+
+DESCRIPTION:
+    This script automatically installs shell completions for the fabric CLI
+    based on your current shell and the installed fabric command name.
+
+        The script will use completion files from the same directory as the script
+        when available. If they are not present (e.g., when running via curl), it
+        will download them from GitHub:
+
+            $FABRIC_COMPLETIONS_BASE_URL
+
+        You can override the download source by setting
+        FABRIC_COMPLETIONS_BASE_URL to your preferred location.
+
+    Supports: zsh, bash, fish
+
+    The script will:
+    1. Detect whether 'fabric' or 'fabric-ai' is installed
+    2. Detect your current shell from the SHELL environment variable
+    3. Install the appropriate completion file with the correct name
+    4. Try multiple standard completion directories
+
+EXAMPLES:
+        ./setup-completions.sh                  # Install completions
+        ./setup-completions.sh --dry-run        # Show what would be done

+# Automated CHANGELOG Entry System for CI/CD
+
+## Overview
+
+This document outlines a comprehensive system for automatically generating and maintaining CHANGELOG.md entries during the CI/CD process. The system builds upon the existing `generate_changelog` tool and integrates seamlessly with GitHub's pull request workflow.
+
+## Current State Analysis
+
+### Existing Infrastructure
+
+The `generate_changelog` tool already provides:
+
+- **High-performance Git history walking** with one-pass algorithm
+- **GitHub API integration** with GraphQL optimization and smart caching
+- **SQLite-based caching** for instant incremental updates
+- **AI-powered summaries** using Fabric integration
+- **Concurrent processing** for optimal performance
+- **Version detection** from git tags and commit patterns
+
+### Key Components
+
+- **Main entry point**: `cmd/generate_changelog/main.go`
+- **Core generation logic**: `internal/changelog/generator.go`
+- **AI summarization**: `internal/changelog/summarize.go`
+- **Caching system**: `internal/cache/cache.go`
+- **GitHub integration**: `internal/github/client.go`
+- **Git operations**: `internal/git/walker.go`
+
+## Proposed Automated System
+
+### Developer Workflow
+
+```mermaid
+graph TD
+    A[Developer creates feature branch] --> B[Codes feature]
+    B --> C[Creates Pull Request]
+    C --> D[PR is open and ready]
+    D --> E[Developer runs: generate_changelog --incoming-pr XXXX]
+    E --> F[Tool validates PR is open/mergeable]
+    F --> G[Tool creates incoming/XXXX.txt with AI summary]
+    G --> H[Auto-commit and push to branch]
+    H --> I[PR includes pre-processed changelog entry]
+    I --> J[PR gets reviewed and merged]
+```
+
+### CI/CD Integration
+
+```mermaid
+graph TD
+    A[PR merged to main] --> B[Version bump workflow triggered]
+    B --> C[generate_changelog --process-prs]
+    C --> D[Scan incoming/ directory]
+    D --> E[Concatenate all incoming/*.txt files]
+    E --> F[Insert new version at top of CHANGELOG.md]
+    F --> G[Store entry in versions table]
+    G --> H[git rm incoming/*.txt files]
+    H --> I[git add CHANGELOG.md and changelog.db, done by the tool]
+    I --> J[Increment version number]
+    J --> K[Commit and tag release]
+```
+
+## Implementation Details
+
+### Phase 1: Pre-Processing PRs
+
+#### New Command: `--incoming-pr`
+
+**Usage**: `generate_changelog --incoming-pr 1672`
+
+**Functionality**:
+
+1. **Validation**:
+   - Verify PR exists and is open
+   - Check PR is mergeable
+   - Ensure branch is up-to-date
+   - Verify that current git repo is clean (everything committed); do not continue otherwise.
+
+2. **Content Generation**:
+   - Extract PR metadata (title, author, description)
+   - Collect all commit messages from the PR
+   - Use existing `SummarizeVersionContent` function for AI enhancement
+   - Format as standard changelog entry
+
+3. **File Creation**:
+   - Generate `./cmd/generate_changelog/incoming/{PR#}.txt`
+   - Include PR header: `### PR [#1672](url) by [author](profile): Title` (as is done currently in the code)
+   - Consider extracting the existing header code for PRs into a helper function for re-use.
+   - Include the AI-summarized changes (generated when we ran all the commit messages through `SummarizeVersionContent`)
+
+4. **Auto-commit**:
+   - Commit file with message: `chore: incoming 1672 changelog entry`
+   - Optionally push to current branch (use `--push` flag)
+
+(The PR is now completely ready to be merged with integrated CHANGELOG entry updating)
+
+#### File Format Example
+
+```markdown
+### PR [#1672](https://github.com/danielmiessler/Fabric/pull/1672) by [ksylvan](https://github.com/ksylvan): Changelog Generator Enhancement
+
+- Added automated CI/CD integration for changelog generation
+- Implemented pre-processing of PR entries during development
+- Enhanced caching system for better performance
+- Added validation for mergeable PR states
+```
+
+### Phase 2: Release Processing
+
+#### New Command: `--process-prs`
+
+**Usage**: `generate_changelog --process-prs`
+
+**Integration Point**: `.github/workflows/update-version-and-create-tag.yml`
+
+(we can do this AFTER the "Update gomod2nix.toml file" step in the workflow, where we
+already have generated the next version in the "version.nix" file)
+
+**Functionality**:
+
+1. **Discovery**: Scan `./cmd/generate_changelog/incoming/` directory
+2. **Aggregation**: Read and concatenate all `*.txt` files
+3. **Version Creation**: Generate new version header with current date
+4. **CHANGELOG Update**: Insert new version at top of existing CHANGELOG.md
+5. **Database Update**: Store complete entry in `versions` table as `ai_summary`
+6. **Cleanup**: Remove all processed incoming files
+7. **Stage Changes**: Add modified files to git staging area
+
+#### Example Output in CHANGELOG.md
+
+```markdown

+```
+
+## Technical Implementation
+
+### Configuration Extensions
+
+Add to `internal/config/config.go`:
+
+```go
+type Config struct {
+    // ... existing fields
+    IncomingPR   int         // PR number for --incoming-pr
+    ProcessPRsVersion string // Flag for --process-prs (new version string)
+    IncomingDir  string      // Directory for incoming files (default: ./cmd/generate_changelog/incoming/)
+}
+```
+
+### New Command Line Flags
+
+```go
+rootCmd.Flags().IntVar(&cfg.IncomingPR, "incoming-pr", 0, "Pre-process PR for changelog (provide PR number)")
+rootCmd.Flags().StringVar(&cfg.ProcessPRsVersion, "process-prs", "", "Process all incoming PR files for release (provide version like v1.4.262)")
+rootCmd.Flags().StringVar(&cfg.IncomingDir, "incoming-dir", "./cmd/generate_changelog/incoming", "Directory for incoming PR files")
+```
+
+### Core Logic Extensions
+
+#### PR Pre-processing
+
+```go
+func (g *Generator) ProcessIncomingPR(prNumber int) error {
+    // 1. Validate PR state via GitHub API
+    pr, err := g.ghClient.GetPR(prNumber)
+    if err != nil || pr.State != "open" || !pr.Mergeable {
+        return fmt.Errorf("PR %d is not in valid state for processing", prNumber)
+    }
+
+    // 2. Generate changelog content using existing logic
+    content := g.formatPR(pr)
+
+    // 3. Apply AI summarization if enabled
+    if g.cfg.EnableAISummary {
+        content, _ = SummarizeVersionContent(content)
+    }
+
+    // 4. Write to incoming file
+    filename := filepath.Join(g.cfg.IncomingDir, fmt.Sprintf("%d.txt", prNumber))
+    err = os.WriteFile(filename, []byte(content), 0644)
+    if err != nil {
+        return fmt.Errorf("failed to write incoming file: %w", err)
+    }
+
+    // 5. Auto-commit and push
+    return g.commitAndPushIncoming(prNumber, filename)
+}
+```
+
+#### Release Processing
+
+```go
+func (g *Generator) ProcessIncomingPRs(version string) error {
+    // 1. Scan incoming directory
+    files, err := filepath.Glob(filepath.Join(g.cfg.IncomingDir, "*.txt"))
+    if err != nil || len(files) == 0 {
+        return fmt.Errorf("no incoming PR files found")
+    }
+
+    // 2. Read and concatenate all files
+    var content strings.Builder
+    for _, file := range files {
+        data, err := os.ReadFile(file)
+        if err == nil {
+            content.WriteString(string(data))
+            content.WriteString("\n")
+        }
+    }
+
+    // 3. Generate version entry
+    entry := fmt.Sprintf("\n## %s (%s)\n\n%s",
+        version, time.Now().Format("2006-01-02"), content.String())
+
+    // 4. Update CHANGELOG.md
+    err = g.insertVersionAtTop(entry)
+    if err != nil {
+        return fmt.Errorf("failed to update CHANGELOG.md: %w", err)
+    }
+
+    // 5. Update database
+    err = g.cache.SaveVersionEntry(version, content.String())
+    if err != nil {
+        return fmt.Errorf("failed to save to database: %w", err)
+    }
+
+    // 6. Cleanup incoming files
+    for _, file := range files {
+        os.Remove(file)
+    }
+
+    return nil
+}
+```
+
+## Workflow Integration
+
+### GitHub Actions Modification
+
+Update `.github/workflows/update-version-and-create-tag.yml`.
+
+```yaml
+- name: Generate Changelog Entry
+  run: |
+    # Process all incoming PR entries
+    ./cmd/generate_changelog/generate_changelog --process-prs
+
+    # The tool will make the needed changes in the CHANGELOG.md,
+    # and the changelog.db, and will remove the PR#.txt file(s)
+    # In effect, doing the following:
+    # 1. Generate the new CHANGELOG (and store the entry in the changelog.db)
+    # 2. git add CHANGELOG.md
+    # 3. git add ./cmd/generate_changelog/changelog.db
+    # 4. git rm -rf ./cmd/generate_changelog/incoming/
+    #
+```
+
+### Developer Instructions
+
+1. **During Development**:
+
+   ```bash
+   # After PR is ready for review (commit locally only)
+   generate_changelog --incoming-pr 1672 --ai-summarize
+
+   # Or to automatically push to remote
+   generate_changelog --incoming-pr 1672 --ai-summarize --push
+   ```
+
+2. **Validation**:
+   - Check that `incoming/1672.txt` was created
+   - Verify auto-commit occurred

+# Automated Changelog System - Developer Guide
+
+This guide explains how to use the new automated changelog system for the Fabric project.
+
+## Overview
+
+The automated changelog system allows developers to pre-process their PR changelog entries during development, which are then automatically aggregated during the release process. This eliminates manual CHANGELOG.md editing and reduces merge conflicts.
+
+## Developer Workflow
+
+### Step 1: Create Your Feature Branch and PR
+
+Work on your feature as usual and create a pull request.
+
+### Step 2: Generate Changelog Entry
+
+Once your PR is ready for review, generate a changelog entry:
+
+```bash
+cd cmd/generate_changelog
+go build -o generate_changelog .
+./generate_changelog --incoming-pr YOUR_PR_NUMBER
+```
+
+For example, if your PR number is 1672:
+
+```bash
+./generate_changelog --incoming-pr 1672
+```
+
+### Step 3: Validation
+
+The tool will validate:
+
+- ✅ PR exists and is open
+- ✅ PR is mergeable (no conflicts)
+- ✅ Your working directory is clean
+
+If any validation fails, fix the issues and try again.
+
+### Step 4: Review Generated Entry
+
+The tool will:
+
+1. Create `./cmd/generate_changelog/incoming/1672.txt`
+2. Generate an AI-enhanced summary (if `--ai-summarize` is enabled)
+3. Auto-commit the file to your branch (use `--push` to also push to remote)
+
+Review the generated file and edit if needed:
+
+```bash
+cat ./cmd/generate_changelog/incoming/1672.txt
+```
+
+### Step 5: Include in PR
+
+The incoming changelog entry is now part of your PR and will be reviewed along with your code changes.
+
+## Example Generated Entry
+
+```markdown
+### PR [#1672](https://github.com/danielmiessler/fabric/pull/1672) by [ksylvan](https://github.com/ksylvan): Changelog Generator Enhancement
+
+- Added automated CI/CD integration for changelog generation
+- Implemented pre-processing of PR entries during development
+- Enhanced caching system for better performance
+- Added validation for mergeable PR states
+```
+
+## Command Options
+
+### `--incoming-pr`
+
+Pre-process a specific PR for changelog generation.
+
+**Usage**: `./generate_changelog --incoming-pr PR_NUMBER`
+
+**Requirements**:
+
+- PR must be open
+- PR must be mergeable (no conflicts)
+- Working directory must be clean (no uncommitted changes)
+- GitHub token must be available (`GITHUB_TOKEN` env var or `--token` flag)
+
+**Mutual Exclusivity**: Cannot be used with `--process-prs` flag
+
+### `--incoming-dir`
+
+Specify custom directory for incoming PR files (default: `./cmd/generate_changelog/incoming`).
+
+**Usage**: `./generate_changelog --incoming-pr 1672 --incoming-dir ./custom/path`
+
+### `--process-prs`
+
+Process all incoming PR files for release aggregation. Used by CI/CD during release creation.
+
+**Usage**: `./generate_changelog --process-prs {new_version_string}`
+
+**Mutual Exclusivity**: Cannot be used with `--incoming-pr` flag
+
+### `--ai-summarize`
+
+Enable AI-enhanced summaries using Fabric integration.
+
+**Usage**: `./generate_changelog --incoming-pr 1672 --ai-summarize`
+
+### `--push`
+
+Enable automatic git push after creating an incoming entry. By default, the commit is created locally but not pushed to the remote repository.
+
+**Usage**: `./generate_changelog --incoming-pr 1672 --push`
+
+**Note**: When using `--push`, ensure you have proper authentication configured (SSH keys or GITHUB_TOKEN environment variable).
+
+## Troubleshooting
+
+### "PR is not open"
+
+Your PR has been closed or merged. Only open PRs can be processed.
+
+### "PR is not mergeable"
+
+Your PR has merge conflicts or other issues preventing it from being merged. Resolve conflicts and ensure the PR is in a mergeable state.
+
+### "Working directory is not clean"
+
+You have uncommitted changes. Commit or stash them before running the tool.
+
+### "Failed to fetch PR"
+
+Check your GitHub token and network connection. Ensure the PR number exists.
+
+## CI/CD Integration
+
+The system automatically processes all incoming PR files during the release workflow. No manual intervention is required.
+
+When a release is created:
+
+1. All `incoming/*.txt` files are aggregated using `--process-prs`
+2. Version is detected from `version.nix` or latest git tag
+3. A new version entry is created in CHANGELOG.md
+4. Incoming files are cleaned up (removed)
+5. Changes are staged for the release commit (CHANGELOG.md and cache file)
+
+## Best Practices
+
+1. **Run early**: Generate your changelog entry as soon as your PR is ready for review
+2. **Review content**: Always review the generated entry and edit if necessary
+3. **Keep it updated**: If you make significant changes to your PR, regenerate the entry
+4. **Use AI summaries**: Enable `--ai-summarize` for more professional, consistent formatting
+
+## Advanced Usage
+
+### Custom GitHub Token
+
+```bash
+./generate_changelog --incoming-pr 1672 --token YOUR_GITHUB_TOKEN
+```
+
+### Custom Repository Path
+
+```bash
+./generate_changelog --incoming-pr 1672 --repo /path/to/repo
+```
+
+### Disable Caching
+
+```bash
+./generate_changelog --incoming-pr 1672 --no-cache
+```
+
+### Enable Auto-Push
+
+```bash
+./generate_changelog --incoming-pr 1672 --push
+```
+
+This creates the commit locally and pushes it to the remote repository. By default, commits are only created locally, allowing you to review changes before pushing manually.
+
+**Authentication**: The tool automatically detects GitHub repositories and uses the GITHUB_TOKEN environment variable for authentication when pushing. For SSH repositories, ensure your SSH keys are properly configured.
+
+## Integration with Existing Workflow
+
+This system is fully backward compatible. The existing changelog generation continues to work unchanged. The new features are opt-in and only activated when using the new flags.
+
+## Support
+
+If you encounter issues:
+
+1. Check this documentation
+2. Verify your GitHub token has appropriate permissions
+3. Ensure your PR meets the validation requirements
+4. Check the tool's help: `./generate_changelog --help`
+
+For bugs or feature requests, please create an issue in the repository.

+# 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.

+# Shell Completions for Fabric
+
+Fabric comes with shell completion support for Zsh, Bash, and Fish shells. These completions provide intelligent tab-completion for commands, flags, patterns, models, contexts, and more.
+
+## Quick Setup (Automated)
+
+You can install completions without cloning the repo:
+
+```bash
+# No-clone install (Zsh/Bash/Fish supported)
+curl -fsSL https://raw.githubusercontent.com/danielmiessler/Fabric/refs/heads/main/completions/setup-completions.sh | sh
+
+# Optional: dry-run first
+curl -fsSL https://raw.githubusercontent.com/danielmiessler/Fabric/refs/heads/main/completions/setup-completions.sh | sh -s -- --dry-run
+
+# Optional: override the download source
+FABRIC_COMPLETIONS_BASE_URL="https://raw.githubusercontent.com/danielmiessler/Fabric/refs/heads/main/completions" \
+   sh -c "$(curl -fsSL https://raw.githubusercontent.com/danielmiessler/Fabric/refs/heads/main/completions/setup-completions.sh)"
+```
+
+Or, if you have the repository locally:
+
+```bash
+# Run the automated setup script from a cloned repo
+./completions/setup-completions.sh
+
+# Or see what it would do first
+./completions/setup-completions.sh --dry-run
+```
+
+The script will:
+
+- Detect whether you have `fabric` or `fabric-ai` installed
+- Detect your current shell (zsh, bash, or fish)
+- Use your existing `$fpath` directories (for zsh) or standard completion directories
+- Install the completion file with the correct name
+- Provide instructions for enabling the completions
+
+If the completion files aren't present locally (e.g., when running via `curl`), the script will automatically download them from GitHub.
+
+For manual installation or troubleshooting, see the detailed instructions below.
+
+## Manual Installation
+
+### Zsh
+
+1. Copy the completion file to a directory in your `$fpath`:
+
+   ```bash
+   sudo cp completions/_fabric /usr/local/share/zsh/site-functions/
+   ```
+
+2. **Important**: If you installed fabric as `fabric-ai`, create a symlink so completions work:
+
+   ```bash
+   sudo ln -s /usr/local/share/zsh/site-functions/_fabric /usr/local/share/zsh/site-functions/_fabric-ai
+   ```
+
+3. Restart your shell or reload completions:
+
+   ```bash
+   autoload -U compinit && compinit
+   ```
+
+### Bash
+
+1. Copy the completion file to a standard completion directory:
+
+   ```bash
+   # System-wide installation
+   sudo cp completions/fabric.bash /etc/bash_completion.d/
+
+   # Or user-specific installation
+   mkdir -p ~/.local/share/bash-completion/completions/
+   cp completions/fabric.bash ~/.local/share/bash-completion/completions/fabric
+   ```
+
+2. **Important**: If you installed fabric as `fabric-ai`, create a symlink:
+
+   ```bash
+   # For system-wide installation
+   sudo ln -s /etc/bash_completion.d/fabric.bash /etc/bash_completion.d/fabric-ai.bash
+
+   # Or for user-specific installation
+   ln -s ~/.local/share/bash-completion/completions/fabric ~/.local/share/bash-completion/completions/fabric-ai
+   ```
+
+3. Restart your shell or source the completion:
+
+   ```bash
+   source ~/.bashrc
+   ```
+
+### Fish
+
+1. Copy the completion file to Fish's completion directory:
+
+   ```bash
+   mkdir -p ~/.config/fish/completions
+   cp completions/fabric.fish ~/.config/fish/completions/
+   ```
+
+2. **Important**: If you installed fabric as `fabric-ai`, create a symlink:
+
+   ```bash
+   ln -s ~/.config/fish/completions/fabric.fish ~/.config/fish/completions/fabric-ai.fish
+   ```
+
+3. Fish will automatically load the completions (no restart needed).
+
+## Features
+
+The completions provide intelligent suggestions for:
+
+- **Patterns**: Tab-complete available patterns with `-p` or `--pattern`
+- **Models**: Tab-complete available models with `-m` or `--model`
+- **Contexts**: Tab-complete contexts for context-related flags
+- **Sessions**: Tab-complete sessions for session-related flags
+- **Strategies**: Tab-complete available strategies
+- **Extensions**: Tab-complete registered extensions
+- **Gemini Voices**: Tab-complete TTS voices for `--voice`
+- **File paths**: Smart file completion for attachment, output, and config options
+- **Flag completion**: All available command-line flags and options
+
+## Alternative Installation Method
+
+You can also source the completion files directly in your shell's configuration file:
+
+- **Zsh**: Add to `~/.zshrc`: `source /path/to/fabric/completions/_fabric`
+- **Bash**: Add to `~/.bashrc`: `source /path/to/fabric/completions/fabric.bash`
+- **Fish**: The file-based installation method above is preferred for Fish
+
+## Troubleshooting
+
+- If completions don't work, ensure the completion files have proper permissions
+- For Zsh, verify that the completion directory is in your `$fpath`
+- If you renamed the fabric binary, make sure to create the appropriate symlinks as described above
+- Restart your shell after installation to ensure completions are loaded
+
+The completion system dynamically queries the fabric command for current patterns, models, and other resources, so your completions will always be up-to-date with your fabric installation.

+```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

+
+# 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="--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

+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern create_study_notes
+
+# Extract key concepts and definitions
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" --pattern extract_concepts
+```
+
+### Meeting/Conference Processing
+
+```bash
+# Summarize conference talks with timestamps
+fabric -y "https://www.youtube.com/watch?v=VIDEO_ID" \
+  --transcript-with-timestamps \
+  --pattern meeting_summary
+
+# 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
+```
+
+For more patterns and advanced usage, see the main [Fabric documentation](../README.md).

+# 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.

-pbpaste | fabric --pattern summarize
-```
+    ```bash
+    pbpaste | fabric --pattern summarize
+    ```
 
 2. Run the `analyze_claims` Pattern with the `--stream` option to get immediate and streaming results.
 
-```bash
-pbpaste | fabric --stream --pattern analyze_claims
-```
+    ```bash
+    pbpaste | fabric --stream --pattern analyze_claims
+    ```
 
 3. Run the `extract_wisdom` Pattern with the `--stream` option to get immediate and streaming results from any Youtube video (much like in the original introduction video).
 
-```bash
-fabric -y "https://youtube.com/watch?v=uXs-zPc63kM" --stream --pattern extract_wisdom
-```
+    ```bash
+    fabric -y "https://youtube.com/watch?v=uXs-zPc63kM" --stream --pattern extract_wisdom
