-## Skill: update-skill-index
-**Date:** 2026-04-02
-**Skill:** update-skill-index
-**Purpose:** Keeps `_skill-index.md` accurate by reconciling it against skills on disk. Adds missing entries, garbage-collects orphaned entries, refreshes stale triggers. Built via skill-creator with 3 evals (add, garbage-collect, no-op). With-skill pass rate: 100%; baseline: 83%. Key differentiator: skill enforces a proposed-diff step before writing.
-**Triggers:** "update the skill index," "sync the skill index," "refresh the skill index," "clean up the skill index," "garbage collect the index"
-**Files created:** skills/update-skill-index/SKILL.md
