📦 Repomix (Python Version)

English | 简体中文

🎯 1. Introduction

Repomix is a powerful tool that packs your entire repository into a single, AI-friendly file. It's perfect for when you need to feed your codebase to Large Language Models (LLMs) or other AI tools like Claude, ChatGPT, and Gemini.

The original Repomix is written in JavaScript, and this is the ported Python version.

⭐ 2. Features

• AI-Optimized: Formats your codebase in a way that's easy for AI to understand and process.
• Token Counting: Provides token counts for each file and the entire repository using tiktoken, with configurable encoding (--token-count-encoding).
• Simple to Use: Pack your entire repository with just one command.
• Multiple Directories: Process multiple directories in a single command (repomix src lib tests).
• Customizable: Easily configure what to include or exclude.
• Git-Aware: Automatically respects your .gitignore, .repomixignore, and .ignore files.
• Security-Focused: Built-in security checks to detect and prevent the inclusion of sensitive information (powered by detect-secrets).
• Code Compression: Advanced code compression with multiple modes to reduce output size while preserving essential information.
• Semantic CLI Suggestions: Unknown CLI options suggest the closest valid alternative (e.g., --exclude → "Did you mean: --ignore?").
• Quiet Mode: Suppress all console output except errors with --quiet.
• ⚡ Performance: Utilizes multiprocessing or threading for faster analysis on multi-core systems.
• ⚙️ Encoding Aware: Automatically detects and handles various file encodings (using chardet) beyond UTF-8, increasing robustness.

🚀 3. Quick Start

Quick Run with uvx (Recommended)

The easiest way to use Repomix is with uvx - no installation required:

uvx repomix

That's it! This will pack your current directory into an AI-friendly file.

More examples:

# Pack with JSON output
uvx repomix --style json

# Pack a remote repository
uvx repomix --remote https://github.com/username/repo

# Pack with specific patterns
uvx repomix --include "src/**/*.py" --ignore "tests/**"

# Use a specific version
uvx repomix@0.5.0

You can also use pipx: pipx run repomix

Install with pip

For frequent usage, you can install Repomix globally:

pip install repomix

Then run in any project directory:

repomix

Docker Usage

You can also use Repomix with Docker without installing it locally:

# Build the Docker image
docker build -t repomix .

# Run repomix on the current directory
docker run --rm -v "$(pwd)":/app repomix

# Run repomix with specific options
docker run --rm -v "$(pwd)":/app repomix --style markdown --output custom-output.md

# Run repomix on a different directory
docker run --rm -v "/path/to/your/project":/app repomix

Docker Benefits:

• Isolated Environment: Run repomix without installing Python dependencies on your host system
• Consistent Results: Ensures the same environment across different machines
• Easy Distribution: Share the exact repomix version and configuration with your team
• No Installation Required: Use repomix immediately without pip install

That's it! Repomix will generate a repomix-output.md file (by default) in your current directory, containing your entire repository in an AI-friendly format.

📖 4. Usage

4.1 Command Line Usage

To pack your entire repository:

repomix

To pack a specific directory:

repomix path/to/directory

To pack multiple directories at once:

repomix src lib tests

To pack a remote repository:

repomix --remote https://github.com/username/repo

To pack a specific branch of a remote repository:

repomix --remote https://github.com/username/repo --remote-branch feature-branch

To initialize a new configuration file:

repomix --init
# Use --global to create a global configuration file (see Configuration Options below)
repomix --init --global

4.2 Configuration Options

Create a repomix.config.json file in your project root for custom configurations. Repomix also automatically loads a global configuration file if it exists (e.g., ~/.config/repomix/repomix.config.json on Linux), merging it with lower priority than local config and CLI options.

[!NOTE] Note on remove_comments: This feature is language-aware, correctly handling comment syntax for various languages rather than using a simple generic pattern. Supported languages: Python, JavaScript, TypeScript, JSX, TSX, Vue, Svelte, Java, C, C++, C#, Go, Rust, Ruby, PHP, Swift, Kotlin, HTML, CSS, XML, YAML

Remote Repository Configuration

The remote section allows you to configure remote repository processing:

• url: The URL of the remote Git repository to process
• branch: The specific branch, tag, or commit hash to process (optional, defaults to repository's default branch)

When a remote URL is specified in the configuration, Repomix will process the remote repository instead of the local directory. This can be overridden by CLI parameters (--remote-branch).

You can use various URL formats with --remote:

# GitHub shorthand
repomix --remote user/repo

# Full GitHub URL
repomix --remote https://github.com/user/repo

# Specific branch
repomix --remote https://github.com/user/repo --remote-branch feature-branch

# Specific tag
repomix --remote https://github.com/user/repo --remote-branch v1.0.0

# Specific commit
repomix --remote https://github.com/user/repo --remote-branch abc123

4.3 Security Check

Repomix includes built-in security checks using the detect-secrets library to detect potentially sensitive information (API keys, credentials, etc.). By default (exclude_suspicious_files: true), detected files are excluded from the output.

Disable checks via configuration or CLI:

repomix --no-security-check

4.4 Custom Instructions

You can add custom instructions to the output file that will guide AI tools on how to interpret and use the packed codebase.

Create a markdown file (e.g., repomix-instruction.md) with your instructions:

## Project Context
This is a Python web application using FastAPI.
Please follow PEP 8 conventions when suggesting code changes.

Then specify the path via CLI or configuration:

# Via CLI
repomix --instruction-file-path repomix-instruction.md

# Via configuration (repomix.config.json)

{
  "output": {
    "instruction_file_path": "repomix-instruction.md"
  }
}

The instruction content will be included in the "Instruction" section of the output file.

4.5 Token Count

Repomix provides token counting to help you understand the size of your codebase in terms of AI model tokens.

Choosing an Encoding

Use --token-count-encoding to select the tokenizer encoding:

# Use GPT-4o encoding (default)
repomix --token-count-encoding o200k_base

# Use GPT-3.5/4 encoding
repomix --token-count-encoding cl100k_base

Visualizing Token Distribution

Use --token-count-tree to display a file tree with token counts for each file:

# Show all files with token counts
repomix --token-count-tree

# Show only files with 100 or more tokens
repomix --token-count-tree 100

4.6 Splitting Output for Large Codebases

For large codebases that exceed AI model context limits, you can split the output into multiple files:

# Split into files of approximately 500KB each
repomix --split-output 500kb

# Split into files of approximately 2MB each
repomix --split-output 2mb

Output files will be numbered sequentially (e.g., repomix-output.1.md, repomix-output.2.md, etc.). Files are split at directory boundaries to keep related files together.

4.7 Agent Skills Generation

Repomix can generate Claude Agent Skills format output, which provides structured reference materials for AI coding agents.

# Generate skills with auto-detected name
repomix --skill-generate

# Generate skills with a custom name
repomix --skill-generate my-project

# Specify output directory directly
repomix --skill-output ./my-skills-dir

This creates the following directory structure:

.claude/skills/<name>/
├── SKILL.md                          # Entry point with usage guide
└── references/
    ├── summary.md                    # Purpose, format, and statistics
    ├── project-structure.md          # Directory tree with line counts
    ├── files.md                      # All file contents
    └── tech-stack.md                 # Languages, frameworks, dependencies

4.8 Code Compression

Repomix provides advanced code compression capabilities to reduce output size while preserving essential information. This feature is particularly useful when working with large codebases or when you need to focus on specific aspects of your code.

4.8.1 Compression Modes

Interface Mode (keep_interfaces: true)

• Preserves function and class signatures with their complete type annotations
• Keeps all docstrings for comprehensive API documentation
• Removes implementation details, replacing them with pass statements
• Perfect for generating API documentation or understanding code structure

Signature Mode (keep_signatures: true, keep_interfaces: false)

• Preserves function and class definitions
• Optionally keeps docstrings based on keep_docstrings setting
• Maintains full implementation code
• Useful for standard code compression while keeping functionality

Minimal Mode (keep_signatures: false)

• Removes all function and class definitions
• Keeps only global variables, imports, and module-level code
• Maximum compression for focusing on configuration and constants

4.8.2 Configuration Options

{
  "compression": {
    "enabled": false,           // Enable/disable compression
    "keep_signatures": true,    // Keep function/class signatures
    "keep_docstrings": true,    // Keep docstrings
    "keep_interfaces": true     // Interface mode (signatures + docstrings only)
  }
}

4.8.3 Usage Examples

Generate API Documentation:

# Create interface-only output for API documentation
repomix --config-override '{"compression": {"enabled": true, "keep_interfaces": true}}'

Compress Implementation Details:

# Keep signatures but remove implementation for code overview
repomix --config-override '{"compression": {"enabled": true, "keep_interfaces": false, "keep_signatures": true, "keep_docstrings": false}}'

Extract Configuration Only:

# Keep only global variables and constants
repomix --config-override '{"compression": {"enabled": true, "keep_signatures": false}}'

4.8.4 Language Support

Currently, advanced compression features are fully supported for:

• Python: Complete AST-based compression with all modes
• JavaScript/TypeScript: Tree-sitter based compression
• Go: Tree-sitter based compression
• Java: Tree-sitter based compression
• C/C++: Tree-sitter based compression
• C#: Tree-sitter based compression
• Rust: Tree-sitter based compression
• Ruby: Tree-sitter based compression
• PHP: Tree-sitter based compression
• Swift: Tree-sitter based compression
• CSS: Tree-sitter based compression
• Other Languages: Basic compression with warnings (future enhancement planned)

4.8.5 Example Output

Original Python Code:

def calculate_sum(a: int, b: int) -> int:
    """
    Calculate the sum of two integers.
    
    Args:
        a: First integer
        b: Second integer
        
    Returns:
        The sum of a and b
    """
    if not isinstance(a, int) or not isinstance(b, int):
        raise TypeError("Both arguments must be integers")
    
    result = a + b
    print(f"Calculating {a} + {b} = {result}")
    return result

Interface Mode Output:

def calculate_sum(a: int, b: int) -> int:
    """
    Calculate the sum of two integers.
    
    Args:
        a: First integer
        b: Second integer
        
    Returns:
        The sum of a and b
    """
    pass

4.9 Ignore Patterns

Repomix provides multiple methods to set ignore patterns for excluding specific files or directories during the packing process:

Priority Order

Ignore patterns are applied in the following priority order (from highest to lowest):

1. Custom patterns in configuration file (ignore.custom_patterns)
2. .repomixignore file
3. .ignore file (if ignore.use_dot_ignore is true)
4. .gitignore file (if ignore.use_gitignore is true)
5. Default patterns (if ignore.use_default_ignore is true)

Ignore Methods

.gitignore

By default, Repomix uses patterns listed in your project's .gitignore file. This behavior can be controlled with the ignore.use_gitignore option in the configuration file:

{
  "ignore": {
    "use_gitignore": true
  }
}

Default Patterns

Repomix includes a default list of commonly excluded files and directories (e.g., __pycache__, .git, binary files). This feature can be controlled with the ignore.use_default_ignore option:

{
  "ignore": {
    "use_default_ignore": true
  }
}

The complete list of default ignore patterns can be found in default_ignore.py.

.repomixignore

You can create a .repomixignore file in your project root to define Repomix-specific ignore patterns. This file follows the same format as .gitignore.

.ignore

Repomix also supports .ignore files, which follow the same format as .gitignore. This is useful for tools that share a common ignore file. This behavior can be controlled with the ignore.use_dot_ignore option or the --no-dot-ignore CLI flag.

Custom Patterns

Additional ignore patterns can be specified using the ignore.custom_patterns option in the configuration file:

{
  "ignore": {
    "custom_patterns": [
      "*.log",
      "*.tmp",
      "tests/**/*.pyc"
    ]
  }
}

Notes

• Binary files are not included in the packed output by default, but their paths are listed in the "Repository Structure" section of the output file. This provides a complete overview of the repository structure while keeping the packed file efficient and text-based.
• Ignore patterns help optimize the size of the generated pack file by ensuring the exclusion of security-sensitive files and large binary files, while preventing the leakage of confidential information.
• All ignore patterns use glob pattern syntax similar to .gitignore.

🔒 5. Output File Format

Repomix generates a single file with clear separators between different parts of your codebase. To enhance AI comprehension, the output file begins with an AI-oriented explanation, making it easier for AI models to understand the context and structure of the packed repository.

5.1 Plain Text Format (default)

This file is a merged representation of the entire codebase, combining all repository files into a single document.

================================================================
File Summary
================================================================
(Metadata and usage AI instructions)

================================================================
Repository Structure
================================================================
src/
  cli/
    cliOutput.py
    index.py
  config/
    configLoader.py

(...remaining directories)

================================================================
Repository Files
================================================================

================
File: src/index.py
================
# File contents here

================
File: src/utils.py
================
# File contents here

(...remaining files)

================================================================
Statistics
================================================================
(File statistics and metadata)

5.2 Markdown Format

To generate output in Markdown format, use the --style markdown option:

python -m repomix --style markdown

The Markdown format structures the content in a readable manner:

# File Summary
(Metadata and usage AI instructions)

# Repository Structure
```
src/
  cli/
    cliOutput.py
    index.py
```

# Repository Files

## File: src/index.py
```python
# File contents here
```

## File: src/utils.py
```python
# File contents here
```

# Statistics
- Total Files: 19
- Total Characters: 37377
- Total Tokens: 11195

5.3 XML Format

To generate output in XML format, use the --style xml option:

python -m repomix --style xml

The XML format structures the content in a hierarchical manner:

<?xml version="1.0" encoding="UTF-8"?>
<repository>
<repository_structure>
(Directory and file structure)
</repository_structure>

<repository_files>
<file>
  <path>src/index.py</path>
  <stats>
    <chars>1234</chars>
    <tokens>567</tokens>
  </stats>
  <content>
    # File contents here
  </content>
</file>
(...remaining files)
</repository_files>

<statistics>
  <total_files>19</total_files>
  <total_chars>37377</total_chars>
  <total_tokens>11195</total_tokens>
</statistics>
</repository>

5.4 JSON Format

To generate output in JSON format, use the --style json option:

python -m repomix --style json

The JSON format provides machine-readable structured output:

{
  "summary": {
    "total_files": 19,
    "total_chars": 37377,
    "total_tokens": 11195,
    "generation_date": "2025-01-28T12:00:00"
  },
  "file_tree": {
    "src": {
      "index.py": "",
      "utils.py": ""
    }
  },
  "files": [
    {
      "path": "src/index.py",
      "content": "# File contents here",
      "chars": 1234,
      "tokens": 567
    }
  ]
}

JSON format is ideal for:

• Integration with other tools and scripts
• Programmatic processing of codebase analysis
• Building custom pipelines and workflows

You can use jq to extract specific information from the JSON output:

# Extract file paths
cat repomix-output.json | jq '.files[].path'

# Get total token count
cat repomix-output.json | jq '.summary.total_tokens'

# Find files with more than 1000 tokens
cat repomix-output.json | jq '.files[] | select(.tokens > 1000) | {path, tokens}'

7.2 MCP (Model Context Protocol) Server

Repomix can run as an MCP server, allowing AI assistants like Claude to directly interact with your codebase without manual file preparation.

📦 Installation Required: Before using MCP features, make sure you have installed repomix: pip install repomix

Starting the MCP Server

# Start the MCP server (detailed logs output to stderr)
repomix --mcp

After starting, you'll see logs like:

📦 Repomix v0.3.0

Configuring in AI Assistants

Claude Desktop Add to claude_desktop_config.json:

{
  "mcpServers": {
    "repomix": {
      "command": "repomix",
      "args": ["--mcp"],
      "cwd": "/path/to/your/project"
    }
  }
}

VS Code / Cline Add to cline_mcp_settings.json:

{
  "mcpServers": {
    "repomix": {
      "command": "repomix", 
      "args": ["--mcp"],
      "cwd": "/path/to/your/project"
    }
  }
}

Claude Code

# From any directory (after installing repomix)
claude mcp add repomix -- repomix --mcp

About the cwd Parameter

The cwd (current working directory) parameter in MCP configuration determines where the repomix command runs from. Here are the recommended settings:

• For general use: Set cwd to your home directory or any stable location like "/Users/yourusername" (macOS) or "/home/yourusername" (Linux)
• For specific projects: Set cwd to your main project directory that you frequently analyze
• For development: You can use any directory since repomix can process any path you specify in the tool calls

Examples:

// General use - works from anywhere
"cwd": "/Users/yourusername"

// Project-specific - convenient for frequent analysis  
"cwd": "/Users/yourusername/projects/my-main-project"

// Development - flexible starting point
"cwd": "/Users/yourusername/dev"

💡 Pro Tip: The MCP tools allow you to specify target directories in the tool parameters, so the cwd is just the starting location. You can analyze any accessible directory regardless of where the server starts.

7.3 Best Practices

• Be Specific: When prompting the AI, be as specific as possible about what you want. The more context you provide, the better the results will be.
• Iterate: Don't be afraid to iterate on your prompts. If you don't get the results you want on the first try, refine your prompt and try again.
• Combine with Manual Review: While AI can be a powerful tool, it's not perfect. Always combine AI-generated output with manual review and editing.
• Security First: Always be mindful of security when working with your codebase. Use Repomix's built-in security checks and avoid sharing sensitive information with AI tools.
