Analyzes Claude Code session logs to validate skill execution against SKILL.md specs, verifying hooks, subagents, tools, artifacts, and workflow steps.
How this skill is triggered — by the user, by Claude, or both

Post-hoc analysis tool for validating Claude Code session behavior against SKILL.md specifications.
Post-hoc analysis tool for validating Claude Code session behavior against SKILL.md specifications.
Analyze completed sessions to verify:
| Parameter | Required | Description |
|---|---|---|
sessionId | YES | UUID of the session to analyze |
targetSkill | YES | Path to SKILL.md to validate against |
additionalRequirements | NO | Extra validation criteria |
Session files are located in ~/.claude/:
# Main session log
~/.claude/projects/-{encoded-cwd}/{sessionId}.jsonl
# Debug log (detailed)
~/.claude/debug/{sessionId}.txt
# Agent transcripts (if subagents were used)
~/.claude/projects/-{encoded-cwd}/agent-{agentId}.jsonl
Use script to locate files:
${baseDir}/scripts/find-session-files.sh {sessionId}
Check all required files exist before proceeding. If debug log is missing, analysis will be limited.
Read the target SKILL.md and identify:

## Expected Behavior
### SubAgents
- [ ] Explore agent called (parallel, run_in_background)
- [ ] gap-analyzer called before plan generation
- [ ] reviewer called after plan creation
### Hooks
- [ ] PreToolUse[Edit|Write] triggers plan-guard.sh
- [ ] Stop hook validates reviewer approval
### Artifacts
- [ ] Draft file created at .dev-flow/drafts/{name}.md
- [ ] Plan file created at .dev-flow/plans/{name}.md
- [ ] Draft file deleted after OKAY
### Workflow
- [ ] Interview Mode before Plan Generation
- [ ] User explicit request triggers plan generation
- [ ] Reviewer REJECT causes revision loop
The debug log (~/.claude/debug/{sessionId}.txt) contains detailed execution traces.

1. Find session files
2. Parse SKILL.md → Expected: Explore, gap-analyzer, reviewer, hooks
3. Analyze debug log → Extract actual calls
4. Verify artifacts → Check .dev-flow/
5. Compare → Build verification table
6. Generate report → PASS/FAIL with details

Useful for debugging unexpected skill execution or verifying correct workflow completion.
Reviews Claude Code skill performance in sessions: preprocesses JSONL logs with Node script, analyzes via Sonnet sub-agent, recommends SKILL.md improvements.
Generates an in-chat session report from the active or named transcript — every tool call, sub-agent delegation, and file edit, with diagnostics for missed parallelism, redundant work, and over-serialization.
