Add Text-to-Speech Integration via TTS_INJECTION System (#934)

* feat: Add provider-agnostic TTS integration via injection point system

Implements comprehensive Text-to-Speech integration for BMAD agents using a generic
TTS_INJECTION marker system. When AgentVibes (or any compatible TTS provider) is
installed, all BMAD agents can speak their responses with unique AI voices.

## Key Features

**Provider-Agnostic Architecture**
- Uses generic `TTS_INJECTION` markers instead of vendor-specific naming
- Future-proof for multiple TTS providers beyond AgentVibes
- Clean separation - BMAD stays TTS-agnostic, providers handle injection

**Installation Flow**
- BMAD → AgentVibes: TTS instructions injected when AgentVibes detects existing BMAD installation
- AgentVibes → BMAD: TTS instructions injected during BMAD installation when AgentVibes detected
- User must manually create voice assignment file when AgentVibes installs first (documented limitation)

**Party Mode Voice Support**
- Each agent speaks with unique assigned voice in multi-agent discussions
- PM, Architect, Developer, Analyst, UX Designer, etc. - all with distinct voices

**Zero Breaking Changes**
- Fully backward compatible - works without any TTS provider
- `TTS_INJECTION` markers are benign HTML comments if not processed
- No changes to existing agent behavior or non-TTS workflows

## Implementation Details

**Files Modified:**
- `tools/cli/installers/lib/core/installer.js` - TTS injection processing logic
- `tools/cli/lib/ui.js` - AgentVibes detection and installation prompts
- `tools/cli/commands/install.js` - Post-install guidance for AgentVibes setup
- `src/utility/models/fragments/activation-rules.xml` - TTS_INJECTION marker for agents
- `src/core/workflows/party-mode/instructions.md` - TTS_INJECTION marker for party mode

**Injection Point System:**
```xml
<rules>
  - ALWAYS communicate in {communication_language}
  <!-- TTS_INJECTION:agent-tts -->
  - Stay in character until exit selected
</rules>
```

When AgentVibes is detected, the installer replaces this marker with:
```
- When responding to user messages, speak your responses using TTS:
  Call: `.claude/hooks/bmad-speak.sh '{agent-id}' '{response-text}'` after each response
  IMPORTANT: Use single quotes - do NOT escape special characters like ! or $
```

**Special Character Handling:**
- Explicit guidance to use single quotes without escaping
- Prevents "backslash exclamation" artifacts in speech

**User Experience:**
```
User: "How should we architect this feature?"
Architect: [Text response] + 🔊 [Professional voice explains architecture]
```

Party Mode:
```
PM (John): "I'll focus on user value..." 🔊 [Male professional voice]
UX Designer (Sara): "From a user perspective..." 🔊 [Female voice]
Architect (Marcus): "The technical approach..." 🔊 [Male technical voice]
```

## Testing

**Unit Tests:** ✅ 62/62 passing
- 49/49 schema validation tests
- 13/13 installation component tests

**Integration Testing:**
- ✅ BMAD → AgentVibes (automatic injection)
- ✅ AgentVibes → BMAD (automatic injection)
- ✅ No TTS provider (markers remain as comments)

## Documentation

Comprehensive testing guide created with:
- Both installation scenario walkthroughs
- Verification commands and expected outputs
- Troubleshooting guidance

## Known Limitations

**AgentVibes → BMAD Installation Order:**
When AgentVibes installs first, voice assignment file must be created manually:
```bash
mkdir -p .bmad/_cfg
cat > .bmad/_cfg/agent-voice-map.csv << 'EOF'
agent_id,voice_name
pm,en_US-ryan-high
architect,en_US-danny-low
dev,en_US-joe-medium
EOF
```

This limitation exists to prevent false legacy v4 detection warnings from BMAD installer.

**Recommended:** Install BMAD first, then AgentVibes for automatic voice assignment.

## Related Work

**Companion Implementation:**
- Repository: paulpreibisch/AgentVibes
- Commits: 6 commits implementing injection processing and voice routing
- Features: Retroactive injection, file path extraction, escape stripping

**GitHub Issues:**
- paulpreibisch/AgentVibes#36 - BMAD agent ID support

## Breaking Changes

None. Feature is opt-in and requires separate TTS provider installation.

* fix: Enforce project hooks over global hooks in party mode

before, claude would sometimes favor global agent vibes hooks over project specific

* feat: Automate AgentVibes installer invocation after BMAD install

Instead of showing manual installation instructions, the installer now:
- Prompts "Press Enter to start AgentVibes installer..."
- Automatically runs npx agentvibes@latest install
- Handles errors gracefully with fallback instructions

This provides a seamless installation flow matching the test script's
interactive approach.

* docs: Add automated testing script and guide for PR #934

Added comprehensive testing tools for AgentVibes party mode integration:

- test-bmad-pr.sh: Fully automated installation and verification script
  - Interactive mode selection (official PR or custom fork)
  - Automatic BMAD CLI setup and linking
  - AgentVibes installation with guided prompts
  - Built-in verification checks for voice maps and hooks
  - Saved configuration for quick re-testing

- TESTING.md: Complete testing documentation
  - Quick start with one-line npx command
  - Manual installation alternative
  - Troubleshooting guide
  - Cleanup instructions

Testers can now run a single command to test the full AgentVibes integration
without needing to understand the complex setup process.

* fix: Add shell: true to npx execSync to prevent permission denied error

The execSync call for 'npx agentvibes@latest install' was failing with
'Permission denied' because the shell was trying to execute 'agentvibes@latest'
directly instead of passing it as an argument to npx.

Adding shell: true ensures the command runs in a proper shell context
where npx can correctly interpret the @latest version syntax.

* fix: Remove duplicate AgentVibes installation step from test script

The test script was calling AgentVibes installer twice:
1. BMAD installer now automatically runs AgentVibes (new feature)
2. Test script had a separate Step 6 that also ran AgentVibes

This caused the installer to run twice, with the second call failing
because it was already installed.

Changes:
- Removed redundant Step 6 (AgentVibes installation)
- Updated Step 5 to indicate it includes AgentVibes
- Updated step numbers from 7 to 6 throughout
- Added guidance that AgentVibes runs automatically

Now the flow is cleaner: BMAD installer handles everything!

* fix: Address bmadcode review - preserve variables and move TTS logic to injection

Fixes requested changes from PR review:

1. Preserve {bmad_folder} variable placeholder
   - Changed: {project_root}/.bmad/core/tasks/workflow.xml
   - To: {project_root}/{bmad_folder}/core/tasks/workflow.xml
   - Allows users to choose custom BMAD folder names during installation

2. Move TTS-specific hook guidance to injection system
   - Removed hardcoded hook enforcement from source files
   - Added hook guidance to processTTSInjectionPoints() in installer.js
   - Now only appears when AgentVibes is installed (via TTS_INJECTION)

3. Maintain TTS-agnostic source architecture
   - Source files remain clean of TTS-specific instructions
   - TTS details injected at install-time only when needed
   - Preserves provider-agnostic design principle

Changes made:
- src/core/workflows/party-mode/instructions.md
  - Reverted .bmad to {bmad_folder} variable
  - Replaced hardcoded hook guidance with <!-- TTS_INJECTION:party-mode -->
  - Removed <note> about play-tts.sh hook location

- tools/cli/installers/lib/core/installer.js
  - Added hook enforcement to party-mode injection replacement
  - Guidance now injected only when enableAgentVibes is true

Addresses review comments from bmadcode:
- "needs to remain the variable. it will get set in the file at the install destination."
- "items like this we will need to inject if user is using claude and TTS"

* fix: Change 'claude-code' to 'claude' in test script instructions

The correct command to start Claude is 'claude', not 'claude-code'.
Updated line 362-363 in test-bmad-pr.sh to show the correct command.

* fix: Remove npm link from test script to avoid global namespace pollution

- Removed 'npm link' command that was installing BMAD globally
- Changed 'bmad install' to direct node execution using local clone
- Updated success message to reflect no global installation

This keeps testing fully isolated and prevents conflicts with:
- Existing BMAD installations
- Future official BMAD installs
- Orphaned symlinks when test directory is deleted

The test script now runs completely self-contained without modifying
the user's global npm environment.

+# Testing AgentVibes Party Mode (PR #934)
+
+This guide helps you test the AgentVibes integration that adds multi-agent party mode with unique voices for each BMAD agent.
+
+## Quick Start
+
+We've created an automated test script that handles everything for you:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/paulpreibisch/BMAD-METHOD/feature/agentvibes-tts-integration/test-bmad-pr.sh -o test-bmad-pr.sh
+chmod +x test-bmad-pr.sh
+./test-bmad-pr.sh
+```
+
+## What the Script Does
+
+The automated script will:
+
+1. Clone the BMAD repository
+2. Checkout the PR branch with party mode features
+3. Install BMAD CLI tools locally
+4. Create a test BMAD project
+5. Install AgentVibes TTS system
+6. Configure unique voices for each agent
+7. Verify the installation
+
+## Prerequisites
+
+- Node.js and npm installed
+- Git installed
+- ~500MB free disk space
+- 10-15 minutes for complete setup
+
+## Manual Testing (Alternative)
+
+If you prefer manual installation:
+
+### 1. Clone and Setup BMAD
+
+```bash
+git clone https://github.com/paulpreibisch/BMAD-METHOD.git
+cd BMAD-METHOD
+git fetch origin pull/934/head:agentvibes-party-mode
+git checkout agentvibes-party-mode
+cd tools/cli
+npm install
+npm link
+```
+
+### 2. Create Test Project
+
+```bash
+mkdir -p ~/bmad-test-project
+cd ~/bmad-test-project
+bmad install
+```
+
+When prompted:
+
+- Enable TTS for agents? → **Yes**
+- The installer will automatically prompt you to install AgentVibes
+
+### 3. Test Party Mode
+
+```bash
+cd ~/bmad-test-project
+claude-code
+```
+
+In Claude Code, run:
+
+```
+/bmad:core:workflows:party-mode
+```
+
+Each BMAD agent should speak with a unique voice!
+
+## Verification
+
+After installation, verify:
+
+✅ Voice map file exists: `.bmad/_cfg/agent-voice-map.csv`
+✅ BMAD TTS hooks exist: `.claude/hooks/bmad-speak.sh`
+✅ Each agent has a unique voice assigned
+✅ Party mode works with distinct voices
+
+## Troubleshooting
+
+**No audio?**
+
+- Check: `.claude/hooks/play-tts.sh` exists
+- Test current voice: `/agent-vibes:whoami`
+
+**Same voice for all agents?**
+
+- Check: `.bmad/_cfg/agent-voice-map.csv` has different voices
+- List available voices: `/agent-vibes:list`
+
+## Report Issues
+
+Found a bug? Report it on the PR:
+https://github.com/bmad-code-org/BMAD-METHOD/pull/934
+
+## Cleanup
+
+To remove the test installation:
+
+```bash
+# Remove test directory
+rm -rf ~/bmad-test-project  # or your custom test directory
+
+# Unlink BMAD CLI (optional)
+cd ~/BMAD-METHOD/tools/cli
+npm unlink
+```

+   * AI NOTE: This implements the injection point pattern for TTS integration.
+   * Key architectural decisions:
+   *
+   * 1. **Why Injection Points vs Direct Integration?**
+   *    - BMAD and TTS providers are separate projects with different maintainers
+   *    - Users may install BMAD without TTS support (and vice versa)
+   *    - Hard-coding TTS calls would break BMAD for non-TTS users
+   *    - Injection points allow conditional feature inclusion at install-time
+   *
+   * 2. **How It Works:**
+   *    - BMAD source contains markers: <!-- TTS_INJECTION:feature-name -->
+   *    - During installation, user is prompted: "Enable AgentVibes TTS?"
+   *    - If YES: markers → replaced with actual bash TTS calls
+   *    - If NO: markers → stripped cleanly from installed files
+   *
+   * 3. **State Management:**
+   *    - this.enableAgentVibes set in install() method from config.enableAgentVibes
+   *    - config.enableAgentVibes comes from ui.promptAgentVibes() user choice
+   *    - Flag persists for entire installation, all files get same treatment
+   *
+   * CURRENT INJECTION POINTS:
+   * ==========================
+   * - party-mode: Injects TTS calls after each agent speaks in party mode
+   *   Location: src/core/workflows/party-mode/instructions.md
+   *   Marker: <!-- TTS_INJECTION:party-mode -->
+   *   Replacement: Bash call to .claude/hooks/bmad-speak.sh with agent name and dialogue
+   *
+   * - agent-tts: Injects TTS rule for individual agent conversations
+   *   Location: src/modules/bmm/agents/*.md (all agent files)
+   *   Marker: <!-- TTS_INJECTION:agent-tts -->
+   *   Replacement: Rule instructing agent to call bmad-speak.sh with agent ID and response
+   *
+   * ADDING NEW INJECTION POINTS:
+   * =============================
+   * 1. Add new case in this function:
+   *    content = content.replace(
+   *      /<!-- TTS_INJECTION:new-feature -->/g,
+   *      `code to inject when enabled`
+   *    );
+   *
+   * 2. Add marker to BMAD source file at injection location
