Conciseness

The ~45-line body is lean and dense: 7 iron rules, 8 procedure steps, a grade table, options, and references — every token earns its place and nothing explains concepts Claude already knows. Firmly the score-5 anchor ('lean and efficient; assumes Claude's competence').

Actionability

Guidance is largely executable: concrete processing order ('D → A → I → G → H → F → B → C·J → E 순서로 문단 단위 처리'), numeric thresholds ('변경률 30% 초과 = 경고, 50% 초과 = 작업 중단·롤백'), and an exact output contract ('`_workspace/{run_id}/final.md`', 정확히 하나의 `<!-- HUMANIZE-SUMMARY -->` 블록). However the A–J category IDs and S1/S2/S3 severity scale that the thresholds and grades depend on are never defined in-body, and the rulebook that defines them ('quick-rules.md') does not exist at the referenced path — more than the score-5 'copy-paste ready, covers the common cases' bar.

Workflow Clarity

The 8-step sequence is explicit with a validation checkpoint (step 6, quick-rules 자체검증 6항) and a feedback loop for error recovery ('위반 edit만 롤백해 최대 한 번 다시 처리한다'), plus abort/rollback thresholds at 50% change rate. This matches the score-5 anchor (clear sequence, explicit validation, retry loop) rather than score 4's 'minor validation gaps'.

Progressive Disclosure

References are well-labeled and one level deep ('슬림 룰북', '분류 체계 본진', '윤문 처방'), but all three point to `../../../skills/humanize-korean/references/*.md` — a path outside this bundle — and no `references/` directory exists at all, so none of the referenced files resolve. Navigation is signaled but broken, fitting score 3 ('references present but not clearly/signally usable, organization could improve') rather than score 4's 'minor organization gaps'.

Specificity

The description lists multiple concrete actions — '탐지·분류해…재작성한다' (detects, classifies, rewrites) — and comprehensively names the pattern categories (번역투, 영어 인용 과다, 기계적 병렬, 피동 남용, 접속사 남발, 리듬 균일, 이모지/불릿 과다 등 10대 카테고리 70개 패턴) with an explicit scope constraint ('내용은 한 글자도 건드리지 않고 문체·리듬·표현만 자연스럽게 재작성한다'). Coverage is comprehensive with no noticeable gaps, matching the score-5 anchor rather than the score-4 'minor gaps' anchor.

Completeness

Both 'what' (detect/classify 70 AI-tell patterns across 10 categories and rewrite style/rhythm/expression only, preserving meaning) and 'when' are explicitly and concretely answered via the '트리거 — …' clause with concrete phrases, plus boundary exclusions ('단순 맞춤법 교정·번역·내용 추가는 대상 아님'). This clearly matches the score-5 anchor, not score 4 where 'when' could be more explicit.

Trigger Term Quality

Explicit natural trigger phrases users would actually say are provided in both Korean and English: '"AI 티 없애줘", "AI 윤문", "ChatGPT 티 제거", "번역투 고쳐", "사람이 쓴 것처럼", "humanize Korean"'. This covers synonyms and register variations comprehensively, matching the score-5 anchor.

Distinctiveness Conflict Risk

A clear niche (removing AI tells from Korean text) with distinct triggers and explicit exclusions separating it from spell-checking, translation, and content-addition skills. Minimal conflict risk, matching the score-5 anchor.
