### Introducing the new prompt editor

The **Prompt editor** is a new rich text editing experience for writing agent prompts. It replaces the previous plain-text editor with a structured interface where input arguments, tools, contexts, escalations, and outputs are inserted as color-coded inline references — called pills — using a single `@` trigger, rather than typed syntax like `{{argument_name}}` or different syntaxes per reference type.

The editor supports Markdown formatting with an Edit/Preview toggle, a formatting toolbar with undo and redo, and a fullscreen mode. It automatically propagates renames across all prompts, highlights invalid references in red, surfaces evaluation coverage inline, and enables AI suggestion review.

Existing prompts require no changes. The editor reads and writes the same underlying format — `{{argument}}` for inputs and `@{path}` for tools, contexts, and outputs — so existing prompts open as pills automatically. Typing `{{ }}` directly is no longer a creation trigger; use `@` to insert references going forward. 

For details, refer to [Prompt editor](../user-guide/prompt-editor.md).

### Known issues

The following known issues affect the new Prompt editor:

- Renaming a tool does not update the pill name in the prompt when using **Canvas** view. Renames are reflected only in **Form** view.
- Prompt scrolling does not work in fullscreen mode.
