Lists multiple specific concrete actions: 'fix security vulnerabilities', 'Researches authoritative sources', 'applies fixes grounded in the user's specific codebase context'. Also enumerates specific vulnerability types (SQL injection, XSS, CSRF, SSRF, path traversal, command injection, authentication bypass, authorization flaws, prompt injection).

Clearly answers both what ('fix security vulnerabilities', 'Researches authoritative sources and applies fixes') AND when ('Activates when the user shares a DryRunSecurity comment...or asks for help fixing any security finding'). Explicit trigger guidance is provided.

Excellent coverage of natural terms users would say: 'DryRunSecurity', 'GitHub PR', 'GitLab MR', 'security finding', plus specific vulnerability names (SQL injection, XSS, CSRF, etc.) that users would naturally mention when seeking help.

Clear niche focused on DryRunSecurity findings and specific security vulnerability types. The combination of the tool name 'DryRunSecurity' and the enumerated vulnerability categories creates distinct triggers unlikely to conflict with general coding or documentation skills.

The content is lean and efficient, avoiding explanations of basic security concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context.

Provides concrete, executable guidance with specific tool names (Glob, Grep, Read, Edit, WebFetch), exact search patterns, a clear before/after code example, and specific commit format. The table of config files to search is immediately actionable.

Clear 5-step sequential process with explicit checkpoints ('Do NOT propose a fix until complete', 'Do NOT rely on memorized examples'). Each step has specific actions and the workflow includes verification in Step 5.

Well-structured overview with clear one-level-deep references to supporting files (FINDING_FORMAT.md, VULNERABILITY_TYPES.md, DRYRUN_FILTERING.md). Content is appropriately split between quick reference in main file and detailed references elsewhere.
