ResendCLI

A Claude Code skill that gives Claude direct access to the Resend CLI for managing email infrastructure.

What it does

When this skill is active, Claude can use the Resend CLI to:

• Send and manage transactional emails
• Check domain verification status and DNS records
• Run diagnostics (resend doctor) and health checks
• Manage API keys, contacts, segments, and broadcasts
• Create and publish email templates
• Configure webhooks for real-time event notifications
• Manage CLI authentication profiles

The skill enforces safety guardrails — Claude will always confirm with you before sending emails, deleting resources, or performing other destructive actions.

Installation

From the standalone repo

git clone https://github.com/DomumDigital/ResendCLI.git ~/.claude/skills/ResendCLI

From the resend-cli repo (if bundled)

If this skill is included in the resend-cli repo under skills/:

# Clone the resend-cli repo
git clone https://github.com/resend/resend-cli.git

# Copy the skill into your Claude Code skills directory
cp -r resend-cli/skills ~/.claude/skills/ResendCLI

Prerequisites

• Claude Code installed
• Resend CLI installed (npm install -g resend)
• A Resend API key — either:
  • Set RESEND_API_KEY in your project's .env.local or .env file, or
  • Log in via resend login to save a CLI profile

How it triggers

The skill activates automatically when you mention anything related to Resend or email infrastructure — sending emails, checking domain status, managing contacts, troubleshooting delivery issues, reviewing webhooks, and more. Even casual prompts like "check our emails" or "how's our email setup" will trigger it.
