# Commands index

> **Where you are:** [Architecture map](../../README.md) → [Tauri runtime](../README.md) → Commands

**Plain English summary.** This is the registry of every Tauri command file. Each `.rs` file under `src-tauri/src/commands/` either declares one or more `#[tauri::command]` functions invoked from the frontend, or is a utility (state, security, power) that the command files share. The full list of commands actually exposed to the frontend is registered via the `tauri::generate_handler!` macro in `src-tauri/src/lib.rs:321`.

## At a glance

- Path: `src-tauri/src/commands/`.
- 22 command modules (declare `#[tauri::command]`s) plus 3 utility modules (`mod.rs`, `power.rs`, `security.rs`).
- 71 `#[tauri::command]` functions registered in `lib.rs`. A handful of additional `#[tauri::command]` functions exist in source but are NOT registered (notably the small `clipboard::copy_to_clipboard` IS registered; nothing meaningful is unregistered as of last verification).
- Total LOC across `commands/`: 6,939 (Rust source, excluding tests folder).

## Per-command page assignments

- Big files have their own page: [audio](audio.md), [live](live.md), [paste](paste.md), [models](models.md), [diagnostics](diagnostics.md), [llm](llm.md), [tts](tts.md), [transcription](transcription.md), [tasks](tasks.md), [transcripts](transcripts.md), [intentions](intentions.md), [profiles](profiles.md), [windows](windows.md), [hotkey](hotkey.md), [feedback](feedback.md).
- Utilities collapsed into one page: [Power assertions and security](power-and-security.md) covers `power.rs` and `security.rs`.
- Small modules grouped: [Small commands](small-commands.md) covers `clipboard.rs`, `fs.rs`, `hardware.rs`, `meeting.rs`, `nudges.rs`, `rituals.rs`, `update.rs`.
- Module entry: [mod.md](mod.md) covers `mod.rs` (re-exports + `build_initial_prompt` helper).

## How to navigate

- Looking for a frontend `invoke('foo', ...)` call? Search for `pub async fn foo` or `pub fn foo` under `commands/`. The page for that file lists all its commands with arg + return signatures.
- Looking for an event the frontend listens for? See the slice README's "events emitted" section, or grep for the event name across `commands/`.
- Looking for ACL gotchas? Pages flag the commands that include an `ensure_main_window` guard.
