+### Hotword Commands (LLM Routing)
+Instruct the LLM in `PromptBuilder` to output a specific JSON structure if given a command phrase. If a specific hotword like "System command" or "Computer dictate" is detected at the start of the audio, Toak parses the JSON, skips typng out via `xdotool`/`wtype`, and instead executes a pre-defined background action. 
+
+If it doesn't hear a command phrase, it simply returns the text normally and types it.
+
+**How it works (Under the Hood):**
+The LLM is prompted to always return JSON in the background when a command is directed at the assistant.
+```json
+{
+  "is_command": true,
+  "action": "append_to_notes",
+  "content": "Buy milk and eggs",
+  "meta": {}
+}
+```
+
+**Alternative Hotword Ideas:**
+Since "Toak" is not a real English word, Whisper might transcribe it as "talk", "toke", or "oak." It is highly recommended to use distinct, phonetically clear hotwords such as:
+- **"System..."** (e.g. "System note:")
+- **"Computer..."** (e.g. "Computer search:")
+- **"Action..."** (e.g. "Action commit:")
+- **"Dictate..."** (e.g. "Dictate terminal:")
+- **"Listen up..."** (e.g. "Listen up translate...")
+
+**Prompt Ideas & Use Cases:**
+
+1. **Quick Notes / Brainstorming:**
+   - *Hotword:* `"System note:"` or `"Drop this in my notes:"`
+   - *Action:* Appends the spoken text to a configured `~/notes.md` file in the background without interrupting your current window.
+   - *Example:* "System note: I need to remember to check the database migrations later today."
+
+2. **Terminal / CLI Execution:**
+   - *Hotword:* `"Computer terminal:"` or `"Command:"`
+   - *Action:* Takes the natural language command, asks the LLM to translate it into a bash command, and types it into a new tmux window or background process.
+   - *Example:* "Computer terminal: find all python files modified in the last 2 days."
+
+3. **Git Commit Messages:**
+   - *Hotword:* `"Action commit:"`
+   - *Action:* Automatically formats the dictated text into a standard conventional commit message, stages all files, and commits them.
+   - *Example:* "Action commit: I refactored the audio recorder to use native processes instead of the old library." -> LLM outputs `refactor(audio): migrate to native processes` and runs `git commit -am "..."`.
+
+4. **Web Search / Lookup:**
+   - *Hotword:* `"System search:"` or `"Look up:"`
+   - *Action:* Opens your default browser and performs a search for the spoken phrase.
+   - *Example:* "System search: MDN documentation for grid layout."
+
+5. **Translating on the fly:**
+   - *Hotword:* `"Translate to Spanish:"`
+   - *Action:* Instead of typing English, it types the translated version of the rest of the sentence.
+   - *Example:* "Translate to Spanish: Hello, how are you today?" -> Types out `Hola, ¿cómo estás hoy?`.
