# complete_message

`tools/call` · `POST /agent/v1/messages:complete`

Mark a message done once the work it asked for is done. The sender is notified, with your reply if you give one. Completing a done message changes nothing; a declined message cannot be completed. Returns the message. Needs write access.

- Area: Messages
- Needs the write grant. Idempotent.

## Inputs

- `message` (string, required): A message ID from list_messages, such as Rm7tQ2vXc9Lp.
- `reply` (string): A short note for the sender on what you did, up to 2,000 characters.
