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, acceptance checks (commands that must pass), comments, and every pull request made for it. |
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, acceptance
252 checks, 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 acceptance checks pass now compared with when the project started.
263- **Digest.** An agent-written summary per project and per person: what
264 merged, what is blocked on whom, which conflicts were resolved, what it
265 cost.
266- **Timeline.** Every event (push, steer, check, conflict, merge) in order,
267 each linked to the session and the person or agent behind it.
268
269## One session, any surface
270
271A session belongs to g1t, not to the device it started on. The browser, a
272phone and Claude Code are views of the same session.
273
274- **Browser and phone.** The site is a responsive, installable web app with
275 push notifications. Everything a person does (brief, steer, answer,
276 approve, merge) works there.
277- **Claude Code.** Through `mcp.g1t.sh` and the CLI hooks, a local session is
278 a g1t session: its transcript syncs as it runs and it appears in mission
279 control like any other.
280- **Moving a session.** A local session can be sent to the cloud: a hosted
281 agent takes over the fork and the transcript and continues, so the laptop
282 can close. A hosted session can be pulled down: the CLI checks out the fork
283 and resumes it in local Claude Code with its history.
284- **Limit.** A session running only on a laptop stops when the laptop does.
285 It can be steered between turns but not continued until it is moved or the
286 laptop is back.
287
288## For people who do not write code
289
290- **Documents are first-class.** Specs, guides, policies and decisions live
291 in repos as markdown, shown in a Docs view: rendered pages, edited in the
292 browser like a document, with inline comments. "Suggest a change" is an
293 pull request and "publish" is merge, without git vocabulary.
294- **Document issues.** "Write the onboarding guide for the billing API" is
295 an issue. Its acceptance checks are a checklist judged by a reviewer agent
296 instead of commands. Agents draft and revise; people comment and approve.
297- **Templates.** Product brief, RFC, decision record. A filled-in template is
298 a brief the planner can turn into a project.
299- **Explain.** Ask about any repo, project or change in plain language and
300 get an answer with links to the code and sessions behind it.
301- **Living documentation.** g1t generates "how this works" pages from the
302 code and keeps them current. When a merged change contradicts a document,
303 an issue opens to update it.
304- **See it, don't read it.** Every pull request on a deployable repo gets a
305 preview URL (Workers Builds from the pull request's fork), so an approver clicks
306 through the result instead of reading a diff. Changes are also summarised
307 in plain language.
308- **Roles.** Viewer, commenter, planner, approver: a person can plan and
309 approve work without ever cloning a repo.
310
311## The macro view
312
313The hierarchy above a single repo:
314
315| Level | What it is |
316| --- | --- |
317| **Workspace** | A company or team: its people, repos, agents, budget and policies. |
318| **Initiative** | A business outcome with an owner and measurable results, e.g. "move billing to usage-based pricing". Spans any number of repos. |
319| **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. |
320| **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. |
321
322How it feeds up, and what is built:
323
324- **A workspace is the unit everything belongs to.** Repositories, people,
325 access tokens, and later projects, budgets and policies are the
326 workspace's, never a person's. An account owns nothing; its first step
327 after confirming its email is creating a workspace, and the site sends it
328 there from wherever it was going.
329- **One namespace.** Usernames and workspaces share one set of names, as on
330 Docker Hub and npm. A username is reserved for its owner's workspace, so
331 `g1t.sh/<name>` never means two things.
332- **The workspace page is the roll-up.** `g1t.sh/<workspace>` shows its
333 repositories with their open issues and pull requests, and the pull
334 requests in progress across all of them. Projects and initiatives will
335 roll up to the same page. Its own pages live under `/<workspace>/-/`
336 (people, access tokens, settings), which no repository can be named.
337- **Workspace access tokens instead of service accounts.** A workspace has
338 tokens of its own, in the same table and code path as personal ones. One
339 acts as the workspace, with a member's rights in that workspace only,
340 records who made it and when it was last used, and keeps working when
341 that person leaves. CI, integrations and automations use these.
342
343### Portfolio
344
345One page answers "where is the business" across every initiative:
346
347- **Health** per initiative: on track, at risk, or blocked, derived from
348 facts (checks passing, issues stalled, questions waiting on a person),
349 not self-reported.
350- **Progress** as measurable results: acceptance checks passing, issues
351 merged out of planned, and the trend since the start.
352- **Forecast** from actual throughput: at the current rate, when the
353 remaining issues land.
354- **Spend** in tokens and dollars against a budget, per initiative.
355- **Waiting on people**: every decision or approval a person owes, by name.
356- **Roadmap**: initiatives laid out as now, next, later, with optional
357 time-boxed cycles for teams that work in sprints.
358
359### Status without asking
360
361- **Standup.** An agent writes a daily report per initiative and one for the
362 whole workspace: what merged, what changed direction, what is at risk and
363 why, what needs a person. Delivered by email or webhook.
364- **Ask.** A question box over the full event log and all sessions: "what
365 happened on the billing migration since Monday?" answers with links to the
366 sessions and commits behind each claim.
367
368### Long-running agents
369
370Work that runs for days needs supervision that does not depend on someone
371watching.
372
373- **Checkpoints.** A long pull request reports milestones against its issue, so
374 progress is visible before anything merges.
375- **Stall and drift detection.** A pull request with no meaningful progress, or
376 whose changes have wandered away from its issue, is flagged and can be
377 stopped or re-briefed automatically.
378- **Budgets.** Hard limits on spend and time per pull request, project and
379 initiative.
380
381### Context hub
382
383Agents working across repos and days need context that outlives any one
384session and reaches beyond the code. The context hub is one place an agent
385asks, whatever the source.
386
387| Source | What it holds | How it gets there |
388| --- | --- | --- |
389| **Memory** | Decisions, conventions, gotchas, facts about systems | Written by agents and people in g1t |
390| **Code and sessions** | The repos, and the reasoning behind every change | Already in g1t |
391| **Connected sources** | Jira and Linear tickets, Notion and Confluence pages, Google Drive documents, Slack threads, Sentry issues | Connectors, authorised per workspace |
392
393How it behaves:
394
395- **One search.** An agent asks a question and gets ranked results across
396 all sources, each labelled with where it came from, who wrote it, and how
397 fresh it is.
398- **Connected sources stay where they are.** g1t indexes them for search and
399 fetches the current version when an agent opens one. The external system
400 remains the source of truth, and a link placed on an issue ("see
401 JIRA-482", a Notion URL) is pulled into the agent's starting context.
402- **Permissions carry over.** A connector only exposes what the connecting
403 account can see, and a workspace admin chooses which spaces, projects or
404 channels are included.
405- **External content is untrusted.** A ticket or page can contain text meant
406 to manipulate an agent. It is marked as reference material, never treated
407 as instructions.
408- **Documentation is separate.** Context is what agents know; documentation
409 is what people read, and it is generated from context and code.
410
411Memory is the part of the hub that g1t owns and agents write to:
412
413- **Memory is written freely.** Any agent or person adds an entry with one
414 call: a decision, a convention, a gotcha, a fact about a system. No review
415 gate. Each entry records who wrote it, from which session, and when.
416- **It is still a repository.** Each workspace has a memory repo in
417 Artifacts, so every write is a commit: versioned, attributable, and
418 revertible.
419- **It is kept healthy by an agent.** A consolidation agent merges
420 duplicates, retires entries that newer ones contradict, and flags
421 conflicts it cannot settle. People can pin an entry (agents may not change
422 it), correct it, or retract it.
423- **Agents read it.** Every session starts with the context relevant to its
424 issue, found by search, and can query more through MCP.
425- **Updates are events.** A memory write or a change in a connected source
426 is an event, so "when context changes, update the affected docs" is an
427 automation, on by default.
428- **It is scoped inside the workspace.** Some context applies to the whole
429 workspace, some to one initiative, project or repo, so an agent gets what
430 applies to its work.
431- **It never crosses workspaces.** A workspace is the isolation boundary: its
432 context, sessions and private repos are invisible to every other
433 workspace, and an agent's token is bound to one workspace.
434
435## Working in g1t
436
437- **Mission control.** The signed-in home page: every running session, every
438 issue waiting on a decision, and what merged, across all repos.
439- **Outcomes.** Group issues across repos toward one result and track how
440 many are open, racing, or merged. (What [Projects](#projects) means is
441 below.)
442- **Steering.** Send a message to a running pull request, or to all pull requests on an
443 issue at once, without stopping them.
444- **Automations.** Rules that start work without a person (next section).
445
446## Automations and integrations
447
448> **2026-10-03:** g1t's own `.g1t/automations` format was built and then set
449> aside at the user's request ("let's just copy GitHub Actions on that for the
450> time being"). Automation on g1t is GitHub Actions workflows in
451> `.g1t/workflows/`; the format below is kept for later.
452
453An automation is **when** an event happens, **if** conditions hold, **do**
454something. They are defined as files in the repo (`.g1t/automations/`), the
455way GitHub Actions workflows are, and can also be built in the UI.
456
457### Events that can trigger one
458
459| Source | Examples |
460| --- | --- |
461| Git | push, merge, check failed, `main` moved |
462| g1t | issue opened, pull request stalled, context updated, handoff declined, budget reached |
463| Time | cron schedule |
464| Integrations | Sentry issue, PagerDuty incident, Linear or Jira ticket, Slack message or mention, GitHub issue, Stripe event |
465| Anything else | a signed generic webhook, or an email to a per-repo address |
466
467**Actions**: open an issue (optionally assigning N agents to it), message
468a running pull request, update documentation, notify, call a
469webhook, write back to the source system.
470
471**Example: Sentry.** A new production error arrives. The automation opens an
472issue labelled `bug`, with the stack trace, release and frequency in its
473description. Why-blame
474finds the session that wrote the failing line, so the fixing agent starts
475with the original reasoning. When the fix merges, g1t comments on the Sentry
476issue and resolves it.
477
478### Rules every automation obeys
479
480- **Deduplication.** The same Sentry issue firing 500 times maps to one
481 issue.
482- **Limits.** Concurrency and budget caps per automation.
483- **Loop protection.** Work started by an automation cannot retrigger the
484 same automation without a person in between.
485- **External input is untrusted.** A webhook payload can contain text written
486 by an attacker. Agents started by external events run with reduced
487 permissions and cannot merge without the repo's approval rule passing.
488
489**Checks** are the other half of what GitHub Actions does: build and test
490commands declared in `.g1t/checks.yaml`, run in sandboxes on every pull request
491and on every combined state in the landing queue.
492
493Agents can also reach integrations directly: an agent definition lists MCP
494servers (Sentry, Linear and so on) it may use while working.
495
496## A repository that maintains itself
497
498> **2026-10-04:** the user asked for Dependabot, GitHub Advanced Security and
499> Vercel-style deployments, "so you're not having to maintain shit and you're
500> just pushing up agents that are delivering work consistently".
501
502GitHub reports problems and leaves the fix to you. In g1t, an agent opens an
503issue for each problem, writes the fix, runs its checks, links a preview and
504lands it through the queue. People only decide.
505
506### Upkeep agents
507
508- **Dependency updates.** A scheduled scan reads the lockfiles (npm, Cargo,
509 Go, pip), finds outdated and vulnerable packages and opens one issue per
510 update or group, assigned to g1t-agent. The agent upgrades the package,
511 fixes what the upgrade broke and lands it through the queue. A repository
512 sets how often it scans, which packages it groups and what lands without
513 review (`.g1t/upkeep.yml`, shaped like `dependabot.yml`).
514- **Secret scanning.** Pushes are scanned for known token formats. A push
515 that adds a secret is refused with the file and line; one already in
516 history opens an issue to rotate it and remove it.
517- **Vulnerability alerts.** Dependencies are matched against the OSV
518 database. Every alert links to the issue and pull request fixing it.
519- **Code scanning.** A reviewer agent reads each pull request's diff for
520 security problems and leaves findings as review comments with a
521 suggested fix. Findings on `main` open issues.
522- **A security page per repository** lists alerts, secrets and findings,
523 with the agent work on each, like GitHub's Security tab.
524
525All of these are event sources for the existing issue → agent → checks →
526queue pipeline; they need no new kind of work.
527
528### Deployments
529
530- **A preview for every pull request**, at
531 `<pr>--<repo>--<owner>.g1t.page`, linked on the pull request and updated
532 on each push. `main` deploys to `<repo>--<owner>.g1t.page`, and a
533 repository can add its own domain.
534- **On g1t.page, not g1t.sh,** so customer code never shares cookies or an
535 origin with the site people sign in to.
536- **Built on Workers for Platforms.** Each deployment is a user Worker in a
537 dispatch namespace; one dispatch Worker on `*.g1t.page` routes to it. The
538 build runs in the same runners as Actions. Static sites and Workers apps
539 first; container apps and databases later.
540- **Agents use the preview.** The reviewer agent opens the preview in a
541 browser, takes screenshots of what changed and attaches them to its
542 review, so an approver sees the result without reading the diff.
543- **Environments.** Preview, production and their secrets; deploy history
544 and one-click rollback.
545- **Scale to zero.** An idle branch costs neither g1t nor the customer
546 anything: a Worker runs, and is billed, only while it answers a request.
547 A preview is deleted when its pull request closes or merges, and after
548 a set number of idle days. Container apps, later, sleep when idle.
549- **Billed to the customer, never free.** The user (2026-10-04): "we
550 should not be giving any of this available for free". Every deployment
551 is metered per workspace (requests, CPU time, deployed apps, stored
552 data), priced at Cloudflare's cost + 20% like agent usage, and drawn
553 from prepaid credit. `FREE_WHILE_BUILDING` and the free model allowance
554 do not cover deployments: a workspace without credit cannot deploy, and
555 turning deployments on says so first.
556- **Turning them on is a paid plan, the way Cloudflare's is.** "Including
557 things like them even enabling the feature should have that pay like
558 Cloudflare does." Enabling deployments for a workspace starts a monthly
559 fee that includes an allowance of requests, CPU time and deployed apps;
560 usage past it is billed per unit, as Workers for Platforms bills g1t.
561 The fee and allowance are the user's to set.
562- **Recommended, off in one click.** Because enabling costs money, it is
563 never switched on without the workspace agreeing: new repositories
564 recommend it prominently. A repository can turn it off, keep only production, or
565 deploy somewhere else from its own workflows. Apps built for Cloudflare
566 (Workers, static assets, D1, KV, R2) deploy without configuration.
567
568Later, toward GitLab's DevOps breadth: environment protection rules,
569package and container registries, releases, container hosting.
570
571## Projects
572
573> **2026-10-04:** the user: "an extra dimension of Projects so it's not
574> just repositories … where a lot of things can live", "very Vercel
575> like", with dependencies across projects "the Platform Engineering /
576> Port route", and "the repository is *part* of a project: you could be
577> mirroring it from GitHub/GitLab/Bitbucket, or you could let us host it
578> for you", with room for Mercurial or anything else later.
579
580**A project is the thing you are building and running; a repository is
581where some of its code lives.** Everything that is about running software
582(deployments, environments, domains, secrets, dependencies, owners,
583health, upkeep) belongs to the project. What is about the code itself
584(branches, pull requests, review, merge rules) stays with the repository.
585That split is what lets the code live anywhere.
586
587### The model
588
589| | What it is | Like |
590| --- | --- | --- |
591| **Workspace** | The company or team. Members, billing, plans, shared secrets. | Vercel team, GitLab group, GitHub org |
592| **Group** | An optional named set of projects, one level: "Payments", "Mobile". For browsing, ownership and shared settings. | GitLab subgroup, Backstage system, Port domain |
593| **Project** | One deployable thing: a site, an API, a worker, a library. Has exactly one **source**. | Vercel project, Port service, Backstage component |
594| **Source** | Where its code is: a repository and a **root directory** in it. | Vercel's connected repo + root directory |
595| **Dependency** | Project A uses project B: calls its API, consumes its package, reads its queue. | Port relations, Backstage `dependsOn` |
596
597- **One project, one source; one repository, any number of projects.** A
598 project builds from exactly one place, which keeps it as simple as
599 Vercel's. A monorepo is several projects on one repository, each with
600 its own root directory (`apps/web`, `services/api`), and a push builds
601 only the projects whose root it touched. The common case stays 1:1, and
602 every existing repository gets a project of its own name when this
603 ships, so nobody has to set anything up.
604- **Groups are for people; dependencies are for software.** Groups decide
605 where a project shows up and who owns it. Dependencies decide what
606 happens when one changes. Neither replaces the other, and a dependency
607 can cross groups.
608
609### Sources: where the code lives
610
611A source is an adapter behind one interface (`SourcePort`: clone URL,
612branches, commits, pushes as events, pull requests if it has them):
613
614| Source | Code lives | g1t gets pushes by | Pull requests |
615| --- | --- | --- | --- |
616| **Hosted on g1t** (today) | Artifacts | its own events | g1t's, with agents, the queue, review |
617| **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 |
618| **Connected, not copied** | The provider only | webhook | The provider's |
619| **Later:** Mercurial, Perforce, a tarball upload | Behind the same port | per adapter | per adapter |
620
621A mirrored or connected project still gets everything that is the
622project's: previews on its pull requests (a status and a comment on
623GitHub's), production on its default branch, secrets, dependencies,
624upkeep agents. That is the on-ramp: a team keeps GitHub and gets g1t's
625deployments and agents first, and moves the code later or never.
626Bring-your-own-git is also why the project, not the repository, holds the
627URL `g1t.sh/<workspace>/<project>`.
628
629### What lives on a project
630
631| | Today it is on | Moves to the project |
632| --- | --- | --- |
633| Deployments: production, previews, build settings, root directory, framework | The repository | Yes |
634| Environments: production, preview, and custom ones (`staging`) with protection rules (required approvers, branch limits) | Nowhere yet | New, on the project |
635| Domains: `<project>--<workspace>.g1t.page`, and custom domains | The repository's name | Yes |
636| 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). |
637| Dependencies | Nowhere | New |
638| Owners, on-call, links (docs, dashboards, runbooks) | Nowhere | New: the catalog's metadata |
639| Health: scorecards (has an owner, CI passes, dependencies current, no open security alerts, deploys within N days) | Nowhere | New |
640| Upkeep agents: dependency updates, security alerts | The plan | Scoped per project |
641| Logs and analytics of the running app | Nowhere | New: requests, errors and CPU per environment, from Workers analytics |
642| Branches, pull requests, review, merge rules, the queue, webhooks | The repository | Stay |
643
644### Dependencies: why this gets powerful
645
646Declared in the UI, or in the source as `.g1t/project.yml` (which wins
647when present, as `catalog-info.yaml` does in Backstage):
648
649```yaml
650name: web
651root: apps/web
652dependsOn:
653 - project: api # calls its HTTP API
654 as: API_URL # its URL, per environment, as a variable
655 - project: ui-kit # consumes its package
656```
657
658What g1t does with them:
659
6601. **Reference variables.** `API_URL` above resolves to `api`'s production
661 URL in production and to the matching preview in a preview, the way
662 Railway's `${{ api.URL }}` references work. No hard-coded URLs.
6632. **Preview stacks.** A pull request on `api` gets its own preview, and
664 **Preview with dependents** builds `web`'s preview pointed at it, so a
665 reviewer clicks through the whole change across projects. A change that
666 spans repositories (one issue, one fork per repository) gets one stack.
6673. **Release order.** Production deploys go out in dependency order; a
668 change set across projects lands through the queue together or not at
669 all.
6704. **Impact on every pull request.** "Changes `api`; `web` and `mobile`
671 depend on it." Agents get the graph in their context: an agent
672 changing an API opens follow-up issues on the projects that call it,
673 and reviewers see what else could break.
6745. **Upkeep across the graph.** A vulnerable package in `ui-kit` opens
675 issues, assigned to agents, on every project that consumes it.
6766. **Scorecards turn into work.** A project failing a scorecard check
677 ("no owner", "dependencies 90 days old") gets an issue an agent can fix.
678 That is the Port idea with the work done for you.
6797. **The map.** A workspace's projects as a graph, coloured by health and
680 by what is deploying now.
681
682### Pages
683
684- `g1t.sh/<workspace>`: projects first (grouped, with health and
685 production status), then repositories.
686- `g1t.sh/<workspace>/<project>`: overview (production, latest previews,
687 health, owners, dependencies both ways), **Deployments**,
688 **Environments**, **Secrets and variables**, **Logs**, **Settings**
689 (source, root directory, build, domains, groups, owners).
690- A hosted repository keeps its code pages; from a project they are its
691 **Code** tab. A repository page lists the projects built from it.
692
693### Services
694
695- `services/projects` (new): projects, groups, sources, dependencies,
696 owners, scorecards. Events `project.created`, `project.updated`,
697 `dependency.changed`.
698- `services/deployments`: keyed by project instead of repository.
699- Secrets and variables: the scope becomes workspace → project.
700- Sources: the hosted adapter wraps `services/repos`; a mirror adapter
701 per provider in `services/integrations`, which already holds those
702 connections.
703
704### Build order
705
7061. **Projects as the home of deployments and secrets**, 1:1 with every
707 existing repository: the service, the pages, deployments and secrets
708 moved to the project, `<project>--<workspace>.g1t.page`.
7092. **Dependencies:** declared in the UI and `.g1t/project.yml`, reference
710 variables, impact on pull requests and in agents' context, the map.
7113. **Preview stacks** and cross-project change sets.
7124. **Monorepos:** several projects on one repository, each with a root
713 directory, building only what a push touched.
7145. **Mirrored sources:** GitHub first, then GitLab and Bitbucket.
7156. **Groups, owners, scorecards** feeding the upkeep agents.
7167. **Environments** with protection rules; custom domains; logs.
717
718**Step 1 shipped 2026-10-04:** `services/projects`; every repository a
719project of its own name; the site projects-first (workspace page of
720project cards, the project overview at `g1t.sh/<workspace>/<project>`, code
721under `/code`, the sidebar and the New project flow); deployments keyed by
722project and branch at `<project>-<workspace>.g1t.page` and
723`<project>-git-<branch>-<workspace>.g1t.page`; secrets and variables owned
724by the project.
725
726**Step 5, GitHub, built 2026-10-05:** one GitHub App (`g1t-sh`) for both
727sign-in and repository access. Sign-in is its user authorization with PKCE
728(identity, `src/github.rs`): accounts known by GitHub's numeric id, a
729matching verified email never linked without signing in to the account,
730new accounts behind the invite check. Repositories come through its
731installations (integrations, `src/github.rs`), copied with every branch and
732tag by the repos service (`src/mirror.rs`) as **import**, **mirror** (g1t
733follows GitHub on its push webhook) or **move to g1t** (GitHub follows g1t
734on `git.push`). A mirror is a hosted repository that keeps a full copy, so
735its project stays `hosted` and deploys like any other; the tie lives in
736integrations' `github_repos`. Not yet: previews and statuses on GitHub's own
737pull requests, comments and pull requests copied, GitLab and Bitbucket.
738
739### People and search
740
741> **2026-10-04:** "pull up user profiles, using a /u/username prefix kinda
742> like DockerHub … search for users if you search that explicitly, how
743> GitHub has the aside for searching against filters … a significantly
744> stronger implementation."
745
746- **Profiles at `g1t.sh/u/<username>`**, apart from workspaces at
747 `g1t.sh/<workspace>`: who they are, their workspaces, recent work,
748 agents' sessions they steered.
749- **Search with a filter sidebar:** Projects, Code, Issues, Pull requests,
750 Users, Workspaces, each with its count; filters by workspace, language,
751 state, author, agent, label, date; qualifiers in the query
752 (`user:`, `is:open`, `agent:g1t-agent`) as on GitHub. Typing `u/name`
753 searches people directly, as Docker Hub does.
754
7551 and 2 serve the competition directly (multi-agent coordination across
756projects is 25% of the score); 3 is the demo's best moment if time allows.
757
758## Billing model
759
760> **2026-10-04:** "Some things just require you to have a card on file …
761> some things will be something you give us an initial amount of money
762> per month just to activate, tons of things additionally will be usage
763> based, some things will just be usage based only … at minimum a
764> breakeven with Cloudflare costs, or in some cases a value add." Stripe
765> moves to Flagon, Inc. (g1t.sh is its product). Proposed below; the
766> prices are the user's to confirm.
767
768### Four kinds of charge
769
770Every feature is exactly one of these, and the Billing page says which:
771
772| Kind | What the workspace does | Example |
773| --- | --- | --- |
774| **Free** | Nothing | Hosting code, issues, pull requests, review, the merge queue, bringing your own agent over MCP |
775| **Card on file** | Adds a card; pays only for what it uses | Previews, g1t's agents, workflow minutes |
776| **Activation** | Turns a feature on for a monthly fee that includes an allowance; usage past it is metered | Production deployments, Security and quality |
777| **Usage only** | Nothing up front; every unit is metered | Model tokens, build minutes, storage past the free amount |
778
779A card is needed before anything that can cost money starts. Nothing is
780ever switched on without the workspace choosing it.
781
782### Postpaid, with spend limits
783
784- **One Stripe customer and one subscription per workspace**, on Flagon,
785 Inc.'s account. Activations are licensed line items; every usage
786 dimension is a metered price backed by a Stripe Meter. Stripe invoices
787 monthly in arrears and charges the card on file; failed payments go
788 through Stripe's retries and emails, and g1t hears of them by webhook.
789- **Spend limits instead of prepaid credit.** A workspace sets a monthly
790 limit overall and per feature (Vercel's spend management). g1t counts
791 usage as it happens and stops starting new paid work at the limit,
792 with a warning at 50%, 80% and 100%. Prepaid top-ups go away; promotions
793 (the free model allowance) become Stripe credit on the customer.
794- **Usage reaches Stripe from billing alone.** Every service reports
795 usage to the billing service as it happens (it already records agent
796 runs and builds); billing batches them into Stripe meter events every
797 few minutes, idempotently by g1t's own ids, and keeps the ledger g1t's
798 pages show. Nothing else talks to Stripe.
799
800### Scope: workspace, then projects
801
802- A feature is turned on for the **workspace** (by an owner, with the
803 activation if it has one), then allowed for **all projects** or
804 **selected projects**.
805- Every **project** can opt out on its own page. A project with nothing
806 to deploy (no Workers config, no build script, no `index.html`) is
807 detected, says so on its Deployments page, and never builds or costs
808 anything.
809- Agents and workflows are allowed per project the same way, so a
810 workspace can keep spend to the projects that matter.
811
812### Prices: what it costs us, passed through
813
814> **2026-10-04, decided:** postpaid with spend limits, as Vercel and
815> Cloudflare do; no per-seat price, ever ("fuck per-seat pricing").
816> "If they're barely using them great, but if they're using the shit out
817> of them that will cost me a ton, so that cost needs to move onto them."
818
819**Every Cloudflare cost a workspace causes is metered to it.** Light use
820fits in a small free allowance; past it, each unit is charged at
821Cloudflare's price times a margin of at least 1.5, which pays for Stripe
822(about 3%), shared overhead (the site, the API, D1) and g1t itself.
823
824Cloudflare's prices (October 2026), and the cost per unit g1t meters:
825
826| What g1t meters | Cloudflare's price | Cost to g1t per unit |
827| --- | --- | --- |
828| **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) |
829| **App request** (deployments) | Workers for Platforms: $0.30 / million past 20M | $0.30 / million |
830| **App CPU** | $0.02 / million CPU-ms past 60M | $0.02 / million ms |
831| **App** (a deployed script) | $0.02 / script-month past 1,000 | $0.02 / app-month |
832| **Storage** (repositories, artifacts, caches) | Artifacts $0.50 / GB-month (billing starts 2026-10-14); KV $0.50 / GB-month | $0.50 / GB-month |
833| **Git operation** (clone, fetch, push) | Artifacts $0.15 / 1,000 past 10,000 | $0.15 / 1,000 |
834| **Model tokens** | The provider's price | As charged |
835| Container egress, emails, the site's own requests | Small and shared | In the margin |
836
837> **2026-10-06, decided:** no per-feature quotas on the plan. "A paying
838> user should be able to push past the Git operations number, they're
839> just paying usage on it." One plan, $20 a month per workspace with $10
840> of usage included; every meter is charged from the first unit at cost +
841> 20% (builds, app requests and CPU, custom domains), drawn from the $10
842> first, then up to the spend limit, which is the only thing that stops a
843> paying workspace (with abuse protection). Projects, previews and apps
844> are not metered (Workers for Platforms' script pool makes them ~free).
845> The forge's free amounts are the same for everyone: 1 GB private storage
846> and 50,000 git operations a month; past them the plan pays and a free
847> workspace is held (pushes stop, git slowed). The table below is the
848> earlier proposal; billing's price book and g1t.sh/pricing are current.
849
850What a workspace pays:
851
852| Meter | Free each month | Then | Margin | For comparison |
853| --- | --- | --- | --- | --- |
854| 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 |
855| App requests | 1 million with Deployments | $0.50 / million | 1.7× | Vercel $0.60 / million invocations |
856| App CPU | 3 million ms with Deployments | $0.04 / million ms | 2× | Vercel active CPU about $0.036 / million ms |
857| Apps | 10 with Deployments | $0.05 / app-month | 2.5× | |
858| Storage | 1 GB | $1.00 / GB-month | 2× | GitHub LFS $0.07 / GB, but repositories are free there |
859| Git operations | 10,000 | $0.30 / 1,000 | 2× | |
860| g1t's models | | Cost + 20% | 1.2× | The provider's own price |
861| Your own model provider | | Only its sandbox minutes (the $0.10 run fee was dropped 2026-10-05) | | |
862| **Deployments** activation | | $5 / month, with the allowances above | covers Workers for Platforms' $25 / month across workspaces | Vercel Pro $20 per seat |
863| **Security and quality** activation (later) | | $10 / month; fixes as agent usage | | GitHub Advanced Security $49 per committer |
864
865A workspace that uses g1t lightly (a few agent runs, a small site)
866pays nothing or its activation; a workspace running agents all day pays
867for the sandboxes and models those agents use, with g1t's margin on
868each. Nothing in a workspace's bill is subsidised by another's.
869
870### Build order
871
8721. Stripe customer per workspace and card on file (Checkout in setup
873 mode), webhooks (invoice paid and failed, subscription changes,
874 payment method changes), the Billing page rebuilt around the four
875 kinds.
8762. One subscription per workspace with activations as items; Deployments
877 moves onto it.
8783. Meters for each usage dimension above, fed from billing's ledger:
879 every sandbox reports how long it ran when it stops (agents, checks,
880 the queue, workflow jobs and deploy builds alike); deployments report
881 requests, CPU and apps; repos report storage and git operations. Spend
882 limits and their warnings; prepaid credit retired.
8834. Per-workspace allow-lists of projects for each feature, and per-project
884 opt-out; "nothing to deploy" detection.
8855. Turn off FREE_WHILE_BUILDING when the user says so. **Done 2026-10-05.**
886
887Shipped by 2026-10-05: sandbox seconds for every sandbox; the price book
888and its keeper (runs settled to AI Gateway's price every 15 minutes;
889Container and Workers costs checked against Cloudflare's billable usage
890and container analytics daily, with a public change log on
891g1t.sh/pricing); usage limits by trust with automatic payment near the
892limit; app traffic counted toward limits as it happens; billing accounts,
893terms and enterprises; free mode off, syntaqx comped.
894
895Still to build, in order: Stripe card-on-file without a payment (setup
896mode) and webhooks; month-end invoices for postpaid usage (and one
897invoice per enterprise); the subscription with activations as items;
898storage and git-operation meters; limit warnings by email at 50/80/100%;
899self-serve enterprise management for enterprise owners.
900
901### Accounts, terms and enterprises
902
903Every workspace is paid for by a billing account: its own (`ws_<slug>`)
904or an enterprise's (`ent_…`), which pays for several workspaces with one
905limit, one set of terms and, once invoices exist, one bill, as GitHub
906Enterprise does. Terms are standard, comped (nothing charged, usage still
907recorded at cost, paid features on) or custom (a discount, its own
908ceiling, an end date). g1t staff manage them in **sudo.g1t.sh**, a
909separate Worker behind Cloudflare Access that also verifies the Access
910token itself and allows only listed staff emails; every change is kept
911with who made it and why.
912
913### Limits: stop non-payers, never payers
914
915The limit is on usage not yet paid for, counted at cost to g1t or charge,
916whichever is more: $3 before any live payment, then twice what has been
917paid ($25 to $1,000), or what staff set. A workspace with a card on file
918is charged automatically near its limit, which both pays what it owes and
919raises the limit, so paying users are never stopped. A declined card
920stops work until paid. The owner's own spend limit always means stop.
921Test-mode payments never lower exposure or raise trust.
922
923## Agents and models
924
925### Defining an agent
926
927An agent is a file (`.g1t/agents/<name>.md`, or in the workspace library):
928instructions, the harness and model to run, the tools and MCP servers it may
929use, its sandbox image, permissions and budget. Agents take roles: planner,
930implementer, reviewer, conflict resolver, documenter, memory consolidator.
931Each role has a default that a repo can replace.
932
933### Where it runs, and on whose model
934
935| Option | How it works | Fits |
936| --- | --- | --- |
937| Hosted, g1t's model | g1t runs the sandbox and bills usage | Getting started; no keys to manage |
938| Hosted, your API key | Same sandbox, your Anthropic, OpenAI or Google key | Teams with existing contracts |
939| Hosted, your endpoint | Any OpenAI-compatible URL: Bedrock, Vertex, Azure, a self-hosted model | Private or fine-tuned models |
940| Your runner | A g1t runner daemon on your own machines picks up pull requests | Code or models that may not leave your network |
941| Your own session | Local Claude Code, Cursor or any MCP client joins through `mcp.g1t.sh` | Individuals; subscription plans |
942
943Decisions behind this:
944
945- **g1t does not build its own agent loop.** It runs existing harnesses
946 (Claude Code first, through its headless mode) behind a small runner
947 contract: a container image, an entry command, and session events reported
948 through the CLI. Other harnesses plug in by meeting the contract.
949- **All hosted model traffic goes through Cloudflare AI Gateway.** That gives
950 one place for spend tracking, budgets, rate limits, fallback and logs,
951 whichever provider or endpoint is behind it.
952- **Nobody picks a model.** A person assigns work to `g1t-agent`, as they
953 would assign an issue to Copilot, and g1t routes it. Today the kind of
954 work decides (implementing, reviewing, catching up), from one setting on
955 the runner, and each request is tagged at the gateway with that kind, the
956 repository and the pull request. The session records which model ran.
957 The gateway's own dynamic routes cannot make the choice yet: they work
958 only on its OpenAI-compatible endpoint, and the harness speaks
959 Anthropic's.
960- **Subscriptions stay local.** A Claude subscription cannot be used by a
961 hosted sandbox; it needs an API key. People on subscriptions use their own
962 Claude Code session, which is a full participant.
963- **The workspace pays.** A workspace buys credit by card and each agent
964 run deducts what the model cost plus a margin. The billing service asks
965 nothing of the others: the runner asks it before starting a sandbox and
966 is refused when there is no credit, and the sandbox reports what its run
967 cost with a token only it holds. Where no card processor is configured
968 nothing is charged and agents stay limited to listed accounts.
969- **Keys are secrets.** Stored in Cloudflare Secrets Store, injected into the
970 sandbox for one pull request, never shown again.
971
972### Seeing a pull request through
973
974Assigning an issue is the only thing a person does until there is something
975to merge. A pull request made by a g1t agent goes through checks, a review
976by another agent, revision when either finds something, and catching up
977when `main` moves, without anyone pressing a button. It ends as ready to
978merge, or as "needs you" with the reason: the checks still fail after two
979revisions, a review could not be written, or a conflict could not be
980resolved.
981
982The work service decides the next step from the pull request's state and
983claims it in one statement, so a step is taken once. The runner asks on
984every event that could change the answer (ready, pushed, checks finished,
985review finished, `main` moved), and on a five-minute sweep for anything
986missed, and carries the step out in a sandbox.
987
988A pull request does not have to be up to date with `main` to merge,
989unless the repository's settings require it, as on GitHub. Merging one that
990is behind brings it up to date first (a clean merge needs no model; an
991agent resolves a conflict) and lands it when that push arrives. With the
992requirement on, catching up is a step of its own and the checks run again
993on the result.
994
995Each repository sets its own rules, on one settings page: whether its
996default branch takes pushes at all, how many approvals a merge needs and
997whether an agent's counts, whether failed checks can be overridden, whether
998a second agent reviews, and how often an agent is sent back before a person
999is asked. A g1t agent's pull request follows the same rules as anyone's.
1000Pushes to a protected branch are refused in the git front end, with the
1001reason shown by git beside the branch.
1002
1003Merging is a person's decision unless the repository says otherwise. With
1004"merge automatically when ready" turned on in its settings, a ready pull
1005request lands by itself, attributed to `g1t`. That is the whole path from
1006an assigned issue to a commit on `main` with nobody in between. Required
1007human approval per path, and risk tiers, are still to come.
1008
1009### Choosing the right agent automatically
1010
1011Because several agents can work on the same issue, every issue with more
1012than one pull request is an evaluation on real work. g1t records, per repo and per kind of issue, each
1013agent's win rate, cost and time. That produces a leaderboard, and a routing
1014policy: send each new issue to the agent that wins that kind most often,
1015start with the cheapest that is good enough, and escalate to a stronger one
1016when checks fail.
1017
1018## Talking: the inbox and channels
1019
1020Not a discussions forum. People and agents need one place to talk in real
1021time, and an app that feels like one on desktop and phone.
1022
1023**The inbox comes first.** Everything that needs a person or that they
1024follow, from people and agents: review requests, agent questions and
1025handoffs, failures, mentions, deploys. Read and unread, saved, done,
1026snoozed; ranked so what an agent is blocked on comes first; email digests
1027and push. It is the delivery layer chat needs too (who is told what, read
1028state, push), so building it first makes channels cheap.
1029
1030**Channels** (working name): workspace channels, direct messages and
1031threads, live.
1032
1033- Each channel is a Durable Object holding its WebSocket connections with
1034 hibernation, so idle channels cost nothing; history in D1, files in R2.
1035- Agents are members. `@g1t-agent` in a channel starts work, answers, or
1036 posts a summary; agents post their questions and handoffs where people
1037 already are. A thread becomes an issue or an outcome in one action, and
1038 the agent's progress streams into that thread.
1039- Tied to the work: issues, pull requests, runs and deploys each have a
1040 thread; links unfurl into live cards (checks, agent step, preview).
1041 What a channel settles can become workspace memory, with its source.
1042- Apps: an installable PWA first (desktop and mobile, offline shell, Web
1043 Push), then native shells on the same API: Tauri for desktop (tray,
1044 deep links), React Native for iOS and Android (background
1045 notifications).
1046
1047GitHub-style Discussions are not planned: channels and threads on the
1048work replace them.
1049
1050## What GitHub ships today, and where g1t differs
1051
1052GitHub's Agent HQ and Copilot app give each agent session its own git
1053worktree and branch, list sessions in a mission-control view grouped by
1054project, and let a task be assigned to several agents so their output can be
1055compared. Underneath, the unit of work is still a branch and a pull request.
1056
1057| | GitHub | g1t |
1058| --- | --- | --- |
1059| 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 |
1060| Agent context | Lives in the app's session view | Stored with the repository and linked from each commit (why-blame) |
1061| 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 |
1062| Collisions between agents | Found as merge conflicts at the end | Flagged during the work (overlap radar) |
1063| Landing changes | One pull request at a time | A merge queue that lands the chosen one and closes the rest as superseded |
1064| Which agents | Those offered through a Copilot subscription | Any MCP client, plus hosted agents |
1065
1066## How agents connect
1067
10681. **Bring your own agent.** A remote MCP server at `mcp.g1t.sh` lets Claude
1069 Code (or any MCP client) list issues, claim one, get a clone URL and
1070 token, report progress and submit. Adding it is one command; sign-in is a
1071 browser OAuth flow with no token to paste. The `g1t` CLI installs Claude
1072 Code hooks that upload the session transcript as the agent works.
10732. **g1t agents.** Assign an issue to g1t's own agent, or many issues at
1074 once, each to an agent of its own. g1t starts a sandbox for each
1075 (Cloudflare Containers), running a coding agent headless against its
1076 own pull request and fork.
10773. **API and CLI.** Everything above is available at `api.g1t.sh` and
1078 through `g1t`.
1079
1080## Public surfaces
1081
1082| Host | What it serves |
1083| --- | --- |
1084| `g1t.sh` | The site, git over HTTPS, git over SSH |
1085| `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 |
1086| `mcp.g1t.sh` | Remote MCP server over streamable HTTP |
1087
1088g1t is its own OAuth 2.1 authorization server: authorization code with PKCE,
1089dynamic client registration that stores nothing (a client id encodes its
1090own registration, so the open endpoint cannot be used to fill a database),
1091discovery metadata and rotating refresh tokens. Still to come: scopes
1092per resource (`repo:read`, `repo:write`, `issue:write`, `pull:write`).
1093MCP clients, the CLI (device flow) and third-party apps all use it. Access
1094tokens and SSH keys remain for git itself.
1095
1096## Architecture
1097
1098| Component | Language | Runs on | Responsibility |
1099| --- | --- | --- | --- |
1100| `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. |
1101| `services/identity` | Rust | Worker + D1 | Accounts, workspaces and memberships, sessions, SSH keys, access tokens, device sign-in, OAuth codes and grants |
1102| `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. |
1103| `services/work` | Rust | Worker + D1 | Issues, pull requests, comments, sessions; later a Durable Object per repo for the landing queue and live state |
1104| `services/billing` | Rust | Worker + D1 + Stripe | Each workspace's agent credit: payments, the ledger of every run, and the gate on starting one |
1105| `services/events` | Rust | Worker + Queues + D1 | The event bus: durable log, and one queue per subscribing service |
1106| `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 |
1107| `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 |
1108| `apps/web` | TypeScript | Worker | Server-rendered site. Holds no data; calls services over RPC. |
1109| `apps/docs` | TypeScript | Worker (static) | Documentation and the API explorer |
1110| `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 |
1111| `crates/sshd` | Rust | Container | Git over SSH, bridged to Artifacts |
1112| `crates/merged` | Rust | Container | Trial merges, conflict matrix, landing merges (needs real git; the Artifacts binding is read-only) |
1113| `crates/core` | Rust | native and WASM | pkt-line, packfile and diff code shared by the above and by the Worker |
1114| `crates/g1t` | Rust | user's machine | CLI: auth, SSH proxy, Claude Code hooks, issues and pull requests |
1115
1116Storage: Artifacts for repositories (one fork per pull request), D1 for accounts
1117and metadata, R2 for session transcripts and logs, Durable Object SQLite for
1118per-repo coordination state.
1119
1120How the services fit together:
1121
1122- **Each service is its own Worker with its own database.** It deploys,
1123 scales and fails on its own. Callers reach it through a typed RPC binding
1124 to the interface in `packages/contracts`.
1125- **Expected failures are values.** Every call returns a `Result`, so "not
1126 found" or "forbidden" crosses a service boundary as data.
1127- **Side effects travel as events.** A service publishes what happened
1128 (`git.push`, `issue.opened`, `pull.merged`, …) to the bus and does not
1129 call other services to react. Each subscriber consumes from its own queue.
1130 Timelines, webhooks and automations read the same stream, which is what
1131 lets something like GitHub Actions be built on top.
1132- **Every read takes the viewer.** Authorization is decided inside the
1133 service that owns the data, not by its callers.
1134
1135The Workers runtime scales request handling on its own, so the edge layer
1136stays in TypeScript. Rust is used where there is real computation or a real
1137protocol to implement.
1138
1139## Languages
1140
1141The site is TypeScript. Everything behind it is Rust, compiled to
1142WebAssembly for Workers and natively for containers and the CLI. Identity, repos, work, events and the API are all Rust. The one exception
1143is the Worker that starts sandboxes, because Cloudflare's Containers
1144library is TypeScript. Rust services speak a
1145small JSON protocol over service bindings (`POST /rpc/<method>`), with the
1146types in `crates/contracts`.
1147
1148## Identifiers
1149
1150Every id is a [TypeID](https://github.com/jetify-com/typeid): a prefix naming
1151the kind of thing, then a UUIDv7 in lowercase base32, such as
1152`pr_01jb2k7x9hfq0b3zj0f5s2m8ra`.
1153
1154- The prefix makes an id self-describing and stops ids of different kinds
1155 being mixed up.
1156- Ids sort by creation time as plain strings. In SQLite (D1 and Durable
1157 Objects) that keeps inserts at the end of the primary-key index instead of
1158 scattering them, and gives time-ordered paging for free.
1159- The suffix decodes to a standard UUIDv7 for any system that wants one.
1160- Ids are made by the service that creates the record, not by the database,
1161 so they work across services and can be assigned before a write.
1162
1163## Events at scale, and audit
1164
1165The current event log is a single D1 database. That is fine for a
1166prototype and wrong for the target: D1 is one writer and 10 GB. The design
1167for volume splits storage by how the data is read.
1168
1169| Tier | Store | Holds | Read by |
1170| --- | --- | --- | --- |
1171| Hot | A Durable Object per repository, with SQLite | Recent events for that repo | Timelines, live pages over WebSocket |
1172| Complete | Cloudflare Pipelines into R2 as Apache Iceberg | Every event, forever, partitioned by day and workspace | Analytics, standups, "ask", export |
1173| Audit | The same R2 store, under object lock | Who did what, from where, with which credential | Compliance, investigation |
1174
1175- **No single hot database.** Each repository's recent events live with that
1176 repository, so load spreads across as many objects as there are repos.
1177- **The complete record is files, not rows.** Iceberg on R2 has no practical
1178 size limit and is queried with SQL.
1179- **Audit is a property of every event.** The envelope carries the actor
1180 (person, agent, token or system), the credential used, the request id and
1181 the source address. Audit entries for a workspace are hash-chained, so a
1182 removed or altered entry is detectable, and are written under a retention
1183 lock.
1184- **Delivery is at least once.** Consumers are idempotent on the event id.
1185
1186## Accounts and forge basics
1187
1188- Registration with email verification, sign-in, forgot password (Cloudflare
1189 Email Sending), Turnstile on public forms.
1190- GitHub sign-in, SSH keys, access tokens, active sessions.
1191- Profiles, public and private repositories, repository search (D1 full-text).
1192- Rendered README, syntax highlighting, commit history, diffs.
1193- Transferring a repository between workspaces (by id: its git store key
1194 never moves; every service follows `repo.transferred`; old paths redirect
1195 until reused) and deleting an empty, settled workspace (its slug is
1196 tombstoned, never reissued except to the person whose username it is).
1197

1216
1217## Running g1t yourself
1218
1219g1t.sh runs on Cloudflare, and that does not change. The core is MIT and
1220must also run on anyone's own machine with `docker compose up`. A free
1221core people can self-host is what makes paid hosting worth trusting.
1222Self-hosting never makes hosted worse: hosted code paths keep their
1223behaviour, and a self-hosted adapter sits beside the hosted one. The
1224inventory of every Cloudflare dependency, the design and the risks are in
1225[SELF_HOSTING.md](SELF_HOSTING.md).
1226
1227The approach: the Workers stay Workers, and self-hosted they run in
1228workerd, the open-source Workers runtime. D1, KV and Queues are SQLite on a
1229volume, with the same migrations. Cloudflare-only bindings are replaced
1230by stand-ins:
1231
1232- Artifacts becomes bare repositories served by `git http-backend`;
1233- Email Sending becomes SMTP, through Mailpit;
1234- services that are off answer "off" instead of failing.
1235
1236| Phase | Scope | Estimate |
1237| --- | --- | --- |
1238| 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 |
1239| 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 |
1240| 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 |
1241| 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 |
1242
1243## The submission
1244
1245- **g1t is built on g1t.** This repository is hosted on g1t.sh, its features
1246 are opened as issues and built by racing agents, and it deploys from
1247 Artifacts through Workers Builds. The history is the proof.
1248- **The demo follows one story.** A brief becomes a project; twelve issues
1249 fan out to dozens of agents; agents notice each other, hand off, and
1250 resolve a conflict; reviewers triage; the queue lands everything on
1251 `main`; why-blame explains a line; the portfolio shows where it all
1252 stands. Then the same thing at a thousand agents.
1253- **Judges can try it in a minute.** Open registration on g1t.sh, one-click
1254 import of a GitHub repo, one command to connect Claude Code, a seeded demo
1255 workspace, and a single deploy command for running their own copy.
1256- **The formats are open.** The commit trailers, session format and runner
1257 contract are published so other tools can interoperate.
1258
1259## Build order
1260
1261What is left is ordered by how much it shows the point above, not by forge
1262parity. Forge basics are done well enough; each item below should make the
1263demo's story stronger.
1264
1265Done from this list: the outcome page (a plan's issues as a live graph with
1266cost and a feed of what happened), coordination you can see (agents' issues
1267and comments stand out in the feed; agents hold g1t's tools through a token
1268scoped to one repository), steering a running agent (messages delivered
1269between steps, and at the end), and recording sessions from anyone's own
1270Claude Code (`curl -fsSL https://g1t.sh/install/claude.sh | sh`). Integrations are
1271in: a workspace's own model provider (Anthropic or any Anthropic-compatible
1272endpoint, reached through a model proxy so no sandbox holds a key; its
1273runs pay only their sandbox time), alerts from Sentry, Datadog and signed webhooks
1274that open one issue per problem and can start an agent, and Jira and Linear
1275tickets that agents read, people import, and that hear back. Racing a
1276set number of agents on one issue is dropped: choosing how many agents to
1277use is not something people should have to do.
1278
12791. ~~**Handoffs and questions between agents** as states on the outcome
1280 page.~~ Done: questions and handoffs show as waiting, read, answered,
1281 taken on or declined; since 2026-10-03 an agent asked while it is not at
1282 work is woken to answer, where before the question waited forever.
12832. **Upkeep agents** (above): dependency updates, secret scanning,
1284 vulnerability alerts, code scanning, the security page. No new
1285 infrastructure.
12863. **Deployments on `g1t.page`** (above): previews per pull request,
1287 production on merge, the reviewer agent checking the preview.
12884. **The large run, building 2 and 3.** About 20–30 issues on g1t itself,
1289 built by agents and landed through the queue, for the video: g1t built
1290 on g1t.
12915. **Polish for judges trying it in a minute:** a seeded demo workspace, the
1292 empty states, and the first-run path from sign-up to an outcome landing.
1293
1294Earlier items still open, after those:
1295
12961. Deleting a branch once its pull request merges; approval rules per
1297 path; risk tiers.
12982. Scopes on OAuth grants and access tokens.
12993. Event storage per the design above: per-repo hot log, Iceberg on R2,
1300 hash-chained audit.
13014. CLI with Claude Code hooks to record sessions automatically.
13025. Reviewing and catching up automatically, by policy; required reviews;
1303 risk tiers.
13046. Compare view, proof bundles; handoff between agents.
13057. Projects, mission control, steering; why-blame, digest, timeline.
13068. Context hub, portfolio; automations and integrations (Sentry first).
13079. SSH; bot protection; own keys, endpoints and runners.
130810. Large run (100+ agents across many issues), hardening, demo.
1309
1310Later: code search, mirroring to GitHub, passkeys, SSH
1311on port 22 without the CLI proxy (needs the Workers inbound TCP private
1312beta).
