# recoup-platform-email-helper

Sends mail through the Recoup API from a Node script: the body gets serialized properly, and an empty body stops the send instead of going out.

## What it does

Reach for this skill when a task calls for mailing a report, summary or notification to the account owner or another recipient. It ships one Node script, `scripts/send-email.mjs`, which handles body serialization on its own. Building the JSON by hand with `curl` and inline `jq` is the fragile path: bad quoting lets a footer-only message titled “Message from Recoup” go out while the API still answers `success:true`. The script drops shell serialization entirely.

Writing the body to a file is the safer route, especially for HTML, since escaping stops being a concern. The script takes `--subject`, `--html-file` or `--html`, `--text-file` or `--text`, `--to`, `--cc` and `--chat-id`. With `--dry-run` it validates the payload and prints it without sending, which works as a preview. Leave `--to` out and the message goes to the account's own address.

A body is mandatory and there must be exactly one: with no non-empty `--html` or `--text` the script exits with code 2 and sends nothing. A non-zero code means the mail did not leave — read stderr and fix it rather than reporting success. Credentials come from the environment as `RECOUP_API_KEY` or `RECOUP_ACCESS_TOKEN` plus `RECOUP_API_BASE`; never print them. Node only, no dependencies, and `python3` is not guaranteed in the sandbox.
