Fine to try.

Design and validate model-facing tool definitions with clear names, action-oriented descriptions, bounded JSON Schema parameters, explicit side effects, safe defaults, idempotency, errors, and realistic tests. Use when creating function-calling tools, MCP tools, agent actions, structured tool inputs, or when a model selects the wrong tool, invents arguments, or causes unsafe side effects.

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-schema-design' ] || [ -L ~/.agents/skills/'tool-schema-design' ]; then echo 'A skill folder named tool-schema-design already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/seb1n/awesome-ai-agent-skills' "$d" && git -C "$d" checkout --quiet '75865a5d037a4cdaa7f409a4ec14ab9b0292920b' -- 'agent-engineering/tool-schema-design' && mkdir -p ~/.agents/skills && cp -R "$d"/'agent-engineering/tool-schema-design' ~/.agents/skills/'tool-schema-design' && 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-schema-design' ~/.claude/skills/'tool-schema-design' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
