Review the instructions the agent will receive before you install.

Web Application Security

Authorization

Use this skill only with explicit written authorization for a named scope (systems, environments, and time window). If authorization is missing, expired, or the request is for someone else's systems, stop.

This skill is defensive and owner-authorized. It does not authorize offensive cyber operations.

Do

  • Enforce authorization on every handler; never rely on the UI
  • Parameterize queries; reject unknown fields
  • Treat cookies, tokens, and redirects as untrusted until validated
  • Add tests for authz, CSRF, and open redirects when you change those paths

Do not

  • Provide XSS or SQLi payloads for use against systems you do not own

  • Disable CSRF or SameSite 'to make local dev easier' in production configs

  • Do not produce exploit payloads, malware, or attack procedures.

How to Use

Load this skill from /cc-security when the Task Card domain is security-web. Example prompts:

  • Review our Next.js Server Actions for IDOR and CSRF. Propose tests, not exploits.
  • Harden the file-upload endpoint: type, size, path containment, and tests.

Integration

  • Workflow: /cc-security (CCEP command security)
  • Existing OWASP application-security skill remains security (not this id)
  • High-risk changes still require security-reviewer
