Project configuration

This repository is the project's executable configuration. worker.ts is the default project worker (fetch plus processEvent). It declares packaged apps such as GithubAiLinter, GuestbookApp, and TodoApp; project-owned app source lives under apps/, and the packaged linter reads editable policy from rules/.

The seeded repo also contains AGENTS.md (born with this file's content, then independent): worker.ts injects AGENTS.md's contents into every agent's context automatically (at agent birth and again on every config-repo commit — see #syncAgentsMdContext). Write stable project facts into AGENTS.md and every agent learns them; keep it lean, because it rides every LLM request of every agent.

Project lifecycle hooks#

The processEvent switch in worker.ts exposes the lifecycle events. Each case is ordinary userspace TypeScript: call through this.itx directly, such as await this.itx.scheduler.set(...). The getter memoizes the native Workers RPC promise-proxy for that stateless invocation, so nested calls pipeline without first awaiting the project root. There is no configuration-reconciliation framework around them.

• project/heartbeat-triggered is the ordinary event appended by that Scheduler script. Its payload is only { scheduleKey }. Put arbitrary periodic itx calls directly in this case.
• root stream/woken is available for work that should run when the project stream wakes after hibernation or an OS deployment.
• project/worker-updated is the config-application hook. The project-creation terminal publishes the first one after probing the trusted seed worker; it does not react to the raw seed commit. For each later config repo commit, the platform appends another only after the current default worker has built, loaded, and answered a readiness probe. If several commits land quickly, a later HEAD may reconcile earlier commit facts too. This is deliberately a reconcile-current-config hook, not an exact per-commit activation callback. The seeded example calls itx.scheduler.set(...) here to install one 15-minute heartbeat.
• project/created is the first userspace event. The root worker subscription is installed immediately before it in the same atomic append, so the seeded worker receives it after the platform creation saga has completed. This template uses it to create /agents/onboarding, install the template-local ONBOARDING.md prompt, trigger the agent's first turn, and navigate each connected /clients/os-app/** browser client that is still on the new project's landing page to its chat.

project/create-requested remains platform-only: it precedes the userspace worker subscription. The terminal project/created certificate includes the birth configuration, including config.configRepoTemplate when the project was created from a public template.

The heartbeat uses the Scheduler's native recurrence shape: { every: seconds }, { cron, timezone? }, or { at: ISO timestamp }. Copy the literal scheduler.set(...) call to add another schedule, use { every: 1 } in a fast test project, or delete it when a project needs no heartbeat. set(...) leaves a matching schedule's clock, run count, and defining event untouched.

Nothing interprets the source file as desired state. Changing or deleting an existing schedule is explicit code too: call scheduler.set(...) or scheduler.cancel(...) from whichever lifecycle case should apply the change. Missed interval occurrences coalesce; the Scheduler does not backfill one event per missed interval. The scheduler execution ID is the heartbeat append's idempotency key.
