# Sync Skill Cache

> Sync the Logic-Lens working-copy skills/ into the installed plugin cache so content-evals test the EDITED skill, not the last published one. ALWAYS run this after editing any skills/**/SKILL.md or guide/_shared file and BEFORE running content-evals — otherwise the eval silently grades stale content and every token is wasted. Also use to verify the cache is in sync ("is the cache fresh?", "did my…

## About

# sync-skill-cache

content-evals invoke each skill through Claude Code's plugin mechanism, which loads from
`~/.claude/plugins/cache/logic-lens-marketplace/logic-lens//skills/` — **not** the
repo's `skills/`. Editing `skills/` changes nothing the eval sees until you copy it into the
cache. This is the single most expensive footgun in the iteration loop: skip it and you grade
the previous skill while believing you tested your change.

## Steps

1. **Sync + verify** from the repo root:
   ```bash
   bash .claude/skills/sync-skill-cache/scripts/sync-cache.sh
   ```
   The script reads the active version from `package.json`, rsyncs `skills/` into the matching
   cache dir (`--delete`, so removed files are removed in the cache too), then diffs the two to
   confirm they are byte-identical. It prints `OK …` on success.

2. **If it prints `DRIFT` or a missing-cache error:** do not run evals. The two common causes:
   - The cache dir for the current `package.json` version doesn't exist (plugin not installed at
     this version) — reinstall/refresh the plugin, or check you didn't just bump the version
     without refreshing the cache.
   - rsync was blocked — rerun and read the diff list it prints.

3. **Verify-only mode** (no copy) to answer "is the cache fresh?":
   ```bash
   bash .claude/skills/sync-skill-cache/scripts/sync-cache.sh --check
   ```

This skill is the mandatory gate between editing a skill and grading it. The `iterate-skill`
orchestrator calls it automatically; run it by hand whenever you edit a skill outside that loop.
