Fine to try.

By ericrisco/rsc-harness (GitHub) · coding · 591 stars · scanned at commit f3765d3

Use when building or reviewing a client-side React SPA bundled by Vite (React 19.2): components, where state lives, hooks, server data fetching, client routing, re-render and effect bugs. NOT App Router / server components / SSR (that is `nextjs`); NOT native screens (that is `react-native`).

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'react' ] || [ -L ~/.agents/skills/'react' ]; then echo 'A skill folder named react already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ericrisco/rsc-harness' "$d" && git -C "$d" checkout --quiet 'f3765d35e91690c0c7e511447da6cd0176ab38e0' -- 'skills/react' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/react' ~/.agents/skills/'react' && 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/'react' ~/.claude/skills/'react' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
