Conciseness

The body is dense and tool-specific: every table documents what the bundled scanner actually detects (regex patterns, OWASP mappings, CLI flags, exit codes) rather than explaining concepts Claude already knows. There is no padding, no library tutorials, and no general security-education prose, matching the 'every token earns its place' anchor.

Actionability

The Quick Start gives copy-paste-ready commands covering all common cases (all-checks scan, each individual mode, JSON output with a file path, severity filtering), and the Parameters table documents every flag the bundled script actually supports (verified against scripts/security_scan.py). Output examples make result interpretation concrete. This matches the fully executable, common-cases-covered anchor.

Workflow Clarity

This is a single-action, read-only skill (run one scanner command) and the single action is unambiguous, which per the simple-skill guideline can score 5. Checkpoints are present in the forms that matter here: the Exit Codes table (0/1/2) defines feedback semantics, the Prerequisites section explains the degrade gracefully path when npm/pip-audit is missing, and severity/format flags let the user control results. No destructive or batch mutation is involved, so the validation cap does not apply.

Progressive Disclosure

Structure is good: clear sections (Quick Start, module details, Parameters, Output Format, Exit Codes, Prerequisites) and the only bundle file, scripts/security_scan.py, is real and referenced directly in executable commands. However, the module-detail tables (secret regex patterns, OWASP mappings) are inline reference material that could live in a references/ file, and at ~150 lines the body is somewhat heavier than a pure overview — 'most content appropriately placed, minor organization gaps' fits anchor 4 better than anchor 5's clean overview-plus-split-references shape.

Specificity

The description lists multiple concrete actions: 'dependency vulnerabilities (npm/pip audit)', 'secret leaks (regex and entropy analysis)', and named OWASP anti-patterns 'SQL injection, XSS, or command injection'. It uses third person voice ('Scan code') and matches the comprehensiveness of the score-5 anchor ('Extract text and tables from PDF files, fill forms, merge documents') with no over-claims or buzzwords.

Completeness

It explicitly answers 'what' (three named scanning capabilities with parenthetical methods) and 'when' via an explicit 'Use when the user mentions...' clause with concrete trigger phrases, exactly matching the score-5 anchor pattern. A score of 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

'security scans, vulnerability detection, secret leaks, API keys, OWASP, npm audit, pip-audit, hardcoded passwords, or code security checks' covers natural phrasings users would actually say, including tool names ('npm audit', 'pip-audit'), category terms, and concrete leak types. Coverage is comparable to the anchor example's 'PDF files, PDFs, forms, document extraction, .pdf' breadth; not below it since both technical and colloquial variants are present.

Distinctiveness Conflict Risk

It has a clear niche (static code security scanning) with distinct triggers like 'OWASP', 'npm audit', 'pip-audit', but generic triggers such as 'security scans' and 'code security checks' carry minor overlap risk with broader code-review or general security-audit skills. Mostly distinct with minor overlap risk fits anchor 4 better than anchor 5's 'minimal conflict risk'.
