Analyzes and optimizes prompts using BP-001~008 patterns and a gated 3-step flow. Use when "optimize this prompt", "review prompt quality", "analyze prompt issues", or creating/reviewing rashomon skill content.
Project-specific prompt optimization knowledge management. Use when storing or retrieving learned patterns from comparisons. Provides schema, extraction criteria, capacity management, and retention scoring.
Compares original and optimized prompts through repeated blind paired execution in git worktrees. Use when evaluating prompt improvement effects or learning prompt engineering through concrete examples.
Creates or updates Claude Code skills through interactive dialog, then evaluates effectiveness with sequential paired comparisons. Use when creating new skills, updating existing skills, or evaluating skill quality.

Cleanup Triggers:
Key: To achieve true parallel execution, spawn both Task calls in a single message.
The calling command determines which agents to invoke and how to structure the Task calls. This skill provides only the worktree infrastructure.
| Scenario | Behavior |
|---|---|
| Creation fails | Report git error, suggest checking repository state |
| Cleanup fails | Log warning, attempt orphan cleanup on next run |
| Unlocked orphan | Remove registered Rashomon worktree after 1 hour |
| Crashed locked run | Remove after owner disappearance plus orphan age, or after lease expiry |
| Active long run | Set RASHOMON_LEASE_SECONDS before creation so the lease covers the run |
| Exit Code | Meaning |
|---|---|
| 0 | Success |
| 1 | Not a git repository |
| 2 | Creation failed |
| Exit Code | Meaning |
|---|---|
| 0 | Success (or nothing to clean) |
| 1 | Not a git repository |
| 2 | Cleanup partially failed |
