95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Create or verify a project's DESIGN.md and MOTION.md instead of assuming one exists. Use when a project has no design or motion contract, when a contract may have drifted from the rules it claims to follow, or when you need to know which rules are actually enforced here. Runs a generator that measures the project and a checker that refuses unanswered decisions.

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/'design-contract' ] || [ -L ~/.agents/skills/'design-contract' ]; then echo 'A skill folder named design-contract already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/rexleimo/aios' "$d" && git -C "$d" checkout --quiet '20428ee1ebde727163f5cfbdebaaf5b831e4b25c' -- 'skill-sources/design-contract' && mkdir -p ~/.agents/skills && cp -R "$d"/'skill-sources/design-contract' ~/.agents/skills/'design-contract' && 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/'design-contract' ~/.claude/skills/'design-contract' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
