Security Review

When to use

• Use for a full codebase security review with prioritized findings, remediation guidance, and a formal report.

Inputs

• Target repository path (first argument after invocation).
  • Example: $security-review /path/to/repo
• Security knowledge base source:
  • Rules are sourced from Project CodeGuard, an open-source, model-agnostic security framework by CoSAI/OASIS.

If the repo path is missing or unclear, ask the user for it before proceeding.

Workflow

1. Load the security knowledge base from Project CodeGuard

   • First read the Security_Code_Reviewer_Guidelines.md file bundled with this skill. Use its purpose and rule-loading strategy to guide the review.

   • Load all core security rules from Project CodeGuard:

     https://github.com/cosai-oasis/project-codeguard/tree/main/sources/rules/core

     These are mandatory foundational rules that must be loaded for every review.

   • Load relevant OWASP rules for the detected tech stack from:

     https://github.com/cosai-oasis/project-codeguard/tree/main/sources/rules/owasp

     Only load OWASP rules that match the target repository's technology stack.

2. Perform deep code analysis

   • Review the repository line by line.
   • Focus on: injection flaws, authn/authz, hardcoded secrets, crypto misuse, SSRF, path traversal, RCE vectors, XSS/CSRF, unsafe deserialization, insecure defaults/configuration, and supply chain issues.

3. Produce the report in markdown.

Report requirements

• Executive Summary
  • Total findings by severity (Critical/High/Medium/Low/Info)
  • Top 5 most critical issues
  • Overall security posture
• Detailed Findings (for each issue)
  • Title, Severity, Rule Reference(s), Location, Code Snippet
  • Description, Impact, Remediation (with examples), References
• Findings by Category
• Recommendations
  • Immediate actions, short-term (1-3 months), long-term improvements, tooling/process suggestions
• Appendix
  • Files reviewed, rules applied/coverage, methodology notes

Output

• Save the report to:
  • ./security_report/sec_review_<repo-name>_<YYYY-MM-DD_HH-mm-ss>.md
  • Use the target repo folder name for <repo-name> and replace spaces with -.
  • Write to the security_report folder in the current working directory.
