Conciseness

Mostly lean and assumes Claude's competence (it delegates per-step detail to reference files rather than re-explaining), with only minor spots that could be trimmed such as the 'when to use' rationale and repeated caveats.

Actionability

Gives concrete, executable guidance — the exact rg flags (`rg --multiline --pcre2`), the six permission shapes, the suppression comment syntax, and the report template — with only minor gaps like omitting exact wp-cli commands in the body.

Workflow Clarity

A clearly sequenced seven-step procedure with explicit PASS/WARN/FAIL verdict rules, validation checkpoints (static-only FAIL, runtime-only WARN, single-FAIL escalation), a feedback-loop suppression mechanism, and a debugging section for error recovery.

Progressive Disclosure

The body is a concise overview that points one level deep to six real reference files (all verified present) each cited in context at the matching step, plus cross-references to sibling skills; no nested or buried references.

Specificity

Lists several concrete actions (enumerate abilities, check callback behavior vs annotation claims, validate permissions/schemas, validate audit docs), with minor gaps such as leaving 'curated inputs' unspecified.

Completeness

The 'what' is clear and concrete, but there is no 'Use when...' clause or equivalent explicit trigger guidance; the guideline caps completeness at 3 for a missing explicit when.

Trigger Term Quality

It uses domain-internal jargon ('Abilities API', 'readonly-but-writes', 'annotations', 'permissions') rather than the natural phrases a user would utter ('verify my plugin', 'abilities audit'), missing common synonyms.

Distinctiveness Conflict Risk

The 'Abilities API' niche and the adversarial readonly-but-writes framing make it mostly distinct from sibling skills, with only minor overlap risk against wp-abilities-audit.
