K369 closed-world tool membership check before execution. Validate tool name and optional arg keys against a local registry (skills + scripts + example schema). Use when the operator says closed-world check / validate tool name / is this tool registered. Pairs scout-tool-search and step-gate.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'closed-world-tool-check' ] || [ -L ~/.agents/skills/'closed-world-tool-check' ]; then echo 'A skill folder named closed-world-tool-check already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/cemini23/Cybersecurity-wiki' "$d" && git -C "$d" checkout --quiet '5ea7630c92d7788635bddb1c35b4f0d45e9d7e71' -- '.cursor/skills/closed-world-tool-check' && mkdir -p ~/.agents/skills && cp -R "$d"/'.cursor/skills/closed-world-tool-check' ~/.agents/skills/'closed-world-tool-check' && 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/'closed-world-tool-check' ~/.claude/skills/'closed-world-tool-check' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
