Use when about to choose, configure, or refine a tool, library, config format, API pattern, or project setup, or before proposing a design or fix of your own — research current guidance, pitfalls, and prior art for the problem it solves first; already knowing an approach, or assuming no prior art exists, is not an exemption. Also use when the user asks about best practices, gotchas, or recommended patterns

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/'best-practices' ] || [ -L ~/.agents/skills/'best-practices' ]; then echo 'A skill folder named best-practices already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/vinta/hal-9000' "$d" && git -C "$d" checkout --quiet 'ada6eb5ed0de3020027c7a59e5d0aeb76889528d' -- 'skills/best-practices' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/best-practices' ~/.agents/skills/'best-practices' && 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/'best-practices' ~/.claude/skills/'best-practices' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
