 | Slug (`slug`)                            | A **unique internal identifier** for the mode. It's used by Roo Code to reference the mode, especially for associating [mode-specific instruction files](#mode-specific-instructions-via-filesdirectories).                                                                                                                                                                                                   |
 | Name (`name`)                            | The **display name** for the mode as it appears in the Roo Code user interface. This should be human-readable and descriptive.                                                                                                                                                                                                                                                                               |
 | Role Definition (`roleDefinition`)       | Defines the **core identity and expertise** of the mode. This text is placed at the beginning of the system prompt.<br />- Its primary function is to define Roo's personality and behavior when this mode is active.<br />- The **first sentence** (up to the first period `.`) serves as a default concise summary for Roo to understand the mode's general purpose. <br />- **However, if the `whenToUse` property is defined, `whenToUse` takes precedence** for summarizing the mode's function, especially in contexts like task orchestration or mode switching. In such cases, the first sentence of `roleDefinition` is less critical for this specific summarization task, though the entire `roleDefinition` is still used when the mode is active to guide its overall behavior. |
-| Available Tools (`groups`)               | Defines the **allowed toolsets and file access permissions** for the mode.<br />- In the UI, this corresponds to selecting which general categories of tools (like reading files, editing files, browsing, or executing commands) the mode can use.<br />- File type restrictions for the "edit" group are typically managed via manual YAML/JSON configuration or by asking Roo to set them up, as detailed in the [Property Details for `groups`](#groups-1). |

 | When to Use (optional) (`whenToUse`)     | (Optional) Provides **guidance for Roo to understand the mode's purpose**, especially for automated decisions.<br />- This text is used by Roo, particularly the [`🪃 Orchestrator`](/basic-usage/using-modes#orchestrator-mode-aka-boomerang-mode) mode, for [orchestrating tasks](/features/boomerang-tasks) (e.g., via the [`new_task`](/advanced-usage/available-tools/new-task) tool).<br />- It also helps Roo decide which mode is appropriate when [switching modes](/basic-usage/using-modes#switching-between-modes) (e.g., via the [`switch_mode`](/advanced-usage/available-tools/switch-mode) tool).<br />- If populated, this description is used by Roo to understand the mode's function; otherwise, the first sentence of the `roleDefinition` is used by default. |
 | Custom Instructions (optional) (`customInstructions`) | **Specific behavioral guidelines** or rules for the mode.<br />- These instructions are added near the end of the system prompt to further refine Roo's behavior beyond the `roleDefinition`.<br />- This can be provided directly in the configuration or via separate instruction files.                                                                                                                               |
