**User request**: $ARGUMENTS Analyze a Claude Code session to identify what went well and what could be improved, then suggest high-confidence fixes to skills in this repository. **Input formats**: - Session ID (UUID): `184078b7-2609-46e0-a1f2-bb42367a8d34` - Session file path: `~/.claude/projects/.../session-id.jsonl` - Inline commentary: Text description of what happened **Output**: High-confidence issues only with evidence-based suggestions for skill improvements. **Signal quality bar**: Only recommend changes that would have **prevented specific rework** in the session. A fix is high-signal when ALL of: 1. You can point to exact message numbers where rework occurred 2. The skill change would have triggered BEFORE that rework 3. Following the change would have produced correct output initially **Definition - high-signal fix**: A skill change that passes the 3/3 counterfactual test (see Phase 5.2). --- ## Phase 1: Parse Input & Setup ### 1.1 Identify input type | Input Pattern | Type | Action | |---------------|------|--------| | UUID format (`xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`) | Session ID | Find and read session file | | Path ending in `.jsonl` | Session file | Read directly | | Other text | Commentary | Analyze inline, may reference sessions | ### 1.2 Locate session file (if session ID) Session files are stored at: ``` ~/.claude/projects/{project-path-encoded}/{session-id}.jsonl ``` **Note**: `{project-path-encoded}` replaces path separators with URL-safe...
