# skill-refiner
The catalog's weeding pass. Absorption (skill-updater, skill-author
hardening) makes the catalog *grow* by default; this skill is the
counterweight that keeps it lean: it measures bloat instead of feeling it,
hunts duplication across skills rather than within one, re-verifies dated
facts before they rot, and asks the question no addition-focused session
asks — "which of these skills earned its context cost?" The research this
skill distills from (MUSE-Autoskill's merge-on-overlap + prune-on-disuse,
Claude Code's least-invoked-first description dropping, Anthropic's
"smallest set of high-signal tokens" principle) all converges on the same
posture: a knowledge base that only ever adds is degrading, just slowly.
## When to use this skill
- End of a skill-updater absorption run — skill-updater invokes a scoped
refine over the skills it just touched (its final step routes here).
- Periodically over the whole catalog: roughly monthly, or after every 2-3
app builds, or when the skills list feels heavy — 'refine the skills',
'check skill bloat', 'prune the skills'.
- Before a plugin release/tag, as the release-readiness sweep.
- When a specific smell appears: two skills answering the same question,
a skill that never fires, a version fact that reads stale.
- Cross-references — go to the sibling skill instead when the task is:
- Folding a session's learnings into skills → `skill-updater` (it feeds
this skill, not the reverse).
- Writing a new skill,
