Conciseness

At ~439 lines the body is mostly efficient and does not explain concepts Claude already knows, but it suffers noticeable duplication — the flavor keyword table and opening-line table each appear twice (lines 139-155 and 177-192) and Owner意识 is repeated (lines 101-107 and 200-216) — so it could be meaningfully tightened. Not below 3 because the padding is redundant protocol detail rather than generic over-explanation.

Actionability

Provides concrete executable templates ([PUA-DIAGNOSIS] line, [PUA-CHECKPOINT] schema, sub-agent spawn snippet, feedback.jsonl format), explicit failure-count-to-level tables, and a checkable 7-item checklist; minor gaps keep it just below copy-paste-perfect.

Workflow Clarity

The pressure-escalation L0-L4 sequence, the 6-step confidence-gating loop with explicit validate→fix→retry feedback, and the mandatory L3 7-item checklist provide clear sequencing with explicit validation checkpoints and error-recovery loops.

Progressive Disclosure

SKILL.md is an overview with clearly signaled one-level-deep references (all real files in references/, each annotated with when to load it), but a fair amount of content (full flavor tables, keyword libraries) is inlined that could live in flavors.md, leaving minor organization gaps.

Specificity

Names concrete actions ('coaching', 'evidence/completion check/test before done', 'Ding-style workplace reminders') and several trigger behaviors, but frames most content as trigger conditions rather than distinct performed actions, leaving minor coverage gaps versus the comprehensive 5-anchor.

Completeness

Explicitly answers both what ('PUA/try-harder productivity coaching') and when (a long explicit trigger list plus a negative-boundary clause 'Do not use for calm first-attempt requests') with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage in both English and Chinese ('try harder', 'again??', 'why still failing', '别摆烂', '证据呢', '闭环', '自嗨') including synonyms and slang, exactly matching the comprehensive-coverage-with-synonyms anchor.

Distinctiveness Conflict Risk

Clear niche (aggressive workplace-flavored productivity coaching) with highly specific bilingual triggers and an explicit exclusion clause, yielding minimal conflict risk with other skills.
