What it does, in the publisher's words
Use when working with the Resend email API — sending transactional emails (single or batch), receiving inbound emails via webhooks, managing email templates, tracking delivery events, managing domains, contacts, broadcasts, webhooks, API keys, inboxes (threads, labels, drafts, replies), automations, events, viewing API request logs, checking account usage and quotas, or setting up the Resend SDK.
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 Resend
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 resend/resend-skills --skill resend
This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (resend), or copy only this skill into ~/.claude/skills. docs
/plugin marketplace add resend/resend-skills /plugin install <plugin>@resend-skills # or only this skill: npx skills add resend/resend-skills --skill resend -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/resend/resend-skills.git /tmp/resend-src cp -r /tmp/resend-src/skills/resend ./resend zip -r resend.zip resend
Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

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 resend/resend-skills resend
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

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/resend/resend-skills.git --path skills/resend
OpenCode reads .opencode/skills, ~/.config/opencode/skills and the Claude and .agents folders. docs
npx skills add resend/resend-skills --skill resend -a opencode
Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs
