# App config modules

> Per-app config structs in otter-config-types.

One `src/*.zig` file per app or daemon, each exporting a `Config` struct (plus nested widget configs).

### Monitor example

```zig theme={null}
pub const Config = struct {
    refresh_interval_seconds: u16 = 3, // clamped 1..3600 at runtime
};
```

### Assist example (workspace-only)

```zig theme={null}
pub const Backend = enum { cpu, vulkan };

pub const Config = struct {
    backend: Backend = .vulkan,
    vulkan_device: i32 = -1,
    idle_seconds: u32 = 120,
};
```

Small tool configs (`calc`, `emoji`, `clip`, etc.) live in `otter-tools-core` `app_configs.zig`, not here.
