+# VoiceAgent Architecture & Developer Guide (AGENTS.md)
+
+This document contains architectural guidelines, operational patterns, and learnings for AI agents and developers working on the `VoiceAgent` codebase.
+
+---
+
+## 1. Project Overview & Architecture
+
+`VoiceAgent` is a high-performance, real-time voice conversation system built on Pipecat and optimized for macOS.
+
+- **Audio Pipeline**:
+  - **Sample Rates**: STT / VAD operates natively at **16 kHz**; Kokoro TTS synthesizes at **24 kHz**.
+  - **VAD / Push-to-Talk**: Silero VAD (`SileroVADAnalyzer`) and Push-To-Talk (`push_to_talk.py`, `global_hotkey.py`).
+  - **STT**: Apple `SpeechAnalyzer` (macOS 26+) or Whisper MLX / CPU (`speech_analyzer_stt.py`, `apple_stt.py`).
+  - **TTS**: Kokoro Neural TTS (`KokoroTTSService`) or macOS System Speech (`apple_tts.py`).
+- **LLM Slot**:
+  - Primary Harness: **Hermes** (`hermes_llm.py` / `HermesLLM`).
+  - Additional Engines: Claude Code (`claude_llm.py`), local macOS MLX (`apple_llm.py`).
+
+---
+
+## 2. Hermes Integration & Session Handling
+
+- **CLI Subcommand & Mode**:
+  - Uses `hermes chat -q "<query>" -Q --source voice`.
+  - The `-Q` (quiet mode) flag suppresses decorative headers, spinners, and preview output so only cleaned text reaches TTS.
+- **Stderr Session Tracking**:
+  - Hermes outputs session headers (e.g. `session_id: 20260809_...`) on **`stderr`**.
+  - `_remember_session_id()` in `hermes_llm.py` extracts the session ID from stderr and persists it.
+- **Per-Workspace Session Persistence**:
+  - Session state is saved per workspace in `.hermes-voice-session.json` (inside `cwd`), keeping project histories isolated.
+  - On restart, `HermesLLM` loads the active session ID and resumes with `hermes chat ... -r <session_id>`.
+- **Display Renaming**:
+  - Automatically renames the active session to `"Voice Agent"` via `hermes sessions rename <session_id> "Voice Agent"` on the first turn.
+- **Native Persona & Memory**:
+  - Hermes manages persona, preferences, and long-term memory natively in `~/.hermes`.
+  - Avoid injecting redundant system prompt wrappers (`Brain` memories or `AGENTS.md` personality prompts) into Hermes turns.
+- **Model Selection**:
+  - Default model setting is `"default"`, letting Hermes use its configured model in `~/.hermes/config.yaml`. Avoid passing `-m` unless explicitly overriding the model.
+
+---
+
+## 3. App Directory Storage (No `~/Workspace` Dependency)
+
+The project operates entirely from the app directory without depending on `~/Workspace`:
+
+- **Vocabulary & Repairs**: `vocabulary.txt` and `corrections.txt` live directly in the app root folder.
+- **App Settings**: `model_settings.json`, `voice_settings.json`, and `journal.jsonl` are saved in the app folder.
+- **CLI Helper Scripts**:
+  - `bin/voice_tool.py`: List and switch TTS voices (`python bin/voice_tool.py list`, `python bin/voice_tool.py set <voice>`).
+  - `bin/model_tool.py`: List and switch LLM models (`python bin/model_tool.py list`, `python bin/model_tool.py set <model>`).
+  - `bin/session_tool.py`: Inspect or reset active Hermes session (`python bin/session_tool.py get`, `python bin/session_tool.py reset`).
+  - `bin/profile_tool.py`: List and switch Hermes agent profiles (`python bin/profile_tool.py list`, `python bin/profile_tool.py set <profile>`).
+  - `bin/web_tool.py`: Inspect files or URLs in the Companion Web UI drawer (`http://localhost:8888`).
+
+---
+
+## 4. Building & Packaging `/Applications/VoiceAgent.app`
+
+`VoiceAgentLauncher` runs Python scripts dynamically from the project workspace (configured in `~/.voiceagent.env` or `VOICEAGENT_DIR`). 
+
+- **Python code edits take effect immediately** without recompiling or re-signing the macOS app bundle.
+- **Rebuilding binaries** (`bash build_app.sh`) is only required when modifying Swift sources (`swift/*.swift`), helper binaries, or `Info.plist` entitlements.
+- `build_app.sh` automatically updates `~/.voiceagent.env` and skips binary re-signing if Swift sources are unchanged, preserving macOS privacy permissions (Microphone, Accessibility, Speech Recognition). Use `bash build_app.sh -f` to force a full rebuild.
+
+```bash
+bash build_app.sh
+```
+
+**Build Workflow**:
+1. Configures `~/.voiceagent.env` with `VOICEAGENT_DIR` and `VOICEAGENT_PYTHON`.
+2. Checks if Swift binaries (`speech-helper`, `llm-helper`, `VoiceAgentLauncher`) need recompiling.
+3. If up to date, copies Python resources without re-signing the app bundle (preserving macOS TCC permissions).
+4. If modified, compiles Swift binaries, creates `dist/VoiceAgent.app`, signs, and installs to `/Applications/VoiceAgent.app`.
+
+---
+
+## 5. Verification & Testing

+# Packaging Python Applications into Native macOS Apps (`.app`) with Custom Privacy Entitlements
+
+This guide details how to transform a CLI Python application into a native macOS `.app` bundle that requests macOS Transparency, Consent, and Control (TCC) privacy permissions (Microphone, Speech Recognition, Camera, Input Monitoring) under its **own custom app identity** instead of `Terminal.app` or `python3.11`.
+
+---
+
+## 1. Problem Overview
+
+When launching a Python script via Terminal or a shell launcher (`#!/bin/bash`), macOS TCC attributes privacy permissions to either:
+1. `Terminal.app` (if executed inside a terminal window), or
+2. `python3.11` / `python3.1` (if `exec /path/to/python` is called from a script).
+
+To ensure macOS prompts display your custom application name (e.g., *"VoiceAgent would like to access the microphone"*) and show up under **System Settings → Privacy & Security → Microphone**, you must follow Apple's native bundle layout and executable architecture.
+
+---
+
+## 2. Key Architectural Requirements
+
+```
+VoiceAgent.app/
+└── Contents/
+    ├── Info.plist               # App Identity & Custom Privacy Descriptions
+    ├── MacOS/
+    │   └── VoiceAgent           # Compiled Mach-O Swift Launcher Binary
+    └── Resources/
+        ├── src/                 # Packaged Python Source Code
+        └── swift/               # Native Helper Binaries (speech-helper, llm-helper)
+```
+
+1. **Standard macOS `.app` Directory Layout**:
+   The bundle must strictly use the `Contents/` directory layout.
+
+2. **Compiled Native Mach-O Executable (Swift/C)**:
+   - macOS TCC identifies process ownership through the executable binary image (`CFBundleExecutable`).
+   - Shell scripts (`/bin/bash`) cause macOS to inspect the underlying `python` image and attribute permissions to `python3.1`.
+   - **Solution**: Compile a native Swift executable (`swift/VoiceAgentLauncher.swift`) into a Mach-O 64-bit arm64 binary (`Contents/MacOS/VoiceAgent`). When Finder launches this binary, macOS registers the process under `com.voiceagent.mac`. Subprocesses spawned by this binary inherit the bundle's TCC identity.
+
+3. **Privacy Entitlements in `Info.plist` & Code Signing**:
+   - `Info.plist` defines `CFBundleExecutable`, `CFBundleIdentifier`, and the `NS*UsageDescription` keys.
+   - The app bundle must be deeply code-signed (`codesign --deep`).
+
+---
+
+## 3. Implementation Workflow
+
+### Step 1: Native Swift Launcher (`swift/VoiceAgentLauncher.swift`)
+
+The Swift launcher sets environment variables, redirects logs, and spawns the Python process:
+
+```swift
+import Foundation
+
+@main
+struct VoiceAgentLauncher {
+    static func main() {
+        let fileManager = FileManager.default
+        let projDir = "/Users/adolforeyna/Projects/VoiceAgent1"
+        
+        let bundleResPath = Bundle.main.resourcePath ?? ""
+        let bundledSrcPath = "\(bundleResPath)/src"
+        
+        let workDir = fileManager.fileExists(atPath: projDir) ? projDir : bundledSrcPath
+        let pythonBin = "\(projDir)/.venv/bin/python"
+        let fallbackPython = "/usr/bin/python3"
+        let targetPython = fileManager.fileExists(atPath: pythonBin) ? pythonBin : fallbackPython
+        let targetScript = "\(workDir)/app_main.py"
+
+        setenv("SSL_CERT_FILE", "/etc/ssl/cert.pem", 1)
+        setenv("REQUESTS_CA_BUNDLE", "/etc/ssl/cert.pem", 1)
+
+        let logDir = fileManager.homeDirectoryForCurrentUser.appendingPathComponent("Library/Logs/VoiceAgent")
+        try? fileManager.createDirectory(at: logDir, withIntermediateDirectories: true)
+        let logFile = logDir.appendingPathComponent("voiceagent.log")
+
+        if !fileManager.fileExists(atPath: logFile.path) {
+            fileManager.createFile(atPath: logFile.path, contents: nil)
+        }
+
+        let process = Process()
+        process.executableURL = URL(fileURLWithPath: targetPython)
+        process.arguments = [targetScript]
+        process.currentDirectoryURL = URL(fileURLWithPath: workDir)
+
+        if let logHandle = try? FileHandle(forWritingTo: logFile) {
+            logHandle.seekToEndOfFile()
+            process.standardOutput = logHandle
+            process.standardError = logHandle
+        }
+
+        do {
+            try process.run()
+            process.waitUntilExit()
+        } catch {
+            print("Failed to run VoiceAgent: \(error)")
+        }
+    }
+}
+```
+
+---
+
+### Step 2: Build & Package Script (`build_app.sh`)
+
+Automate Swift binary compilation, bundle structure creation, `Info.plist` injection, installation to `/Applications`, and code signing:
+
+```bash
+#!/bin/bash
+set -euo pipefail

+## macOS AirPods route switching checklist
+
+When no audio device is pinned, VoiceAgent follows macOS's current default
+microphone and speaker while a conversation is running. Use this checklist when
+validating AirPods or another Bluetooth headset:
+
+1. Connect AirPods before starting `./talk`; confirm that both microphone and
+   speaker audio use them.
+2. Start a conversation on the built-in microphone and speakers, then connect
+   AirPods. Confirm that each available direction moves independently to the
+   new macOS default without ending the conversation.
+3. Disconnect AirPods during a conversation. Confirm that the available input
+   and output return to the macOS defaults and that the conversation remains
+   usable.
+4. In Control Center or Sound settings, explicitly switch back to the built-in
+   microphone and speakers while AirPods remain connected. Confirm both routes
+   follow those defaults.
+5. Repeat connect, disconnect, and manual default changes several times to
+   catch delayed Bluetooth profile changes or a stale route listener.
+
+Run this validation without `--input-device` or `--output-device`: omitted
+values intentionally follow macOS defaults. Supplying either flag pins only that
+direction (for example, a pinned USB microphone still allows an unpinned output
+to follow AirPods); pinning both directions disables automatic route following.
+Use `./talk --list-devices` to identify a device by index or name substring.
+
+This behavior depends on macOS Core Audio notifications and the device profile
+currently exposed by Bluetooth. A headset may briefly expose only output, or
+reject the negotiated sample rate while switching profiles; VoiceAgent keeps the
+previous working route when a replacement cannot open. The terminal/app still
+needs macOS Microphone permission, and the global hold-key needs Input
+Monitoring. A sandboxed packaged app also needs the appropriate microphone usage
+description and audio-input entitlement; those platform permissions cannot be
+granted by route switching code.
+

-- Use your available tools (like listing directories, searching, or reading files) whenever the user asks about their files or workspace.
+- Use your available tools (listing directories, searching, reading files, shell execution) whenever the user asks about files, commands, CLI tools (such as Paseo), or workspace tasks.
+- You can dynamically change your spoken voice mid-response! Use markdown tags like `[Voice:af_bella]` or `[Voice:am_michael]` inline to switch voices (e.g. `[Voice:af_bella] Hello from Bella! [Voice:am_michael] And hello from Michael!`). The active voice will persist until you change it again.
+- You can change your default voice! If the user asks to list available voices or switch voice permanently, run `python bin/voice_tool.py list` or `python bin/voice_tool.py set <voice_name>` (voices: af_heart, af_bella, am_michael, am_fenrir, am_puck, bf_emma, bm_george, Moira, Daniel).
+- You can change your AI model on the fly! If the user asks to list available models or change model, run `python bin/model_tool.py list` or `python bin/model_tool.py set <model_name>` (models: luna, gemma, deepseek, gpt-oss, sonnet, etc.).
+- You can reset or start a fresh conversation session! If the user asks to start a fresh session, reset the conversation, or clear session context, run `python bin/session_tool.py reset`.
+- You can switch Hermes agent profiles! If the user asks to list Hermes profiles or switch profile, run `python bin/profile_tool.py list` or `python bin/profile_tool.py set <profile_name>`.
+- You can change the running microphone and speakers independently. For requests such as “use AirPods”, “switch to Mac speakers”, or “use the Mac default mic”, run `python bin/audio_tool.py list` then `python bin/audio_tool.py set input|output <device-name-or-index|default>`. Report the command result plainly; do not claim a device changed if the tool says it is unavailable.
+- You can open files visually for the user in the Companion Web UI drawer! Run `python bin/web_tool.py show <filepath>`.
+- You can open links or the Companion Web UI in the default browser! Run `python bin/web_tool.py open <url>`.
+- Keep implementation details and tool activity silent in the spoken channel. The user can see technical progress in the logs or Companion Web UI; only speak the useful conversational response.
+- Complete multi-step tool calls fully before speaking your final response summary.
 - Be strictly truthful about your findings and never invent fake file contents.
 - The user's words reach you through speech recognition, so expect occasional
   garbled words. Ask rather than guess when it matters.
