Local CI Dev

Local CI (dev build)

Run local CI against the in-tree dev build (pnpm local-ci-dev) to verify changes to this repo before completing work.

This skill relies on two pi-native tools added by .pi/extensions/background-shell.ts: bash_background (start a command, return immediately) and monitor_wait (block until the log matches a pattern or the task exits). If those tools aren't available in your pi, load/reload the extension — /reload if you're already in a session, or relaunch pi — before continuing.

Steps

1. Start local-ci in the background with bash_background, with the NDJSON event stream enabled:

   { "command": "pnpm local-ci-dev run --all -q -p --json" }
   

   This returns { taskId, outputFile, pid } without blocking. Because stdout isn't a TTY, the launcher detaches automatically: the foreground process exits 77 the moment a step pauses, while the worker keeps the container alive for retry.

2. Wait for a pause or completion with monitor_wait, matching the NDJSON event discriminators (silence is not success — a crash or hang with a success-only filter looks identical to still-running):

   {
     "taskId": "<from step 1>",
     "pattern": "\"event\":\"(run\\.paused|run\\.finish)\"",
     "timeoutMs": 600000
   }
   

   monitor_wait returns when any of the following happens:

   • the regex matches a new line → stoppedBecause: "match", inspect matches. A run.paused line carries the runner name + retry_cmd; a run.finish line carries status: passed|failed.
   • the task exits → stoppedBecause: "exit", inspect state (succeeded or failed) and exitCode. Exit code 77 means a step paused — treat it like a run.paused match.
   • the timeout elapses → stoppedBecause: "timeout", loop back and call monitor_wait again (it resumes from the previous byte offset automatically)

3. On success (run.finish with status: passed, or state: "succeeded"), you're done.

4. On failure (run.paused match or exitCode: 77), read the full output file for details:

   tail -n 200 <outputFile>
   

   CI was passing before your work started, so the failure is caused by your changes. Fix the issue in your code, then retry the failed runner — again via bash_background + monitor_wait:

   pnpm local-ci-dev retry --name <runner-name>
   

   If the fix requires re-running from an earlier step:

   pnpm local-ci-dev retry --name <runner-name> --from-step <N>
   

   Repeat until the job passes.

5. Once all jobs have passed, you're done.
