retro
Explicit retrospective of a coding session with evidence-backed suggestions for future work.

Review the current coding session by default. Review another session only when the user specifies it and the evidence is accessible. Use the available writing-for-agents guidance when suggesting agent instructions.
- Read the session's primary evidence and the repository's current instructions, check commands, and relevant tooling. Separate observed friction from conjecture.
- Look for concrete improvements to navigation pointers, information access, instructions, tool economy, and checks. Recommend a check only when an observed mistake could have been caught and existing checks do not cover it. A missing CI job alone is not a finding.
- Rank suggestions by impact and cost. For each, cite the session evidence, explain the mechanism, and give a concrete next action. State when evidence is insufficient.
Reviewers may need to inspect code and history to understand a change; do not assume a diff is enough. Treat mechanical checks, rules, and documentation as options whose costs must be justified by the observed failure.
This is a read-only suggestion workflow. Present proposed changes in chat; edit AGENTS.md, code, CI, memory, or issues, send messages, and start background tasks only when separately authorized. Existing explicit authorization remains effective.
