What it does, in the publisher's words

Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.

The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install React Composition Patterns

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns

Copy the skill folder into ~/.claude/skills (all projects) or .claude/skills (this repo). Claude Code picks it up without a restart. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns -a claude-code

# or by hand:
git clone --depth 1 https://github.com/vercel-labs/agent-skills.git /tmp/composition-patterns-src
cp -r /tmp/composition-patterns-src/skills/composition-patterns ~/.claude/skills/vercel-composition-patterns

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs

git clone --depth 1 https://github.com/vercel-labs/agent-skills.git /tmp/composition-patterns-src
cp -r /tmp/composition-patterns-src/skills/composition-patterns ./vercel-composition-patterns
zip -r vercel-composition-patterns.zip vercel-composition-patterns

Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns -a codex

gh skill (GitHub CLI 2.90+, preview) installs it for Copilot in VS Code, the CLI and the cloud agent. Copilot also reads .github/skills and ~/.copilot/skills. docs

gh skill install vercel-labs/agent-skills vercel-composition-patterns

Cursor reads .cursor/skills, .agents/skills and ~/.cursor/skills (and .claude/skills). It does not install loose skills from a GitHub URL, so copy it in. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns -a cursor

Installs from the GitHub repo; --path picks this skill out of the repo. Default scope is user (all projects). docs

gemini skills install https://github.com/vercel-labs/agent-skills.git --path skills/composition-patterns

OpenCode reads .opencode/skills, ~/.config/opencode/skills and the Claude and .agents folders. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns -a opencode

Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs

npx skills add vercel-labs/agent-skills --skill vercel-composition-patterns -a windsurf

Works with

Claude Code, Claude.ai and Claude Desktop, Codex, GitHub Copilot, Cursor, Gemini CLI, OpenCode, Windsurf and other agents that read the open Agent Skills format.
