Use when the user has run multiple evaluation skills and wants a comprehensive analysis — maturity assessment, cross-skill signals, trends, prioritized actions, and an executive summary. Also use when the user mentions eval health check, evaluation audit, ship readiness, evaluation maturity, or "how good is my evaluation system itself." This is a read-only analysis skill.

Eval Report
Synthesize everything from your evaluation journey into a comprehensive report.
This skill is read-only — it analyzes what exists, doesn't create new graders or datasets.
When to Activate
You've run 2+ evaluation skills and want the big picture
You need to report evaluation status to non-technical stakeholders
You're making a ship/no-ship decision and need evidence
The evaluation system has been running for a while — time for a health check
Checklist
You MUST create a task for each item and complete them in order:
Inventory scan — catalog everything in eval-design.md + runs/ history
Maturity assessment — 5 dimensions × 4 levels
Cross-skill signal synthesis — consistent findings + contradictions
