are read in the request
926 (10 MB encoded, 40 MB unzipped, 5,000 results); larger ones need a queue.
927
928### Deployments
929
930- **A preview for every pull request**, at
931 `<pr>--<repo>--<owner>.g1t.page`, linked on the pull request and updated
932 on each push. `main` deploys to `<repo>--<owner>.g1t.page`, and a
933 repository can add its own domain.
934- **On g1t.page, not g1t.sh,** so customer code never shares cookies or an
935 origin with the site people sign in to.
936- **Built on Workers for Platforms.** Each deployment is a user Worker in a
937 dispatch namespace; one dispatch Worker on `*.g1t.page` routes to it. The
938 build runs in the same runners as Actions. Static sites and Workers apps
939 first; container apps and databases later.
940- **Agents use the preview.** The reviewer agent opens the preview in a
941 browser, takes screenshots of what changed and attaches them to its
942 review, so an approver sees the result without reading the diff.
943- **Environments.** Preview, production and their secrets; deploy history
944 and one-click rollback.
945- **Scale to zero.** An idle branch costs neither g1t nor the customer
946 anything: a Worker runs, and is billed, only while it answers a request.
947 A preview is deleted when its pull request closes or merges, and after
948 a set number of idle days. Container apps, later, sleep when idle.
949- **Billed to the customer, never free.** The user (2026-10-04): "we
950 should not be giving any of this available for free". Every deployment
951 is metered per workspace (requests, CPU time, deployed apps, stored
952 data), priced at Cloudflare's cost + 20% like agent usage, and drawn
953 from prepaid credit. `FREE_WHILE_BUILDING` and the free model allowance
954 do not cover deployments: a workspace without credit cannot deploy, and
955 turning deployments on says so first.
956- **Turning them on is a paid plan, the way Cloudflare's is.** "Including
957 things like them even enabling the feature should have that pay like
958 Cloudflare does." Enabling deployments for a workspace starts a monthly
959 fee that includes an allowance of requests, CPU time and deployed apps;
960 usage past it is billed per unit, as Workers for Platforms bills g1t.
961 The fee and allowance are the user's to set.
962- **Recommended, off in one click.** Because enabling costs money, it is
963 never switched on without the workspace agreeing: new repositories
964 recommend it prominently. A repository can turn it off, keep only production, or
965 deploy somewhere else from its own workflows. Apps built for Cloudflare
966 (Workers, static assets, D1, KV, R2) deploy without configuration.
967
968Later, toward GitLab's DevOps breadth: package and container registries,
969releases, container hosting. (Environments' protection rules for g1t
970Actions were built on 2026-10-08; see above.)
971
972## Projects
973
974> **2026-10-04:** the user: "an extra dimension of Projects so it's not
975> just repositories … where a lot of things can live", "very Vercel
976> like", with dependencies across projects "the Platform Engineering /
977> Port route", and "the repository is *part* of a project: you could be
978> mirroring it from GitHub/GitLab/Bitbucket, or you could let us host it
979> for you", with room for Mercurial or anything else later.
980
981**A project is the thing you are building and running; a repository is
982where some of its code lives.** Everything that is about running software
983(deployments, environments, domains, secrets, dependencies, owners,
984health, upkeep) belongs to the project. What is about the code itself
985(branches, pull requests, review, merge rules) stays with the repository.
986That split is what lets the code live anywhere.
987
988### The model
989
990| | What it is | Like |
991| --- | --- | --- |
992| **Workspace** | The company or team. Members, billing, plans, shared secrets. | Vercel team, GitLab group, GitHub org |
993| **Group** | An optional named set of projects, one level: "Payments", "Mobile". For browsing, ownership and shared settings. | GitLab subgroup, Backstage system, Port domain |
994| **Project** | One deployable thing: a site, an API, a worker, a library. Has exactly one **source**. | Vercel project, Port service, Backstage component |
995| **Source** | Where its code is: a repository and a **root directory** in it. | Vercel's connected repo + root directory |
996| **Dependency** | Project A uses project B: calls its API, consumes its package, reads its queue. | Port relations, Backstage `dependsOn` |
997
998- **One project, one source; one repository, any number of projects.** A
999 project builds from exactly one place, which keeps it as simple as
1000 Vercel's. A monorepo is several projects on one repository, each with
1001 its own root directory (`apps/web`, `services/api`), and a push builds
1002 only the projects whose root it touched. The common case stays 1:1, and
1003 every existing repository gets a project of its own name when this
1004 ships, so nobody has to set anything up.
1005- **Groups are for people; dependencies are for software.** Groups decide
1006 where a project shows up and who owns it. Dependencies decide what
1007 happens when one changes. Neither replaces the other, and a dependency
1008 can cross groups.
1009
1010### Sources: where the code lives
1011
1012A source is an adapter behind one interface (`SourcePort`: clone URL,
1013branches, commits, pushes as events, pull requests if it has them):
1014
1015| Source | Code lives | g1t gets pushes by | Pull requests |
1016| --- | --- | --- | --- |
1017| **Hosted on g1t** (today) | Artifacts | its own events | g1t's, with agents, the queue, review |
1018| **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 |
1019| **Connected, not copied** | The provider only | webhook | The provider's |
1020| **Later:** Mercurial, Perforce, a tarball upload | Behind the same port | per adapter | per adapter |
1021
1022A mirrored or connected project still gets everything that is the
1023project's: previews on its pull requests (a status and a comment on
1024GitHub's), production on its default branch, secrets, dependencies,
1025upkeep agents. That is the on-ramp: a team keeps GitHub and gets g1t's
1026deployments and agents first, and moves the code later or never.
1027Bring-your-own-git is also why the project, not the repository, holds the
1028URL `g1t.sh/<workspace>/<project>`.
1029
1030### What lives on a project
1031
1032| | Today it is on | Moves to the project |
1033| --- | --- | --- |
1034| Deployments: production, previews, build settings, root directory, framework | The repository | Yes |
1035| Environments: production, preview, and custom ones (`staging`) with protection rules (required approvers, branch limits) | Nowhere yet | New, on the project |
1036| Domains: `<project>--<workspace>.g1t.page`, and custom domains | The repository's name | Yes |
1037| 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). |
1038| Dependencies | Nowhere | New |
1039| Owners, on-call, links (docs, dashboards, runbooks) | Nowhere | New: the catalog's metadata |
1040| Health: scorecards (has an owner, CI passes, dependencies current, no open security alerts, deploys within N days) | Nowhere | New |
1041| Upkeep agents: dependency updates, security alerts | The plan | Scoped per project |
1042| Logs and analytics of the running app | Nowhere | New: requests, errors and CPU per environment, from Workers analytics |
1043| Branches, pull requests, review, merge rules, the queue, webhooks | The repository | Stay |
1044
1045### Dependencies: why this gets powerful
1046
1047Declared in the UI, or in the source as `.g1t/project.yml` (which wins
1048when present, as `catalog-info.yaml` does in Backstage):
1049
1050```yaml
1051name: web
1052root: apps/web
1053dependsOn:
1054 - project: api # calls its HTTP API
1055 as: API_URL # its URL, per environment, as a variable
1056 - project: ui-kit # consumes its package
1057```
1058
1059What g1t does with them:
1060
10611. **Reference variables.** `API_URL` above resolves to `api`'s production
1062 URL in production and to the matching preview in a preview, the way
1063 Railway's `${{ api.URL }}` references work. No hard-coded URLs.
10642. **Preview stacks.** A pull request on `api` gets its own preview, and
1065 **Preview with dependents** builds `web`'s preview pointed at it, so a
1066 reviewer clicks through the whole change across projects. A change that
1067 spans repositories (one issue, one fork per repository) gets one stack.
10683. **Release order.** Production deploys go out in dependency order; a
1069 change set across projects lands through the queue together or not at
1070 all.
10714. **Impact on every pull request.** "Changes `api`; `web` and `mobile`
1072 depend on it." Agents get the graph in their context: an agent
1073 changing an API opens follow-up issues on the projects that call it,
1074 and reviewers see what else could break.
10755. **Upkeep across the graph.** A vulnerable package in `ui-kit` opens
1076 issues, assigned to agents, on every project that consumes it.
10776. **Scorecards turn into work.** A project failing a scorecard check
1078 ("no owner", "dependencies 90 days old") gets an issue an agent can fix.
1079 That is the Port idea with the work done for you.
10807. **The map.** A workspace's projects as a graph, coloured by health and
1081 by what is deploying now.
1082
1083### Pages
1084
1085- `g1t.sh/<workspace>`: projects first (grouped, with health and
1086 production status), then repositories.
1087- `g1t.sh/<workspace>/<project>`: overview (production, latest previews,
1088 health, owners, dependencies both ways), **Deployments**,
1089 **Environments**, **Secrets and variables**, **Logs**, **Settings**
1090 (source, root directory, build, domains, groups, owners).
1091- A hosted repository keeps its code pages; from a project they are its
1092 **Code** tab. A repository page lists the projects built from it.
1093
1094### Services
1095
1096- `services/projects` (new): projects, groups, sources, dependencies,
1097 owners, scorecards. Events `project.created`, `project.updated`,
1098 `dependency.changed`.
1099- `services/deployments`: keyed by project instead of repository.
1100- Secrets and variables: the scope becomes workspace → project.
1101- Sources: the hosted adapter wraps `services/repos`; a mirror adapter
1102 per provider in `services/integrations`, which already holds those
1103 connections.
1104
1105### Build order
1106
11071. **Projects as the home of deployments and secrets**, 1:1 with every
1108 existing repository: the service, the pages, deployments and secrets
1109 moved to the project, `<project>--<workspace>.g1t.page`.
11102. **Dependencies:** declared in the UI and `.g1t/project.yml`, reference
1111 variables, impact on pull requests and in agents' context, the map.
11123. **Preview stacks** and cross-project change sets.
11134. **Monorepos:** several projects on one repository, each with a root
1114 directory, building only what a push touched.
11155. **Mirrored sources:** GitHub first, then GitLab and Bitbucket.
11166. **Groups, owners, scorecards** feeding the upkeep agents.
11177. **Environments** with protection rules; custom domains; logs.
1118
1119**Step 1 shipped 2026-10-04:** `services/projects`; every repository a
1120project of its own name; the site projects-first (workspace page of
1121project cards, the project overview at `g1t.sh/<workspace>/<project>`, code
1122under `/code`, the sidebar and the New project flow); deployments keyed by
1123project and branch at `<project>-<workspace>.g1t.page` and
1124`<project>-git-<branch>-<workspace>.g1t.page`; secrets and variables owned
1125by the project.
1126
1127**Step 5, GitHub, built 2026-10-05:** one GitHub App (`g1t-sh`) for both
1128sign-in and repository access. Sign-in is its user authorization with PKCE
1129(identity, `src/github.rs`): accounts known by GitHub's numeric id, a
1130matching verified email never linked without signing in to the account,
1131new accounts behind the invite check. Repositories come through its
1132installations (integrations, `src/github.rs`), copied with every branch and
1133tag by the repos service (`src/mirror.rs`) as **import**, **mirror** (g1t
1134follows GitHub on its push webhook) or **move to g1t** (GitHub follows g1t
1135on `git.push`). A mirror is a hosted repository that keeps a full copy, so
1136its project stays `hosted` and deploys like any other; the tie lives in
1137integrations' `github_repos`. Not yet: previews and statuses on GitHub's own
1138pull requests, comments and pull requests copied, GitLab and Bitbucket.
1139
1140### People and search
1141
1142> **2026-10-04:** "pull up user profiles, using a /u/username prefix kinda
1143> like DockerHub … search for users if you search that explicitly, how
1144> GitHub has the aside for searching against filters … a significantly
1145> stronger implementation."
1146
1147- **Profiles at `g1t.sh/u/<username>`**, apart from workspaces at
1148 `g1t.sh/<workspace>`: who they are, their workspaces, recent work,
1149 agents' sessions they steered.
1150- **Search with a filter sidebar:** Projects, Code, Issues, Pull requests,
1151 Users, Workspaces, each with its count; filters by workspace, language,
1152 state, author, agent, label, date; qualifiers in the query
1153 (`user:`, `is:open`, `agent:g1t`) as on GitHub. Typing `u/name`
1154 searches people directly, as Docker Hub does.
1155
11561 and 2 serve the competition directly (multi-agent coordination across
1157projects is 25% of the score); 3 is the demo's best moment if time allows.
1158
1159## Billing model
1160
1161> **2026-10-04:** "Some things just require you to have a card on file …
1162> some things will be something you give us an initial amount of money
1163> per month just to activate, tons of things additionally will be usage
1164> based, some things will just be usage based only … at minimum a
1165> breakeven with Cloudflare costs, or in some cases a value add." Stripe
1166> moves to Flagon, Inc. (g1t.sh is its product). Proposed below; the
1167> prices are the user's to confirm.
1168
1169### Four kinds of charge
1170
1171Every feature is exactly one of these, and the Billing page says which:
1172
1173| Kind | What the workspace does | Example |
1174| --- | --- | --- |
1175| **Free** | Nothing | Hosting code, issues, pull requests, review, the merge queue, bringing your own agent over MCP |
1176| **Card on file** | Adds a card; pays only for what it uses | Previews, g1t's agents, workflow minutes |
1177| **Activation** | Turns a feature on for a monthly fee that includes an allowance; usage past it is metered | Production deployments, Security and quality |
1178| **Usage only** | Nothing up front; every unit is metered | Model tokens, build minutes, storage past the free amount |
1179
1180A card is needed before anything that can cost money starts. Nothing is
1181ever switched on without the workspace choosing it.
1182
1183### Postpaid, with spend limits
1184
1185- **One Stripe customer and one subscription per workspace**, on Flagon,
1186 Inc.'s account. Activations are licensed line items; every usage
1187 dimension is a metered price backed by a Stripe Meter. Stripe invoices
1188 monthly in arrears and charges the card on file; failed payments go
1189 through Stripe's retries and emails, and g1t hears of them by webhook.
1190- **Spend limits instead of prepaid credit.** A workspace sets a monthly
1191 limit overall and per feature (Vercel's spend management). g1t counts
1192 usage as it happens and stops starting new paid work at the limit,
1193 with a warning at 50%, 80% and 100%. Prepaid top-ups go away; promotions
1194 (the free model allowance) become Stripe credit on the customer.
1195- **Usage reaches Stripe from billing alone.** Every service reports
1196 usage to the billing service as it happens (it already records agent
1197 runs and builds); billing batches them into Stripe meter events every
1198 few minutes, idempotently by g1t's own ids, and keeps the ledger g1t's
1199 pages show. Nothing else talks to Stripe.
1200
1201### Scope: workspace, then projects
1202
1203- A feature is turned on for the **workspace** (by an owner, with the
1204 activation if it has one), then allowed for **all projects** or
1205 **selected projects**.
1206- Every **project** can opt out on its own page. A project with nothing
1207 to deploy (no Workers config, no build script, no `index.html`) is
1208 detected, says so on its Deployments page, and never builds or costs
1209 anything.
1210- Agents and workflows are allowed per project the same way, so a
1211 workspace can keep spend to the projects that matter.
1212
1213### Prices: what it costs us, passed through
1214
1215> **2026-10-04, decided:** postpaid with spend limits, as Vercel and
1216> Cloudflare do; no per-seat price, ever ("fuck per-seat pricing").
1217> "If they're barely using them great, but if they're using the shit out
1218> of them that will cost me a ton, so that cost needs to move onto them."
1219
1220**Every Cloudflare cost a workspace causes is metered to it.** Light use
1221fits in a small free allowance; past it, each unit is charged at
1222Cloudflare's price times a margin of at least 1.5, which pays for Stripe
1223(about 3%), shared overhead (the site, the API, D1) and g1t itself.
1224
1225Cloudflare's prices (October 2026), and the cost per unit g1t meters:
1226
1227| What g1t meters | Cloudflare's price | Cost to g1t per unit |
1228| --- | --- | --- |
1229| **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) |
1230| **App request** (deployments) | Workers for Platforms: $0.30 / million past 20M | $0.30 / million |
1231| **App CPU** | $0.02 / million CPU-ms past 60M | $0.02 / million ms |
1232| **App** (a deployed script) | $0.02 / script-month past 1,000 | $0.02 / app-month |
1233| **Storage** (repositories, artifacts, caches) | Artifacts $0.50 / GB-month (billing starts 2026-10-14); KV $0.50 / GB-month | $0.50 / GB-month |
1234| **Git operation** (clone, fetch, push) | Artifacts $0.15 / 1,000 past 10,000 | $0.15 / 1,000 |
1235| **Model tokens** | The provider's price | As charged |
1236| Container egress, emails, the site's own requests | Small and shared | In the margin |
1237
1238> **2026-10-06, decided:** no per-feature quotas on the plan. "A paying
1239> user should be able to push past the Git operations number, they're
1240> just paying usage on it." One plan, $20 a month per workspace with $10
1241> of usage included; every meter is charged from the first unit at cost +
1242> 20% (builds, app requests and CPU, custom domains), drawn from the $10
1243> first, then up to the spend limit, which is the only thing that stops a
1244> paying workspace (with abuse protection). Projects, previews and apps
1245> are not metered (Workers for Platforms' script pool makes them ~free).
1246> The forge's free amounts are the same for everyone: 1 GB private storage
1247> and 50,000 git operations a month; past them the plan pays and a free
1248> workspace is held (pushes stop, git slowed). The table below is the
1249> earlier proposal; billing's price book and g1t.sh/pricing are current.
1250
1251What a workspace pays:
1252
1253| Meter | Free each month | Then | Margin | For comparison |
1254| --- | --- | --- | --- | --- |
1255| 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 |
1256| App requests | 1 million with Deployments | $0.50 / million | 1.7× | Vercel $0.60 / million invocations |
1257| App CPU | 3 million ms with Deployments | $0.04 / million ms | 2× | Vercel active CPU about $0.036 / million ms |
1258| Apps | 10 with Deployments | $0.05 / app-month | 2.5× | |
1259| Storage | 1 GB | $1.00 / GB-month | 2× | GitHub LFS $0.07 / GB, but repositories are free there |
1260| Git operations | 10,000 | $0.30 / 1,000 | 2× | |
1261| g1t's models | | Cost + 20% | 1.2× | The provider's own price |
1262| Your own model provider | | Only its sandbox minutes (the $0.10 run fee was dropped 2026-10-05) | | |
1263| **Deployments** activation | | $5 / month, with the allowances above | covers Workers for Platforms' $25 / month across workspaces | Vercel Pro $20 per seat |
1264| **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 |
1265
1266A workspace that uses g1t lightly (a few agent runs, a small site)
1267pays nothing or its activation; a workspace running agents all day pays
1268for the sandboxes and models those agents use, with g1t's margin on
1269each. Nothing in a workspace's bill is subsidised by another's.
1270
1271### Build order
1272
12731. Stripe customer per workspace and card on file (Checkout in setup
1274 mode), webhooks (invoice paid and failed, subscription changes,
1275 payment method changes), the Billing page rebuilt around the four
1276 kinds.
12772. One subscription per workspace with activations as items; Deployments
1278 moves onto it.
12793. Meters for each usage dimension above, fed from billing's ledger:
1280 every sandbox reports how long it ran when it stops (agents, checks,
1281 the queue, workflow jobs and deploy builds alike); deployments report
1282 requests, CPU and apps; repos report storage and git operations. Spend
1283 limits and their warnings; prepaid credit retired.
12844. Per-workspace allow-lists of projects for each feature, and per-project
1285 opt-out; "nothing to deploy" detection.
12865. Turn off FREE_WHILE_BUILDING when the user says so. **Done 2026-10-05.**
1287
1288Shipped by 2026-10-05: sandbox seconds for every sandbox; the price book
1289and its keeper (runs settled to AI Gateway's price every 15 minutes;
1290Container and Workers costs checked against Cloudflare's billable usage
1291and container analytics daily, with a public change log on
1292g1t.sh/pricing); usage limits by trust with automatic payment near the
1293limit; app traffic counted toward limits as it happens; billing accounts,
1294terms and enterprises; free mode off, syntaqx comped.
1295
1296Still to build, in order: Stripe card-on-file without a payment (setup
1297mode) and webhooks; month-end invoices for postpaid usage (and one
1298invoice per enterprise); the subscription with activations as items;
1299storage and git-operation meters; limit warnings by email at 50/80/100%;
1300self-serve enterprise management for enterprise owners.
1301
1302### Accounts, terms and enterprises
1303
1304Every workspace is paid for by a billing account: its own (`ws_<slug>`)
1305or an enterprise's (`ent_…`), which pays for several workspaces with one
1306limit, one set of terms and, once invoices exist, one bill, as GitHub
1307Enterprise does. Terms are standard, comped (nothing charged, usage still
1308recorded at cost, paid features on) or custom (a discount, its own
1309ceiling, an end date). g1t staff manage them in **sudo.g1t.sh**, a
1310separate Worker behind Cloudflare Access that also verifies the Access
1311token itself and allows only listed staff emails; every change is kept
1312with who made it and why.
1313
1314### Limits: stop non-payers, never payers
1315
1316The limit is on usage not yet paid for, counted at cost to g1t or charge,
1317whichever is more: $3 before any live payment, then twice what has been
1318paid ($25 to $1,000), or what staff set. A workspace with a card on file
1319is charged automatically near its limit, which both pays what it owes and
1320raises the limit, so paying users are never stopped. A declined card
1321stops work until paid. The owner's own spend limit always means stop.
1322Test-mode payments never lower exposure or raise trust.
1323
1324### Tax, card fees and free workspaces (built 2026-10-08)
1325
1326> **2026-10-08, decided:** Stripe Tax everywhere ("so I don't fuck up on
1327> taxes"); Stripe's card fee passed to the customer with the 20% markup
1328> kept; one free workspace per person; no invites on free workspaces.
1329
1330- **Stripe Tax on every payment.** `automatic_tax` on every Checkout page
1331 (plan, Security and quality, prepaying, AI credit), every subscription
1332 and every invoice g1t makes (month close, threshold, enterprise), and a
1333 tax calculation and transaction for auto-reload's off-session charge.
1334 Tax code `txcd_10103001` (SaaS, business use), every price
1335 `tax_behavior=exclusive`. Checkout always collects the billing address
1336 and tax ID and saves them on the customer. Prices on g1t are shown
1337 excluding tax. Tax is never revenue: balances and plan payments are
1338 credited without it, it is kept in `tax_and_fees`, shown as its own
1339 statement line, and as **Tax collected** on sudo's Costs. Without an
1340 address g1t does not charge: the owners are asked for one.
1341- **The card fee** (2.9% + $0.30, grossed up) is its own line on every
1342 card payment, the plan's and Security's as a monthly item; never on a
1343 bank transfer or an enterprise's invoice. On by default
1344 (`cost_settings.card_fee`). Not revenue either. Meters stay at cost +
1345 20%; models at the provider's price plus the agent rate.
1346- **One free workspace per person.** Identity asks billing
1347 (`free_workspaces`) before creating one; a second is refused with the
1348 way forward. Those who own several from before keep them.
1349- **A free workspace adds no one**: no members, invites or outside
1350 collaborators until it starts the plan; its members stay; @g1t never
1351 counts. Enforced in identity for every path (site, API, MCP).
1352- Details: docs/BILLING_OPERATIONS.md, *Tax and the card fee*.
1353
1354### Promo codes (planned)
1355
1356Staff credits (promotional, goodwill, refund; `services/billing/src/grants.rs`,
1357docs/BILLING_OPERATIONS.md) are given one workspace at a time. Promo codes
1358give promotional credit in bulk, on redemption, through the same grants:
1359
1360- **Codes.** sudo → Credits & refunds → **New code**: the code (or one
1361 made up), the credit ($ amount), max redemptions, when the code stops
1362 working, how long each redeemed credit lasts (an expiry, as any grant),
1363 and a note. Table `promo_codes` (code, amount, max, redeemed, ends_at,
1364 credit_days, note, created_by, disabled_at) and `promo_redemptions`
1365 (code, workspace, grant id, by, at), unique on (code, workspace).
1366- **Redeeming.** An owner types it on the workspace's Billing page
1367 (`redeem_code`, owners only). One D1 batch checks the code is open, under
1368 its max and not redeemed by the workspace, counts the redemption and
1369 makes the grant (`grant_credit`, kind promotional, the code as its note),
1370 so two redemptions at once never pass the max. Wrong or used-up codes say
1371 so without telling which codes exist; redemptions are rate-limited per
1372 owner.
1373- **Seeing them.** Each code's redemptions, credit given and spent come
1374 from the grants it made, so margin needs nothing new: spent promo credit
1375 is already given away, by kind.
1376- **Not yet built** because it adds an owner-facing form, abuse limits and
1377 a second sudo form; giving credit by workspace covers launch.
1378
1379## Agents and models
1380
1381### Defining an agent
1382
1383An agent is a file (`.g1t/agents/<name>.md`, or in the workspace library):
1384instructions, the harness and model to run, the tools and MCP servers it may
1385use, its sandbox image, permissions and budget. Agents take roles: planner,
1386implementer, reviewer, conflict resolver, documenter, memory consolidator.
1387Each role has a default that a repo can replace.
1388
1389### Where it runs, and on whose model
1390
1391| Option | How it works | Fits |
1392| --- | --- | --- |
1393| Hosted, g1t's model | g1t runs the sandbox and bills usage | Getting started; no keys to manage |
1394| Hosted, your API key | Same sandbox, your Anthropic, OpenAI or Google key | Teams with existing contracts |
1395| Hosted, your endpoint | Any OpenAI-compatible URL: Bedrock, Vertex, Azure, a self-hosted model | Private or fine-tuned models |
1396| Your runner | A g1t runner daemon on your own machines picks up pull requests | Code or models that may not leave your network |
1397| Your own session | Local Claude Code, Cursor or any MCP client joins through `mcp.g1t.sh` | Individuals; subscription plans |
1398
1399Decisions behind this:
1400
1401- **g1t does not build its own agent loop.** It runs existing harnesses
1402 (Claude Code first, through its headless mode) behind a small runner
1403 contract: a container image, an entry command, and session events reported
1404 through the CLI. Other harnesses plug in by meeting the contract.
1405- **All hosted model traffic goes through Cloudflare AI Gateway.** That gives
1406 one place for spend tracking, budgets, rate limits, fallback and logs,
1407 whichever provider or endpoint is behind it.
1408- **Nobody has to pick a model.** A person assigns work to `g1t`, as
1409 they would assign an issue to a colleague, and **Auto** routes each job
1410 to the cheapest model that can do it (see
1411 [Routing for cost](#routing-for-cost) below). A workspace can pin a tier
1412 per kind of work instead. Each request is tagged at the gateway with the
1413 kind of work, the tier, the repository and the pull request, and each
1414 run says which model ran and why. The gateway's own dynamic routes
1415 cannot make the choice yet: they work only on its OpenAI-compatible
1416 endpoint, and the harness speaks Anthropic's.
1417- **Subscriptions stay local.** A Claude subscription cannot be used by a
1418 hosted sandbox; it needs an API key. People on subscriptions use their own
1419 Claude Code session, which is a full participant.
1420- **The workspace pays.** A workspace buys AI credit by card and each
1421 agent run deducts the model at the provider's price plus the agent rate
1422 per million (weighted) tokens; on its own model key, only the agent rate,
1423 counted from the model proxy and the sandbox's own report. The billing service asks
1424 nothing of the others: the runner asks it before starting a sandbox and
1425 is refused when there is no credit, and the sandbox reports what its run
1426 cost with a token only it holds. Where no card processor is configured
1427 nothing is charged and agents stay limited to listed accounts.
1428- **Keys are secrets.** Stored in Cloudflare Secrets Store, injected into the
1429 sandbox for one pull request, never shown again.
1430
1431### Seeing a pull request through
1432
1433Assigning an issue is the only thing a person does until there is something
1434to merge. A pull request made by g1t goes through checks, a review
1435by another agent, revision when either finds something, and catching up
1436when `main` moves, without anyone pressing a button. It ends as ready to
1437merge, or as "needs you" with the reason: the checks still fail after two
1438revisions, a review could not be written, or a conflict could not be
1439resolved.
1440
1441The work service decides the next step from the pull request's state and
1442claims it in one statement, so a step is taken once. The runner asks on
1443every event that could change the answer (ready, pushed, checks finished,
1444review finished, `main` moved), and on a five-minute sweep for anything
1445missed, and carries the step out in a sandbox.
1446
1447A pull request does not have to be up to date with `main` to merge,
1448unless the repository's settings require it, as on GitHub. Merging one that
1449is behind brings it up to date first (a clean merge needs no model; an
1450agent resolves a conflict) and lands it when that push arrives. With the
1451requirement on, catching up is a step of its own and the checks run again
1452on the result.
1453
1454Each repository sets its own rules, on one settings page: whether its
1455default branch takes pushes at all, how many approvals a merge needs and
1456whether an agent's counts, whether failed checks can be overridden, whether
1457a second agent reviews, and how often an agent is sent back before a person
1458is asked. A pull request g1t opens follows the same rules as anyone's.
1459Pushes to a protected branch are refused in the git front end, with the
1460reason shown by git beside the branch.
1461
1462Merging is a person's decision unless the repository says otherwise. With
1463"merge automatically when ready" turned on in its settings, a ready pull
1464request lands by itself, attributed to `g1t`. That is the whole path from
1465an assigned issue to a commit on `main` with nobody in between. Required
1466human approval per path, and risk tiers, are still to come.
1467
1468### Routing for cost
1469
1470*Built (runner `route` in `services/runner/src/model-env.ts`).* The goal
1471is cost per merged change, not cost per request: a cheap attempt that
1472fails and is retried on the same model costs more than one that finishes.
1473
1474- **Tiers and catalogue.** `small` (Claude Haiku 5.5 since 2026-10-08,
1475 $0.10/$0.50 per million input/output up to 100k-token prompts, five
1476 times that above; it was Haiku 4.5 at $1/$5), `large` (Claude Sonnet 5.5, $2/$10) and `frontier`
1477 (Claude Opus 5.5, $4/$20). Models, names and list prices are data,
1478 never code: since 2026-10-08 billing's model catalogue
1479 (`gateway_models`, one row per model g1t can use) and staff's defaults
1480 in sudo, **Agents & models** (`model_defaults`: each tier's model, the
1481 harness's background model, the AI Gateway's first Claude, each job's
1482 starting tier and effort), read by the runner once a minute over
1483 `AGENT_ROUTING`, which is only the fallback when billing cannot be read.
1484 Catalogue prices are for estimates only; runs are charged what AI
1485 Gateway priced them at.
1486- **Keeping up with new models (built 2026-10-08).** The models service
1487 lists Anthropic's models (through the AI Gateway) and Workers AI's daily
1488 and on demand; a new id lands in the catalogue as `new`, priced from a
1489 maintained table of Anthropic's list prices or Workers AI's listing, or
1490 unpriced, and staff are emailed. Nothing routes to it, offers it or
1491 charges for it until staff approve it with its prices. A model a provider
1492 stops listing is `deprecated`; routing never sends work to a deprecated
1493 or retired model, falling back to the next model of the tier and saying
1494 so on the run. Customers keep Auto: the catalogue is staff's. See
1495 [BILLING_OPERATIONS.md](BILLING_OPERATIONS.md#the-model-catalogue).
1496- **Starting tier by job.** Catch-up, answering a question, and reviews of
1497 at most 10 files and 200 lines touching no sensitive path: small.
1498 Plans: small at high effort (Haiku 5.5 takes an effort level).
1499 Changes, revisions and other reviews: large. Reviews over 60 files
1500 or 3,000 lines: frontier. Labels: `architecture` frontier, `security` off
1501 small, `docs`/`documentation`/`typo` let changes and answers start small.
1502- **Escalation.** A failed (or guardrail-stopped) attempt at the same work
1503 goes one tier up; two in a row, frontier; a revision counts its rounds;
1504 a change left at low confidence sends the next attempt up.
1505- **Learning, per repository.** From the last 20 runs of the same kind:
1506 one tier down when the cheaper tier finished at least 90% of at least 5
1507 (never for sensitive or labelled work, never on a retry); one tier up
1508 when this tier failed at least half of at least 5. No new tables: it
1509 reads work's `agent_runs` (model, status, confidence).
1510- **Explained.** Every run's first step and session note is one line:
1511 *Used a fast model (Claude Haiku 5.5): small change, 3 files and 80
1512 lines.* Effort per kind of job (`effort` in `AGENT_ROUTING`: plan high,
1513 answer medium, update low) is sent as `CLAUDE_CODE_EFFORT_LEVEL` on
1514 g1t's tiers (never on a model the catalogue says takes none) and named
1515 in that line, with the catalogue's name for the model.
1516- **Chosen instead.** `model_routes` rows to g1t's models name `small`,
1517 `large` or `frontier`, or nothing for Auto (Integrations → Models).
1518 A workspace's own Anthropic key with no model named is routed by Auto
1519 too.
1520- **Measured.** `scripts/ops/routing-savings.mjs` replays tasks through
1521 the router offline, priced from the catalogue, against routing before
1522 Auto and against the frontier model for everything, net of failed
1523 attempts, with cost per merged change; `--live` reads billing's runs and
1524 counted tokens. On the bundled sample (13 tasks, assumed failures): Auto
1525 costs 7% less than the frontier model for everything and about 7% more
1526 per run than routing before it, but half as much per merged change,
1527 because it finishes the hard tasks the old routing gave up on. At
1528 current prices Opus 5.5 and Sonnet 5.5 cost the same per cache read, and
1529 cache reads are most of an agent run's tokens, so moving off the
1530 frontier model saves less than its list price suggests; the fast tier
1531 and fewer failed attempts are where the money is. Run `--live` monthly
1532 and after any routing change.
1533- **A cheaper route for the simplest jobs (designed, off).** A fourth tier
1534 on Workers AI through AI Gateway (an open model, billed on Cloudflare's
1535 invoice) for classification-sized jobs: commit messages, triage,
1536 summaries. Behind the same router as a tier with its own catalogue entry
1537 and `tasks` rules, off by default. It needs the proxy to translate the
1538 harness's Anthropic requests to the gateway's OpenAI-compatible
1539 endpoint (it already does for workspaces' own OpenAI-shaped providers)
1540 and a quality bar from the savings harness before any job moves to it.
1541
1542### Choosing the right agent automatically
1543
1544Because several agents can work on the same issue, every issue with more
1545than one pull request is an evaluation on real work. g1t records, per repo and per kind of issue, each
1546agent's win rate, cost and time. That produces a leaderboard, and a routing
1547policy: send each new issue to the agent that wins that kind most often,
1548start with the cheapest that is good enough, and escalate to a stronger one
1549when checks fail.
1550
1551## Talking: the inbox and channels
1552
1553Not a discussions forum. People and agents need one place to talk in real
1554time, and an app that feels like one on desktop and phone.
1555
1556**The inbox comes first.** Everything that needs a person or that they
1557follow, from people and agents: review requests, agent questions and
1558handoffs, failures, mentions, deploys. Read and unread, saved, done,
1559snoozed; ranked so what an agent is blocked on comes first; email digests
1560and push. It is the delivery layer chat needs too (who is told what, read
1561state, push), so building it first makes channels cheap.
1562
1563*Built:* the events service keeps it (`services/events/src/inbox.rs` and
1564`subscriptions.rs`, migrations `0005_inbox` and `0006_inbox_threads` on the
1565`g1t-events` database), writing items as events arrive from the bus; work's
1566`inbox_subject` says what each event names. Each person has one **thread**
1567per issue, pull request, workflow on a branch or deployment: new activity
1568brings it back unread with a count and its last 10 activities, and while it
1569is unread its most urgent severity is kept. Each item has a **reason**
1570(`agent`, `review_requested`, `assign`, `mention`, `ci_activity`,
1571`security_alert`, `state_change`, `author`, `comment`, `manual`,
1572`subscribed`). Who is told: `agent.asked` and `pull.stalled` (needs you,
1573closed again by `pull.resumed` and the like), `pull.review_requested`
1574(needs you, closed by `pull.review_request_removed`),
1575`issue.assigned`/`pull.assigned`, failed checks and workflows,
1576`deployment.failed` and a recovering `deployment.succeeded`, g1t's reviews
1577and finished changes, closes, reopens and merges to everyone subscribed,
1578and comments to the people mentioned and everyone subscribed. Never the
1579actor, never g1t. **Subscriptions**: authors, assignees and reviewers are
1580subscribed without a row; commenting or being mentioned subscribes; anyone
1581can subscribe, unsubscribe (still told of what is asked of them) or ignore.
1582**Watching** a repository: participating (the default), all, ignore, or
1583custom (issues, pulls, deployments, security); whoever creates a repository
1584watches it at their default, all activity unless they change it.
1585**Settings**: which reasons are also emailed (agent, review_requested and
1586mention by default) and the default watch for new repositories; email goes
1587through identity's `notify_by_email`, to a confirmed address only while the
1588person can still read the repository. **REST and MCP**: 14 operations under
1589`/notifications`, `/repos/:owner/:name/subscription` and
1590`/user/subscriptions` (scopes `notifications:read` and
1591`notifications:write`, in the Agent preset), and the `notifications` MCP
1592tool; never usable by g1t's own tokens. On the site: a bell in the top bar
1593opening a sheet with tabs (All, Needs you, Errors, Success, Info), Done,
1594Save, Snooze and Mark all read; `/inbox` with Saved, Done and a reason
1595filter; reasons and update counts on each card; a Notifications box on
1596issue and pull request pages; a Watch menu in the repository header;
1597Settings → Notifications; a Needs you card on mission control. Agent sits
1598beside the bell, disabled. Still to come: security alerts (the security
1599service publishes no event yet), email digests and push, Agent, and
1600channels.
1601
1602**Channels** (working name): workspace channels, direct messages and
1603threads, live.
1604
1605- Each channel is a Durable Object holding its WebSocket connections with
1606 hibernation, so idle channels cost nothing; history in D1, files in R2.
1607- Agents are members. `@g1t` in a channel starts work, answers, or
1608 posts a summary; agents post their questions and handoffs where people
1609 already are. A thread becomes an issue or an outcome in one action, and
1610 the agent's progress streams into that thread.
1611- Tied to the work: issues, pull requests, runs and deploys each have a
1612 thread; links unfurl into live cards (checks, agent step, preview).
1613 What a channel settles can become workspace memory, with its source.
1614- Apps: an installable PWA first (desktop and mobile, offline shell, Web
1615 Push), then native shells on the same API: Tauri for desktop (tray,
1616 deep links), React Native for iOS and Android (background
1617 notifications).
1618
1619GitHub-style Discussions are not planned: channels and threads on the
1620work replace them.
1621
1622## What GitHub ships today, and where g1t differs
1623
1624GitHub's Agent HQ and Copilot app give each agent session its own git
1625worktree and branch, list sessions in a mission-control view grouped by
1626project, and let a task be assigned to several agents so their output can be
1627compared. Underneath, the unit of work is still a branch and a pull request.
1628
1629| | GitHub | g1t |
1630| --- | --- | --- |
1631| 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 |
1632| Agent context | Lives in the app's session view | Stored with the repository and linked from each commit (why-blame) |
1633| 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 |
1634| Collisions between agents | Found as merge conflicts at the end | Flagged during the work (overlap radar) |
1635| Landing changes | One pull request at a time | A merge queue that lands the chosen one and closes the rest as superseded |
1636| Which agents | Those offered through a Copilot subscription | Any MCP client, plus hosted agents |
1637
1638## How agents connect
1639
16401. **Bring your own agent.** A remote MCP server at `mcp.g1t.sh` lets Claude
1641 Code (or any MCP client) list issues, claim one, get a clone URL and
1642 token, report progress and submit. Adding it is one command; sign-in is a
1643 browser OAuth flow with no token to paste. The `g1t` CLI installs Claude
1644 Code hooks that upload the session transcript as the agent works.
16452. **g1t's agent.** Assign an issue to g1t, or many issues at
1646 once, each to an agent of its own. g1t starts a sandbox for each
1647 (Cloudflare Containers), running a coding agent headless against its
1648 own pull request and fork.
16493. **API and CLI.** Everything above is available at `api.g1t.sh` and
1650 through `g1t`.
1651
1652## Public surfaces
1653
1654| Host | What it serves |
1655| --- | --- |
1656| `g1t.sh` | The site, git over HTTPS, git over SSH |
1657| `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 |
1658| `mcp.g1t.sh` | Remote MCP server over streamable HTTP |
1659
1660g1t is its own OAuth 2.1 authorization server: authorization code with PKCE,
1661dynamic client registration that stores nothing (a client id encodes its
1662own registration, so the open endpoint cannot be used to fill a database),
1663discovery metadata and rotating refresh tokens. Still to come: scopes
1664per resource (`repo:read`, `repo:write`, `issue:write`, `pull:write`).
1665MCP clients, the CLI (device flow) and third-party apps all use it. Access
1666tokens and SSH keys remain for git itself.
1667
1668### Workspace aliases (internal, built 2026-10-07)
1669
1670`g1t` is the product; `flagon-io` is Flagon, Inc., the organization that
1671builds it. So nobody mistakes one for the other, `g1t.sh/g1t` leads to
1672`g1t.sh/flagon-io`. That is a workspace alias: a name g1t's staff point at
1673a workspace, kept in identity's `workspace_aliases` (migration 0029, which
1674seeds `g1t`) by the workspace's id, so it follows renames. It is not a
1675customer feature and is not documented for users; staff add and remove
1676aliases on sudo's Aliases page, with a reason, in sudo's audit log. We may
1677give other companies one for a trading name the same way.
1678
1679An alias is resolved wherever an old slug is (identity's `resolve_slug`),
1680so it costs only the not-found path: site pages 301 to the same page under
1681the workspace, the API and MCP run the call again under its slug, package
1682registries 301, and git over HTTPS is answered in place
1683(`resolve_alias`), because pushes do not follow redirects. An alias is
1684never a route, a username or a workspace's slug, and nobody can register
1685it while it exists. `@g1t` stays g1t's agent: mentions link to how the
1686agent works, never to `/g1t`.
1687
1688## Architecture
1689
1690| Component | Language | Runs on | Responsibility |
1691| --- | --- | --- | --- |
1692| `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. |
1693| `services/identity` | Rust | Worker + D1 | Accounts, workspaces and memberships, sessions, SSH keys, access tokens, device sign-in, OAuth codes and grants |
1694| `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. |
1695| `services/work` | Rust | Worker + D1 | Issues, pull requests, comments, sessions; later a Durable Object per repo for the landing queue and live state |
1696| `services/billing` | Rust | Worker + D1 + Stripe | Each workspace's agent credit: payments, the ledger of every run, and the gate on starting one |
1697| `services/events` | Rust | Worker + Queues + D1 | The event bus: durable log, and one queue per subscribing service |
1698| `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 |
1699| `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 |
1700| `apps/web` | TypeScript | Worker | Server-rendered site. Holds no data; calls services over RPC. |
1701| `apps/docs` | TypeScript | Worker (static) | Documentation and the API explorer |
1702| `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 |
1703| `crates/sshd` | Rust | Container | Git over SSH, bridged to Artifacts |
1704| `crates/merged` | Rust | Container | Trial merges, conflict matrix, landing merges (needs real git; the Artifacts binding is read-only) |
1705| `crates/core` | Rust | native and WASM | pkt-line, packfile and diff code shared by the above and by the Worker |
1706| `crates/g1t` | Rust | user's machine | CLI: auth, SSH proxy, Claude Code hooks, issues and pull requests |
1707
1708Storage: Artifacts for repositories (one fork per pull request), D1 for accounts
1709and metadata, R2 for session transcripts and logs, Durable Object SQLite for
1710per-repo coordination state.
1711
1712How the services fit together:
1713
1714- **Each service is its own Worker with its own database.** It deploys,
1715 scales and fails on its own. Callers reach it through a typed RPC binding
1716 to the interface in `packages/contracts`.
1717- **Expected failures are values.** Every call returns a `Result`, so "not
1718 found" or "forbidden" crosses a service boundary as data.
1719- **Side effects travel as events.** A service publishes what happened
1720 (`git.push`, `issue.opened`, `pull.merged`, …) to the bus and does not
1721 call other services to react. Each subscriber consumes from its own queue.
1722 Timelines, webhooks and automations read the same stream, which is what
1723 lets something like GitHub Actions be built on top.
1724- **Every read takes the viewer.** Authorization is decided inside the
1725 service that owns the data, not by its callers.
1726
1727The Workers runtime scales request handling on its own, so the edge layer
1728stays in TypeScript. Rust is used where there is real computation or a real
1729protocol to implement.
1730
1731## Languages
1732
1733The site is TypeScript. Everything behind it is Rust, compiled to
1734WebAssembly for Workers and natively for containers and the CLI. Identity, repos, work, events and the API are all Rust. The one exception
1735is the Worker that starts sandboxes, because Cloudflare's Containers
1736library is TypeScript. Rust services speak a
1737small JSON protocol over service bindings (`POST /rpc/<method>`), with the
1738types in `crates/contracts`.
1739
1740## Identifiers
1741
1742Every id is a [TypeID](https://github.com/jetify-com/typeid): a prefix naming
1743the kind of thing, then a UUIDv7 in lowercase base32, such as
1744`pr_01jb2k7x9hfq0b3zj0f5s2m8ra`.
1745
1746- The prefix makes an id self-describing and stops ids of different kinds
1747 being mixed up.
1748- Ids sort by creation time as plain strings. In SQLite (D1 and Durable
1749 Objects) that keeps inserts at the end of the primary-key index instead of
1750 scattering them, and gives time-ordered paging for free.
1751- The suffix decodes to a standard UUIDv7 for any system that wants one.
1752- Ids are made by the service that creates the record, not by the database,
1753 so they work across services and can be assigned before a write.
1754
1755## Events at scale, and audit
1756
1757The current event log is a single D1 database. That is fine for a
1758prototype and wrong for the target: D1 is one writer and 10 GB. The design
1759for volume splits storage by how the data is read.
1760
1761| Tier | Store | Holds | Read by |
1762| --- | --- | --- | --- |
1763| Hot | A Durable Object per repository, with SQLite | Recent events for that repo | Timelines, live pages over WebSocket |
1764| Complete | Cloudflare Pipelines into R2 as Apache Iceberg | Every event, forever, partitioned by day and workspace | Analytics, standups, "ask", export |
1765| Audit | The same R2 store, under object lock | Who did what, from where, with which credential | Compliance, investigation |
1766
1767- **No single hot database.** Each repository's recent events live with that
1768 repository, so load spreads across as many objects as there are repos.
1769- **The complete record is files, not rows.** Iceberg on R2 has no practical
1770 size limit and is queried with SQL.
1771- **Audit is a property of every event.** The envelope carries the actor
1772 (person, agent, token or system), the credential used, the request id and
1773 the source address. Audit entries for a workspace are hash-chained, so a
1774 removed or altered entry is detectable, and are written under a retention
1775 lock.
1776- **Delivery is at least once.** Consumers are idempotent on the event id.
1777
1778## Accounts and forge basics
1779
1780- Registration with email verification, sign-in, forgot password (Cloudflare
1781 Email Sending), Turnstile on public forms.
1782- GitHub sign-in, SSH keys, access tokens, active sessions.
1783- Profiles, public and private repositories, repository search (D1 full-text).
1784- Rendered README, syntax highlighting, commit history, diffs.
1785- Transferring a repository between workspaces (by id: its git store key
1786 never moves; every service follows `repo.transferred`; old paths redirect
1787 until reused) and deleting an empty, settled workspace (its slug is
1788 tombstoned, never reissued except to the person whose username it is).
1789- Access: five repository roles (Read, Triage, Write, Maintain, Admin;
1790 the capability table follows GitHub's repository roles, 2026-10-08:
1791 branch protection and rulesets are Admin, labels and milestones are made
1792 with Write and applied with Triage, security alerts are Write), a
1793 workspace base permission (Read for new workspaces), the creator of a
1794 repository given Admin on it, outside collaborators and invitations.
1795 Membership as GitHub's organizations have it (2026-10-08): owners and
1796 members, promote and demote, transfer ownership, leave, a last-owner
1797 guard; billing manager and security manager on top of member; member
1798 privileges (who creates public and private repositories, whether
1799 repository admins change visibility, delete and transfer, and invite
1800 outside collaborators); two-factor authentication (TOTP and recovery
1801 codes) and a workspace policy that requires it, holding non-compliant
1802 people out until they turn it on. Every membership change, token, SSH
1803 key, OAuth grant and two-factor change is in the audit log. Teams are built on it (2026-10-07): visible
1804 or secret, nested up to 8 levels (child teams inherit their parents'
1805 roles), run by maintainers and owners. A team's role on a repository is a
1806 `repo_grants` row whose principal is the team, which identity resolves
1807 into the same `RepoGrant`s on each person, so `access::can` needs nothing
1808 new: the highest role wins. `@workspace/team` mentions tell the team's
1809 people; a team asked to review either asks everyone or picks people by
1810 round robin or load balance.
1811- CODEOWNERS, read in both conventions (single-section, and sections with
1812 approval counts, optional sections and default owners) from the first of
1813 `.g1t/`, `.github/`, the root, `docs/` and `.gitlab/`. Owners are asked to
1814 review, the `g1t / codeowners` status lints a changed file, and branch
1815 protection's "Require review from code owners" holds merges, for people,
1816 agents and the queue alike, until each owning rule is approved.
1817

1837## Running g1t yourself
1838
1839g1t.sh runs on Cloudflare, and that does not change. The core is MIT and
1840must also run on anyone's own machine with `docker compose up`. A free
1841core people can self-host is what makes paid hosting worth trusting.
1842Self-hosting never makes hosted worse: hosted code paths keep their
1843behaviour, and a self-hosted adapter sits beside the hosted one. The
1844inventory of every Cloudflare dependency, the design and the risks are in
1845[SELF_HOSTING.md](SELF_HOSTING.md).
1846
1847The approach: the Workers stay Workers, and self-hosted they run in
1848workerd, the open-source Workers runtime. D1, KV and Queues are SQLite on a
1849volume, with the same migrations. Cloudflare-only bindings are replaced
1850by stand-ins:
1851
1852- Artifacts becomes bare repositories served by `git http-backend`;
1853- Email Sending becomes SMTP, through Mailpit;
1854- services that are off answer "off" instead of failing.
1855
1856| Phase | Scope | Estimate |
1857| --- | --- | --- |
1858| 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 |
1859| 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 |
1860| 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 |
1861| 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 |
1862
1863## The submission
1864
1865- **g1t is built on g1t.** This repository is hosted on g1t.sh, its features
1866 are opened as issues and built by racing agents, and it deploys from
1867 Artifacts through Workers Builds. The history is the proof.
1868- **The demo follows one story.** A brief becomes a project; twelve issues
1869 fan out to dozens of agents; agents notice each other, hand off, and
1870 resolve a conflict; reviewers triage; the queue lands everything on
1871 `main`; why-blame explains a line; the portfolio shows where it all
1872 stands. Then the same thing at a thousand agents.
1873- **Judges can try it in a minute.** Open registration on g1t.sh, one-click
1874 import of a GitHub repo, one command to connect Claude Code, a seeded demo
1875 workspace, and a single deploy command for running their own copy.
1876- **The formats are open.** The commit trailers, session format and runner
1877 contract are published so other tools can interoperate.
1878
1879## Build order
1880
1881What is left is ordered by how much it shows the point above, not by forge
1882parity. Forge basics are done well enough; each item below should make the
1883demo's story stronger.
1884
1885Done from this list: the outcome page (a plan's issues as a live graph with
1886cost and a feed of what happened), coordination you can see (agents' issues
1887and comments stand out in the feed; agents hold g1t's tools through a token
1888scoped to one repository), steering a running agent (messages delivered
1889between steps, and at the end), and recording sessions from anyone's own
1890Claude Code (`curl -fsSL https://g1t.sh/install/claude.sh | sh`). Integrations are
1891in: a workspace's own model provider (Anthropic or any Anthropic-compatible
1892endpoint, reached through a model proxy so no sandbox holds a key; its
1893runs pay only their sandbox time), alerts from Sentry, Datadog and signed webhooks
1894that open one issue per problem and can start an agent, and Jira and Linear
1895tickets that agents read, people import, and that hear back. Racing a
1896set number of agents on one issue is dropped: choosing how many agents to
1897use is not something people should have to do.
1898
18991. ~~**Handoffs and questions between agents** as states on the outcome
1900 page.~~ Done: questions and handoffs show as waiting, read, answered,
1901 taken on or declined; since 2026-10-03 an agent asked while it is not at
1902 work is woken to answer, where before the question waited forever.
19032. **Upkeep agents** (above): dependency updates, secret scanning,
1904 vulnerability alerts, code scanning, the security page. No new
1905 infrastructure.
19063. **Deployments on `g1t.page`** (above): previews per pull request,
1907 production on merge, the reviewer agent checking the preview.
19084. **The large run, building 2 and 3.** About 20–30 issues on g1t itself,
1909 built by agents and landed through the queue, for the video: g1t built
1910 on g1t.
19115. **Polish for judges trying it in a minute:** a seeded demo workspace, the
1912 empty states, and the first-run path from sign-up to an outcome landing.
1913
1914Earlier items still open, after those:
1915
19161. Deleting a branch once its pull request merges; risk tiers. (Approval
1917 rules per path are in, as CODEOWNERS.)
19182. Event storage per the design above: per-repo hot log, Iceberg on R2,
1919 hash-chained audit.
19203. CLI with Claude Code hooks to record sessions automatically.
19214. Reviewing and catching up automatically, by policy; required reviews;
1922 risk tiers.
19235. Compare view, proof bundles; handoff between agents.
19246. Projects, mission control, steering; why-blame, digest, timeline.
19257. Context hub, portfolio; automations and integrations (Sentry first).
19268. SSH; bot protection; own keys, endpoints and runners.
19279. Large run (100+ agents across many issues), hardening, demo.
192810. Passkeys (WebAuthn) as a second factor and for signing in: feasible on
1929 Workers (P-256 and RS256 verification in Rust, or WebCrypto), next
1930 after TOTP. Then fine-grained tokens, deploy keys and package access.
1931
1932Later: code search, mirroring to GitHub, SSH
1933on port 22 without the CLI proxy (needs the Workers inbound TCP private
1934beta).
