This is the official Resend CLI packaged as a Claude skill, and it's genuinely comprehensive. You get the full platform from the terminal: send emails (including React Email .tsx templates), manage domains and DNS verification, handle broadcasts, contacts, webhooks, API keys, and logs. The skill includes detailed gotchas that matter in practice, like remembering that delete commands need an explicit --yes flag in non-interactive mode, webhook signing secrets are shown only once, and batch sends don't support scheduling. The CLI auto-detects when it's being called by an agent and switches to JSON output without prompts. Load this before running any resend commands so Claude knows the non-interactive contract and doesn't trip on silent failures.
