# Retro: #97 — Document coexistence with pi-subagent extensions and their tool deny mechanisms

## Final Retrospective (2026-05-05T21:00:00Z)

### Session summary

Docs-only issue adding a `### Coexistence with Subagent Extensions` section to `README.md` under `## Technical Details`.
The plan→build→ship pipeline executed cleanly across three template invocations with no rework, corrections, or deviations.
Released as part of v5.2.1.

### Observations

#### What went well

- Clean single-step execution: plan, implement, lint, commit, push, CI green, close, merge release PR — no friction at any stage.
- The issue body was well-structured with a clear task list and a table of the three subagent extensions, which translated directly into the README content.

#### What caused friction (agent side)

- No friction observed.

#### What caused friction (user side)

- No friction observed.
