# Pi subagent compact and expanded monitor
|
|
|
|
## Question
|
|
|
|
Implement the approved compact and expanded Pi-native subagent monitor behavior.
|
|
|
|
## What to build
|
|
|
|
The existing subagent widget should become the approved monitor.
|
|
Compact mode should show aggregate counts by status rather than one row per child.
|
|
Expanded mode should show one row per visible child with label, lifecycle state, elapsed time, and last activity or result marker.
|
|
The monitor should make running, queued, settling, completed, failed, timed-out, and cancelled work distinguishable without requiring a blocking wait or JSON notification dump.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [x] Compact mode shows aggregate counts by meaningful status groups.
|
|
- [x] Expanded mode shows one row per child with label, state, elapsed time, and last activity or result marker.
|
|
- [x] Rows truncate cleanly to terminal width.
|
|
- [x] Failed, timed-out, cancelled, completed-with-result, running, queued, and settling children are visually distinguishable.
|
|
- [x] The existing UI toggle still works.
|
|
- [x] Tests cover compact and expanded rendering.
|
|
|
|
## Implementation Notes
|
|
|
|
Keep compact mode ambient.
|
|
Do not make it a transcript or result preview surface.
|
|
|
|
Implemented on branch `subagent-labels` in commit `aafc68e feat(pi): render subagent monitor views`.
|
|
Compact rendering now aggregates visible children into queued, running, settling, completed, failed, timed out, cancelled, and orphaned groups.
|
|
Expanded rendering now emits one truncated row per visible child with an icon, state, elapsed time, label, and activity/result/error marker.
|
|
Verification passed with `nix shell nixpkgs#nodejs_24 nixpkgs#tsx -c tsx --test modules/agents/pi/extensions/subagents/ui.test.ts modules/agents/pi/extensions/subagents/supervisor.test.ts modules/agents/pi/extensions/subagents/runner.test.ts modules/agents/pi/extensions/subagents/config.test.ts`.
|
|
Review found no blocking findings.
|
|
The independent test-writer subagent was read-only, so the implementation agent authored the final tests after recording the blocked TDD attempt.
