What it does

“Define, review, or update SECURITY.md guidance for a repository or component. Use when the user wants to clarify what Codex Security should review, what is out of scope, which security properties must hold, or whether existing guidance still matches the code.”
The author's description, from SKILL.md

Generated summary from the skill's own text

This skill helps define or update SECURITY.md files that guide security scanning of repositories. It establishes system boundaries, threat models, security invariants, and reportable findings so that Codex Security understands what matters and what is out of scope for the codebase.

When to use it

  • Creating or refreshing SECURITY.md for a new repository or component
  • Clarifying what threat model or security properties a scanner should verify
  • Documenting scope exclusions, accepted risks, or severity context for findings
  • Updating policy when code architecture or deployment changes

When not to

  • Executing security fixes or remediating actual vulnerabilities
  • Analyzing or triaging existing security findings
  • Creating executable security controls or automation rules
