Retrospective

Analyze evaluation patterns across completed plans, identify recurring failures, and auto-apply checklist evolution — the downstream consumer of executing-plans Phase 4 "Checklist Evolution Candidates". The user reviews post-commit via git show docs/retros/checklists/.

Recommended: run wrapped in /goal

Launch it under Claude Code's built-in /goal (v2.1.139+) — a retrospective can span multiple turns:

/goal "Claude has narrated a successful checklist-evolution commit (with commit hash) and stated the retrospective is complete" /superpowers:retrospective <plan-paths>

/goal is a user-typed outer wrapper (a skill cannot enable it for itself mid-run), and its evaluator judges only what Claude narrates in the transcript — phrase the condition against narrated output (the commit-hash line, an explicit completion statement), never filesystem state. Full semantics and condition phrasing: ../../skills/references/goal-wrapper.md.

Pre-Check (run first, in order)

A. INSUFFICIENT-POST-PLAN advisory (informational)

Read the most recent plan_completed event from docs/retros/plans-completed.jsonl. If hours_since_completion < 24h AND bash "${CLAUDE_PLUGIN_ROOT}/lib/post-plan-diff.sh" summary <completion_commit> <files...> returns total == 0, output the INSUFFICIENT-POST-PLAN reminder verbatim (see ./references/post-plan-diff.md §Pre-Check A) and proceed to Phase 0 — do NOT pause. Skip silently when completion_commit is missing.
