Evidence-first development — surround the implementation with an executable spec and a gauntlet of constraints (tests, types, coverage, mutation) so line-by-line review becomes optional. Use when the user explicitly asks for high-assurance or evidence-first work ("reliable", "TDD", "prove it works", "I won't read the code"), or when the change touches high-stakes domains (money, auth, data loss, concurrency, public API).

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/'old-coder' ] || [ -L ~/.agents/skills/'old-coder' ]; then echo 'A skill folder named old-coder already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/AmazingAng/old-coder' "$d" && git -C "$d" checkout --quiet 'a0eb529d393a1cb3ccc564e32b2104e7e75c7a29' -- 'skills/old-coder' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/old-coder' ~/.agents/skills/'old-coder' && 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/'old-coder' ~/.claude/skills/'old-coder' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
