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 Cloudflare Agents SDK

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 cloudflare/skills --skill agents-sdk

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (cloudflare), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add cloudflare/skills
/plugin install <plugin>@cloudflare

# or only this skill:
npx skills add cloudflare/skills --skill agents-sdk -a claude-code

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/cloudflare/skills.git /tmp/agents-sdk-src
cp -r /tmp/agents-sdk-src/skills/agents-sdk ./agents-sdk

npx skills add cloudflare/skills --skill agents-sdk -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 cloudflare/skills agents-sdk

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 cloudflare/skills --skill agents-sdk -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/cloudflare/skills.git --path skills/agents-sdk

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

npx skills add cloudflare/skills --skill agents-sdk -a opencode

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