Fine to try.

Extension UI hooks and effects: when not to use `useEffect`, dependency arrays, why `JSON.stringify` deps are never the fix, cascading effects, `AbortController` cleanup. Use when an effect loops or fires every render, deps are stringified to force equality, or state lands after unmount. Rendering goes to `perf-rendering`.

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/'perf-hooks-effects' ] || [ -L ~/.agents/skills/'perf-hooks-effects' ]; then echo 'A skill folder named perf-hooks-effects already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jiayaoqijia/cryptoskill' "$d" && git -C "$d" checkout --quiet '0dc9f60ab1f3fcae24da49c4cef09c46c589f903' -- 'skills/wallets/metamask-official-perf-hooks-effects' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/wallets/metamask-official-perf-hooks-effects' ~/.agents/skills/'perf-hooks-effects' && 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/'perf-hooks-effects' ~/.claude/skills/'perf-hooks-effects' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
