## Most Used Skills (by audit log `skill_run` count)

## Most Effective Skills (by eval score, /100 scale)
| Skill | Avg Score | Scored Runs | Trend |
|-------|-----------|-------------|-------|
| devops-audit | 53 | 1 | flat |
| code-review | 50 | 3 | flat |
| memory-consolidation | 50 | 2 | flat |
| heartbeat | 50 | 1 | flat |
| brainstorming | 50 | 1 | flat |
| content-draft | 50 | 1 | flat |
| backup-skill | 48 | 5 | flat |
| daily-standup | 45 | 3 | flat |
| audit-test-plugin | 45 | 5 | flat — **scores unreliable, all runs failed** |

⚠️ Scores are compressed in a 45–53 band. The eval layer records failed
opencode/Hermes-routed runs as `success: true`, so scores are not a trustworthy
quality signal until routing is fixed.
