How to save an answer to a file

This guide shows how to keep an answer of the agent — a mini tutorial, an explanation, a snippet — in a Markdown file, without the model writing it a second time. It assumes you use mm in the terminal or the window mode (-tui).

There are two ways. /save is a command you type: nothing is asked of the model. save_answer is a tool the model calls when you ask in your own words.

Save with the command

Ask your question and wait for the answer.

Type:

/save nushell-first-script.md

mm writes the last answer as it is and prints:

💾 saved the last answer to nushell-first-script.md (2418 bytes)

To save an earlier answer, add its rank from the end: /save rust-app.md 2 saves the answer before the last one.

Save by asking the agent

Turn the tool on in the agent file:
```
saveAnswerTool: true
```

Ask in your own words, after the answer or in the same request:

save it in nushell-first-script.md

teach me pattern matching in Kotlin and save it in kotlin-match.md

The model only sends the file name; mm writes the text the model already gave. The terminal shows:

💾 save_answer: nushell-first-script.md (the previous answer)

Variants

The file already exists. Neither /save nor save_answer overwrites it: they say so and write nothing. Give another name, or remove the file first.
A directory that does not exist yet. /save notes/rust/app.md creates notes/rust/.
You want each save confirmed. With yolo: false, save_answer asks before writing, like write_file. /save never asks: you typed it.
In an editor (ACP). /save is not offered there; save_answer works, and writes in the session's directory.

# How to save an answer to a file

This guide shows how to keep an answer of the agent — a mini tutorial, an explanation, a snippet — in a Markdown file, without the model writing it a second time. It assumes you use mm in the terminal or the window mode (`-tui`).

There are two ways. `/save` is a command you type: nothing is asked of the model. `save_answer` is a tool the model calls when you ask in your own words.

## Save with the command

1. Ask your question and wait for the answer.

2. Type:

   ```
   /save nushell-first-script.md
   ```

   mm writes the last answer as it is and prints:

   ```
   💾 saved the last answer to nushell-first-script.md (2418 bytes)
   ```

3. To save an earlier answer, add its rank from the end: `/save rust-app.md 2` saves the answer before the last one.

## Save by asking the agent

1. Turn the tool on in the agent file:

   ```yaml
   saveAnswerTool: true
   ```

2. Ask in your own words, after the answer or in the same request:

   ```
   save it in nushell-first-script.md
   ```

   ```
   teach me pattern matching in Kotlin and save it in kotlin-match.md
   ```

   The model only sends the file name; mm writes the text the model already gave. The terminal shows:

   ```
   💾 save_answer: nushell-first-script.md (the previous answer)
   ```

## Variants

- **The file already exists.** Neither `/save` nor `save_answer` overwrites it: they say so and write nothing. Give another name, or remove the file first.
- **A directory that does not exist yet.** `/save notes/rust/app.md` creates `notes/rust/`.
- **You want each save confirmed.** With `yolo: false`, `save_answer` asks before writing, like `write_file`. `/save` never asks: you typed it.
- **In an editor (ACP).** `/save` is not offered there; `save_answer` works, and writes in the session's directory.
