Fine to try.

Design or audit a tool's trust boundary: keep API keys and tenant ids out of model-visible parameters, resist prompt injection, enforce permissions and approval gates in code, declare scopes, and log calls safely.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'tool-design-security' ] || [ -L ~/.agents/skills/'tool-design-security' ]; then echo 'A skill folder named tool-design-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/runtypelabs/skills/skills/tool-design-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/runtypelabs/skills/skills/tool-design-security' ~/.agents/skills/'tool-design-security' && 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/'tool-design-security' ~/.claude/skills/'tool-design-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
