## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/teams.microsoft.com/edit_chat_message`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/teams.microsoft.com/edit_chat_message
```

## Input

- `mid` (string, required): Message id of your own message to edit, taken verbatim from get_chat_messages for this chat. Do not use the id returned by send_chat_message: it is not the id Teams stores for the message, so it cannot be found here. The id is an opaque string (older messages carry 13 digits, newer ones 19); never construct or parse it, pass through exactly what get_chat_messages returned.
- `newText` (string, required): Replacement text for the message.
- `contactName` (string, required): Display name of the person whose 1:1 chat to open, as it appears in Teams (e.g. "April Deere").

## Output

- `mid` (string, required)
- `text` (string | null, required): Text of the message read back after the edit.
- `edited` (boolean, required)
