## Statements (checkable)
0. Create Message: content is up to 2000 characters; up to 10 rich embeds; the combined characters of title, description, field names/values, footer text and author name across all embeds must not exceed 6000, otherwise the API responds Bad Request.  [✓0 ✗0]
1. The API reference shows error code 50035 with message "Invalid Form Body" and per-field errors; a missing or invalid Content-Type also yields 50035 ("Invalid form body").  [✓0 ✗0]

## Fix
```text
Chunk agent output into <= 2000-character messages (or attach it as a .txt file), keep embeds within 10 / 6000 characters, and send application/json or multipart/form-data with payload_json.
```

## Error signatures
- substring: `Invalid Form Body`
