Names the domain (security/vulnerability hunting) and describes the focus area (remotely reachable, bounty-worthy vulnerabilities), but doesn't list specific concrete actions like 'analyze input validation, check authentication flows, test for injection flaws'.

The 'what' is reasonably covered (hunt for exploitable security issues in repos), but there is no explicit 'Use when...' clause or equivalent trigger guidance, which caps this at 2 per the rubric guidelines.

Includes some relevant terms like 'security issues', 'bounty-worthy', 'vulnerabilities', and 'repositories', but misses common user phrases like 'bug bounty', 'pentest', 'security audit', 'code review for security', 'CVE', 'OWASP'.

The description carves out a clear niche: bounty-worthy, remotely reachable vulnerabilities in repositories. The distinction from generic code review or local-only security scanning is explicitly stated, making it unlikely to conflict with general code analysis skills.

Every section earns its place. The tables are dense and informative, the skip list prevents wasted effort, and there's no explanation of concepts Claude already knows. No padding or unnecessary context.

The workflow steps are clear and the report template is useful, but guidance is mostly directional rather than executable. The semgrep command is the only concrete command; the triage loop and code-reading steps lack specific techniques or code examples for tracing user input to sinks.

The 7-step workflow is clearly sequenced from scope check through duplicate check. The quality gate serves as an explicit validation checkpoint before submission, and the triage loop includes a filter-then-verify feedback pattern. Steps are logically ordered with clear decision points.

For a skill of this size and scope, the content is well-organized into clearly labeled sections (in-scope patterns, skip list, workflow, report structure, quality gate) without being monolithic. No external references are needed given the self-contained nature of the guidance.
