This skill enables Claude to validate Cross-Origin Resource Sharing (CORS) policies. It uses the cors-policy-validator plugin to analyze CORS configurations and identify potential security vulnerabilities. Use this skill when the user requests to "validate CORS policy", "check CORS configuration", "analyze CORS headers", or asks about "CORS security". It helps ensure that CORS policies are correctly implemented, preventing unauthorized cross-origin requests and protecting sensitive data.

Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'validating-cors-policies' ~/.claude/skills/'validating-cors-policies' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
