# Notifications (experimental)
Gemini CLI can send system notifications to alert you when a session completes
or when it needs your attention, such as when it's waiting for you to approve a
tool call.
> **Note:** This is a preview feature currently under active development.
> Preview features may be available on the **Preview** channel or may need to be
> enabled under `/settings`.
Notifications are particularly useful when running long-running tasks or using
[Plan Mode](./plan-mode.md), letting you switch to other windows while Gemini
CLI works in the background.
## Requirements
Currently, system notifications are only supported on macOS.
### Terminal support
The CLI uses the OSC 9 terminal escape sequence to trigger system notifications.
This is supported by several modern terminal emulators. If your terminal does
not support OSC 9 notifications, Gemini CLI falls back to a system alert sound
to get your attention.
## Enable notifications
Notifications are disabled by default. You can enable them using the `/settings`
command or by updating your `settings.json` file.
1. Open the settings dialog by typing `/settings` in an interactive session.
2. Navigate to the **General** category.
3. Toggle the **Enable Notifications** setting to **On**.
Alternatively, add the following to your `settings.json`:
```json
{
"general": {
"enableNotifications": true
}
}
```
## Types of notifications
Gemini CLI sends notifications for the following events:
- **Action required:** Triggered when the model is waiting for user input or
tool approval. This helps you know when the CLI has paused and needs you to
intervene.
- **Session complete:** Triggered when a session finishes successfully. This is
useful for tracking the completion of automated tasks.
## Next steps
- Start planning with [Plan Mode](./plan-mode.md).
- Configure your experience with other [settings](./settings.md).

## Planning workflows
Plan Mode provides building blocks for structured research and design. These are
implemented as [extensions](../extensions/index.md) using core planning tools
like [`enter_plan_mode`](../tools/planning.md#1-enter_plan_mode-enterplanmode),
[`exit_plan_mode`](../tools/planning.md#2-exit_plan_mode-exitplanmode), and
[`ask_user`](../tools/ask-user.md).
### Built-in planning workflow
The built-in planner uses an adaptive workflow to analyze your project, consult
you on trade-offs via [`ask_user`](../tools/ask-user.md), and draft a plan for
your approval.
### Custom planning workflows
You can install or create specialized planners to suit your workflow.
#### Conductor
[Conductor] is designed for spec-driven development. It organizes work into
"tracks" and stores persistent artifacts in your project's `conductor/`
directory:
- **Automate transitions:** Switches to read-only mode via
[`enter_plan_mode`](../tools/planning.md#1-enter_plan_mode-enterplanmode).
- **Streamline decisions:** Uses [`ask_user`](../tools/ask-user.md) for
architectural choices.
- **Maintain project context:** Stores artifacts in the project directory using
[custom plan directory and policies](#custom-plan-directory-and-policies).
- **Handoff execution:** Transitions to implementation via
[`exit_plan_mode`](../tools/planning.md#2-exit_plan_mode-exitplanmode).
#### Build your own
Since Plan Mode is built on modular building blocks, you can develop your own
custom planning workflow as an [extensions](../extensions/index.md). By
leveraging core tools and [custom policies](#custom-policies), you can define
how Gemini CLI researches and stores plans for your specific domain.
To build a custom planning workflow, you can use:
- **Tool usage:** Use core tools like
[`enter_plan_mode`](../tools/planning.md#1-enter_plan_mode-enterplanmode),
[`ask_user`](../tools/ask-user.md), and
[`exit_plan_mode`](../tools/planning.md#2-exit_plan_mode-exitplanmode) to
manage the research and design process.
- **Customization:** Set your own storage locations and policy rules using
[custom plan directories](#custom-plan-directory-and-policies) and
[custom policies](#custom-policies).
> **Note:** Use [Conductor] as a reference when building your own custom
> planning workflow.
By using Plan Mode as its execution environment, your custom methodology can
enforce read-only safety during the design phase while benefiting from
high-reasoning model routing.
