Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.
By Orizon-eu/claude-code-pentest (GitHub) · security · 31 stars · scanned at commit f1cf16f
Automated API security testing starting from domains. Discovers REST, GraphQL, and SOAP APIs, reconstructs schemas, and tests for BOLA/IDOR, BFLA, mass assignment, JWT attacks, rate limiting bypass, and business logic flaws. Use when user asks to "test API security", "break API", "find API vulnerabilities", "test GraphQL", "test JWT", "API pentest", or provides domains with API endpoints. For authorized testing only.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'api-breaker' ] || [ -L ~/.agents/skills/'api-breaker' ]; then echo 'A skill folder named api-breaker already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Orizon-eu/claude-code-pentest' "$d" && git -C "$d" checkout --quiet 'f1cf16f691fbc5d87aa6ed421a945f1af3fc7af7' -- 'api-breaker' && mkdir -p ~/.agents/skills && cp -R "$d"/'api-breaker' ~/.agents/skills/'api-breaker' && rm -rf "$d"; fi
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/'api-breaker' ~/.claude/skills/'api-breaker' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
