llm-project-summarizer 0.0.2

Generate LLM-friendly summaries of Python and Go codebases

LLM Project Summarizer

LLM Project Summarizer is a specialized command-line tool that transforms Python and Go codebases into concise, structured summaries optimized for Large Language Models. When working with LLMs like ChatGPT or Claude, sending entire codebases is often impractical due to context limitations. This tool solves that problem by generating intelligent summaries that capture the essential architecture, relationships, and patterns in your code while excluding implementation details.

The tool understands language-specific patterns – in Go, it recognizes packages, interfaces, and implementations; in Python, it comprehends modules, class hierarchies, and type annotations. The output is formatted in Markdown with Mermaid diagrams, making it ideal for LLM consumption and human readability.

Installation

Option 1: Install from PyPI

pip install llm-project-summarizer

Option 2: Install from GitHub

pip install git+https://github.com/MuhammadYossry/llm-project-summarizer.git

Option 3: Development Installation

# Clone the repository
git clone https://github.com/MuhammadYossry/llm-project-summarizer
cd llm-project-summarizer

# Install with poetry (recommended for development)
poetry install

# Or install with pip in editable mode
pip install -e .

Usage

Basic Usage

# Using pip installed version
project-summarizer /path/to/project

# Custom output file
project-summarizer /path/to/project -o custom_summary.md

# Exclude patterns
project-summarizer /path/to/project --exclude "vendor/*" --exclude "*.test.go"

Using Poetry

# Install and run using poetry
poetry install
poetry run project-summarizer /path/to/project

# Run with options
poetry run project-summarizer /path/to/project -o summary.md --exclude "vendor/*"

With Configuration File

Create .summarizer.yaml:

exclude:
  - "vendor/*"
  - "**/*_test.go"
  - "**/__pycache__"
output: "project_summary.md"

Use the config:

project-summarizer /path/to/project --config .summarizer.yaml

Command Line Options

project-summarizer --help

Options:
  --output, -o PATH    Output file path [default: project_summary.md]
  --exclude, -e TEXT   Exclusion patterns (can be used multiple times)
  --config, -c PATH    Path to config file
  --help              Show this message and exit

How It Works

The tool employs language-specific parsers to analyze source code. For Go, it uses pattern matching to identify packages, interfaces, and implementations. For Python, it utilizes the Abstract Syntax Tree (AST) to extract classes, functions, and their relationships. The parsed information is then organized into a hierarchical structure optimized for LLM understanding.
