# Point the model at a file with `@path`

Name a file or a directory in your question with `@` followed by its path. mini-me checks that the path exists, tells the model where it is, and the model reads it with its tools. There is no picker or completion: you type the path.

## Steps

1. Start `mm` from the project directory. Relative paths are resolved from there.
2. Write the path in the question, glued to `@`:

   ```
   > explain what @internal/acp/acp.go does with @internal/session
   📎 /work/mini-me/internal/acp/acp.go
   📎 /work/mini-me/internal/session
   ```

   One `📎` line per attached path confirms the notation was understood. The model receives your sentence as typed, followed by one line per path:

   ```
   [attached file: /work/mini-me/internal/acp/acp.go]
   [attached directory: /work/mini-me/internal/session]
   ```

3. Ask away. The content is not copied into the prompt: the model runs `cat`, `read_file` or `ls` on the path when it needs to.

## Rules

| Case | Result |
|------|--------|
| `@internal/acp/acp.go` | Relative to the directory `mm` was started in (the session's `cwd` in ACP mode). |
| `@/abs/path`, `@~/file` | Absolute paths and `~` work. |
| `@main.go,` `(@main.go)` `"@main.go"` | Sentence punctuation and brackets around the mention are ignored. |
| `@bob`, `@does/not/exist` | Nothing on disk: left in the sentence as plain text, no attachment. |
| `k33g@example.com` | A `@` glued to a word is not a mention. |
| Same path twice | Attached once. |
| Path with spaces | Not supported: a mention ends at the first space. |

## In an editor (ACP)

The editor's own `@` picker sends the file as a `resource_link`, which mini-me turns into the same `[attached file: …]` line. A path typed by hand, without the picker, is understood the same way, relative to the project the editor opened. Attached paths are logged on stderr as `[acp] session <id>: attached <path>`.
