Retro: #98 — Explore a shared permission frontmatter convention for pi-subagent extensions

Final Retrospective (2026-05-05T23:35:00Z)

Session summary

Planned, implemented, and shipped a docs-only change for issue #98. Delivered two guide documents (docs/guides/permission-frontmatter-for-subagent-extensions.md and docs/guides/upstream-issue-template.md) plus linking from README.md and docs/architecture/target-architecture.md. Released as v5.3.1 with no rework or corrections.

Observations

What went well

• All four prerequisites (#78, #29, #96, #97) were verified closed in a single parallel gh issue view call — efficient context gathering.
• Existing docs (docs/subagent-integration.md, docs/event-api.md) were read before writing the guide, so content was grounded in actual implementation rather than invented.
• The three-step build plan mapped 1:1 to commits with no deviations.
• CI passed on first push; release-please PR was MERGEABLE/CLEAN and merged without issues.

What caused friction (agent side)

• None observed. The issue was well-scoped, all prerequisites were landed, and the deliverable was unambiguous documentation.

What caused friction (user side)

• None observed. The issue body provided clear tasks, explicit prerequisites, and no ambiguous design choices.
