+# Desktop Notifications
+
+Fabric supports desktop notifications to alert you when commands complete, which is especially useful for long-running tasks or when you're multitasking.
+
+## Quick Start
+
+Enable notifications with the `--notification` flag:
+
+```bash
+fabric --pattern summarize --notification < article.txt
+```
+
+## Configuration
+
+### Command Line Options
+
+- `--notification`: Enable desktop notifications when command completes
+- `--notification-command`: Use a custom notification command instead of built-in notifications
+
+### YAML Configuration
+
+Add notification settings to your `~/.config/fabric/config.yaml`:
+
+```yaml
+# Enable notifications by default
+notification: true
+
+# Optional: Custom notification command
+notificationCommand: 'notify-send --urgency=normal "$1" "$2"'
+```
+
+## Platform Support
+
+### macOS
+
+- **Default**: Uses `osascript` (built into macOS)
+- **Enhanced**: Install `terminal-notifier` for better notifications:
+
+  ```bash
+  brew install terminal-notifier
+  ```
+
+### Linux
+
+- **Requirement**: Install `notify-send`:
+
+  ```bash
+  # Ubuntu/Debian
+  sudo apt install libnotify-bin
+
+  # Fedora
+  sudo dnf install libnotify
+  ```
+
+### Windows
+
+- **Default**: Uses PowerShell message boxes (built-in)
+
+## Custom Notification Commands
+
+The `--notification-command` flag allows you to use custom notification scripts or commands. The command receives the title as `$1` and message as `$2` as shell positional arguments.
+
+**Security Note**: The title and message content are properly escaped to prevent command injection attacks from AI-generated output containing shell metacharacters.
+
+### Examples
+
+**macOS with custom sound:**
+
+```bash
+fabric --pattern analyze_claims --notification-command 'osascript -e "display notification \"$2\" with title \"$1\" sound name \"Ping\""' < document.txt
+```
+
+**Linux with urgency levels:**
+
+```bash
+fabric --pattern extract_wisdom --notification-command 'notify-send --urgency=critical "$1" "$2"' < video-transcript.txt
+```
+
+**Custom script:**
+
+```bash
+fabric --pattern summarize --notification-command '/path/to/my-notification-script.sh "$1" "$2"' < report.pdf
+```
+
+**Testing your custom command:**
+
+```bash
+# Test that $1 and $2 are passed correctly
+fabric --pattern raw_query --notification-command 'echo "Title: $1, Message: $2"' "test input"
+```
+
+## Notification Content
+
+Notifications include:
+
+- **Title**: "Fabric Command Complete" or "Fabric: [pattern] Complete"
+- **Message**: Brief summary of the output (first 100 characters)
+
+For long outputs, the message is truncated with "..." to fit notification display limits.
+
+## Use Cases
+
+### Long-Running Tasks
+
+```bash
+# Process large document with notifications
+fabric --pattern analyze_paper --notification < research-paper.pdf
+
+# Extract wisdom from long video with alerts
+fabric -y "https://youtube.com/watch?v=..." --pattern extract_wisdom --notification
+```
+
+### Background Processing
+
+```bash
+# Process multiple files and get notified when each completes
+for file in *.txt; do
+    fabric --pattern summarize --notification < "$file" &
+done
+```
+
+### Integration with Other Tools
+
+```bash
+# Combine with other commands
+curl -s "https://api.example.com/data" | \
+    fabric --pattern analyze_data --notification --output results.md
+```
+
+## Troubleshooting
+
+### No Notifications Appearing
+
+1. **Check system notifications are enabled** for Terminal/your shell
+2. **Verify notification tools are installed**:
+   - macOS: `which osascript` (should exist)
+   - Linux: `which notify-send`
+   - Windows: `where.exe powershell`
+
+3. **Test with simple command**:
+
+   ```bash
+   echo "test" | fabric --pattern raw_query --notification --dry-run
+   ```
+
+### Notification Permission Issues
+
+On some systems, you may need to grant notification permissions to your terminal application:
+
+- **macOS**: System Preferences → Security & Privacy → Privacy → Notifications → Enable for Terminal
+- **Linux**: Depends on desktop environment; usually automatic
+- **Windows**: Usually works by default
+
+### Custom Commands Not Working
+
+- Ensure your custom notification command is executable
+- Test the command manually with sample arguments
+- Check that all required dependencies are installed
+
+## Advanced Configuration
+
+### Environment-Specific Settings
+
+Create different configuration files for different environments:
+
+```bash
+# Work computer (quieter notifications)
+fabric --config ~/.config/fabric/work-config.yaml --notification
+
+# Personal computer (with sound)
+fabric --config ~/.config/fabric/personal-config.yaml --notification
+```
+
+### Integration with Task Management
+
+```bash
+# Custom script that also logs to task management system
+notificationCommand: '/usr/local/bin/fabric-notify-and-log.sh "$1" "$2"'
+```
+
+## Examples
+
+See `docs/notification-config.yaml` for a complete configuration example with various notification command options.

+- Generate high-quality WAV audio files
+- Integrate TTS generation into your existing Fabric workflows
+
+## Usage
+
+### Basic TTS Generation
+
+To generate audio from text using TTS:
+
+```bash
+# Basic TTS with default voice (Kore)
+echo "Hello, this is a test of Gemini TTS" | fabric -m gemini-2.5-flash-preview-tts -o output.wav
+
+# Using a specific voice
+echo "Hello, this is a test with the Charon voice" | fabric -m gemini-2.5-flash-preview-tts --voice Charon -o output.wav
+
+# Using TTS with a pattern
+fabric -p summarize --voice Puck -m gemini-2.5-flash-preview-tts -o summary.wav < document.txt
+```
+
+### Voice Selection
+
+Use the `--voice` flag to specify which voice to use for TTS generation:
+
+```bash
+fabric -m gemini-2.5-flash-preview-tts --voice Zephyr -o output.wav "Your text here"
+```
+
+If no voice is specified, the default voice "Kore" will be used.

+# YouTube Processing with Fabric
+
+Fabric provides powerful YouTube video processing capabilities that allow you to extract transcripts, comments, and metadata from YouTube videos and playlists. This guide covers all the available options and common use cases.
+
+## Prerequisites
+
+- **yt-dlp**: Required for transcript extraction. Install on MacOS with:
+
+  ```bash
+  brew install yt-dlp
+  ```
+
+  Or use the package manager of your choice for your operating system.
+
+  See the [yt-dlp wiki page](https://github.com/yt-dlp/yt-dlp/wiki/Installation) for your specific installation instructions.
+
+- **YouTube API Key** (optional): Only needed for comments and metadata extraction. Configure with:
+
+  ```bash
+  fabric --setup
+  ```
+
+## Basic Usage
+
+### Extract Transcript
+
+Extract a video transcript and process it with a pattern:
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern summarize
+```
+
+### Extract Transcript with Timestamps
+
+Get transcript with timestamps preserved:
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --transcript-with-timestamps --pattern extract_wisdom
+```
+
+### Extract Comments
+
+Get video comments (requires YouTube API key):
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --comments --pattern analyze_claims
+```
+
+### Extract Metadata
+
+Get video metadata as JSON:
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --metadata
+```
+
+## Advanced Options
+
+### Custom yt-dlp Arguments
+
+Pass additional arguments to yt-dlp for advanced functionality. **User-provided arguments take precedence** over built-in fabric arguments, giving you full control:
+
+```bash
+# Use browser cookies for age-restricted or private videos
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--cookies-from-browser brave"
+
+# Override language selection (takes precedence over -g flag)
+fabric -g en -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--sub-langs es,fr"
+
+# Use specific format
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--format best"
+
+# Handle rate limiting (slow down requests)
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--sleep-requests 1"
+
+# Multiple arguments (use quotes)
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--cookies-from-browser firefox --write-info-json"
+
+# Combine rate limiting with authentication
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--cookies-from-browser brave --sleep-requests 1"
+
+# Override subtitle format (takes precedence over built-in --sub-format vtt)
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --yt-dlp-args "--sub-format srt"
+```
+
+#### Argument Precedence
+
+Fabric constructs the yt-dlp command in this order:
+
+1. **Built-in base arguments** (`--write-auto-subs`, `--skip-download`, etc.)
+2. **Language selection** (from `-g` flag): `--sub-langs LANGUAGE`
+3. **User arguments** (from `--yt-dlp-args`): **These override any conflicting built-in arguments**
+4. **Video URL**
+
+This means you can override any built-in behavior by specifying it in `--yt-dlp-args`.
+
+### Playlist Processing
+
+Process entire playlists:
+
+```bash
+# Process all videos in a playlist
+fabric -y "https://www.youtube.com/playlist?list=PLAYLIST_ID" --playlist --pattern summarize
+
+# Save playlist videos to CSV
+fabric -y "https://www.youtube.com/playlist?list=PLAYLIST_ID" --playlist -o playlist.csv
+```
+
+### Language Support
+
+Specify transcript language:
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" -g es --pattern translate
+```
+
+## Combining Options
+
+You can combine multiple YouTube processing options:
+
+```bash
+# Get transcript, comments, and metadata
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" \
+  --transcript \
+  --comments \
+  --metadata \
+  --pattern comprehensive_analysis
+```
+
+## Output Options
+
+### Save to File
+
+```bash
+# Save output to file
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern summarize -o summary.md
+
+# Save entire session including input
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern summarize --output-session -o full_session.md
+```
+
+### Stream Output
+
+Get real-time streaming output:
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern summarize --stream
+```
+
+## Common Use Cases
+
+### Content Analysis
+
+```bash
+# Analyze video content for key insights
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern extract_wisdom
+
+# Check claims made in the video
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern analyze_claims
+```
+
+### Educational Content
+
+```bash
+# Create study notes from educational videos
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern create_study_notes

+
+# Extract action items from recorded meetings
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern extract_action_items
+```
+
+### Content Creation
+
+```bash
+# Create social media posts from video content
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern create_social_posts
+
+# Generate blog post from video transcript
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern write_blog_post
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"yt-dlp not found"**: Install yt-dlp using pip or your package manager
+2. **Age-restricted videos**: Use `--yt-dlp-args "--cookies-from-browser BROWSER"`
+3. **No subtitles available**: Some videos don't have auto-generated subtitles
+4. **API rate limits**: YouTube API has daily quotas for comments/metadata
+5. **HTTP 429 errors**: YouTube is rate limiting subtitle requests
+
+### Error Messages
+
+- **"YouTube is not configured"**: Run `fabric --setup` to configure YouTube API
+- **"yt-dlp failed"**: Check video URL and try with `--yt-dlp-args` for authentication
+- **"No transcript content found"**: Video may not have subtitles available
+- **"HTTP Error 429: Too Many Requests"**: YouTube rate limit exceeded. This is increasingly common. Solutions:
+  - **Wait 10-30 minutes and try again** (most effective)
+  - Use longer sleep: `--yt-dlp-args "--sleep-requests 5"`
+  - Try with browser cookies: `--yt-dlp-args "--cookies-from-browser brave --sleep-requests 5"`
+  - **Try a different video** - some videos are less restricted
+  - **Use a VPN** - different IP address may help
+  - **Try without language specification** - let yt-dlp choose any available language
+  - **Try English instead** - `fabric -g en` (English subtitles may be less rate-limited)
+
+### Language Fallback Behavior
+
+When you specify a language (e.g., `-g es` for Spanish) but that language isn't available or fails to download:
+
+1. **Automatic fallback**: Fabric automatically retries without language specification
+2. **Smart file detection**: If the fallback downloads a different language (e.g., English), Fabric will automatically detect and use it
+3. **No manual intervention needed**: The process is transparent to the user
+
+```bash
+# Even if Spanish isn't available, this will work with whatever language yt-dlp finds
+fabric -g es -y "https://youtube.com/watch?v=VIDEO_ID" --pattern summarize
+```
+
+## Configuration
+
+### YAML Configuration
+
+You can set default yt-dlp arguments in your config file (`~/.config/fabric/config.yaml`):
+
+```yaml
+ytDlpArgs: "--cookies-from-browser brave --write-info-json"
+```
+
+### Environment Variables
+
+Set up your YouTube API key:
+
+```bash
+export FABRIC_YOUTUBE_API_KEY="your_api_key_here"
+```
+
+## Tips and Best Practices
+
+1. **Use specific patterns**: Choose patterns that match your use case for better results
+2. **Combine with other tools**: Pipe output to other commands or save to files for further processing
+3. **Batch processing**: Use playlists to process multiple videos efficiently
+4. **Authentication**: Use browser cookies for accessing private or age-restricted content
+5. **Language support**: Specify language codes for better transcript accuracy
+6. **Rate limiting**: If you encounter 429 errors, use `--sleep-requests 1` to slow down requests
+7. **Persistent settings**: Set common yt-dlp args in your config file to avoid repeating them
+8. **Argument precedence**: Use `--yt-dlp-args` to override any built-in behavior when needed
+9. **Testing**: Use `yt-dlp --list-subs URL` to see available subtitle languages before processing
+
+## Examples
+
+### Quick Video Summary
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=dQw4w9WgXcQ" --pattern summarize --stream
+```
+
+### Detailed Analysis with Authentication
+
+```bash
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" \
+  --yt-dlp-args "--cookies-from-browser chrome" \
+  --transcript-with-timestamps \
+  --comments \
+  --pattern comprehensive_analysis \
+  -o analysis.md
+```
+
+### Playlist Processing
+
+```bash
+fabric -y "https://www.youtube.com/playlist?list=PLrAXtmRdnEQy6nuLvVUxpDnx4C0823vBN" \
+  --playlist \
+  --pattern extract_wisdom \
+  -o playlist_wisdom.md
+```
+
+### Override Built-in Language Selection
+
+```bash
+# Built-in language selection (-g es) is overridden by user args
+fabric -g es -y "https://www.youtube.com/watch?v=VIDEO_ID" \
+  --yt-dlp-args "--sub-langs fr,de,en" \
+  --pattern translate
+```

+This directory contains sample audio files demonstrating different Gemini TTS voices.
+
+## Sample Files
+
+Each voice sample says "The quick brown fox jumped over the lazy dog" to demonstrate the voice characteristics:
+
+- **Kore.wav** - Firm and confident (default voice)
+- **Charon.wav** - Informative and clear
+- **Vega.wav** - Smooth and pleasant
+- **Capella.wav** - Warm and welcoming
+- **Achird.wav** - Friendly and approachable
+- **Lyra.wav** - Melodic and expressive
+
+## Generating Samples
+
+To generate these samples, use the following commands:
+
+```bash
+# Generate each voice sample
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Kore -o docs/voices/Kore.wav
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Charon -o docs/voices/Charon.wav
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Vega -o docs/voices/Vega.wav
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Capella -o docs/voices/Capella.wav
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Achird -o docs/voices/Achird.wav
+echo "The quick brown fox jumped over the lazy dog" | fabric -m gemini-2.5-flash-preview-tts --voice Lyra -o docs/voices/Lyra.wav
+```
+
+## Audio Format

+# Docker Test Environment for API Configuration Fix
+
+This directory contains a Docker-based testing setup for fixing the issue where Fabric calls Ollama and Bedrock APIs even when not configured. This addresses the problem where unconfigured services show error messages during model listing.
+
+## Quick Start
+
+```bash
+# Run all tests
+./scripts/docker-test/test-runner.sh
+
+# Interactive mode - pick which test to run
+./scripts/docker-test/test-runner.sh -i
+
+# Run specific test case
+./scripts/docker-test/test-runner.sh gemini-only
+
+# Shell into test environment
+./scripts/docker-test/test-runner.sh -s gemini-only
+
+# Build image only (for development)
+./scripts/docker-test/test-runner.sh -b
+
+# Show help
+./scripts/docker-test/test-runner.sh -h
+```
+
+## Test Cases
+
+1. **no-config**: No APIs configured
+2. **gemini-only**: Only Gemini configured (reproduces original issue #1195)
+3. **openai-only**: Only OpenAI configured
+4. **ollama-only**: Only Ollama configured
+5. **bedrock-only**: Only Bedrock configured
+6. **mixed**: Multiple APIs configured (Gemini + OpenAI + Ollama)
+
+## Environment Files

+Each test case has a corresponding environment file in `scripts/docker-test/env/`:
+
+- `env.no-config` - Empty configuration
+- `env.gemini-only` - Only Gemini API key
+- `env.openai-only` - Only OpenAI API key
+- `env.ollama-only` - Only Ollama URL
+- `env.bedrock-only` - Only Bedrock configuration
+- `env.mixed` - Multiple API configurations
+
+These files are volume-mounted into the Docker container and persist changes made with `fabric -S`.
+
+## Interactive Mode & Shell Access
+
+The interactive mode (`-i`) provides several options:
+
+```text
+Available test cases:
+
+1) No APIs configured (no-config)
+2) Only Gemini configured (gemini-only)
+3) Only OpenAI configured (openai-only)
+4) Only Ollama configured (ollama-only)
+5) Only Bedrock configured (bedrock-only)
+6) Mixed configuration (mixed)
+7) Run all tests
+0) Exit
+
+Add '!' after number to shell into test environment (e.g., '1!' to shell into no-config)
+```
+
+### Shell Mode
+
+- Use `1!`, `2!`, etc. to shell into any test environment
+- Run `fabric -S` to configure APIs interactively
+- Run `fabric --listmodels` or `fabric -L` to test model listing
+- Changes persist in the environment files
+- Type `exit` to return to test runner
+
+## Expected Results
+
+**Before Fix:**
+
+- `no-config` and `gemini-only` tests show Ollama connection errors
+- Tests show Bedrock authentication errors when BEDROCK_AWS_REGION not set
+- Error: `Ollama Get "http://localhost:11434/api/tags": dial tcp...`
+- Error: `Bedrock failed to list foundation models...`
+
+**After Fix:**
+
+- Clean output with no error messages for unconfigured services
+- Only configured services appear in model listings
+- Ollama only initialized when `OLLAMA_API_URL` is set
+- Bedrock only initialized when `BEDROCK_AWS_REGION` is set
+
+## Implementation Details
+
+- **Volume-mounted configs**: Environment files are mounted to `/home/testuser/.config/fabric/.env`
+- **Persistent state**: Configuration changes survive between test runs
+- **Single Docker image**: Built once from `scripts/docker-test/base/Dockerfile`, reused for all tests
+- **Isolated environments**: Each test uses its own environment file
+- **Cross-platform**: Works on macOS, Linux, and Windows with Docker
+
+## Development Workflow
+
+1. Make code changes to fix API initialization logic
+2. Run `./scripts/docker-test/test-runner.sh no-config` to test the main issue
+3. Use `./scripts/docker-test/test-runner.sh -i` for interactive testing
+4. Shell into environments (`1!`, `2!`, etc.) to debug specific configurations
+5. Run all tests before submitting PR: `./scripts/docker-test/test-runner.sh`
+
+## Architecture
+
+The fix involves:
+
+1. **Ollama**: Override `IsConfigured()` method to check for `OLLAMA_API_URL` env var
+2. **Bedrock**: Modify `hasAWSCredentials()` to require `BEDROCK_AWS_REGION`
+3. **Plugin Registry**: Only initialize providers when properly configured
+
+This prevents unnecessary API calls and eliminates confusing error messages for users.
