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.** Viewer, commenter, planner, approver: a person can plan and
298 approve work without ever cloning a repo.
299
300## The macro view
301
302The hierarchy above a single repo:
303
304| Level | What it is |
305| --- | --- |
306| **Workspace** | A company or team: its people, repos, agents, budget and policies. |
307| **Initiative** | A business outcome with an owner and measurable results, e.g. "move billing to usage-based pricing". Spans any number of repos. |
308| **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. |
309| **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. |
310
311How it feeds up, and what is built:
312
313- **A workspace is the unit everything belongs to.** Repositories, people,
314 access tokens, and later projects, budgets and policies are the
315 workspace's, never a person's. An account owns nothing; its first step
316 after confirming its email is creating a workspace, and the site sends it
317 there from wherever it was going.
318- **One namespace.** Usernames and workspaces share one set of names, as on
319 Docker Hub and npm. A username is reserved for its owner's workspace, so
320 `g1t.sh/<name>` never means two things.
321- **The workspace page is the roll-up.** `g1t.sh/<workspace>` shows its
322 repositories with their open issues and pull requests, and the pull
323 requests in progress across all of them. Projects and initiatives will
324 roll up to the same page. Its own pages live under `/<workspace>/-/`
325 (people, access tokens, settings), which no repository can be named.
326- **Workspace access tokens instead of service accounts.** A workspace has
327 tokens of its own, in the same table and code path as personal ones. One
328 acts as the workspace, with a member's rights in that workspace only,
329 records who made it and when it was last used, and keeps working when
330 that person leaves. CI, integrations and automations use these.
331
332### Portfolio
333
334One page answers "where is the business" across every initiative:
335
336- **Health** per initiative: on track, at risk, or blocked, derived from
337 facts (checks passing, issues stalled, questions waiting on a person),
338 not self-reported.
339- **Progress** as measurable results: required checks passing, issues
340 merged out of planned, and the trend since the start.
341- **Forecast** from actual throughput: at the current rate, when the
342 remaining issues land.
343- **Spend** in tokens and dollars against a budget, per initiative.
344- **Waiting on people**: every decision or approval a person owes, by name.
345- **Roadmap**: initiatives laid out as now, next, later, with optional
346 time-boxed cycles for teams that work in sprints.
347
348### Status without asking
349
350- **Standup.** An agent writes a daily report per initiative and one for the
351 whole workspace: what merged, what changed direction, what is at risk and
352 why, what needs a person. Delivered by email or webhook.
353- **Ask.** A question box over the full event log and all sessions: "what
354 happened on the billing migration since Monday?" answers with links to the
355 sessions and commits behind each claim.
356
357### Long-running agents
358
359Work that runs for days needs supervision that does not depend on someone
360watching.
361
362- **Checkpoints.** A long pull request reports milestones against its issue, so
363 progress is visible before anything merges.
364- **Stall and drift detection.** A pull request with no meaningful progress, or
365 whose changes have wandered away from its issue, is flagged and can be
366 stopped or re-briefed automatically.
367- **Budgets.** Hard limits on spend and time per pull request, project and
368 initiative.
369
370### Context hub
371
372Agents working across repos and days need context that outlives any one
373session and reaches beyond the code. The context hub is one place an agent
374asks, whatever the source.
375
376| Source | What it holds | How it gets there |
377| --- | --- | --- |
378| **Memory** | Decisions, conventions, gotchas, facts about systems | Written by agents and people in g1t |
379| **Code and sessions** | The repos, and the reasoning behind every change | Already in g1t |
380| **Connected sources** | Jira and Linear tickets, Notion and Confluence pages, Google Drive documents, Slack threads, Sentry issues | Connectors, authorised per workspace |
381
382How it behaves:
383
384- **One search.** An agent asks a question and gets ranked results across
385 all sources, each labelled with where it came from, who wrote it, and how
386 fresh it is.
387- **Connected sources stay where they are.** g1t indexes them for search and
388 fetches the current version when an agent opens one. The external system
389 remains the source of truth, and a link placed on an issue ("see
390 JIRA-482", a Notion URL) is pulled into the agent's starting context.
391- **Permissions carry over.** A connector only exposes what the connecting
392 account can see, and a workspace admin chooses which spaces, projects or
393 channels are included.
394- **External content is untrusted.** A ticket or page can contain text meant
395 to manipulate an agent. It is marked as reference material, never treated
396 as instructions.
397- **Documentation is separate.** Context is what agents know; documentation
398 is what people read, and it is generated from context and code.
399
400Memory is the part of the hub that g1t owns and agents write to:
401
402- **Memory is written freely.** Any agent or person adds an entry with one
403 call: a decision, a convention, a gotcha, a fact about a system. No review
404 gate. Each entry records who wrote it, from which session, and when.
405- **It is still a repository.** Each workspace has a memory repo in
406 Artifacts, so every write is a commit: versioned, attributable, and
407 revertible.
408- **It is kept healthy by an agent.** A consolidation agent merges
409 duplicates, retires entries that newer ones contradict, and flags
410 conflicts it cannot settle. People can pin an entry (agents may not change
411 it), correct it, or retract it.
412- **Agents read it.** Every session starts with the context relevant to its
413 issue, found by search, and can query more through MCP.
414- **Updates are events.** A memory write or a change in a connected source
415 is an event, so "when context changes, update the affected docs" is an
416 automation, on by default.
417- **It is scoped inside the workspace.** Some context applies to the whole
418 workspace, some to one initiative, project or repo, so an agent gets what
419 applies to its work.
420- **It never crosses workspaces.** A workspace is the isolation boundary: its
421 context, sessions and private repos are invisible to every other
422 workspace, and an agent's token is bound to one workspace.
423
424## Working in g1t
425
426- **Mission control.** The signed-in home page: every running session, every
427 issue waiting on a decision, and what merged, across all repos.
428- **Outcomes.** Group issues across repos toward one result and track how
429 many are open, racing, or merged. (What [Projects](#projects) means is
430 below.)
431- **Steering.** Send a message to a running pull request, or to all pull requests on an
432 issue at once, without stopping them.
433- **Automations.** Rules that start work without a person (next section).
434
435## Automations and integrations
436
437> **2026-10-03:** g1t's own `.g1t/automations` format was built and then set
438> aside at the user's request ("let's just copy GitHub Actions on that for the
439> time being"). Automation on g1t is GitHub Actions workflows in
440> `.g1t/workflows/`; the format below is kept for later.
441
442An automation is **when** an event happens, **if** conditions hold, **do**
443something. They are defined as files in the repo (`.g1t/automations/`), the
444way GitHub Actions workflows are, and can also be built in the UI.
445
446### Events that can trigger one
447
448| Source | Examples |
449| --- | --- |
450| Git | push, merge, check failed, `main` moved |
451| g1t | issue opened, pull request stalled, context updated, handoff declined, budget reached |
452| Time | cron schedule |
453| Integrations | Sentry issue, PagerDuty incident, Linear or Jira ticket, Slack message or mention, GitHub issue, Stripe event |
454| Anything else | a signed generic webhook, or an email to a per-repo address |
455
456**Actions**: open an issue (optionally assigning N agents to it), message
457a running pull request, update documentation, notify, call a
458webhook, write back to the source system.
459
460**Example: Sentry.** A new production error arrives. The automation opens an
461issue labelled `bug`, with the stack trace, release and frequency in its
462description. Why-blame
463finds the session that wrote the failing line, so the fixing agent starts
464with the original reasoning. When the fix merges, g1t comments on the Sentry
465issue and resolves it.
466
467### Rules every automation obeys
468
469- **Deduplication.** The same Sentry issue firing 500 times maps to one
470 issue.
471- **Limits.** Concurrency and budget caps per automation.
472- **Loop protection.** Work started by an automation cannot retrigger the
473 same automation without a person in between.
474- **External input is untrusted.** A webhook payload can contain text written
475 by an attacker. Agents started by external events run with reduced
476 permissions and cannot merge without the repo's approval rule passing.
477
478**Checks** are the other half of what GitHub Actions does: build and test
479commands declared in `.g1t/checks.yaml`, run in sandboxes on every pull request
480and on every combined state in the landing queue.
481
482### Docker in workflow jobs (built 2026-10-08)
483
484> **2026-10-08:** "Why didn't we give CI docker then? We need GitHub
485> Actions functionality maxxed baby but with all the good good security
486> etc." The trigger: `deploy.yml`'s runner-image job needs `docker build`
487> and `docker push`, and failed on hosted runners.
488
489**What Cloudflare Containers allow** (their FAQ, updated 2026-10-05, and
490the Docker-in-Docker guide and example it links):
491
492- Docker runs inside a container: `docker:dind`, with `dockerd` as
493 **root**. A rootless Engine does not start there.
494- **No iptables**: `--iptables=false --ip6tables=false`, or the Engine
495 fails setting up its rules. Containers with the `durable_object`
496 scheduling policy (ours: each sandbox is a Durable Object's) cannot turn
497 IP forwarding on either: `--ip-forward=false`, or the Engine exits.
498- So **a bridge network has no way out**: the guide's answer is
499 `--network=host` for `docker run` and `docker build`, which gives
500 containers the outer container's network.
501- Built images and containers are lost when the sandbox stops.
502
503**What was found by trying** (Docker Engine 29.8.2 in a privileged
504container standing in for a sandbox, with the same flags):
505
506- `--bridge=none` makes BuildKit's `RUN` steps fail outright ("network
507 bridge not found"); with the default bridge they run with no route out.
508 Containers default to the bridge too. The default bridge is created
509 fine without iptables, as the FAQ's own example relies on.
510- The overlay snapshotter does not work on an overlay root filesystem, and
511 the containerd image store does not fall back by itself: the Engine
512 starts, then every container fails to mount. Whether a sandbox's disk
513 takes overlays is not documented, so the runner tries a mount first and
514 uses `native` (plain copies) when it fails. `vfs` is not a name the
515 containerd store accepts.
516- `--cpus` and `--memory` need cgroup v2 controllers handed down from a
517 cgroup with no processes, which `docker:dind`'s entrypoint does and a
518 plain `dockerd` does not.
519- A `runc` earlier on the Engine's `PATH` is used both for containers (via
520 containerd's shim) and by BuildKit's executor, with the bundle's
521 `config.json` written before it runs. BuildKit's bridged steps carry
522 libnetwork's `libnetwork-setkey` prestart hook; `RUN --network=none`
523 does not.
524- Buildx skips `type=gha` caches when the job has no GitHub cache service,
525 and the build succeeds without one.
526- Registries' layer hosts: Docker Hub sends layers from
527 `production.cloudfront.docker.com` (and `production.cloudflare.docker.com`),
528 Quay from `cdn0N.quay.io`, Microsoft's from regional
529 `*.data.mcr.microsoft.com`, public ECR from a CloudFront host;
530 `mirror.gcr.io` serves its own.
531
532**What was built** (`crates/runner/src/docker`, `actions/containers.rs`):
533
534- **One Engine per job, started lazily.** The runner listens on
535 `/var/run/docker.sock` itself and starts `dockerd` (root, the flags
536 above, containerd image store, `mirror.gcr.io` first for Docker Hub) on
537 the first connection, or when the job has `services:` or `container:`.
538 A log line says it started and how long it took.
539- **Containers on the job's network.** The socket is an API proxy: a
540 container that asks for a bridge or user network gets `host`; its names
541 (container name, aliases, Compose service, links) resolve to 127.0.0.1
542 in later containers (`ExtraHosts`) and in the job's steps
543 (`/etc/hosts`); `-p 8080:80` is forwarded; `docker inspect` reports the
544 ports as published; `network connect` adds aliases. Sharing the job's
545 network is also what keeps the guardrails on every container: the
546 egress Worker sees their traffic as the job's.
547- **A `runc` shim.** The runner binary, as `runc`: BuildKit steps bound for
548 a bridge lose the network namespace and the libnetwork hook (so they use
549 the job's network); in a guarded job every container (run, exec, build
550 step) gets the egress certificate at `/dev/g1t-egress` and the
551 variables that point tools at it. `/dev` is the container's own tmpfs,
552 so none of it lands in a layer; checked by saving a built image.
553- **Job features:** `services:` (pull, credentials, health waits, logs at
554 the end, `job.services.*`), `container:` (steps and JavaScript actions
555 through `docker exec`, Node mounted from the runner, Alpine falls back to
556 running actions beside it), `docker://` steps and Dockerfile actions in
557 GitHub's `/github/*` layout, `docker/setup-buildx-action` answered
558 natively (the job's Engine is the builder), sign-in to g1t's registry
559 with the run's token.
560- **Kill switch:** the runner Worker's `DOCKER` var (`off`).
561
562**Rejected:** rootless Docker or BuildKit (does not start in Containers);
563Podman or buildah with `vfs` (no better networking, less compatible, slow);
564a standalone `buildkitd --oci-worker-net=host` as the default builder
565(images not in the Engine's store, so `FROM` a just-built image and
566`docker run` of a build fail without `--load` round trips); a `docker` CLI
567wrapper adding `--network=host` (misses Compose, SDKs and testcontainers,
568which speak the API).
569
570**Not yet:**
571
572- Seen on Cloudflare itself: whether a sandbox's disk takes overlays,
573 `--privileged`, and the first deploy's pull of the base from
574 `registry.cloudflare.com` (its layer host may need a workflow-only line).
575- `type=gha` build caches backed by g1t's Actions cache.
576- Multi-platform builds (QEMU's `binfmt_misc` in a sandbox).
577- Docker for agents and checks, not just workflow jobs.
578- `runner-base.yml` on g1t's machines: the base's apt step needs
579 `Acquire::https::CAInfo` pointed at the egress certificate first.
580- A deploy that appends the runner binary as a layer through the registry
581 API, with no Docker and no 3 GB pull.
582
583Agents can also reach integrations directly: an agent definition lists MCP
584servers (Sentry, Linear and so on) it may use while working.
585
586### Workflows: the toolkit, OIDC and artifacts
587
588> **2026-10-08:** built so that workflows that deploy, cache and pass files
589> run unmodified.
590
591- **The toolkit's services.** Every job gets `ACTIONS_RUNTIME_TOKEN` (a
592 JWT whose `scp` names its run and job, signed with a key derived from
593 the job's own token, so nothing new is kept), `ACTIONS_RESULTS_URL`,
594 `ACTIONS_CACHE_URL` and `ACTIONS_CACHE_SERVICE_V2`. The API answers the
595 cache's Twirp service (v2) and its older REST protocol, the artifact
596 Twirp service, and the signed blob links they hand out (a subset of
597 Azure Blob's protocol mapped onto R2 multipart uploads), from the same
598 cache and artifact rows g1t's own runner uses. As the clients' source
599 reads, `@actions/cache` and `@actions/artifact` treat any server
600 but github.com as GitHub Enterprise Server, so the cache client speaks
601 the older protocol and the artifact client refuses to run. g1t's runner
602 therefore keeps handling `actions/upload-artifact`, `download-artifact`
603 and `upload-artifact/merge` itself; the Twirp artifact service is there
604 for clients that do not check.
605- **OIDC.** The issuer is `{API}/actions/oidc`, the API's own host, with
606 discovery, JWKS (RFC 7638 `kid`s, a previous key published while
607 rotating) and a token endpoint for `core.getIDToken`. Claims follow
608 GitHub's. A job gets one only when its permissions (or its workflow's)
609 give `id-token: write`, and never for an untrusted run. The permission
610 check reads only `id-token` (`services/actions/src/runtime.rs`,
611 `id_token_permitted`), the seam for the full `permissions:` model.
612- **Artifacts** moved from KV to R2 (`a/` in the cache bucket), with rows
613 in the actions service: numeric ids, 5 GiB each and 10 GiB a run,
614 zipped by the runner, `retention-days` up to the repository's setting
615 (1 to 90, 14 by default), `overwrite`, `compression-level`, patterns,
616 merging and other runs of the same repository. The REST artifacts API and
617 the `workflow` tool's artifact actions follow GitHub's shapes; the run's
618 page lists them with size and expiry, with download and delete. Their
619 storage is charged with the cache's.
620- **Later:** the toolkit's older artifact protocol (`upload-artifact@v3`
621 inside other actions), downloads from other repositories, and npm
622 trusted publishing, which depends on npm accepting g1t's issuer.
623
624## A repository that maintains itself
625
626> **2026-10-04:** the user asked for Dependabot, GitHub Advanced Security and
627> Vercel-style deployments, "so you're not having to maintain shit and you're
628> just pushing up agents that are delivering work consistently".
629
630GitHub reports problems and leaves the fix to you. In g1t, an agent opens an
631issue for each problem, writes the fix, runs its checks, links a preview and
632lands it through the queue. People only decide.
633
634### Upkeep agents
635
636- **Dependency updates.** The file is `dependabot.yml` version 2, read from
637 the default branch at `.g1t/dependabot.yml` (or `.yaml`), then
638 `.github/dependabot.yml` (or `.yaml`); `.g1t/` wins when both exist, and
639 an imported repository's file works unchanged. Every option is read and
640 checked, each problem reported with its line and key on the Security page
641 and as the `g1t / dependabot.yml` status on pull requests that change the
642 file; a file with problems is not acted on.
643 - **Built (2026-10-07):** version updates for npm, cargo, gomod and pip:
644 schedules (all intervals, cron and natural phrases, time zones, a
645 picked time per repository), allow, ignore, cooldown (3 days by
646 default), groups (including across directories and `group-by`),
647 versioning strategies, open-pull-requests-limit, commit-message,
648 branch names, rebase-strategy, assignees, reviewers, private
649 registries filled from workflow secrets (npm, cargo, Go proxy, Python
650 index), and the `@g1t` comment commands. Pull requests come from g1t
651 with an `updated-dependencies` commit record and land through the
652 required checks; one that fails them is closed and becomes a
653 "needs code changes" issue assigned to g1t.
654 - **Security updates follow the same file:** ignore (and comment
655 ignores), allow names, `applies-to: security-updates` groups,
656 commit-message, assignees, reviewers, labels and milestone. Cooldown
657 and the open pull request limit do not apply. The Security updates
658 switch still turns them on and off.
659 - **Labels, milestone and target-branch** are applied to version
660 updates: `dependencies` and the ecosystem's label by default, missing
661 labels created; `target-branch` updates are made from that branch and
662 merge into it.
663 - **Not done yet:** one pull request for a multi-ecosystem group
664 (it opens one per ecosystem); registries that sign in with OIDC;
665 updating vendored copies; and version updates for the other
666 ecosystems (bundler, composer, docker, github-actions, gradle, maven,
667 nuget, terraform, uv and the rest are read and checked only).
668- **Secret scanning.** Pushes are scanned for known token formats. A push
669 that adds a secret is refused with the file and line; one already in
670 history opens an issue to rotate it and remove it.
671- **Vulnerability alerts.** Dependencies are matched against the OSV
672 database. Every alert links to the issue and pull request fixing it.
673- **Code scanning.** A reviewer agent reads each pull request's diff for
674 security problems and leaves findings as review comments with a
675 suggested fix. Findings on `main` open issues.
676- **A security page per repository** lists alerts, secrets and findings,
677 with the agent work on each, like GitHub's Security tab.
678
679All of these are event sources for the existing issue → agent → checks →
680queue pipeline; they need no new kind of work.
681
682### The security suite (built 2026-10-07)
683
684GitHub Advanced Security's depth, in g1t's shape (services/security,
685`g1t_contracts::security_suite`, docs `guides/security/*`):
686
687- **Secret protection.** Custom patterns (repository and workspace; Rust
688 `regex`, linear time, size-limited; test strings; dry run over the
689 default branch) used by push protection, `commit_file` and history
690 scans. Bypass with a reason (false positive, used in tests, will fix
691 later), recorded on the alert and in the audit log; delegated bypass
692 (requests reviewed by owners and repository admins, through the inbox).
693 Validity checks for GitHub, GitLab, Stripe, Slack, npm, OpenAI,
694 Anthropic and SendGrid tokens, made by the repos service, which reads the
695 landed secret again: the value never leaves it except to the issuer. AWS
696 keys (need their secret key to sign) and webhook addresses (would post)
697 are the extension points left (`g1t_scan::validity::check_for`).
698- **Code scanning.** SARIF 2.1.0 uploads → alerts with fingerprints (tool
699 partial fingerprints first), fixed when no longer reported; pull request
700 uploads → line comments and the `Code scanning` commit status, gated by a
701 per-repository threshold and required like any check. Starter workflow:
702 a scanner per language present, each uploading its own category: Bandit
703 (Python), gosec (Go), ESLint + eslint-plugin-security with the SARIF
704 formatter (JS/TS), Clippy + clippy-sarif (Rust); all install from the
705 registries the runner's egress already allows. Semgrep's registry rules
706 and the Opengrep rules fork are not usable in a paid feature, so neither
707 is used. "Fix with g1t" opens an issue and runs the agent.
708- **Supply chain.** Dependency graph (direct/transitive where the lockfile
709 says, npm licenses), SPDX 2.3 SBOM, `Dependency review` status on every
710 pull request (OSV severity threshold, license deny list, summary comment).
711- **Overview.** Workspace totals, opened/closed, a daily snapshot trend,
712 coverage, repositories most in need first.
713- **Paid.** The Security and quality activation on private repositories;
714 free on public ones; the free core (secret scanning, push protection,
715 vulnerability alerts, security updates, dependency graph) free everywhere.
716
717Not built yet:
718
719- **The reviewer agent as an analysis source.** g1t's reviewer reads each
720 pull request's diff (`agent_review`), but its findings are review
721 comments, not SARIF. Next: have it emit SARIF for the security issues it
722 finds and upload them as the tool `g1t review`, so they become alerts and
723 count toward the Code scanning check.
724- **Repository security advisories.** Private advisories, draft →
725 published, with affected versions (ranges per ecosystem), severity and a
726 CVSS vector, credits, and a private fork (a `g1t/advisory/GHSA-…` working
727 copy only the advisory's collaborators can see) for the fix, merged into
728 the default branch when the advisory publishes. Published advisories
729 should feed the OSV-shaped data other g1t repositories' vulnerability
730 alerts read. CVE requests are out of scope. Needs: an `advisories` table
731 per repository, a collaborator list per advisory, the private-fork
732 visibility rule in repos, and an Advisories page on the Security tab.
733- **SARIF upload as a background job.** Uploads are read in the request
734 (10 MB encoded, 40 MB unzipped, 5,000 results); larger ones need a queue.
735
736### Deployments
737
738- **A preview for every pull request**, at
739 `<pr>--<repo>--<owner>.g1t.page`, linked on the pull request and updated
740 on each push. `main` deploys to `<repo>--<owner>.g1t.page`, and a
741 repository can add its own domain.
742- **On g1t.page, not g1t.sh,** so customer code never shares cookies or an
743 origin with the site people sign in to.
744- **Built on Workers for Platforms.** Each deployment is a user Worker in a
745 dispatch namespace; one dispatch Worker on `*.g1t.page` routes to it. The
746 build runs in the same runners as Actions. Static sites and Workers apps
747 first; container apps and databases later.
748- **Agents use the preview.** The reviewer agent opens the preview in a
749 browser, takes screenshots of what changed and attaches them to its
750 review, so an approver sees the result without reading the diff.
751- **Environments.** Preview, production and their secrets; deploy history
752 and one-click rollback.
753- **Scale to zero.** An idle branch costs neither g1t nor the customer
754 anything: a Worker runs, and is billed, only while it answers a request.
755 A preview is deleted when its pull request closes or merges, and after
756 a set number of idle days. Container apps, later, sleep when idle.
757- **Billed to the customer, never free.** The user (2026-10-04): "we
758 should not be giving any of this available for free". Every deployment
759 is metered per workspace (requests, CPU time, deployed apps, stored
760 data), priced at Cloudflare's cost + 20% like agent usage, and drawn
761 from prepaid credit. `FREE_WHILE_BUILDING` and the free model allowance
762 do not cover deployments: a workspace without credit cannot deploy, and
763 turning deployments on says so first.
764- **Turning them on is a paid plan, the way Cloudflare's is.** "Including
765 things like them even enabling the feature should have that pay like
766 Cloudflare does." Enabling deployments for a workspace starts a monthly
767 fee that includes an allowance of requests, CPU time and deployed apps;
768 usage past it is billed per unit, as Workers for Platforms bills g1t.
769 The fee and allowance are the user's to set.
770- **Recommended, off in one click.** Because enabling costs money, it is
771 never switched on without the workspace agreeing: new repositories
772 recommend it prominently. A repository can turn it off, keep only production, or
773 deploy somewhere else from its own workflows. Apps built for Cloudflare
774 (Workers, static assets, D1, KV, R2) deploy without configuration.
775
776Later, toward GitLab's DevOps breadth: environment protection rules,
777package and container registries, releases, container hosting.
778
779## Projects
780
781> **2026-10-04:** the user: "an extra dimension of Projects so it's not
782> just repositories … where a lot of things can live", "very Vercel
783> like", with dependencies across projects "the Platform Engineering /
784> Port route", and "the repository is *part* of a project: you could be
785> mirroring it from GitHub/GitLab/Bitbucket, or you could let us host it
786> for you", with room for Mercurial or anything else later.
787
788**A project is the thing you are building and running; a repository is
789where some of its code lives.** Everything that is about running software
790(deployments, environments, domains, secrets, dependencies, owners,
791health, upkeep) belongs to the project. What is about the code itself
792(branches, pull requests, review, merge rules) stays with the repository.
793That split is what lets the code live anywhere.
794
795### The model
796
797| | What it is | Like |
798| --- | --- | --- |
799| **Workspace** | The company or team. Members, billing, plans, shared secrets. | Vercel team, GitLab group, GitHub org |
800| **Group** | An optional named set of projects, one level: "Payments", "Mobile". For browsing, ownership and shared settings. | GitLab subgroup, Backstage system, Port domain |
801| **Project** | One deployable thing: a site, an API, a worker, a library. Has exactly one **source**. | Vercel project, Port service, Backstage component |
802| **Source** | Where its code is: a repository and a **root directory** in it. | Vercel's connected repo + root directory |
803| **Dependency** | Project A uses project B: calls its API, consumes its package, reads its queue. | Port relations, Backstage `dependsOn` |
804
805- **One project, one source; one repository, any number of projects.** A
806 project builds from exactly one place, which keeps it as simple as
807 Vercel's. A monorepo is several projects on one repository, each with
808 its own root directory (`apps/web`, `services/api`), and a push builds
809 only the projects whose root it touched. The common case stays 1:1, and
810 every existing repository gets a project of its own name when this
811 ships, so nobody has to set anything up.
812- **Groups are for people; dependencies are for software.** Groups decide
813 where a project shows up and who owns it. Dependencies decide what
814 happens when one changes. Neither replaces the other, and a dependency
815 can cross groups.
816
817### Sources: where the code lives
818
819A source is an adapter behind one interface (`SourcePort`: clone URL,
820branches, commits, pushes as events, pull requests if it has them):
821
822| Source | Code lives | g1t gets pushes by | Pull requests |
823| --- | --- | --- | --- |
824| **Hosted on g1t** (today) | Artifacts | its own events | g1t's, with agents, the queue, review |
825| **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 |
826| **Connected, not copied** | The provider only | webhook | The provider's |
827| **Later:** Mercurial, Perforce, a tarball upload | Behind the same port | per adapter | per adapter |
828
829A mirrored or connected project still gets everything that is the
830project's: previews on its pull requests (a status and a comment on
831GitHub's), production on its default branch, secrets, dependencies,
832upkeep agents. That is the on-ramp: a team keeps GitHub and gets g1t's
833deployments and agents first, and moves the code later or never.
834Bring-your-own-git is also why the project, not the repository, holds the
835URL `g1t.sh/<workspace>/<project>`.
836
837### What lives on a project
838
839| | Today it is on | Moves to the project |
840| --- | --- | --- |
841| Deployments: production, previews, build settings, root directory, framework | The repository | Yes |
842| Environments: production, preview, and custom ones (`staging`) with protection rules (required approvers, branch limits) | Nowhere yet | New, on the project |
843| Domains: `<project>--<workspace>.g1t.page`, and custom domains | The repository's name | Yes |
844| 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). |
845| Dependencies | Nowhere | New |
846| Owners, on-call, links (docs, dashboards, runbooks) | Nowhere | New: the catalog's metadata |
847| Health: scorecards (has an owner, CI passes, dependencies current, no open security alerts, deploys within N days) | Nowhere | New |
848| Upkeep agents: dependency updates, security alerts | The plan | Scoped per project |
849| Logs and analytics of the running app | Nowhere | New: requests, errors and CPU per environment, from Workers analytics |
850| Branches, pull requests, review, merge rules, the queue, webhooks | The repository | Stay |
851
852### Dependencies: why this gets powerful
853
854Declared in the UI, or in the source as `.g1t/project.yml` (which wins
855when present, as `catalog-info.yaml` does in Backstage):
856
857```yaml
858name: web
859root: apps/web
860dependsOn:
861 - project: api # calls its HTTP API
862 as: API_URL # its URL, per environment, as a variable
863 - project: ui-kit # consumes its package
864```
865
866What g1t does with them:
867
8681. **Reference variables.** `API_URL` above resolves to `api`'s production
869 URL in production and to the matching preview in a preview, the way
870 Railway's `${{ api.URL }}` references work. No hard-coded URLs.
8712. **Preview stacks.** A pull request on `api` gets its own preview, and
872 **Preview with dependents** builds `web`'s preview pointed at it, so a
873 reviewer clicks through the whole change across projects. A change that
874 spans repositories (one issue, one fork per repository) gets one stack.
8753. **Release order.** Production deploys go out in dependency order; a
876 change set across projects lands through the queue together or not at
877 all.
8784. **Impact on every pull request.** "Changes `api`; `web` and `mobile`
879 depend on it." Agents get the graph in their context: an agent
880 changing an API opens follow-up issues on the projects that call it,
881 and reviewers see what else could break.
8825. **Upkeep across the graph.** A vulnerable package in `ui-kit` opens
883 issues, assigned to agents, on every project that consumes it.
8846. **Scorecards turn into work.** A project failing a scorecard check
885 ("no owner", "dependencies 90 days old") gets an issue an agent can fix.
886 That is the Port idea with the work done for you.
8877. **The map.** A workspace's projects as a graph, coloured by health and
888 by what is deploying now.
889
890### Pages
891
892- `g1t.sh/<workspace>`: projects first (grouped, with health and
893 production status), then repositories.
894- `g1t.sh/<workspace>/<project>`: overview (production, latest previews,
895 health, owners, dependencies both ways), **Deployments**,
896 **Environments**, **Secrets and variables**, **Logs**, **Settings**
897 (source, root directory, build, domains, groups, owners).
898- A hosted repository keeps its code pages; from a project they are its
899 **Code** tab. A repository page lists the projects built from it.
900
901### Services
902
903- `services/projects` (new): projects, groups, sources, dependencies,
904 owners, scorecards. Events `project.created`, `project.updated`,
905 `dependency.changed`.
906- `services/deployments`: keyed by project instead of repository.
907- Secrets and variables: the scope becomes workspace → project.
908- Sources: the hosted adapter wraps `services/repos`; a mirror adapter
909 per provider in `services/integrations`, which already holds those
910 connections.
911
912### Build order
913
9141. **Projects as the home of deployments and secrets**, 1:1 with every
915 existing repository: the service, the pages, deployments and secrets
916 moved to the project, `<project>--<workspace>.g1t.page`.
9172. **Dependencies:** declared in the UI and `.g1t/project.yml`, reference
918 variables, impact on pull requests and in agents' context, the map.
9193. **Preview stacks** and cross-project change sets.
9204. **Monorepos:** several projects on one repository, each with a root
921 directory, building only what a push touched.
9225. **Mirrored sources:** GitHub first, then GitLab and Bitbucket.
9236. **Groups, owners, scorecards** feeding the upkeep agents.
9247. **Environments** with protection rules; custom domains; logs.
925
926**Step 1 shipped 2026-10-04:** `services/projects`; every repository a
927project of its own name; the site projects-first (workspace page of
928project cards, the project overview at `g1t.sh/<workspace>/<project>`, code
929under `/code`, the sidebar and the New project flow); deployments keyed by
930project and branch at `<project>-<workspace>.g1t.page` and
931`<project>-git-<branch>-<workspace>.g1t.page`; secrets and variables owned
932by the project.
933
934**Step 5, GitHub, built 2026-10-05:** one GitHub App (`g1t-sh`) for both
935sign-in and repository access. Sign-in is its user authorization with PKCE
936(identity, `src/github.rs`): accounts known by GitHub's numeric id, a
937matching verified email never linked without signing in to the account,
938new accounts behind the invite check. Repositories come through its
939installations (integrations, `src/github.rs`), copied with every branch and
940tag by the repos service (`src/mirror.rs`) as **import**, **mirror** (g1t
941follows GitHub on its push webhook) or **move to g1t** (GitHub follows g1t
942on `git.push`). A mirror is a hosted repository that keeps a full copy, so
943its project stays `hosted` and deploys like any other; the tie lives in
944integrations' `github_repos`. Not yet: previews and statuses on GitHub's own
945pull requests, comments and pull requests copied, GitLab and Bitbucket.
946
947### People and search
948
949> **2026-10-04:** "pull up user profiles, using a /u/username prefix kinda
950> like DockerHub … search for users if you search that explicitly, how
951> GitHub has the aside for searching against filters … a significantly
952> stronger implementation."
953
954- **Profiles at `g1t.sh/u/<username>`**, apart from workspaces at
955 `g1t.sh/<workspace>`: who they are, their workspaces, recent work,
956 agents' sessions they steered.
957- **Search with a filter sidebar:** Projects, Code, Issues, Pull requests,
958 Users, Workspaces, each with its count; filters by workspace, language,
959 state, author, agent, label, date; qualifiers in the query
960 (`user:`, `is:open`, `agent:g1t`) as on GitHub. Typing `u/name`
961 searches people directly, as Docker Hub does.
962
9631 and 2 serve the competition directly (multi-agent coordination across
964projects is 25% of the score); 3 is the demo's best moment if time allows.
965
966## Billing model
967
968> **2026-10-04:** "Some things just require you to have a card on file …
969> some things will be something you give us an initial amount of money
970> per month just to activate, tons of things additionally will be usage
971> based, some things will just be usage based only … at minimum a
972> breakeven with Cloudflare costs, or in some cases a value add." Stripe
973> moves to Flagon, Inc. (g1t.sh is its product). Proposed below; the
974> prices are the user's to confirm.
975
976### Four kinds of charge
977
978Every feature is exactly one of these, and the Billing page says which:
979
980| Kind | What the workspace does | Example |
981| --- | --- | --- |
982| **Free** | Nothing | Hosting code, issues, pull requests, review, the merge queue, bringing your own agent over MCP |
983| **Card on file** | Adds a card; pays only for what it uses | Previews, g1t's agents, workflow minutes |
984| **Activation** | Turns a feature on for a monthly fee that includes an allowance; usage past it is metered | Production deployments, Security and quality |
985| **Usage only** | Nothing up front; every unit is metered | Model tokens, build minutes, storage past the free amount |
986
987A card is needed before anything that can cost money starts. Nothing is
988ever switched on without the workspace choosing it.
989
990### Postpaid, with spend limits
991
992- **One Stripe customer and one subscription per workspace**, on Flagon,
993 Inc.'s account. Activations are licensed line items; every usage
994 dimension is a metered price backed by a Stripe Meter. Stripe invoices
995 monthly in arrears and charges the card on file; failed payments go
996 through Stripe's retries and emails, and g1t hears of them by webhook.
997- **Spend limits instead of prepaid credit.** A workspace sets a monthly
998 limit overall and per feature (Vercel's spend management). g1t counts
999 usage as it happens and stops starting new paid work at the limit,
1000 with a warning at 50%, 80% and 100%. Prepaid top-ups go away; promotions
1001 (the free model allowance) become Stripe credit on the customer.
1002- **Usage reaches Stripe from billing alone.** Every service reports
1003 usage to the billing service as it happens (it already records agent
1004 runs and builds); billing batches them into Stripe meter events every
1005 few minutes, idempotently by g1t's own ids, and keeps the ledger g1t's
1006 pages show. Nothing else talks to Stripe.
1007
1008### Scope: workspace, then projects
1009
1010- A feature is turned on for the **workspace** (by an owner, with the
1011 activation if it has one), then allowed for **all projects** or
1012 **selected projects**.
1013- Every **project** can opt out on its own page. A project with nothing
1014 to deploy (no Workers config, no build script, no `index.html`) is
1015 detected, says so on its Deployments page, and never builds or costs
1016 anything.
1017- Agents and workflows are allowed per project the same way, so a
1018 workspace can keep spend to the projects that matter.
1019
1020### Prices: what it costs us, passed through
1021
1022> **2026-10-04, decided:** postpaid with spend limits, as Vercel and
1023> Cloudflare do; no per-seat price, ever ("fuck per-seat pricing").
1024> "If they're barely using them great, but if they're using the shit out
1025> of them that will cost me a ton, so that cost needs to move onto them."
1026
1027**Every Cloudflare cost a workspace causes is metered to it.** Light use
1028fits in a small free allowance; past it, each unit is charged at
1029Cloudflare's price times a margin of at least 1.5, which pays for Stripe
1030(about 3%), shared overhead (the site, the API, D1) and g1t itself.
1031
1032Cloudflare's prices (October 2026), and the cost per unit g1t meters:
1033
1034| What g1t meters | Cloudflare's price | Cost to g1t per unit |
1035| --- | --- | --- |
1036| **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) |
1037| **App request** (deployments) | Workers for Platforms: $0.30 / million past 20M | $0.30 / million |
1038| **App CPU** | $0.02 / million CPU-ms past 60M | $0.02 / million ms |
1039| **App** (a deployed script) | $0.02 / script-month past 1,000 | $0.02 / app-month |
1040| **Storage** (repositories, artifacts, caches) | Artifacts $0.50 / GB-month (billing starts 2026-10-14); KV $0.50 / GB-month | $0.50 / GB-month |
1041| **Git operation** (clone, fetch, push) | Artifacts $0.15 / 1,000 past 10,000 | $0.15 / 1,000 |
1042| **Model tokens** | The provider's price | As charged |
1043| Container egress, emails, the site's own requests | Small and shared | In the margin |
1044
1045> **2026-10-06, decided:** no per-feature quotas on the plan. "A paying
1046> user should be able to push past the Git operations number, they're
1047> just paying usage on it." One plan, $20 a month per workspace with $10
1048> of usage included; every meter is charged from the first unit at cost +
1049> 20% (builds, app requests and CPU, custom domains), drawn from the $10
1050> first, then up to the spend limit, which is the only thing that stops a
1051> paying workspace (with abuse protection). Projects, previews and apps
1052> are not metered (Workers for Platforms' script pool makes them ~free).
1053> The forge's free amounts are the same for everyone: 1 GB private storage
1054> and 50,000 git operations a month; past them the plan pays and a free
1055> workspace is held (pushes stop, git slowed). The table below is the
1056> earlier proposal; billing's price book and g1t.sh/pricing are current.
1057
1058What a workspace pays:
1059
1060| Meter | Free each month | Then | Margin | For comparison |
1061| --- | --- | --- | --- | --- |
1062| 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 |
1063| App requests | 1 million with Deployments | $0.50 / million | 1.7× | Vercel $0.60 / million invocations |
1064| App CPU | 3 million ms with Deployments | $0.04 / million ms | 2× | Vercel active CPU about $0.036 / million ms |
1065| Apps | 10 with Deployments | $0.05 / app-month | 2.5× | |
1066| Storage | 1 GB | $1.00 / GB-month | 2× | GitHub LFS $0.07 / GB, but repositories are free there |
1067| Git operations | 10,000 | $0.30 / 1,000 | 2× | |
1068| g1t's models | | Cost + 20% | 1.2× | The provider's own price |
1069| Your own model provider | | Only its sandbox minutes (the $0.10 run fee was dropped 2026-10-05) | | |
1070| **Deployments** activation | | $5 / month, with the allowances above | covers Workers for Platforms' $25 / month across workspaces | Vercel Pro $20 per seat |
1071| **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 |
1072
1073A workspace that uses g1t lightly (a few agent runs, a small site)
1074pays nothing or its activation; a workspace running agents all day pays
1075for the sandboxes and models those agents use, with g1t's margin on
1076each. Nothing in a workspace's bill is subsidised by another's.
1077
1078### Build order
1079
10801. Stripe customer per workspace and card on file (Checkout in setup
1081 mode), webhooks (invoice paid and failed, subscription changes,
1082 payment method changes), the Billing page rebuilt around the four
1083 kinds.
10842. One subscription per workspace with activations as items; Deployments
1085 moves onto it.
10863. Meters for each usage dimension above, fed from billing's ledger:
1087 every sandbox reports how long it ran when it stops (agents, checks,
1088 the queue, workflow jobs and deploy builds alike); deployments report
1089 requests, CPU and apps; repos report storage and git operations. Spend
1090 limits and their warnings; prepaid credit retired.
10914. Per-workspace allow-lists of projects for each feature, and per-project
1092 opt-out; "nothing to deploy" detection.
10935. Turn off FREE_WHILE_BUILDING when the user says so. **Done 2026-10-05.**
1094
1095Shipped by 2026-10-05: sandbox seconds for every sandbox; the price book
1096and its keeper (runs settled to AI Gateway's price every 15 minutes;
1097Container and Workers costs checked against Cloudflare's billable usage
1098and container analytics daily, with a public change log on
1099g1t.sh/pricing); usage limits by trust with automatic payment near the
1100limit; app traffic counted toward limits as it happens; billing accounts,
1101terms and enterprises; free mode off, syntaqx comped.
1102
1103Still to build, in order: Stripe card-on-file without a payment (setup
1104mode) and webhooks; month-end invoices for postpaid usage (and one
1105invoice per enterprise); the subscription with activations as items;
1106storage and git-operation meters; limit warnings by email at 50/80/100%;
1107self-serve enterprise management for enterprise owners.
1108
1109### Accounts, terms and enterprises
1110
1111Every workspace is paid for by a billing account: its own (`ws_<slug>`)
1112or an enterprise's (`ent_…`), which pays for several workspaces with one
1113limit, one set of terms and, once invoices exist, one bill, as GitHub
1114Enterprise does. Terms are standard, comped (nothing charged, usage still
1115recorded at cost, paid features on) or custom (a discount, its own
1116ceiling, an end date). g1t staff manage them in **sudo.g1t.sh**, a
1117separate Worker behind Cloudflare Access that also verifies the Access
1118token itself and allows only listed staff emails; every change is kept
1119with who made it and why.
1120
1121### Limits: stop non-payers, never payers
1122
1123The limit is on usage not yet paid for, counted at cost to g1t or charge,
1124whichever is more: $3 before any live payment, then twice what has been
1125paid ($25 to $1,000), or what staff set. A workspace with a card on file
1126is charged automatically near its limit, which both pays what it owes and
1127raises the limit, so paying users are never stopped. A declined card
1128stops work until paid. The owner's own spend limit always means stop.
1129Test-mode payments never lower exposure or raise trust.
1130
1131### Tax, card fees and free workspaces (built 2026-10-08)
1132
1133> **2026-10-08, decided:** Stripe Tax everywhere ("so I don't fuck up on
1134> taxes"); Stripe's card fee passed to the customer with the 20% markup
1135> kept; one free workspace per person; no invites on free workspaces.
1136
1137- **Stripe Tax on every payment.** `automatic_tax` on every Checkout page
1138 (plan, Security and quality, prepaying, AI credit), every subscription
1139 and every invoice g1t makes (month close, threshold, enterprise), and a
1140 tax calculation and transaction for auto-reload's off-session charge.
1141 Tax code `txcd_10103001` (SaaS, business use), every price
1142 `tax_behavior=exclusive`. Checkout always collects the billing address
1143 and tax ID and saves them on the customer. Prices on g1t are shown
1144 excluding tax. Tax is never revenue: balances and plan payments are
1145 credited without it, it is kept in `tax_and_fees`, shown as its own
1146 statement line, and as **Tax collected** on sudo's Costs. Without an
1147 address g1t does not charge: the owners are asked for one.
1148- **The card fee** (2.9% + $0.30, grossed up) is its own line on every
1149 card payment, the plan's and Security's as a monthly item; never on a
1150 bank transfer or an enterprise's invoice. On by default
1151 (`cost_settings.card_fee`). Not revenue either. Meters stay at cost +
1152 20%; models at the provider's price plus the agent rate.
1153- **One free workspace per person.** Identity asks billing
1154 (`free_workspaces`) before creating one; a second is refused with the
1155 way forward. Those who own several from before keep them.
1156- **A free workspace adds no one**: no members, invites or outside
1157 collaborators until it starts the plan; its members stay; @g1t never
1158 counts. Enforced in identity for every path (site, API, MCP).
1159- Details: docs/BILLING_OPERATIONS.md, *Tax and the card fee*.
1160
1161### Promo codes (planned)
1162
1163Staff credits (promotional, goodwill, refund; `services/billing/src/grants.rs`,
1164docs/BILLING_OPERATIONS.md) are given one workspace at a time. Promo codes
1165give promotional credit in bulk, on redemption, through the same grants:
1166
1167- **Codes.** sudo → Credits & refunds → **New code**: the code (or one
1168 made up), the credit ($ amount), max redemptions, when the code stops
1169 working, how long each redeemed credit lasts (an expiry, as any grant),
1170 and a note. Table `promo_codes` (code, amount, max, redeemed, ends_at,
1171 credit_days, note, created_by, disabled_at) and `promo_redemptions`
1172 (code, workspace, grant id, by, at), unique on (code, workspace).
1173- **Redeeming.** An owner types it on the workspace's Billing page
1174 (`redeem_code`, owners only). One D1 batch checks the code is open, under
1175 its max and not redeemed by the workspace, counts the redemption and
1176 makes the grant (`grant_credit`, kind promotional, the code as its note),
1177 so two redemptions at once never pass the max. Wrong or used-up codes say
1178 so without telling which codes exist; redemptions are rate-limited per
1179 owner.
1180- **Seeing them.** Each code's redemptions, credit given and spent come
1181 from the grants it made, so margin needs nothing new: spent promo credit
1182 is already given away, by kind.
1183- **Not yet built** because it adds an owner-facing form, abuse limits and
1184 a second sudo form; giving credit by workspace covers launch.
1185
1186## Agents and models
1187
1188### Defining an agent
1189
1190An agent is a file (`.g1t/agents/<name>.md`, or in the workspace library):
1191instructions, the harness and model to run, the tools and MCP servers it may
1192use, its sandbox image, permissions and budget. Agents take roles: planner,
1193implementer, reviewer, conflict resolver, documenter, memory consolidator.
1194Each role has a default that a repo can replace.
1195
1196### Where it runs, and on whose model
1197
1198| Option | How it works | Fits |
1199| --- | --- | --- |
1200| Hosted, g1t's model | g1t runs the sandbox and bills usage | Getting started; no keys to manage |
1201| Hosted, your API key | Same sandbox, your Anthropic, OpenAI or Google key | Teams with existing contracts |
1202| Hosted, your endpoint | Any OpenAI-compatible URL: Bedrock, Vertex, Azure, a self-hosted model | Private or fine-tuned models |
1203| Your runner | A g1t runner daemon on your own machines picks up pull requests | Code or models that may not leave your network |
1204| Your own session | Local Claude Code, Cursor or any MCP client joins through `mcp.g1t.sh` | Individuals; subscription plans |
1205
1206Decisions behind this:
1207
1208- **g1t does not build its own agent loop.** It runs existing harnesses
1209 (Claude Code first, through its headless mode) behind a small runner
1210 contract: a container image, an entry command, and session events reported
1211 through the CLI. Other harnesses plug in by meeting the contract.
1212- **All hosted model traffic goes through Cloudflare AI Gateway.** That gives
1213 one place for spend tracking, budgets, rate limits, fallback and logs,
1214 whichever provider or endpoint is behind it.
1215- **Nobody has to pick a model.** A person assigns work to `g1t`, as
1216 they would assign an issue to a colleague, and **Auto** routes each job
1217 to the cheapest model that can do it (see
1218 [Routing for cost](#routing-for-cost) below). A workspace can pin a tier
1219 per kind of work instead. Each request is tagged at the gateway with the
1220 kind of work, the tier, the repository and the pull request, and each
1221 run says which model ran and why. The gateway's own dynamic routes
1222 cannot make the choice yet: they work only on its OpenAI-compatible
1223 endpoint, and the harness speaks Anthropic's.
1224- **Subscriptions stay local.** A Claude subscription cannot be used by a
1225 hosted sandbox; it needs an API key. People on subscriptions use their own
1226 Claude Code session, which is a full participant.
1227- **The workspace pays.** A workspace buys AI credit by card and each
1228 agent run deducts the model at the provider's price plus the agent rate
1229 per million (weighted) tokens; on its own model key, only the agent rate,
1230 counted from the model proxy and the sandbox's own report. The billing service asks
1231 nothing of the others: the runner asks it before starting a sandbox and
1232 is refused when there is no credit, and the sandbox reports what its run
1233 cost with a token only it holds. Where no card processor is configured
1234 nothing is charged and agents stay limited to listed accounts.
1235- **Keys are secrets.** Stored in Cloudflare Secrets Store, injected into the
1236 sandbox for one pull request, never shown again.
1237
1238### Seeing a pull request through
1239
1240Assigning an issue is the only thing a person does until there is something
1241to merge. A pull request made by g1t goes through checks, a review
1242by another agent, revision when either finds something, and catching up
1243when `main` moves, without anyone pressing a button. It ends as ready to
1244merge, or as "needs you" with the reason: the checks still fail after two
1245revisions, a review could not be written, or a conflict could not be
1246resolved.
1247
1248The work service decides the next step from the pull request's state and
1249claims it in one statement, so a step is taken once. The runner asks on
1250every event that could change the answer (ready, pushed, checks finished,
1251review finished, `main` moved), and on a five-minute sweep for anything
1252missed, and carries the step out in a sandbox.
1253
1254A pull request does not have to be up to date with `main` to merge,
1255unless the repository's settings require it, as on GitHub. Merging one that
1256is behind brings it up to date first (a clean merge needs no model; an
1257agent resolves a conflict) and lands it when that push arrives. With the
1258requirement on, catching up is a step of its own and the checks run again
1259on the result.
1260
1261Each repository sets its own rules, on one settings page: whether its
1262default branch takes pushes at all, how many approvals a merge needs and
1263whether an agent's counts, whether failed checks can be overridden, whether
1264a second agent reviews, and how often an agent is sent back before a person
1265is asked. A pull request g1t opens follows the same rules as anyone's.
1266Pushes to a protected branch are refused in the git front end, with the
1267reason shown by git beside the branch.
1268
1269Merging is a person's decision unless the repository says otherwise. With
1270"merge automatically when ready" turned on in its settings, a ready pull
1271request lands by itself, attributed to `g1t`. That is the whole path from
1272an assigned issue to a commit on `main` with nobody in between. Required
1273human approval per path, and risk tiers, are still to come.
1274
1275### Routing for cost
1276
1277*Built (runner `route` in `services/runner/src/model-env.ts`).* The goal
1278is cost per merged change, not cost per request: a cheap attempt that
1279fails and is retried on the same model costs more than one that finishes.
1280
1281- **Tiers and catalogue.** `small` (Claude Haiku 5.5 since 2026-10-08,
1282 $0.10/$0.50 per million input/output up to 100k-token prompts, five
1283 times that above; it was Haiku 4.5 at $1/$5), `large` (Claude Sonnet 5.5, $2/$10) and `frontier`
1284 (Claude Opus 5.5, $4/$20). Models, names and list prices are data,
1285 never code: since 2026-10-08 billing's model catalogue
1286 (`gateway_models`, one row per model g1t can use) and staff's defaults
1287 in sudo, **Agents & models** (`model_defaults`: each tier's model, the
1288 harness's background model, the AI Gateway's first Claude, each job's
1289 starting tier and effort), read by the runner once a minute over
1290 `AGENT_ROUTING`, which is only the fallback when billing cannot be read.
1291 Catalogue prices are for estimates only; runs are charged what AI
1292 Gateway priced them at.
1293- **Keeping up with new models (built 2026-10-08).** The models service
1294 lists Anthropic's models (through the AI Gateway) and Workers AI's daily
1295 and on demand; a new id lands in the catalogue as `new`, priced from a
1296 maintained table of Anthropic's list prices or Workers AI's listing, or
1297 unpriced, and staff are emailed. Nothing routes to it, offers it or
1298 charges for it until staff approve it with its prices. A model a provider
1299 stops listing is `deprecated`; routing never sends work to a deprecated
1300 or retired model, falling back to the next model of the tier and saying
1301 so on the run. Customers keep Auto: the catalogue is staff's. See
1302 [BILLING_OPERATIONS.md](BILLING_OPERATIONS.md#the-model-catalogue).
1303- **Starting tier by job.** Catch-up, answering a question, and reviews of
1304 at most 10 files and 200 lines touching no sensitive path: small.
1305 Plans: small at high effort (Haiku 5.5 takes an effort level).
1306 Changes, revisions and other reviews: large. Reviews over 60 files
1307 or 3,000 lines: frontier. Labels: `architecture` frontier, `security` off
1308 small, `docs`/`documentation`/`typo` let changes and answers start small.
1309- **Escalation.** A failed (or guardrail-stopped) attempt at the same work
1310 goes one tier up; two in a row, frontier; a revision counts its rounds;
1311 a change left at low confidence sends the next attempt up.
1312- **Learning, per repository.** From the last 20 runs of the same kind:
1313 one tier down when the cheaper tier finished at least 90% of at least 5
1314 (never for sensitive or labelled work, never on a retry); one tier up
1315 when this tier failed at least half of at least 5. No new tables: it
1316 reads work's `agent_runs` (model, status, confidence).
1317- **Explained.** Every run's first step and session note is one line:
1318 *Used a fast model (Claude Haiku 5.5): small change, 3 files and 80
1319 lines.* Effort per kind of job (`effort` in `AGENT_ROUTING`: plan high,
1320 answer medium, update low) is sent as `CLAUDE_CODE_EFFORT_LEVEL` on
1321 g1t's tiers (never on a model the catalogue says takes none) and named
1322 in that line, with the catalogue's name for the model.
1323- **Chosen instead.** `model_routes` rows to g1t's models name `small`,
1324 `large` or `frontier`, or nothing for Auto (Integrations → Models).
1325 A workspace's own Anthropic key with no model named is routed by Auto
1326 too.
1327- **Measured.** `scripts/ops/routing-savings.mjs` replays tasks through
1328 the router offline, priced from the catalogue, against routing before
1329 Auto and against the frontier model for everything, net of failed
1330 attempts, with cost per merged change; `--live` reads billing's runs and
1331 counted tokens. On the bundled sample (13 tasks, assumed failures): Auto
1332 costs 7% less than the frontier model for everything and about 7% more
1333 per run than routing before it, but half as much per merged change,
1334 because it finishes the hard tasks the old routing gave up on. At
1335 current prices Opus 5.5 and Sonnet 5.5 cost the same per cache read, and
1336 cache reads are most of an agent run's tokens, so moving off the
1337 frontier model saves less than its list price suggests; the fast tier
1338 and fewer failed attempts are where the money is. Run `--live` monthly
1339 and after any routing change.
1340- **A cheaper route for the simplest jobs (designed, off).** A fourth tier
1341 on Workers AI through AI Gateway (an open model, billed on Cloudflare's
1342 invoice) for classification-sized jobs: commit messages, triage,
1343 summaries. Behind the same router as a tier with its own catalogue entry
1344 and `tasks` rules, off by default. It needs the proxy to translate the
1345 harness's Anthropic requests to the gateway's OpenAI-compatible
1346 endpoint (it already does for workspaces' own OpenAI-shaped providers)
1347 and a quality bar from the savings harness before any job moves to it.
1348
1349### Choosing the right agent automatically
1350
1351Because several agents can work on the same issue, every issue with more
1352than one pull request is an evaluation on real work. g1t records, per repo and per kind of issue, each
1353agent's win rate, cost and time. That produces a leaderboard, and a routing
1354policy: send each new issue to the agent that wins that kind most often,
1355start with the cheapest that is good enough, and escalate to a stronger one
1356when checks fail.
1357
1358## Talking: the inbox and channels
1359
1360Not a discussions forum. People and agents need one place to talk in real
1361time, and an app that feels like one on desktop and phone.
1362
1363**The inbox comes first.** Everything that needs a person or that they
1364follow, from people and agents: review requests, agent questions and
1365handoffs, failures, mentions, deploys. Read and unread, saved, done,
1366snoozed; ranked so what an agent is blocked on comes first; email digests
1367and push. It is the delivery layer chat needs too (who is told what, read
1368state, push), so building it first makes channels cheap.
1369
1370*Built:* the events service keeps it (`services/events/src/inbox.rs` and
1371`subscriptions.rs`, migrations `0005_inbox` and `0006_inbox_threads` on the
1372`g1t-events` database), writing items as events arrive from the bus; work's
1373`inbox_subject` says what each event names. Each person has one **thread**
1374per issue, pull request, workflow on a branch or deployment: new activity
1375brings it back unread with a count and its last 10 activities, and while it
1376is unread its most urgent severity is kept. Each item has a **reason**
1377(`agent`, `review_requested`, `assign`, `mention`, `ci_activity`,
1378`security_alert`, `state_change`, `author`, `comment`, `manual`,
1379`subscribed`). Who is told: `agent.asked` and `pull.stalled` (needs you,
1380closed again by `pull.resumed` and the like), `pull.review_requested`
1381(needs you, closed by `pull.review_request_removed`),
1382`issue.assigned`/`pull.assigned`, failed checks and workflows,
1383`deployment.failed` and a recovering `deployment.succeeded`, g1t's reviews
1384and finished changes, closes, reopens and merges to everyone subscribed,
1385and comments to the people mentioned and everyone subscribed. Never the
1386actor, never g1t. **Subscriptions**: authors, assignees and reviewers are
1387subscribed without a row; commenting or being mentioned subscribes; anyone
1388can subscribe, unsubscribe (still told of what is asked of them) or ignore.
1389**Watching** a repository: participating (the default), all, ignore, or
1390custom (issues, pulls, deployments, security); whoever creates a repository
1391watches it at their default, all activity unless they change it.
1392**Settings**: which reasons are also emailed (agent, review_requested and
1393mention by default) and the default watch for new repositories; email goes
1394through identity's `notify_by_email`, to a confirmed address only while the
1395person can still read the repository. **REST and MCP**: 14 operations under
1396`/notifications`, `/repos/:owner/:name/subscription` and
1397`/user/subscriptions` (scopes `notifications:read` and
1398`notifications:write`, in the Agent preset), and the `notifications` MCP
1399tool; never usable by g1t's own tokens. On the site: a bell in the top bar
1400opening a sheet with tabs (All, Needs you, Errors, Success, Info), Done,
1401Save, Snooze and Mark all read; `/inbox` with Saved, Done and a reason
1402filter; reasons and update counts on each card; a Notifications box on
1403issue and pull request pages; a Watch menu in the repository header;
1404Settings → Notifications; a Needs you card on mission control. Agent sits
1405beside the bell, disabled. Still to come: security alerts (the security
1406service publishes no event yet), email digests and push, Agent, and
1407channels.
1408
1409**Channels** (working name): workspace channels, direct messages and
1410threads, live.
1411
1412- Each channel is a Durable Object holding its WebSocket connections with
1413 hibernation, so idle channels cost nothing; history in D1, files in R2.
1414- Agents are members. `@g1t` in a channel starts work, answers, or
1415 posts a summary; agents post their questions and handoffs where people
1416 already are. A thread becomes an issue or an outcome in one action, and
1417 the agent's progress streams into that thread.
1418- Tied to the work: issues, pull requests, runs and deploys each have a
1419 thread; links unfurl into live cards (checks, agent step, preview).
1420 What a channel settles can become workspace memory, with its source.
1421- Apps: an installable PWA first (desktop and mobile, offline shell, Web
1422 Push), then native shells on the same API: Tauri for desktop (tray,
1423 deep links), React Native for iOS and Android (background
1424 notifications).
1425
1426GitHub-style Discussions are not planned: channels and threads on the
1427work replace them.
1428
1429## What GitHub ships today, and where g1t differs
1430
1431GitHub's Agent HQ and Copilot app give each agent session its own git
1432worktree and branch, list sessions in a mission-control view grouped by
1433project, and let a task be assigned to several agents so their output can be
1434compared. Underneath, the unit of work is still a branch and a pull request.
1435
1436| | GitHub | g1t |
1437| --- | --- | --- |
1438| 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 |
1439| Agent context | Lives in the app's session view | Stored with the repository and linked from each commit (why-blame) |
1440| 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 |
1441| Collisions between agents | Found as merge conflicts at the end | Flagged during the work (overlap radar) |
1442| Landing changes | One pull request at a time | A merge queue that lands the chosen one and closes the rest as superseded |
1443| Which agents | Those offered through a Copilot subscription | Any MCP client, plus hosted agents |
1444
1445## How agents connect
1446
14471. **Bring your own agent.** A remote MCP server at `mcp.g1t.sh` lets Claude
1448 Code (or any MCP client) list issues, claim one, get a clone URL and
1449 token, report progress and submit. Adding it is one command; sign-in is a
1450 browser OAuth flow with no token to paste. The `g1t` CLI installs Claude
1451 Code hooks that upload the session transcript as the agent works.
14522. **g1t's agent.** Assign an issue to g1t, or many issues at
1453 once, each to an agent of its own. g1t starts a sandbox for each
1454 (Cloudflare Containers), running a coding agent headless against its
1455 own pull request and fork.
14563. **API and CLI.** Everything above is available at `api.g1t.sh` and
1457 through `g1t`.
1458
1459## Public surfaces
1460
1461| Host | What it serves |
1462| --- | --- |
1463| `g1t.sh` | The site, git over HTTPS, git over SSH |
1464| `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 |
1465| `mcp.g1t.sh` | Remote MCP server over streamable HTTP |
1466
1467g1t is its own OAuth 2.1 authorization server: authorization code with PKCE,
1468dynamic client registration that stores nothing (a client id encodes its
1469own registration, so the open endpoint cannot be used to fill a database),
1470discovery metadata and rotating refresh tokens. Still to come: scopes
1471per resource (`repo:read`, `repo:write`, `issue:write`, `pull:write`).
1472MCP clients, the CLI (device flow) and third-party apps all use it. Access
1473tokens and SSH keys remain for git itself.
1474
1475### Workspace aliases (internal, built 2026-10-07)
1476
1477`g1t` is the product; `flagon-io` is Flagon, Inc., the organization that
1478builds it. So nobody mistakes one for the other, `g1t.sh/g1t` leads to
1479`g1t.sh/flagon-io`. That is a workspace alias: a name g1t's staff point at
1480a workspace, kept in identity's `workspace_aliases` (migration 0029, which
1481seeds `g1t`) by the workspace's id, so it follows renames. It is not a
1482customer feature and is not documented for users; staff add and remove
1483aliases on sudo's Aliases page, with a reason, in sudo's audit log. We may
1484give other companies one for a trading name the same way.
1485
1486An alias is resolved wherever an old slug is (identity's `resolve_slug`),
1487so it costs only the not-found path: site pages 301 to the same page under
1488the workspace, the API and MCP run the call again under its slug, package
1489registries 301, and git over HTTPS is answered in place
1490(`resolve_alias`), because pushes do not follow redirects. An alias is
1491never a route, a username or a workspace's slug, and nobody can register
1492it while it exists. `@g1t` stays g1t's agent: mentions link to how the
1493agent works, never to `/g1t`.
1494
1495## Architecture
1496
1497| Component | Language | Runs on | Responsibility |
1498| --- | --- | --- | --- |
1499| `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. |
1500| `services/identity` | Rust | Worker + D1 | Accounts, workspaces and memberships, sessions, SSH keys, access tokens, device sign-in, OAuth codes and grants |
1501| `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. |
1502| `services/work` | Rust | Worker + D1 | Issues, pull requests, comments, sessions; later a Durable Object per repo for the landing queue and live state |
1503| `services/billing` | Rust | Worker + D1 + Stripe | Each workspace's agent credit: payments, the ledger of every run, and the gate on starting one |
1504| `services/events` | Rust | Worker + Queues + D1 | The event bus: durable log, and one queue per subscribing service |
1505| `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 |
1506| `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 |
1507| `apps/web` | TypeScript | Worker | Server-rendered site. Holds no data; calls services over RPC. |
1508| `apps/docs` | TypeScript | Worker (static) | Documentation and the API explorer |
1509| `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 |
1510| `crates/sshd` | Rust | Container | Git over SSH, bridged to Artifacts |
1511| `crates/merged` | Rust | Container | Trial merges, conflict matrix, landing merges (needs real git; the Artifacts binding is read-only) |
1512| `crates/core` | Rust | native and WASM | pkt-line, packfile and diff code shared by the above and by the Worker |
1513| `crates/g1t` | Rust | user's machine | CLI: auth, SSH proxy, Claude Code hooks, issues and pull requests |
1514
1515Storage: Artifacts for repositories (one fork per pull request), D1 for accounts
1516and metadata, R2 for session transcripts and logs, Durable Object SQLite for
1517per-repo coordination state.
1518
1519How the services fit together:
1520
1521- **Each service is its own Worker with its own database.** It deploys,
1522 scales and fails on its own. Callers reach it through a typed RPC binding
1523 to the interface in `packages/contracts`.
1524- **Expected failures are values.** Every call returns a `Result`, so "not
1525 found" or "forbidden" crosses a service boundary as data.
1526- **Side effects travel as events.** A service publishes what happened
1527 (`git.push`, `issue.opened`, `pull.merged`, …) to the bus and does not
1528 call other services to react. Each subscriber consumes from its own queue.
1529 Timelines, webhooks and automations read the same stream, which is what
1530 lets something like GitHub Actions be built on top.
1531- **Every read takes the viewer.** Authorization is decided inside the
1532 service that owns the data, not by its callers.
1533
1534The Workers runtime scales request handling on its own, so the edge layer
1535stays in TypeScript. Rust is used where there is real computation or a real
1536protocol to implement.
1537
1538## Languages
1539
1540The site is TypeScript. Everything behind it is Rust, compiled to
1541WebAssembly for Workers and natively for containers and the CLI. Identity, repos, work, events and the API are all Rust. The one exception
1542is the Worker that starts sandboxes, because Cloudflare's Containers
1543library is TypeScript. Rust services speak a
1544small JSON protocol over service bindings (`POST /rpc/<method>`), with the
1545types in `crates/contracts`.
1546
1547## Identifiers
1548
1549Every id is a [TypeID](https://github.com/jetify-com/typeid): a prefix naming
1550the kind of thing, then a UUIDv7 in lowercase base32, such as
1551`pr_01jb2k7x9hfq0b3zj0f5s2m8ra`.
1552
1553- The prefix makes an id self-describing and stops ids of different kinds
1554 being mixed up.
1555- Ids sort by creation time as plain strings. In SQLite (D1 and Durable
1556 Objects) that keeps inserts at the end of the primary-key index instead of
1557 scattering them, and gives time-ordered paging for free.
1558- The suffix decodes to a standard UUIDv7 for any system that wants one.
1559- Ids are made by the service that creates the record, not by the database,
1560 so they work across services and can be assigned before a write.
1561
1562## Events at scale, and audit
1563
1564The current event log is a single D1 database. That is fine for a
1565prototype and wrong for the target: D1 is one writer and 10 GB. The design
1566for volume splits storage by how the data is read.
1567
1568| Tier | Store | Holds | Read by |
1569| --- | --- | --- | --- |
1570| Hot | A Durable Object per repository, with SQLite | Recent events for that repo | Timelines, live pages over WebSocket |
1571| Complete | Cloudflare Pipelines into R2 as Apache Iceberg | Every event, forever, partitioned by day and workspace | Analytics, standups, "ask", export |
1572| Audit | The same R2 store, under object lock | Who did what, from where, with which credential | Compliance, investigation |
1573
1574- **No single hot database.** Each repository's recent events live with that
1575 repository, so load spreads across as many objects as there are repos.
1576- **The complete record is files, not rows.** Iceberg on R2 has no practical
1577 size limit and is queried with SQL.
1578- **Audit is a property of every event.** The envelope carries the actor
1579 (person, agent, token or system), the credential used, the request id and
1580 the source address. Audit entries for a workspace are hash-chained, so a
1581 removed or altered entry is detectable, and are written under a retention
1582 lock.
1583- **Delivery is at least once.** Consumers are idempotent on the event id.
1584
1585## Accounts and forge basics
1586
1587- Registration with email verification, sign-in, forgot password (Cloudflare
1588 Email Sending), Turnstile on public forms.
1589- GitHub sign-in, SSH keys, access tokens, active sessions.
1590- Profiles, public and private repositories, repository search (D1 full-text).
1591- Rendered README, syntax highlighting, commit history, diffs.
1592- Transferring a repository between workspaces (by id: its git store key
1593 never moves; every service follows `repo.transferred`; old paths redirect
1594 until reused) and deleting an empty, settled workspace (its slug is
1595 tombstoned, never reissued except to the person whose username it is).
1596- Access: five repository roles, a workspace base permission, outside
1597 collaborators and invitations. Teams are built on it (2026-10-07): visible
1598 or secret, nested up to 8 levels (child teams inherit their parents'
1599 roles), run by maintainers and owners. A team's role on a repository is a
1600 `repo_grants` row whose principal is the team, which identity resolves
1601 into the same `RepoGrant`s on each person, so `access::can` needs nothing
1602 new: the highest role wins. `@workspace/team` mentions tell the team's
1603 people; a team asked to review either asks everyone or picks people by
1604 round robin or load balance.
1605- CODEOWNERS, read in both conventions (single-section, and sections with
1606 approval counts, optional sections and default owners) from the first of
1607 `.g1t/`, `.github/`, the root, `docs/` and `.gitlab/`. Owners are asked to
1608 review, the `g1t / codeowners` status lints a changed file, and branch
1609 protection's "Require review from code owners" holds merges, for people,
1610 agents and the queue alike, until each owning rule is approved.

1631## Running g1t yourself

1633g1t.sh runs on Cloudflare, and that does not change. The core is MIT and
1634must also run on anyone's own machine with `docker compose up`. A free
1635core people can self-host is what makes paid hosting worth trusting.
1636Self-hosting never makes hosted worse: hosted code paths keep their
1637behaviour, and a self-hosted adapter sits beside the hosted one. The
1638inventory of every Cloudflare dependency, the design and the risks are in
1639[SELF_HOSTING.md](SELF_HOSTING.md).
1640
1641The approach: the Workers stay Workers, and self-hosted they run in
1642workerd, the open-source Workers runtime. D1, KV and Queues are SQLite on a
1643volume, with the same migrations. Cloudflare-only bindings are replaced
1644by stand-ins:
1645
1646- Artifacts becomes bare repositories served by `git http-backend`;
1647- Email Sending becomes SMTP, through Mailpit;
1648- services that are off answer "off" instead of failing.
1649
1650| Phase | Scope | Estimate |
1651| --- | --- | --- |
1652| 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 |
1653| 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 |
1654| 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 |
1655| 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 |

1657## The submission
1658
1659- **g1t is built on g1t.** This repository is hosted on g1t.sh, its features
1660 are opened as issues and built by racing agents, and it deploys from
1661 Artifacts through Workers Builds. The history is the proof.
1662- **The demo follows one story.** A brief becomes a project; twelve issues
1663 fan out to dozens of agents; agents notice each other, hand off, and
1664 resolve a conflict; reviewers triage; the queue lands everything on
1665 `main`; why-blame explains a line; the portfolio shows where it all
1666 stands. Then the same thing at a thousand agents.
1667- **Judges can try it in a minute.** Open registration on g1t.sh, one-click
1668 import of a GitHub repo, one command to connect Claude Code, a seeded demo
1669 workspace, and a single deploy command for running their own copy.
1670- **The formats are open.** The commit trailers, session format and runner
1671 contract are published so other tools can interoperate.
1672
1673## Build order
1674
1675What is left is ordered by how much it shows the point above, not by forge
1676parity. Forge basics are done well enough; each item below should make the
1677demo's story stronger.
1678
1679Done from this list: the outcome page (a plan's issues as a live graph with
1680cost and a feed of what happened), coordination you can see (agents' issues
1681and comments stand out in the feed; agents hold g1t's tools through a token
1682scoped to one repository), steering a running agent (messages delivered
1683between steps, and at the end), and recording sessions from anyone's own
1684Claude Code (`curl -fsSL https://g1t.sh/install/claude.sh | sh`). Integrations are
1685in: a workspace's own model provider (Anthropic or any Anthropic-compatible
1686endpoint, reached through a model proxy so no sandbox holds a key; its
1687runs pay only their sandbox time), alerts from Sentry, Datadog and signed webhooks
1688that open one issue per problem and can start an agent, and Jira and Linear
1689tickets that agents read, people import, and that hear back. Racing a
1690set number of agents on one issue is dropped: choosing how many agents to
1691use is not something people should have to do.
1692
16931. ~~**Handoffs and questions between agents** as states on the outcome
1694 page.~~ Done: questions and handoffs show as waiting, read, answered,
1695 taken on or declined; since 2026-10-03 an agent asked while it is not at
1696 work is woken to answer, where before the question waited forever.
16972. **Upkeep agents** (above): dependency updates, secret scanning,
1698 vulnerability alerts, code scanning, the security page. No new
1699 infrastructure.
17003. **Deployments on `g1t.page`** (above): previews per pull request,
1701 production on merge, the reviewer agent checking the preview.
17024. **The large run, building 2 and 3.** About 20–30 issues on g1t itself,
1703 built by agents and landed through the queue, for the video: g1t built
1704 on g1t.
17055. **Polish for judges trying it in a minute:** a seeded demo workspace, the
1706 empty states, and the first-run path from sign-up to an outcome landing.
1707
1708Earlier items still open, after those:
1709
17101. Deleting a branch once its pull request merges; risk tiers. (Approval
1711 rules per path are in, as CODEOWNERS.)
17122. Scopes on OAuth grants and access tokens.
17133. Event storage per the design above: per-repo hot log, Iceberg on R2,
1714 hash-chained audit.
17154. CLI with Claude Code hooks to record sessions automatically.
17165. Reviewing and catching up automatically, by policy; required reviews;
1717 risk tiers.
17186. Compare view, proof bundles; handoff between agents.
17197. Projects, mission control, steering; why-blame, digest, timeline.
17208. Context hub, portfolio; automations and integrations (Sentry first).
17219. SSH; bot protection; own keys, endpoints and runners.
172210. Large run (100+ agents across many issues), hardening, demo.
1723
1724Later: code search, mirroring to GitHub, passkeys, SSH
1725on port 22 without the CLI proxy (needs the Workers inbound TCP private
1726beta).
