Conciseness

The body is efficient and assumes Claude's competence, with no explanation of known concepts. Minor trimmable instances remain: step 3 lists 'TODO/TODO' (a duplicated typo where TODO/FIXME was meant), and the Resources section repeats links already given inline in steps 2, 3, and 8 — anchor 4, not the every-token-earns-its-place anchor 5.

Actionability

Concrete guidance throughout: specific patterns ('AKIA...', 'rm -rf /', 'eval()', base64/hex), executable commands ('jq empty .claude-plugin/plugin.json', 'pnpm run sync-marketplace'), an error table with fix commands, and references containing runnable grep/jq/find recipes. The main scan steps describe what to look for rather than giving the commands inline (delegated to references), leaving minor gaps versus anchor 5.

Workflow Clarity

A clear 8-step sequence covers all eight audit categories, with step 1 confirming the target exists and an error-cause-solution table for recovery. Auditing is read-only so the destructive/batch validation cap does not apply, but explicit validation checkpoints within the steps are implicit rather than stated, matching anchor 4 rather than 5.

Progressive Disclosure

References are well-signaled inline and indexed in a Resources section, all one level deep, and every cited file (audit-categories.md, audit-process.md, audit-report-format.md, examples.md, errors.md) exists with content matching its description. Minor organization gaps: ARD.md and PRD.md sit unreferenced in references/, and references/README.md is generic boilerplate — anchor 4 rather than the fully clean anchor 5.

Specificity

The only concrete verb is 'audits'; the phrases 'security vulnerabilities, best practices, AI assistant.md compliance, and quality standards' name audit focus areas rather than several distinct actions (extract/fill/merge style). This matches anchor 3 (domain plus limited concrete actions), not anchor 4 which expects several specific listed actions.

Completeness

Both 'what' (audits plugins for security, best practices, compliance, quality) and 'when' (explicit 'Use when' plus trigger phrases) are present, but the 'what' is garbled ('Audit automatically audits', truncated 'repositor...', and 'AI assistant.md' inconsistent with the body's CLAUDE.md). Anchor 4 (both present, one could be more explicit/cleaner) fits better than 5.

Trigger Term Quality

Natural user phrases are present: 'security scan', 'audit', 'vulnerability', 'security review', 'best practices check'. Coverage is good but misses common variations like 'plugin check' or 'code review', matching anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The domain is scoped to 'AI assistant-code-plugins' repositories, but the triggers 'audit', 'vulnerability', and 'security scan' are generic and would also fire for general security-review or code-review skills. This is 'somewhat specific but could still overlap with similar skills' (anchor 3), not the mostly-distinct anchor 4.
