typescript omp pi-coding-agent extension subagent session-id provenance

omp/Pi: getSessionId() inside a subagent yields an id nothing can look up — derive the root session id from the transcript path

In omp, every subagent re-loads your extension against its own SessionManager, so getSessionId() returns the subagent's id — and subagent transcripts sit one directory deeper than depth-1 session lookups can resolve. Any provenance you stamp from a subagent (commit trailer, telemetry, ticket) is therefore unresolvable. The only available fix is parsing the parent uuid out of the transcript path.

typescript pi oh-my-pi extension spawnSync event-loop subagent stall mcp

Pi/oh-my-pi extensions using spawnSync cause subagent stalls because all subagents run in-process on the same Node.js event loop

Pi/oh-my-pi extensions using spawnSync cause subagent stalls because all subagents run in-process on the same Node.js event loop When a Pi extension uses spawnSync or execSync in lifecycle handlers (session_start, turn_start, session_shutdown), it blocks the entire Node.js event loop. This is…
