Defensive security audit skill pack for agentic code review and web application assessment.
Patchman is a skill and plugin bundle for authorized security reviews. It operates in read-first, review-first mode — inspecting code and architecture against OWASP and common appsec failure patterns, then producing structured findings with actionable remediation guidance.
Supported agents: Claude Code · Codex · Cursor · Windsurf · Copilot · Gemini-style skill installers

- OWASP Top 10 classes with code-level evidence
- Broken authentication, authorization, and session management
- IDOR and tenant isolation failures
- Business logic gaps and approval bypasses
- SSRF, XSS, CSRF, injection, and insecure deserialization
- Secret leakage and sensitive data in logs
- Unsafe file upload handling
- Weak headers, insecure defaults, and risky cryptography
- Missing rate limiting and anti-abuse controls
- ORM misuse, N+1 query issues, and cross-tenant data access
- Admin path, webhook, queue, and background job vulnerabilities
Full audit
Run a full security audit on this repo. Prioritize broken access control, unsafe defaults,
tenant isolation, secret handling, and exploitable auth issues. Use the Patchman findings format.
Targeted review
Review only the password reset flow. Focus on token lifetime, replay attacks, host header
trust, user enumeration, and session invalidation after reset.
PR review
Audit this pull request as a defensive security reviewer. Flag regressions, rank by severity
and confidence, and suggest minimal safe patches.
Every finding includes:
- Evidence — specific code or configuration reference
- Severity — based on blast radius and realistic abuse conditions
- Confidence — drops when context is incomplete
- Remediation — specific enough to implement directly
Patchman is for authorized defensive auditing only.
In scope: secure code review, architecture review, configuration review, exploitability analysis in plain language, remediation planning
Out of scope: unauthorized intrusion, exploit weaponization, credential harvesting, malware or persistence guidance, destructive payloads, live attack chains
Patchman infers risk from static code and configuration. It does not replace runtime validation and will request missing deployment, proxy, or identity-boundary context when evidence is insufficient.
