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**GitHub is where people keep code. g1t is where a team of agents ships it.**
15
16Hosting git is table stakes, and g1t does it the way GitHub does: 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. GitHub, Origin and Entire all stop 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### Against the others
38
39| | GitHub | Cursor Origin | Entire | g1t |
40| --- | --- | --- | --- | --- |
41| Core idea | Code hosting with Copilot bolted on | A forge for Cursor's cloud agents | Store every agent session with the code | Agents converge an outcome onto `main` |
42| Unit of work | Pull request | Pull request, stacked | Commit plus session | Outcome → plan → issues → pull requests |
43| Agent context | In the Copilot app | In Cursor | In the repo, per commit | Per commit, plus why-blame on any line and what agents told each other |
44| Many agents at once | Compare outputs by hand | Agents can review agents | Not the focus | Plan with dependencies, overlap awareness, coordination tools, queue |
45| Landing | Merge queue (paid) | Stacks | Not the focus | Speculative queue testing combinations; failures return to their agent |
46| Which agents | Copilot, some others | Cursor's | Any (CLI) | Hosted agents plus any MCP client |
47
48Entire's insight, that the session belongs with the code, is one g1t shares
49and already ships (sessions, why-blame). Origin's, that agents should live in
50the forge, too. Neither coordinates a team of agents towards an outcome; that
51is the gap g1t is built for.
52
53## Product model
54
55g1t keeps the two things every engineer already knows, issues and pull
56requests, and changes the assumption underneath them. A forge built for
57people expects a few changes in flight, each watched by its author. g1t
58expects dozens of agents working at once across a project, each on its own
59issue, all of which have to land on `main`. A person assigns an issue to
60the g1t agent and chooses nothing else: not how many agents, and not which
61model. An issue can still collect more than one pull request (a second
62attempt, or someone's own agent alongside g1t's), and when it does the
63issue records which one was taken.
64
65| Concept | What it is |
66| --- | --- |
67| **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. |
68| **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. |
69| **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. |
70| **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. |
71| **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. |
72
73Issues and pull requests share one sequence of numbers per repository, so
74`#12` names exactly one of them.
75
76Features that fall out of the model:
77
78- **Why-blame.** Click a line and see the prompt and reasoning that produced
79 it, not only the commit.
80- **Overlap radar.** Pull requests that touch the same files are flagged
81 while the agents are still working, and the agents are told.
82- **Live lanes.** Watch every pull request progress in real time.
83
84## Why issues and pull requests, not something new
85
86An earlier version of this plan merged the two into one new object, an
87"issue" holding "pull requests". That was wrong, for three reasons.
88
89- **Issues come from everywhere.** People file them, agents file them, and
90 Sentry files them. Most are never worked on by whoever opened them. They
91 need their own life: labels, triage, discussion, closing as not planned.
92- **"Which change did we take?" needs two objects.** When five agents each
93 propose a change, the answer has to be recorded somewhere other than the
94 five proposals. On g1t it is on the issue: `resolved by #14`.
95- **Nobody should have to learn a word to use the product.** An engineer who
96 has used any forge can use g1t on the first day, and finds the agent
97 features where they would look for them.
98
99What g1t adds to the familiar pair:
100
101- **Several pull requests per issue is supported**, not an accident. It
102 is the exception, for a second attempt or a competing one, but when it
103 happens the issue's page lists them with their state, and merging one
104 closes the issue with that pull request recorded and the others marked
105 superseded.
106- **A pull request can be part of the work.** Merging with "keep the issue
107 open" leaves the issue and its other pull requests alone.
108- **Every pull request has a fork and a session.** See
109 [forks and branches](https://docs.g1t.sh/concepts/forks/).
110- **Labels need no setup.** A repository starts with `bug`, `feature`,
111 `docs`, `chore` and `question`; any other name becomes a label the first
112 time it is used, so an integration can tag what it files.
113- **The developer path is unchanged.** Push a branch, open a pull request
114 from it, get review, merge. Agents get a fork per pull request instead.
115- **Both paths meet at `main`.** The same landing rules apply to a person's
116 pull request and an agent's.
117
118## Converging on main
119
120Twelve issues started together will finish at different times and touch
121overlapping code. Getting them all into `main` without a person refereeing
122is the hard part, and it is handled in four places.
123
1241. **Before work starts: plan the overlap away.** A project is a graph of
125 issues. A planner agent can split a large goal into issues, predict
126 which files each will touch, and add a dependency where two would collide,
127 so one starts from the other's result instead of from `main`.
1282. **While agents work: overlap radar.** Each pull request's changed files and
129 symbols are tracked as it pushes. When two pull requests from different issues
130 enter the same area, both agents are told what the other is doing there.
1313. **When `main` moves: the author resolves.** Every open pull request is
132 trial-merged against the new `main`. A clean merge updates the pull request
133 silently. A conflict resumes that pull request's agent with its original
134 session and the incoming change, so the conflict is resolved by the agent
135 that wrote the code and still knows why.
1364. **At landing: a speculative queue.** Approved pull requests enter the
137 repo's queue. g1t builds the combined states (`main`+A, `main`+A+B, …) and runs
138 their checks in parallel. Pull requests land in order as their combined state
139 passes; one that fails is ejected back to its agent and the states behind
140 it are rebuilt. `main` only ever receives a state that passed.
141
142Landing can be fully automatic: a repo policy such as "checks pass and the
143reviewer agent approves" merges without a person.
144
145## Agents aware of each other
146
147Each repo keeps a live **work registry**: for every running pull request, its
148issue, a running summary of what it has done, and the files and symbols it
149has touched or plans to touch. Agents use it through MCP tools; g1t also
150acts on it without being asked.
151
152- **Before starting.** When an issue is opened, or an agent is about to
153 begin a task, g1t searches open issues and running pull requests for the same
154 goal (by meaning, not wording) and for the same area of code. If a match
155 exists the agent is told who is on it and how far along, and chooses: join
156 as a deliberate racer, wait for the result, or drop the task. Duplicate
157 issues are offered for merging.
158- **Finding out-of-scope work.** An agent that discovers something outside
159 its issue asks the registry who works there. If another pull request owns that
160 area, it **hands off**: a note, the relevant excerpt of its session, and
161 optionally commits the receiver can take. If nobody does, it opens a child
162 issue instead of widening its own change.
163- **Asking.** An agent can put a question or a request to another pull request.
164 The receiver gets it at its next turn.
165- **Waiting.** An agent that needs another pull request's result parks itself.
166 Its sandbox sleeps, spend stops, and it resumes from the new state when
167 that pull request merges.
168- **Agents that do not cooperate.** For pushes from tools that never call
169 these tools, g1t compares the pushed change against running pull requests and
170 flags near-duplicates itself.
171
172Every handoff, question and wait has a state (offered, accepted, declined,
173done), appears in the timeline, and is visible to people. A handoff declined
174twice, or two agents passing work back and forth, goes to the "needs you"
175inbox.
176
177## Review at scale
178
179Cloudflare's brief asks "how do you review everything they produce?". With
180hundreds of agents, a person cannot read every diff, so review is by
181exception.
182
183- **Evidence, not diffs.** Every pull request carries a proof bundle: checks run
184 and their output, a preview URL, a plain-language summary, and the
185 behaviour that changed.
186- **Two agent reviewers.** One reviews the change against the issue. A
187 second is adversarial: it tries to break the change and reports what it
188 found.
189- **Risk tiers.** Each change is scored from what it touches, how large it
190 is, and how the reviewers ruled. Low risk merges on policy; high risk goes
191 to a person with the evidence already assembled.
192- **Trust is earned.** An agent's record on a path (merged, reverted, caught
193 by review) raises or lowers the tier its changes land in.
194- **Sampling.** A share of auto-merged changes is sent to a person anyway,
195 to keep the policy honest.
196
197## Rethinking the git primitives
198
199- **No branches for agents.** A pull request is a fork; `main` is the only
200 long-lived line. There is nothing to name, clean up or go stale.
201- **Projected main.** New pull requests start from `main` plus everything already
202 in the landing queue, so they are built on the state they will land on.
203- **Structural merge.** The merge engine merges by syntax tree, not by line,
204 for supported languages. Two agents adding different functions to the same
205 file do not conflict.
206- **Forkable sessions.** A session can be forked at any turn: the code as it
207 was at that moment plus the conversation up to it, continued with a
208 different instruction. Branching applies to the reasoning as well as the
209 code.
210- **Provenance in history.** Every commit records its issue, session,
211 agent, model and cost, and is signed with a key issued to that pull request. The
212 history can be audited by machine.
213
214## People in the loop
215
216### Code that arrives from outside
217
218People will keep pushing with plain git, their editor, or another tool. Every
219push goes through g1t's git front end, so none of it bypasses the model.
220
221- **A push to a branch becomes a pull request.** g1t adopts it with the pusher as
222 author. A reviewer agent writes the issue it appears to serve and offers
223 to attach it to an open issue it matches. From there it gets the same
224 checks, compare view and queue as agent work.
225- **A push to `main` follows repo policy.** Protected: refused with a message
226 saying which ref to push to instead, so it enters the queue. Open: accepted
227 and treated as "`main` moved", which re-verifies the queue and triggers
228 resolve-on-move for every open pull request.
229- **Context is an open format.** A commit trailer names the session that
230 produced it, so any tool can attach its transcript. Commits without one are
231 shown in why-blame as "pushed by a person, no session".
232- **Approval rules.** Per repo and per path: merge automatically, require a
233 named person, or require a person when the change is large or the reviewer
234 agent is unsure.
235
236### Joining work that is already running
237
238- **Every session has a live page** that works on a phone: the transcript as
239 it streams, the current diff, check results.
240- **Steer.** Send a message, pause, or redirect. Hosted agents receive it
241 immediately; a person's own Claude Code receives it at its next turn
242 through the CLI hooks.
243- **Answer.** When an agent is blocked on a question, it appears in a "needs
244 you" inbox and as a notification. The answer resumes the agent.
245- **Take over and hand back.** Check out the pull request's fork, commit by hand,
246 push, and let the agent continue from there.
247
248### Planning by writing
249
250- **Brief.** Write the outcome in prose on the site, or commit it as a
251 markdown file. A planner agent turns it into a project: issues, each with
252 what done means, and dependencies. The person edits the graph before anything starts.
253- **Plan from their own agent.** The same operations are MCP tools, so a
254 person can plan in their own Claude Code session and create the project
255 from there.
256- **The brief stays the source of truth.** Editing it later re-plans: new
257 issues are added, obsolete ones are closed.
258
259### Seeing what moved
260
261- **Project page.** The outcome, the issue graph coloured by state, and how
262 many of its issues have landed with their required checks passing,
263 compared with when the project started.
264- **Digest.** An agent-written summary per project and per person: what
265 merged, what is blocked on whom, which conflicts were resolved, what it
266 cost.
267- **Timeline.** Every event (push, steer, check, conflict, merge) in order,
268 each linked to the session and the person or agent behind it.
269
270## One session, any surface
271
272A session belongs to g1t, not to the device it started on. The browser, a
273phone and Claude Code are views of the same session.
274
275- **Browser and phone.** The site is a responsive, installable web app with
276 push notifications. Everything a person does (brief, steer, answer,
277 approve, merge) works there.
278- **Claude Code.** Through `mcp.g1t.sh` and the CLI hooks, a local session is
279 a g1t session: its transcript syncs as it runs and it appears in mission
280 control like any other.
281- **Moving a session.** A local session can be sent to the cloud: a hosted
282 agent takes over the fork and the transcript and continues, so the laptop
283 can close. A hosted session can be pulled down: the CLI checks out the fork
284 and resumes it in local Claude Code with its history.
285- **Limit.** A session running only on a laptop stops when the laptop does.
286 It can be steered between turns but not continued until it is moved or the
287 laptop is back.
288
289## For people who do not write code
290
291- **Documents are first-class.** Specs, guides, policies and decisions live
292 in repos as markdown, shown in a Docs view: rendered pages, edited in the
293 browser like a document, with inline comments. "Suggest a change" is an
294 pull request and "publish" is merge, without git vocabulary.
295- **Document issues.** "Write the onboarding guide for the billing API" is
296 an issue. Its Definition of done is a checklist judged by a reviewer agent
297 instead of a workflow. Agents draft and revise; people comment and approve.
298- **Templates.** Product brief, RFC, decision record. A filled-in template is
299 a brief the planner can turn into a project.
300- **Explain.** Ask about any repo, project or change in plain language and
301 get an answer with links to the code and sessions behind it.
302- **Living documentation.** g1t generates "how this works" pages from the
303 code and keeps them current. When a merged change contradicts a document,
304 an issue opens to update it.
305- **See it, don't read it.** Every pull request on a deployable repo gets a
306 preview URL (Workers Builds from the pull request's fork), so an approver clicks
307 through the result instead of reading a diff. Changes are also summarised
308 in plain language.
309- **Roles.** Viewer, commenter, planner, approver: a person can plan and
310 approve work without ever cloning a repo.
311
312## The macro view
313
314The hierarchy above a single repo:
315
316| Level | What it is |
317| --- | --- |
318| **Workspace** | A company or team: its people, repos, agents, budget and policies. |
319| **Initiative** | A business outcome with an owner and measurable results, e.g. "move billing to usage-based pricing". Spans any number of repos. |
320| **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. |
321| **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. |
322
323How it feeds up, and what is built:
324
325- **A workspace is the unit everything belongs to.** Repositories, people,
326 access tokens, and later projects, budgets and policies are the
327 workspace's, never a person's. An account owns nothing; its first step
328 after confirming its email is creating a workspace, and the site sends it
329 there from wherever it was going.
330- **One namespace.** Usernames and workspaces share one set of names, as on
331 Docker Hub and npm. A username is reserved for its owner's workspace, so
332 `g1t.sh/<name>` never means two things.
333- **The workspace page is the roll-up.** `g1t.sh/<workspace>` shows its
334 repositories with their open issues and pull requests, and the pull
335 requests in progress across all of them. Projects and initiatives will
336 roll up to the same page. Its own pages live under `/<workspace>/-/`
337 (people, access tokens, settings), which no repository can be named.
338- **Workspace access tokens instead of service accounts.** A workspace has
339 tokens of its own, in the same table and code path as personal ones. One
340 acts as the workspace, with a member's rights in that workspace only,
341 records who made it and when it was last used, and keeps working when
342 that person leaves. CI, integrations and automations use these.
343
344### Portfolio
345
346One page answers "where is the business" across every initiative:
347
348- **Health** per initiative: on track, at risk, or blocked, derived from
349 facts (checks passing, issues stalled, questions waiting on a person),
350 not self-reported.
351- **Progress** as measurable results: required checks passing, issues
352 merged out of planned, and the trend since the start.
353- **Forecast** from actual throughput: at the current rate, when the
354 remaining issues land.
355- **Spend** in tokens and dollars against a budget, per initiative.
356- **Waiting on people**: every decision or approval a person owes, by name.
357- **Roadmap**: initiatives laid out as now, next, later, with optional
358 time-boxed cycles for teams that work in sprints.
359
360### Status without asking
361
362- **Standup.** An agent writes a daily report per initiative and one for the
363 whole workspace: what merged, what changed direction, what is at risk and
364 why, what needs a person. Delivered by email or webhook.
365- **Ask.** A question box over the full event log and all sessions: "what
366 happened on the billing migration since Monday?" answers with links to the
367 sessions and commits behind each claim.
368
369### Long-running agents
370
371Work that runs for days needs supervision that does not depend on someone
372watching.
373
374- **Checkpoints.** A long pull request reports milestones against its issue, so
375 progress is visible before anything merges.
376- **Stall and drift detection.** A pull request with no meaningful progress, or
377 whose changes have wandered away from its issue, is flagged and can be
378 stopped or re-briefed automatically.
379- **Budgets.** Hard limits on spend and time per pull request, project and
380 initiative.
381
382### Context hub
383
384Agents working across repos and days need context that outlives any one
385session and reaches beyond the code. The context hub is one place an agent
386asks, whatever the source.
387
388| Source | What it holds | How it gets there |
389| --- | --- | --- |
390| **Memory** | Decisions, conventions, gotchas, facts about systems | Written by agents and people in g1t |
391| **Code and sessions** | The repos, and the reasoning behind every change | Already in g1t |
392| **Connected sources** | Jira and Linear tickets, Notion and Confluence pages, Google Drive documents, Slack threads, Sentry issues | Connectors, authorised per workspace |
393
394How it behaves:
395
396- **One search.** An agent asks a question and gets ranked results across
397 all sources, each labelled with where it came from, who wrote it, and how
398 fresh it is.
399- **Connected sources stay where they are.** g1t indexes them for search and
400 fetches the current version when an agent opens one. The external system
401 remains the source of truth, and a link placed on an issue ("see
402 JIRA-482", a Notion URL) is pulled into the agent's starting context.
403- **Permissions carry over.** A connector only exposes what the connecting
404 account can see, and a workspace admin chooses which spaces, projects or
405 channels are included.
406- **External content is untrusted.** A ticket or page can contain text meant
407 to manipulate an agent. It is marked as reference material, never treated
408 as instructions.
409- **Documentation is separate.** Context is what agents know; documentation
410 is what people read, and it is generated from context and code.
411
412Memory is the part of the hub that g1t owns and agents write to:
413
414- **Memory is written freely.** Any agent or person adds an entry with one
415 call: a decision, a convention, a gotcha, a fact about a system. No review
416 gate. Each entry records who wrote it, from which session, and when.
417- **It is still a repository.** Each workspace has a memory repo in
418 Artifacts, so every write is a commit: versioned, attributable, and
419 revertible.
420- **It is kept healthy by an agent.** A consolidation agent merges
421 duplicates, retires entries that newer ones contradict, and flags
422 conflicts it cannot settle. People can pin an entry (agents may not change
423 it), correct it, or retract it.
424- **Agents read it.** Every session starts with the context relevant to its
425 issue, found by search, and can query more through MCP.
426- **Updates are events.** A memory write or a change in a connected source
427 is an event, so "when context changes, update the affected docs" is an
428 automation, on by default.
429- **It is scoped inside the workspace.** Some context applies to the whole
430 workspace, some to one initiative, project or repo, so an agent gets what
431 applies to its work.
432- **It never crosses workspaces.** A workspace is the isolation boundary: its
433 context, sessions and private repos are invisible to every other
434 workspace, and an agent's token is bound to one workspace.
435
436## Working in g1t
437
438- **Mission control.** The signed-in home page: every running session, every
439 issue waiting on a decision, and what merged, across all repos.
440- **Outcomes.** Group issues across repos toward one result and track how
441 many are open, racing, or merged. (What [Projects](#projects) means is
442 below.)
443- **Steering.** Send a message to a running pull request, or to all pull requests on an
444 issue at once, without stopping them.
445- **Automations.** Rules that start work without a person (next section).
446
447## Automations and integrations
448
449> **2026-10-03:** g1t's own `.g1t/automations` format was built and then set
450> aside at the user's request ("let's just copy GitHub Actions on that for the
451> time being"). Automation on g1t is GitHub Actions workflows in
452> `.g1t/workflows/`; the format below is kept for later.
453
454An automation is **when** an event happens, **if** conditions hold, **do**
455something. They are defined as files in the repo (`.g1t/automations/`), the
456way GitHub Actions workflows are, and can also be built in the UI.
457
458### Events that can trigger one
459
460| Source | Examples |
461| --- | --- |
462| Git | push, merge, check failed, `main` moved |
463| g1t | issue opened, pull request stalled, context updated, handoff declined, budget reached |
464| Time | cron schedule |
465| Integrations | Sentry issue, PagerDuty incident, Linear or Jira ticket, Slack message or mention, GitHub issue, Stripe event |
466| Anything else | a signed generic webhook, or an email to a per-repo address |
467
468**Actions**: open an issue (optionally assigning N agents to it), message
469a running pull request, update documentation, notify, call a
470webhook, write back to the source system.
471
472**Example: Sentry.** A new production error arrives. The automation opens an
473issue labelled `bug`, with the stack trace, release and frequency in its
474description. Why-blame
475finds the session that wrote the failing line, so the fixing agent starts
476with the original reasoning. When the fix merges, g1t comments on the Sentry
477issue and resolves it.
478
479### Rules every automation obeys
480
481- **Deduplication.** The same Sentry issue firing 500 times maps to one
482 issue.
483- **Limits.** Concurrency and budget caps per automation.
484- **Loop protection.** Work started by an automation cannot retrigger the
485 same automation without a person in between.
486- **External input is untrusted.** A webhook payload can contain text written
487 by an attacker. Agents started by external events run with reduced
488 permissions and cannot merge without the repo's approval rule passing.
489
490**Checks** are the other half of what GitHub Actions does: build and test
491commands declared in `.g1t/checks.yaml`, run in sandboxes on every pull request
492and on every combined state in the landing queue.
493
494Agents can also reach integrations directly: an agent definition lists MCP
495servers (Sentry, Linear and so on) it may use while working.
496
497## A repository that maintains itself
498
499> **2026-10-04:** the user asked for Dependabot, GitHub Advanced Security and
500> Vercel-style deployments, "so you're not having to maintain shit and you're
501> just pushing up agents that are delivering work consistently".
502
503GitHub reports problems and leaves the fix to you. In g1t, an agent opens an
504issue for each problem, writes the fix, runs its checks, links a preview and
505lands it through the queue. People only decide.
506
507### Upkeep agents
508
509- **Dependency updates.** A scheduled scan reads the lockfiles (npm, Cargo,
510 Go, pip), finds outdated and vulnerable packages and opens one issue per
511 update or group, assigned to g1t-agent. The agent upgrades the package,
512 fixes what the upgrade broke and lands it through the queue. A repository
513 sets how often it scans, which packages it groups and what lands without
514 review (`.g1t/upkeep.yml`, shaped like `dependabot.yml`).
515- **Secret scanning.** Pushes are scanned for known token formats. A push
516 that adds a secret is refused with the file and line; one already in
517 history opens an issue to rotate it and remove it.
518- **Vulnerability alerts.** Dependencies are matched against the OSV
519 database. Every alert links to the issue and pull request fixing it.
520- **Code scanning.** A reviewer agent reads each pull request's diff for
521 security problems and leaves findings as review comments with a
522 suggested fix. Findings on `main` open issues.
523- **A security page per repository** lists alerts, secrets and findings,
524 with the agent work on each, like GitHub's Security tab.
525
526All of these are event sources for the existing issue → agent → checks →
527queue pipeline; they need no new kind of work.
528
529### Deployments
530
531- **A preview for every pull request**, at
532 `<pr>--<repo>--<owner>.g1t.page`, linked on the pull request and updated
533 on each push. `main` deploys to `<repo>--<owner>.g1t.page`, and a
534 repository can add its own domain.
535- **On g1t.page, not g1t.sh,** so customer code never shares cookies or an
536 origin with the site people sign in to.
537- **Built on Workers for Platforms.** Each deployment is a user Worker in a
538 dispatch namespace; one dispatch Worker on `*.g1t.page` routes to it. The
539 build runs in the same runners as Actions. Static sites and Workers apps
540 first; container apps and databases later.
541- **Agents use the preview.** The reviewer agent opens the preview in a
542 browser, takes screenshots of what changed and attaches them to its
543 review, so an approver sees the result without reading the diff.
544- **Environments.** Preview, production and their secrets; deploy history
545 and one-click rollback.
546- **Scale to zero.** An idle branch costs neither g1t nor the customer
547 anything: a Worker runs, and is billed, only while it answers a request.
548 A preview is deleted when its pull request closes or merges, and after
549 a set number of idle days. Container apps, later, sleep when idle.
550- **Billed to the customer, never free.** The user (2026-10-04): "we
551 should not be giving any of this available for free". Every deployment
552 is metered per workspace (requests, CPU time, deployed apps, stored
553 data), priced at Cloudflare's cost + 20% like agent usage, and drawn
554 from prepaid credit. `FREE_WHILE_BUILDING` and the free model allowance
555 do not cover deployments: a workspace without credit cannot deploy, and
556 turning deployments on says so first.
557- **Turning them on is a paid plan, the way Cloudflare's is.** "Including
558 things like them even enabling the feature should have that pay like
559 Cloudflare does." Enabling deployments for a workspace starts a monthly
560 fee that includes an allowance of requests, CPU time and deployed apps;
561 usage past it is billed per unit, as Workers for Platforms bills g1t.
562 The fee and allowance are the user's to set.
563- **Recommended, off in one click.** Because enabling costs money, it is
564 never switched on without the workspace agreeing: new repositories
565 recommend it prominently. A repository can turn it off, keep only production, or
566 deploy somewhere else from its own workflows. Apps built for Cloudflare
567 (Workers, static assets, D1, KV, R2) deploy without configuration.
568
569Later, toward GitLab's DevOps breadth: environment protection rules,
570package and container registries, releases, container hosting.
571
572## Projects
573
574> **2026-10-04:** the user: "an extra dimension of Projects so it's not
575> just repositories … where a lot of things can live", "very Vercel
576> like", with dependencies across projects "the Platform Engineering /
577> Port route", and "the repository is *part* of a project: you could be
578> mirroring it from GitHub/GitLab/Bitbucket, or you could let us host it
579> for you", with room for Mercurial or anything else later.
580
581**A project is the thing you are building and running; a repository is
582where some of its code lives.** Everything that is about running software
583(deployments, environments, domains, secrets, dependencies, owners,
584health, upkeep) belongs to the project. What is about the code itself
585(branches, pull requests, review, merge rules) stays with the repository.
586That split is what lets the code live anywhere.
587
588### The model
589
590| | What it is | Like |
591| --- | --- | --- |
592| **Workspace** | The company or team. Members, billing, plans, shared secrets. | Vercel team, GitLab group, GitHub org |
593| **Group** | An optional named set of projects, one level: "Payments", "Mobile". For browsing, ownership and shared settings. | GitLab subgroup, Backstage system, Port domain |
594| **Project** | One deployable thing: a site, an API, a worker, a library. Has exactly one **source**. | Vercel project, Port service, Backstage component |
595| **Source** | Where its code is: a repository and a **root directory** in it. | Vercel's connected repo + root directory |
596| **Dependency** | Project A uses project B: calls its API, consumes its package, reads its queue. | Port relations, Backstage `dependsOn` |
597
598- **One project, one source; one repository, any number of projects.** A
599 project builds from exactly one place, which keeps it as simple as
600 Vercel's. A monorepo is several projects on one repository, each with
601 its own root directory (`apps/web`, `services/api`), and a push builds
602 only the projects whose root it touched. The common case stays 1:1, and
603 every existing repository gets a project of its own name when this
604 ships, so nobody has to set anything up.
605- **Groups are for people; dependencies are for software.** Groups decide
606 where a project shows up and who owns it. Dependencies decide what
607 happens when one changes. Neither replaces the other, and a dependency
608 can cross groups.
609
610### Sources: where the code lives
611
612A source is an adapter behind one interface (`SourcePort`: clone URL,
613branches, commits, pushes as events, pull requests if it has them):
614
615| Source | Code lives | g1t gets pushes by | Pull requests |
616| --- | --- | --- | --- |
617| **Hosted on g1t** (today) | Artifacts | its own events | g1t's, with agents, the queue, review |
618| **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 |
619| **Connected, not copied** | The provider only | webhook | The provider's |
620| **Later:** Mercurial, Perforce, a tarball upload | Behind the same port | per adapter | per adapter |
621
622A mirrored or connected project still gets everything that is the
623project's: previews on its pull requests (a status and a comment on
624GitHub's), production on its default branch, secrets, dependencies,
625upkeep agents. That is the on-ramp: a team keeps GitHub and gets g1t's
626deployments and agents first, and moves the code later or never.
627Bring-your-own-git is also why the project, not the repository, holds the
628URL `g1t.sh/<workspace>/<project>`.
629
630### What lives on a project
631
632| | Today it is on | Moves to the project |
633| --- | --- | --- |
634| Deployments: production, previews, build settings, root directory, framework | The repository | Yes |
635| Environments: production, preview, and custom ones (`staging`) with protection rules (required approvers, branch limits) | Nowhere yet | New, on the project |
636| Domains: `<project>--<workspace>.g1t.page`, and custom domains | The repository's name | Yes |
637| 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). |
638| Dependencies | Nowhere | New |
639| Owners, on-call, links (docs, dashboards, runbooks) | Nowhere | New: the catalog's metadata |
640| Health: scorecards (has an owner, CI passes, dependencies current, no open security alerts, deploys within N days) | Nowhere | New |
641| Upkeep agents: dependency updates, security alerts | The plan | Scoped per project |
642| Logs and analytics of the running app | Nowhere | New: requests, errors and CPU per environment, from Workers analytics |
643| Branches, pull requests, review, merge rules, the queue, webhooks | The repository | Stay |
644
645### Dependencies: why this gets powerful
646
647Declared in the UI, or in the source as `.g1t/project.yml` (which wins
648when present, as `catalog-info.yaml` does in Backstage):
649
650```yaml
651name: web
652root: apps/web
653dependsOn:
654 - project: api # calls its HTTP API
655 as: API_URL # its URL, per environment, as a variable
656 - project: ui-kit # consumes its package
657```
658
659What g1t does with them:
660
6611. **Reference variables.** `API_URL` above resolves to `api`'s production
662 URL in production and to the matching preview in a preview, the way
663 Railway's `${{ api.URL }}` references work. No hard-coded URLs.
6642. **Preview stacks.** A pull request on `api` gets its own preview, and
665 **Preview with dependents** builds `web`'s preview pointed at it, so a
666 reviewer clicks through the whole change across projects. A change that
667 spans repositories (one issue, one fork per repository) gets one stack.
6683. **Release order.** Production deploys go out in dependency order; a
669 change set across projects lands through the queue together or not at
670 all.
6714. **Impact on every pull request.** "Changes `api`; `web` and `mobile`
672 depend on it." Agents get the graph in their context: an agent
673 changing an API opens follow-up issues on the projects that call it,
674 and reviewers see what else could break.
6755. **Upkeep across the graph.** A vulnerable package in `ui-kit` opens
676 issues, assigned to agents, on every project that consumes it.
6776. **Scorecards turn into work.** A project failing a scorecard check
678 ("no owner", "dependencies 90 days old") gets an issue an agent can fix.
679 That is the Port idea with the work done for you.
6807. **The map.** A workspace's projects as a graph, coloured by health and
681 by what is deploying now.
682
683### Pages
684
685- `g1t.sh/<workspace>`: projects first (grouped, with health and
686 production status), then repositories.
687- `g1t.sh/<workspace>/<project>`: overview (production, latest previews,
688 health, owners, dependencies both ways), **Deployments**,
689 **Environments**, **Secrets and variables**, **Logs**, **Settings**
690 (source, root directory, build, domains, groups, owners).
691- A hosted repository keeps its code pages; from a project they are its
692 **Code** tab. A repository page lists the projects built from it.
693
694### Services
695
696- `services/projects` (new): projects, groups, sources, dependencies,
697 owners, scorecards. Events `project.created`, `project.updated`,
698 `dependency.changed`.
699- `services/deployments`: keyed by project instead of repository.
700- Secrets and variables: the scope becomes workspace → project.
701- Sources: the hosted adapter wraps `services/repos`; a mirror adapter
702 per provider in `services/integrations`, which already holds those
703 connections.
704
705### Build order
706
7071. **Projects as the home of deployments and secrets**, 1:1 with every
708 existing repository: the service, the pages, deployments and secrets
709 moved to the project, `<project>--<workspace>.g1t.page`.
7102. **Dependencies:** declared in the UI and `.g1t/project.yml`, reference
711 variables, impact on pull requests and in agents' context, the map.
7123. **Preview stacks** and cross-project change sets.
7134. **Monorepos:** several projects on one repository, each with a root
714 directory, building only what a push touched.
7155. **Mirrored sources:** GitHub first, then GitLab and Bitbucket.
7166. **Groups, owners, scorecards** feeding the upkeep agents.
7177. **Environments** with protection rules; custom domains; logs.
718
719**Step 1 shipped 2026-10-04:** `services/projects`; every repository a
720project of its own name; the site projects-first (workspace page of
721project cards, the project overview at `g1t.sh/<workspace>/<project>`, code
722under `/code`, the sidebar and the New project flow); deployments keyed by
723project and branch at `<project>-<workspace>.g1t.page` and
724`<project>-git-<branch>-<workspace>.g1t.page`; secrets and variables owned
725by the project.
726
727**Step 5, GitHub, built 2026-10-05:** one GitHub App (`g1t-sh`) for both
728sign-in and repository access. Sign-in is its user authorization with PKCE
729(identity, `src/github.rs`): accounts known by GitHub's numeric id, a
730matching verified email never linked without signing in to the account,
731new accounts behind the invite check. Repositories come through its
732installations (integrations, `src/github.rs`), copied with every branch and
733tag by the repos service (`src/mirror.rs`) as **import**, **mirror** (g1t
734follows GitHub on its push webhook) or **move to g1t** (GitHub follows g1t
735on `git.push`). A mirror is a hosted repository that keeps a full copy, so
736its project stays `hosted` and deploys like any other; the tie lives in
737integrations' `github_repos`. Not yet: previews and statuses on GitHub's own
738pull requests, comments and pull requests copied, GitLab and Bitbucket.
739
740### People and search
741
742> **2026-10-04:** "pull up user profiles, using a /u/username prefix kinda
743> like DockerHub … search for users if you search that explicitly, how
744> GitHub has the aside for searching against filters … a significantly
745> stronger implementation."
746
747- **Profiles at `g1t.sh/u/<username>`**, apart from workspaces at
748 `g1t.sh/<workspace>`: who they are, their workspaces, recent work,
749 agents' sessions they steered.
750- **Search with a filter sidebar:** Projects, Code, Issues, Pull requests,
751 Users, Workspaces, each with its count; filters by workspace, language,
752 state, author, agent, label, date; qualifiers in the query
753 (`user:`, `is:open`, `agent:g1t-agent`) as on GitHub. Typing `u/name`
754 searches people directly, as Docker Hub does.
755
7561 and 2 serve the competition directly (multi-agent coordination across
757projects is 25% of the score); 3 is the demo's best moment if time allows.
758
759## Billing model
760
761> **2026-10-04:** "Some things just require you to have a card on file …
762> some things will be something you give us an initial amount of money
763> per month just to activate, tons of things additionally will be usage
764> based, some things will just be usage based only … at minimum a
765> breakeven with Cloudflare costs, or in some cases a value add." Stripe
766> moves to Flagon, Inc. (g1t.sh is its product). Proposed below; the
767> prices are the user's to confirm.
768
769### Four kinds of charge
770
771Every feature is exactly one of these, and the Billing page says which:
772
773| Kind | What the workspace does | Example |
774| --- | --- | --- |
775| **Free** | Nothing | Hosting code, issues, pull requests, review, the merge queue, bringing your own agent over MCP |
776| **Card on file** | Adds a card; pays only for what it uses | Previews, g1t's agents, workflow minutes |
777| **Activation** | Turns a feature on for a monthly fee that includes an allowance; usage past it is metered | Production deployments, Security and quality |
778| **Usage only** | Nothing up front; every unit is metered | Model tokens, build minutes, storage past the free amount |
779
780A card is needed before anything that can cost money starts. Nothing is
781ever switched on without the workspace choosing it.
782
783### Postpaid, with spend limits
784
785- **One Stripe customer and one subscription per workspace**, on Flagon,
786 Inc.'s account. Activations are licensed line items; every usage
787 dimension is a metered price backed by a Stripe Meter. Stripe invoices
788 monthly in arrears and charges the card on file; failed payments go
789 through Stripe's retries and emails, and g1t hears of them by webhook.
790- **Spend limits instead of prepaid credit.** A workspace sets a monthly
791 limit overall and per feature (Vercel's spend management). g1t counts
792 usage as it happens and stops starting new paid work at the limit,
793 with a warning at 50%, 80% and 100%. Prepaid top-ups go away; promotions
794 (the free model allowance) become Stripe credit on the customer.
795- **Usage reaches Stripe from billing alone.** Every service reports
796 usage to the billing service as it happens (it already records agent
797 runs and builds); billing batches them into Stripe meter events every
798 few minutes, idempotently by g1t's own ids, and keeps the ledger g1t's
799 pages show. Nothing else talks to Stripe.
800
801### Scope: workspace, then projects
802
803- A feature is turned on for the **workspace** (by an owner, with the
804 activation if it has one), then allowed for **all projects** or
805 **selected projects**.
806- Every **project** can opt out on its own page. A project with nothing
807 to deploy (no Workers config, no build script, no `index.html`) is
808 detected, says so on its Deployments page, and never builds or costs
809 anything.
810- Agents and workflows are allowed per project the same way, so a
811 workspace can keep spend to the projects that matter.
812
813### Prices: what it costs us, passed through
814
815> **2026-10-04, decided:** postpaid with spend limits, as Vercel and
816> Cloudflare do; no per-seat price, ever ("fuck per-seat pricing").
817> "If they're barely using them great, but if they're using the shit out
818> of them that will cost me a ton, so that cost needs to move onto them."
819
820**Every Cloudflare cost a workspace causes is metered to it.** Light use
821fits in a small free allowance; past it, each unit is charged at
822Cloudflare's price times a margin of at least 1.5, which pays for Stripe
823(about 3%), shared overhead (the site, the API, D1) and g1t itself.
824
825Cloudflare's prices (October 2026), and the cost per unit g1t meters:
826
827| What g1t meters | Cloudflare's price | Cost to g1t per unit |
828| --- | --- | --- |
829| **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) |
830| **App request** (deployments) | Workers for Platforms: $0.30 / million past 20M | $0.30 / million |
831| **App CPU** | $0.02 / million CPU-ms past 60M | $0.02 / million ms |
832| **App** (a deployed script) | $0.02 / script-month past 1,000 | $0.02 / app-month |
833| **Storage** (repositories, artifacts, caches) | Artifacts $0.50 / GB-month (billing starts 2026-10-14); KV $0.50 / GB-month | $0.50 / GB-month |
834| **Git operation** (clone, fetch, push) | Artifacts $0.15 / 1,000 past 10,000 | $0.15 / 1,000 |
835| **Model tokens** | The provider's price | As charged |
836| Container egress, emails, the site's own requests | Small and shared | In the margin |
837
838> **2026-10-06, decided:** no per-feature quotas on the plan. "A paying
839> user should be able to push past the Git operations number, they're
840> just paying usage on it." One plan, $20 a month per workspace with $10
841> of usage included; every meter is charged from the first unit at cost +
842> 20% (builds, app requests and CPU, custom domains), drawn from the $10
843> first, then up to the spend limit, which is the only thing that stops a
844> paying workspace (with abuse protection). Projects, previews and apps
845> are not metered (Workers for Platforms' script pool makes them ~free).
846> The forge's free amounts are the same for everyone: 1 GB private storage
847> and 50,000 git operations a month; past them the plan pays and a free
848> workspace is held (pushes stop, git slowed). The table below is the
849> earlier proposal; billing's price book and g1t.sh/pricing are current.
850
851What a workspace pays:
852
853| Meter | Free each month | Then | Margin | For comparison |
854| --- | --- | --- | --- | --- |
855| 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 |
856| App requests | 1 million with Deployments | $0.50 / million | 1.7× | Vercel $0.60 / million invocations |
857| App CPU | 3 million ms with Deployments | $0.04 / million ms | 2× | Vercel active CPU about $0.036 / million ms |
858| Apps | 10 with Deployments | $0.05 / app-month | 2.5× | |
859| Storage | 1 GB | $1.00 / GB-month | 2× | GitHub LFS $0.07 / GB, but repositories are free there |
860| Git operations | 10,000 | $0.30 / 1,000 | 2× | |
861| g1t's models | | Cost + 20% | 1.2× | The provider's own price |

864| **Security and quality** activation (later) | | $10 / month; fixes as agent usage | | GitHub Advanced Security $49 per committer |
865
866A workspace that uses g1t lightly (a few agent runs, a small site)
867pays nothing or its activation; a workspace running agents all day pays
868for the sandboxes and models those agents use, with g1t's margin on
869each. Nothing in a workspace's bill is subsidised by another's.
870
871### Build order
872
8731. Stripe customer per workspace and card on file (Checkout in setup
874 mode), webhooks (invoice paid and failed, subscription changes,
875 payment method changes), the Billing page rebuilt around the four
876 kinds.
8772. One subscription per workspace with activations as items; Deployments
878 moves onto it.
8793. Meters for each usage dimension above, fed from billing's ledger:
880 every sandbox reports how long it ran when it stops (agents, checks,
881 the queue, workflow jobs and deploy builds alike); deployments report
882 requests, CPU and apps; repos report storage and git operations. Spend
883 limits and their warnings; prepaid credit retired.
8844. Per-workspace allow-lists of projects for each feature, and per-project
885 opt-out; "nothing to deploy" detection.
8865. Turn off FREE_WHILE_BUILDING when the user says so. **Done 2026-10-05.**
887
888Shipped by 2026-10-05: sandbox seconds for every sandbox; the price book
889and its keeper (runs settled to AI Gateway's price every 15 minutes;
890Container and Workers costs checked against Cloudflare's billable usage
891and container analytics daily, with a public change log on
892g1t.sh/pricing); usage limits by trust with automatic payment near the
893limit; app traffic counted toward limits as it happens; billing accounts,
894terms and enterprises; free mode off, syntaqx comped.
895
896Still to build, in order: Stripe card-on-file without a payment (setup
897mode) and webhooks; month-end invoices for postpaid usage (and one
898invoice per enterprise); the subscription with activations as items;
899storage and git-operation meters; limit warnings by email at 50/80/100%;
900self-serve enterprise management for enterprise owners.
901
902### Accounts, terms and enterprises
903
904Every workspace is paid for by a billing account: its own (`ws_<slug>`)
905or an enterprise's (`ent_…`), which pays for several workspaces with one
906limit, one set of terms and, once invoices exist, one bill, as GitHub
907Enterprise does. Terms are standard, comped (nothing charged, usage still
908recorded at cost, paid features on) or custom (a discount, its own
909ceiling, an end date). g1t staff manage them in **sudo.g1t.sh**, a
910separate Worker behind Cloudflare Access that also verifies the Access
911token itself and allows only listed staff emails; every change is kept
912with who made it and why.
913
914### Limits: stop non-payers, never payers
915
916The limit is on usage not yet paid for, counted at cost to g1t or charge,
917whichever is more: $3 before any live payment, then twice what has been
918paid ($25 to $1,000), or what staff set. A workspace with a card on file
919is charged automatically near its limit, which both pays what it owes and
920raises the limit, so paying users are never stopped. A declined card
921stops work until paid. The owner's own spend limit always means stop.
922Test-mode payments never lower exposure or raise trust.
923
924## Agents and models
925
926### Defining an agent
927
928An agent is a file (`.g1t/agents/<name>.md`, or in the workspace library):
929instructions, the harness and model to run, the tools and MCP servers it may
930use, its sandbox image, permissions and budget. Agents take roles: planner,
931implementer, reviewer, conflict resolver, documenter, memory consolidator.
932Each role has a default that a repo can replace.
933
934### Where it runs, and on whose model
935
936| Option | How it works | Fits |
937| --- | --- | --- |
938| Hosted, g1t's model | g1t runs the sandbox and bills usage | Getting started; no keys to manage |
939| Hosted, your API key | Same sandbox, your Anthropic, OpenAI or Google key | Teams with existing contracts |
940| Hosted, your endpoint | Any OpenAI-compatible URL: Bedrock, Vertex, Azure, a self-hosted model | Private or fine-tuned models |
941| Your runner | A g1t runner daemon on your own machines picks up pull requests | Code or models that may not leave your network |
942| Your own session | Local Claude Code, Cursor or any MCP client joins through `mcp.g1t.sh` | Individuals; subscription plans |
943
944Decisions behind this:
945
946- **g1t does not build its own agent loop.** It runs existing harnesses
947 (Claude Code first, through its headless mode) behind a small runner
948 contract: a container image, an entry command, and session events reported
949 through the CLI. Other harnesses plug in by meeting the contract.
950- **All hosted model traffic goes through Cloudflare AI Gateway.** That gives
951 one place for spend tracking, budgets, rate limits, fallback and logs,
952 whichever provider or endpoint is behind it.
953- **Nobody picks a model.** A person assigns work to `g1t-agent`, as they
954 would assign an issue to Copilot, and g1t routes it. Today the kind of
955 work decides (implementing, reviewing, catching up), from one setting on
956 the runner, and each request is tagged at the gateway with that kind, the
957 repository and the pull request. The session records which model ran.
958 The gateway's own dynamic routes cannot make the choice yet: they work
959 only on its OpenAI-compatible endpoint, and the harness speaks
960 Anthropic's.
961- **Subscriptions stay local.** A Claude subscription cannot be used by a
962 hosted sandbox; it needs an API key. People on subscriptions use their own
963 Claude Code session, which is a full participant.
964- **The workspace pays.** A workspace buys credit by card and each agent
965 run deducts what the model cost plus a margin. The billing service asks
966 nothing of the others: the runner asks it before starting a sandbox and
967 is refused when there is no credit, and the sandbox reports what its run
968 cost with a token only it holds. Where no card processor is configured
969 nothing is charged and agents stay limited to listed accounts.
970- **Keys are secrets.** Stored in Cloudflare Secrets Store, injected into the
971 sandbox for one pull request, never shown again.
972
973### Seeing a pull request through
974
975Assigning an issue is the only thing a person does until there is something
976to merge. A pull request made by a g1t agent goes through checks, a review
977by another agent, revision when either finds something, and catching up
978when `main` moves, without anyone pressing a button. It ends as ready to
979merge, or as "needs you" with the reason: the checks still fail after two
980revisions, a review could not be written, or a conflict could not be
981resolved.
982
983The work service decides the next step from the pull request's state and
984claims it in one statement, so a step is taken once. The runner asks on
985every event that could change the answer (ready, pushed, checks finished,
986review finished, `main` moved), and on a five-minute sweep for anything
987missed, and carries the step out in a sandbox.
988
989A pull request does not have to be up to date with `main` to merge,
990unless the repository's settings require it, as on GitHub. Merging one that
991is behind brings it up to date first (a clean merge needs no model; an
992agent resolves a conflict) and lands it when that push arrives. With the
993requirement on, catching up is a step of its own and the checks run again
994on the result.
995
996Each repository sets its own rules, on one settings page: whether its
997default branch takes pushes at all, how many approvals a merge needs and
998whether an agent's counts, whether failed checks can be overridden, whether
999a second agent reviews, and how often an agent is sent back before a person
1000is asked. A g1t agent's pull request follows the same rules as anyone's.
1001Pushes to a protected branch are refused in the git front end, with the
1002reason shown by git beside the branch.
1003
1004Merging is a person's decision unless the repository says otherwise. With
1005"merge automatically when ready" turned on in its settings, a ready pull
1006request lands by itself, attributed to `g1t`. That is the whole path from
1007an assigned issue to a commit on `main` with nobody in between. Required
1008human approval per path, and risk tiers, are still to come.
1009
1010### Choosing the right agent automatically
1011
1012Because several agents can work on the same issue, every issue with more
1013than one pull request is an evaluation on real work. g1t records, per repo and per kind of issue, each
1014agent's win rate, cost and time. That produces a leaderboard, and a routing
1015policy: send each new issue to the agent that wins that kind most often,
1016start with the cheapest that is good enough, and escalate to a stronger one
1017when checks fail.
1018
1019## Talking: the inbox and channels
1020
1021Not a discussions forum. People and agents need one place to talk in real
1022time, and an app that feels like one on desktop and phone.
1023
1024**The inbox comes first.** Everything that needs a person or that they
1025follow, from people and agents: review requests, agent questions and
1026handoffs, failures, mentions, deploys. Read and unread, saved, done,
1027snoozed; ranked so what an agent is blocked on comes first; email digests
1028and push. It is the delivery layer chat needs too (who is told what, read
1029state, push), so building it first makes channels cheap.
1030
1031**Channels** (working name): workspace channels, direct messages and
1032threads, live.
1033
1034- Each channel is a Durable Object holding its WebSocket connections with
1035 hibernation, so idle channels cost nothing; history in D1, files in R2.
1036- Agents are members. `@g1t-agent` in a channel starts work, answers, or
1037 posts a summary; agents post their questions and handoffs where people
1038 already are. A thread becomes an issue or an outcome in one action, and
1039 the agent's progress streams into that thread.
1040- Tied to the work: issues, pull requests, runs and deploys each have a
1041 thread; links unfurl into live cards (checks, agent step, preview).
1042 What a channel settles can become workspace memory, with its source.
1043- Apps: an installable PWA first (desktop and mobile, offline shell, Web
1044 Push), then native shells on the same API: Tauri for desktop (tray,
1045 deep links), React Native for iOS and Android (background
1046 notifications).
1047
1048GitHub-style Discussions are not planned: channels and threads on the
1049work replace them.
1050
1051## What GitHub ships today, and where g1t differs
1052
1053GitHub's Agent HQ and Copilot app give each agent session its own git
1054worktree and branch, list sessions in a mission-control view grouped by
1055project, and let a task be assigned to several agents so their output can be
1056compared. Underneath, the unit of work is still a branch and a pull request.
1057
1058| | GitHub | g1t |
1059| --- | --- | --- |
1060| 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 |
1061| Agent context | Lives in the app's session view | Stored with the repository and linked from each commit (why-blame) |
1062| 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 |
1063| Collisions between agents | Found as merge conflicts at the end | Flagged during the work (overlap radar) |
1064| Landing changes | One pull request at a time | A merge queue that lands the chosen one and closes the rest as superseded |
1065| Which agents | Those offered through a Copilot subscription | Any MCP client, plus hosted agents |
1066
1067## How agents connect
1068
10691. **Bring your own agent.** A remote MCP server at `mcp.g1t.sh` lets Claude
1070 Code (or any MCP client) list issues, claim one, get a clone URL and
1071 token, report progress and submit. Adding it is one command; sign-in is a
1072 browser OAuth flow with no token to paste. The `g1t` CLI installs Claude
1073 Code hooks that upload the session transcript as the agent works.
10742. **g1t agents.** Assign an issue to g1t's own agent, or many issues at
1075 once, each to an agent of its own. g1t starts a sandbox for each
1076 (Cloudflare Containers), running a coding agent headless against its
1077 own pull request and fork.
10783. **API and CLI.** Everything above is available at `api.g1t.sh` and
1079 through `g1t`.
1080
1081## Public surfaces
1082
1083| Host | What it serves |
1084| --- | --- |
1085| `g1t.sh` | The site, git over HTTPS, git over SSH |
1086| `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 |
1087| `mcp.g1t.sh` | Remote MCP server over streamable HTTP |
1088
1089g1t is its own OAuth 2.1 authorization server: authorization code with PKCE,
1090dynamic client registration that stores nothing (a client id encodes its
1091own registration, so the open endpoint cannot be used to fill a database),
1092discovery metadata and rotating refresh tokens. Still to come: scopes
1093per resource (`repo:read`, `repo:write`, `issue:write`, `pull:write`).
1094MCP clients, the CLI (device flow) and third-party apps all use it. Access
1095tokens and SSH keys remain for git itself.
1096
1097## Architecture
1098
1099| Component | Language | Runs on | Responsibility |
1100| --- | --- | --- | --- |
1101| `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. |
1102| `services/identity` | Rust | Worker + D1 | Accounts, workspaces and memberships, sessions, SSH keys, access tokens, device sign-in, OAuth codes and grants |
1103| `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. |
1104| `services/work` | Rust | Worker + D1 | Issues, pull requests, comments, sessions; later a Durable Object per repo for the landing queue and live state |
1105| `services/billing` | Rust | Worker + D1 + Stripe | Each workspace's agent credit: payments, the ledger of every run, and the gate on starting one |
1106| `services/events` | Rust | Worker + Queues + D1 | The event bus: durable log, and one queue per subscribing service |
1107| `services/runner`, `crates/runner` | TypeScript, Rust | Worker + Containers | Starts a sandbox per g1t agent; the program inside runs the agent harness and reports through the public API |
1108| `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 |
1109| `apps/web` | TypeScript | Worker | Server-rendered site. Holds no data; calls services over RPC. |
1110| `apps/docs` | TypeScript | Worker (static) | Documentation and the API explorer |
1111| `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 |
1112| `crates/sshd` | Rust | Container | Git over SSH, bridged to Artifacts |
1113| `crates/merged` | Rust | Container | Trial merges, conflict matrix, landing merges (needs real git; the Artifacts binding is read-only) |
1114| `crates/core` | Rust | native and WASM | pkt-line, packfile and diff code shared by the above and by the Worker |
1115| `crates/g1t` | Rust | user's machine | CLI: auth, SSH proxy, Claude Code hooks, issues and pull requests |
1116
1117Storage: Artifacts for repositories (one fork per pull request), D1 for accounts
1118and metadata, R2 for session transcripts and logs, Durable Object SQLite for
1119per-repo coordination state.
1120
1121How the services fit together:
1122
1123- **Each service is its own Worker with its own database.** It deploys,
1124 scales and fails on its own. Callers reach it through a typed RPC binding
1125 to the interface in `packages/contracts`.
1126- **Expected failures are values.** Every call returns a `Result`, so "not
1127 found" or "forbidden" crosses a service boundary as data.
1128- **Side effects travel as events.** A service publishes what happened
1129 (`git.push`, `issue.opened`, `pull.merged`, …) to the bus and does not
1130 call other services to react. Each subscriber consumes from its own queue.
1131 Timelines, webhooks and automations read the same stream, which is what
1132 lets something like GitHub Actions be built on top.
1133- **Every read takes the viewer.** Authorization is decided inside the
1134 service that owns the data, not by its callers.
1135
1136The Workers runtime scales request handling on its own, so the edge layer
1137stays in TypeScript. Rust is used where there is real computation or a real
1138protocol to implement.
1139
1140## Languages
1141
1142The site is TypeScript. Everything behind it is Rust, compiled to
1143WebAssembly for Workers and natively for containers and the CLI. Identity, repos, work, events and the API are all Rust. The one exception
1144is the Worker that starts sandboxes, because Cloudflare's Containers
1145library is TypeScript. Rust services speak a
1146small JSON protocol over service bindings (`POST /rpc/<method>`), with the
1147types in `crates/contracts`.
1148
1149## Identifiers
1150
1151Every id is a [TypeID](https://github.com/jetify-com/typeid): a prefix naming
1152the kind of thing, then a UUIDv7 in lowercase base32, such as
1153`pr_01jb2k7x9hfq0b3zj0f5s2m8ra`.
1154
1155- The prefix makes an id self-describing and stops ids of different kinds
1156 being mixed up.
1157- Ids sort by creation time as plain strings. In SQLite (D1 and Durable
1158 Objects) that keeps inserts at the end of the primary-key index instead of
1159 scattering them, and gives time-ordered paging for free.
1160- The suffix decodes to a standard UUIDv7 for any system that wants one.
1161- Ids are made by the service that creates the record, not by the database,
1162 so they work across services and can be assigned before a write.
1163
1164## Events at scale, and audit
1165
1166The current event log is a single D1 database. That is fine for a
1167prototype and wrong for the target: D1 is one writer and 10 GB. The design
1168for volume splits storage by how the data is read.
1169
1170| Tier | Store | Holds | Read by |
1171| --- | --- | --- | --- |
1172| Hot | A Durable Object per repository, with SQLite | Recent events for that repo | Timelines, live pages over WebSocket |
1173| Complete | Cloudflare Pipelines into R2 as Apache Iceberg | Every event, forever, partitioned by day and workspace | Analytics, standups, "ask", export |
1174| Audit | The same R2 store, under object lock | Who did what, from where, with which credential | Compliance, investigation |
1175
1176- **No single hot database.** Each repository's recent events live with that
1177 repository, so load spreads across as many objects as there are repos.
1178- **The complete record is files, not rows.** Iceberg on R2 has no practical
1179 size limit and is queried with SQL.
1180- **Audit is a property of every event.** The envelope carries the actor
1181 (person, agent, token or system), the credential used, the request id and
1182 the source address. Audit entries for a workspace are hash-chained, so a
1183 removed or altered entry is detectable, and are written under a retention
1184 lock.
1185- **Delivery is at least once.** Consumers are idempotent on the event id.
1186
1187## Accounts and forge basics
1188
1189- Registration with email verification, sign-in, forgot password (Cloudflare
1190 Email Sending), Turnstile on public forms.
1191- GitHub sign-in, SSH keys, access tokens, active sessions.
1192- Profiles, public and private repositories, repository search (D1 full-text).
1193- Rendered README, syntax highlighting, commit history, diffs.
1194- Transferring a repository between workspaces (by id: its git store key
1195 never moves; every service follows `repo.transferred`; old paths redirect
1196 until reused) and deleting an empty, settled workspace (its slug is
1197 tombstoned, never reissued except to the person whose username it is).
1198

1218## Running g1t yourself
1219
1220g1t.sh runs on Cloudflare, and that does not change. The core is MIT and
1221must also run on anyone's own machine with `docker compose up`. A free
1222core people can self-host is what makes paid hosting worth trusting.
1223Self-hosting never makes hosted worse: hosted code paths keep their
1224behaviour, and a self-hosted adapter sits beside the hosted one. The
1225inventory of every Cloudflare dependency, the design and the risks are in
1226[SELF_HOSTING.md](SELF_HOSTING.md).
1227
1228The approach: the Workers stay Workers, and self-hosted they run in
1229workerd, the open-source Workers runtime. D1, KV and Queues are SQLite on a
1230volume, with the same migrations. Cloudflare-only bindings are replaced
1231by stand-ins:
1232
1233- Artifacts becomes bare repositories served by `git http-backend`;
1234- Email Sending becomes SMTP, through Mailpit;
1235- services that are off answer "off" instead of failing.
1236
1237| Phase | Scope | Estimate |
1238| --- | --- | --- |
1239| 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 |
1240| 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 |
1241| 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 |
1242| 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 |
1243
1244## The submission
1245
1246- **g1t is built on g1t.** This repository is hosted on g1t.sh, its features
1247 are opened as issues and built by racing agents, and it deploys from
1248 Artifacts through Workers Builds. The history is the proof.
1249- **The demo follows one story.** A brief becomes a project; twelve issues
1250 fan out to dozens of agents; agents notice each other, hand off, and
1251 resolve a conflict; reviewers triage; the queue lands everything on
1252 `main`; why-blame explains a line; the portfolio shows where it all
1253 stands. Then the same thing at a thousand agents.
1254- **Judges can try it in a minute.** Open registration on g1t.sh, one-click
1255 import of a GitHub repo, one command to connect Claude Code, a seeded demo
1256 workspace, and a single deploy command for running their own copy.
1257- **The formats are open.** The commit trailers, session format and runner
1258 contract are published so other tools can interoperate.

1262What is left is ordered by how much it shows the point above, not by forge
1263parity. Forge basics are done well enough; each item below should make the
1264demo's story stronger.
1265
1266Done from this list: the outcome page (a plan's issues as a live graph with
1267cost and a feed of what happened), coordination you can see (agents' issues
1268and comments stand out in the feed; agents hold g1t's tools through a token
1269scoped to one repository), steering a running agent (messages delivered
1270between steps, and at the end), and recording sessions from anyone's own
1271Claude Code (`curl -fsSL https://g1t.sh/install/claude.sh | sh`). Integrations are
1272in: a workspace's own model provider (Anthropic or any Anthropic-compatible
1273endpoint, reached through a model proxy so no sandbox holds a key; its
1274runs pay only their sandbox time), alerts from Sentry, Datadog and signed webhooks
1275that open one issue per problem and can start an agent, and Jira and Linear
1276tickets that agents read, people import, and that hear back. Racing a
1277set number of agents on one issue is dropped: choosing how many agents to
1278use is not something people should have to do.
1279
12801. ~~**Handoffs and questions between agents** as states on the outcome
1281 page.~~ Done: questions and handoffs show as waiting, read, answered,
1282 taken on or declined; since 2026-10-03 an agent asked while it is not at
1283 work is woken to answer, where before the question waited forever.
12842. **Upkeep agents** (above): dependency updates, secret scanning,
1285 vulnerability alerts, code scanning, the security page. No new
1286 infrastructure.
12873. **Deployments on `g1t.page`** (above): previews per pull request,
1288 production on merge, the reviewer agent checking the preview.
12894. **The large run, building 2 and 3.** About 20–30 issues on g1t itself,
1290 built by agents and landed through the queue, for the video: g1t built
1291 on g1t.
12925. **Polish for judges trying it in a minute:** a seeded demo workspace, the
1293 empty states, and the first-run path from sign-up to an outcome landing.
1294
1295Earlier items still open, after those:
1296
12971. Deleting a branch once its pull request merges; approval rules per
1298 path; risk tiers.
12992. Scopes on OAuth grants and access tokens.
13003. Event storage per the design above: per-repo hot log, Iceberg on R2,
1301 hash-chained audit.
13024. CLI with Claude Code hooks to record sessions automatically.
13035. Reviewing and catching up automatically, by policy; required reviews;
1304 risk tiers.
13056. Compare view, proof bundles; handoff between agents.
13067. Projects, mission control, steering; why-blame, digest, timeline.
13078. Context hub, portfolio; automations and integrations (Sentry first).
13089. SSH; bot protection; own keys, endpoints and runners.
130910. Large run (100+ agents across many issues), hardening, demo.
1310
1311Later: code search, mirroring to GitHub, passkeys, SSH
1312on port 22 without the CLI proxy (needs the Workers inbound TCP private
1313beta).
