Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By dreadnode/capabilities (GitHub) · security · 22 stars · scanned at commit 3ceeb34

Local vulnerability knowledge base with CWE references, attack playbooks by tech stack, and detection signatures. Use when you need vulnerability context for a specific CWE, attack strategies for a technology stack, detection signatures for static analysis, or mapping between static analysis signals and vulnerability classes.

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/'vuln-kb' ] || [ -L ~/.agents/skills/'vuln-kb' ]; then echo 'A skill folder named vuln-kb already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dreadnode/capabilities' "$d" && git -C "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/vuln-kb' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/vuln-kb' ~/.agents/skills/'vuln-kb' && 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/'vuln-kb' ~/.claude/skills/'vuln-kb' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
