k-skill-cleaner

Use this skill when the user wants to slim down a K-skill bundle, find skills they never use, or make an evidence-backed deletion shortlist instead of deleting directories by guesswork.

Safety contract

Do not delete skills automatically. Produce a ranked recommendation first, then make deletions only after the user explicitly approves the shortlist.

Treat trigger counts as best-effort signals, not absolute truth. Different agents store transcripts differently and may rotate or omit logs.

Protect any skill the user marks as "keep", even if its trigger count is zero.

Prefer removing whole root-level skill directories only after checking README/docs/install references in the same change.

Interview first

Ask a compact interview before scanning or recommending deletion:

어떤 에이전트를 주로 쓰나요? (Claude Code, Codex, OpenCode, OpenClaw/ClawHub, Hermes Agent, 기타)

절대 지우면 안 되는 스킬은 무엇인가요?

본인이 절대로 쓰지 않는다고 확신하는 스킬은 무엇인가요?

최근 30/90/180일 중 어떤 기간의 사용 흔적을 우선 볼까요? helper 실행 시 --days 또는 --since로 반영합니다.

추천만 원하나요, 아니면 승인 후 실제 삭제까지 원하나요?

Trigger count sources by agent

Agent

Reliability
Notes

Claude Code
~/.claude/projects/**/*.jsonl, ~/.claude/transcripts/**/*.jsonl
best-effort
Look for skill-trigger events, $skill-name mentions, and SKILL.md loads.

Codex
~/.codex/sessions/**/*.jsonl, ~/.codex/log/**/*.log, .omx/logs/**/*.log
best-effort
Look for routed skill names, explicit $skill invocations, and skill file reads.

OpenCode
~/.local/share/opencode/**/*.jsonl, ~/.config/opencode/**/*.jsonl
best-effort
If local schema differs, ask the user for an exported transcript or usage JSON.

OpenClaw/ClawHub
~/.openclaw/**/*.jsonl, ~/.clawhub/**/*.jsonl if present
manual-confirm
No stable public local trigger-count schema is assumed; prefer exported stats when available.

Hermes Agent
~/.hermes/**/*.jsonl, ~/.config/hermes/**/*.jsonl if present
manual-confirm
No stable public local trigger-count schema is assumed; prefer exported stats when available.

Local helper

From an installed standalone skill, run the deterministic helper from the k-skill-cleaner skill directory. In a full repository checkout, the compatibility wrapper at scripts/k_skill_cleaner.py accepts the same options.

python3 scripts/k_skill_cleaner.py \
  --skills-root . \
  --scan-default-logs \
  --days 90 \
  --never-use blue-ribbon-nearby,lotto-results \
  --keep k-skill-setup,k-skill-cleaner

For agent exports or hand-curated counts, pass a JSON object mapping skill name to trigger count:

python3 scripts/k_skill_cleaner.py --skills-root . --usage-json usage-counts.json --days 90

--days and --since filter scanned log records only. --usage-json values are already-aggregated counts, so prepare/export that JSON for the same time window before passing it to the helper.

The helper prints JSON with:

skill_count: number of root-level skills discovered.

candidates: ranked remove or review candidates with trigger_count and reasons.

agent_usage_sources: the agent-specific paths and caveats above.

time_window: the effective --since/--days cutoff and mtime fallback caveat.

usage_json: whether imported counts were merged and the pre-windowing caveat.

scanned_logs: how many readable log files were scanned and which paths contributed best-effort evidence.

safety: reminder that no files were deleted.

Recommendation policy

remove: user explicitly marked the skill as never used. Mention any zero/low trigger evidence as supporting context.

review: trigger count is zero or below the selected low-usage threshold, but the user did not explicitly ask to remove it.

keep: user-protected skills and actively triggered skills.

When reporting, group recommendations like this:

삭제 후보 — interview says never used, with trigger evidence.

검토 후보 — zero/low trigger count only.

보존 후보 — protected or recently used.

통계 한계 — which agents had no readable logs and require manual export.

If deletion is approved

Remove the skill directory.

Remove README table/list entries and docs/features/<skill>.md links.

Remove docs/install.md --skill <skill> entries.

Remove package/workspace/test references only if the skill owns those files.

Run npm run lint, npm run typecheck, and npm run test (or npm run ci for packaging/release changes).
