BMAD™'s natural language framework works in ANY domain. Expansion packs provide specialized AI agents for creative writing, business strategy, health & wellness, education, and more. Also expansion packs can expand the core BMAD-METHOD™ with specific functionality that is not generic for all cases. [See the Expansion Packs Guide](docs/expansion-packs.md) and learn to create your own!

## Codebase Flattener Tool
|
||||
|
||||
The BMAD-METHOD™ includes a powerful codebase flattener tool designed to prepare your project files for AI model consumption. This tool aggregates your entire codebase into a single XML file, making it easy to share your project context with AI assistants for analysis, debugging, or development assistance.
|
||||
|
||||
### Features
|
||||
|
||||
- **AI-Optimized Output**: Generates clean XML format specifically designed for AI model consumption
|
||||
- **Smart Filtering**: Automatically respects `.gitignore` patterns to exclude unnecessary files, plus optional project-level `.bmad-flattenignore` for additional exclusions
|
||||
- **Binary File Detection**: Intelligently identifies and excludes binary files, focusing on source code
|
||||
- **Progress Tracking**: Real-time progress indicators and comprehensive completion statistics
|
||||
- **Flexible Output**: Customizable output file location and naming
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Basic usage - creates flattened-codebase.xml in current directory
|
||||
npx bmad-method flatten
|
||||
|
||||
# Specify custom input directory
|
||||
npx bmad-method flatten --input /path/to/source/directory
|
||||
npx bmad-method flatten -i /path/to/source/directory
|
||||
|
||||
# Specify custom output file
|
||||
npx bmad-method flatten --output my-project.xml
|
||||
npx bmad-method flatten -o /path/to/output/codebase.xml
|
||||
|
||||
# Combine input and output options
|
||||
npx bmad-method flatten --input /path/to/source --output /path/to/output/codebase.xml
|
||||
```
|
||||
|
||||
### Example Output
|
||||
|
||||
The tool will display progress and provide a comprehensive summary:
|
||||
|
||||
```text
|
||||
📊 Completion Summary:
|
||||
✅ Successfully processed 156 files into flattened-codebase.xml
|
||||
📁 Output file: /path/to/your/project/flattened-codebase.xml
|
||||
📏 Total source size: 2.3 MB
|
||||
📄 Generated XML size: 2.1 MB
|
||||
📝 Total lines of code: 15,847
|
||||
🔢 Estimated tokens: 542,891
|
||||
📊 File breakdown: 142 text, 14 binary, 0 errors
|
||||
```
|
||||
|
||||
The generated XML file contains your project's text-based source files in a structured format that AI models can easily parse and understand, making it perfect for code reviews, architecture discussions, or getting AI assistance with your BMAD-METHOD™ projects.
|
||||
|
||||
#### Advanced Usage & Options
|
||||
|
||||
- CLI options
|
||||
- `-i, --input <path>`: Directory to flatten. Default: current working directory or auto-detected project root when run interactively.
|
||||
- `-o, --output <path>`: Output file path. Default: `flattened-codebase.xml` in the chosen directory.
|
||||
- Interactive mode
|
||||
- If you do not pass `--input` and `--output` and the terminal is interactive (TTY), the tool will attempt to detect your project root (by looking for markers like `.git`, `package.json`, etc.) and prompt you to confirm or override the paths.
|
||||
- In non-interactive contexts (e.g., CI), it will prefer the detected root silently; otherwise it falls back to the current directory and default filename.
|
||||
- File discovery and ignoring
|
||||
- Uses `git ls-files` when inside a git repository for speed and correctness; otherwise falls back to a glob-based scan.
|
||||
- Applies your `.gitignore` plus a curated set of default ignore patterns (e.g., `node_modules`, build outputs, caches, logs, IDE folders, lockfiles, large media/binaries, `.env*`, and previously generated XML outputs).
|
||||
- Supports an optional `.bmad-flattenignore` file at the project root for additional ignore patterns (gitignore-style). If present, its rules are applied after `.gitignore` and the defaults.
|
||||
|
||||
##### `.bmad-flattenignore` example
|
||||
|
||||
Create a `.bmad-flattenignore` file in the root of your project to exclude files that must remain in git but should not be included in the flattened XML:
|
||||
|
||||
```text
|
||||
seeds/**
|
||||
scripts/private/**
|
||||
**/*.snap
|
||||
```
|
||||
|
||||
- Binary handling
|
||||
- Binary files are detected and excluded from the XML content. They are counted in the final summary but not embedded in the output.
|
||||
- XML format and safety
|
||||
- UTF-8 encoded file with root element `<files>`.
|
||||
- Each text file is emitted as a `<file path="relative/path">` element whose content is wrapped in `<![CDATA[ ... ]]>`.
|
||||
- The tool safely handles occurrences of `]]>` inside content by splitting the CDATA to preserve correctness.
|
||||
- File contents are preserved as-is and indented for readability inside the XML.
|
||||
- Performance
|
||||
- Concurrency is selected automatically based on your CPU and workload size. No configuration required.
|
||||
- Running inside a git repo improves discovery performance.
|
||||
|
||||
#### Minimal XML example
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<files>
|
||||
<file path="src/index.js"><![CDATA[
|
||||
// your source content
|
||||
]]></file>
|
||||
</files>
|
||||
```
