File & image attachments

Attaching files

Type @ anywhere in your message to attach files as context:

> explain @src/auth.rs
> compare @old_impl.rs and @new_impl.rs
> what's wrong with @error.log

As you type after @, a fuzzy file picker appears. Press Tab to cycle through matches or select with Enter. The file’s full contents are injected into the message before it’s sent to the model.

Images

For vision-capable models (Claude, Gemini, GPT-4o), attach images directly:

> what does @screenshot.png show?
> explain the architecture in @diagram.png

Supported formats: PNG, JPEG, GIF, WEBP. Images are base64-encoded and sent inline to the model API.

Non-image files (SVG, PDF, etc.) attached via @ are sent as text content, not as vision input.

Large pastes

Pasting more than ~500 characters into the input is automatically wrapped in a reference block to keep prompts clean:

> [pasted 1,234 chars — attached as reference]
> what's the bug in this code?

The paste is still sent to the model; it just doesn’t clutter the display.
