This skill appears to do what it says (send mail through Resend) but take these precautions before installing or running it: 1) The runtime requires RESEND_API_KEY even though the registry metadata doesn't declare it — set a dedicated API key with minimal scope and rotate it if needed. 2) The script will load and export variables from home/.openclaw/workspace/.env (if present) before falling back to local .env; if you keep other secrets there, they could be picked up unintentionally. Consider placing the API key in a dedicated env or passing it directly rather than storing many secrets in a shared .env. 3) Review the included scripts/send_email.py yourself (or run in an isolated environment) — it uses curl via subprocess to post to https://api.resend.com/emails and does not appear to exfiltrate data elsewhere, but reading arbitrary .env files increases risk. 4) If you will let agents invoke this skill autonomously, ensure the agent's permissions and the API key scope are limited. If you want, provide the developer with a request to update the registry metadata to declare RESEND_API_KEY as a required credential and to document why the home .openclaw workspace .env is consulted.

Type: OpenClaw Skill Name: resend-email-sender Version: 1.0.0 The OpenClaw skill 'resend-email-sender' is designed to send emails via the Resend API. The `SKILL.md` provides clear, functional instructions without any prompt injection attempts. The `scripts/send_email.py` script correctly implements this functionality, retrieving API keys from environment variables or `.env` files and using `subprocess.run` with a list of arguments to execute `curl`, which mitigates shell injection risks. The script communicates with the legitimate Resend API endpoint (api.resend.com) and shows no evidence of data exfiltration, persistence mechanisms, or other malicious behaviors.
