Resend CLI
This repository (Asymmetric-al/core)
These repo-owned sections are intentionally kept on top of the vendored Resend
CLI skill. If upstream refreshes replace this file, reconcile this overlay
before running bun run skills:sync. App-level Resend integration lives in
docs/guides/features/resend-integration.md; this skill is only for the
terminal CLI, shell scripts, and CI automation.
Triggers
Running, scripting, installing, or troubleshooting the resend CLI.
Resend CLI work in local shells, CI/CD, automations, or non-interactive agent runs.
Sending or previewing React Email templates through CLI flags.
Workflow
Confirm the task is CLI work; for product email routes, SDK, webhooks, or inbound handling, use docs/guides/features/resend-integration.md instead.
Check resend --version before invoking CLI commands.
Confirm required environment variables are available without printing secret values.
Use non-interactive flags and JSON-safe output patterns from this skill.
Verify the command result and capture sanitized IDs/status only.
Checklist
Confirmed the task belongs to Resend CLI rather than app integration.
Verified the resend binary and auth/env prerequisites.
Avoided printing API keys, tokens, or full secret values.
Used non-interactive flags suitable for agents/CI.
Recorded sanitized command evidence or a clear blocker.
Installation
Before running any resend commands, check whether the CLI is installed:
