Overview

OSA (Open-Source-Advisor) is a LLM-based tool for improving the quality of scientific open source projects and helping create them from scratch. It automates the generation of README, different levels of documentation, CI/CD scripts, etc. It also generates advices and recommendations for the repository.

OSA is currently under development, so not all features are implemented.

Core features

1. README file generation: Automates the creation of a clear and structured README file for a repository, including projects based on research papers.

2. Documentation generation: Automatically generates docstrings for Python code.

3. Automatic implementation of changes: Clones the repository, creates a branch, commits and pushes changes, and creates a pull request with proposed changes.

4. Various LLMs: Use OSA with an LLM accessible via API (e.g., OpenAI, VseGPT, Ollama), a local server, or try an osa_bot hosted on ITMO servers.

5. Workflow Generator: Automatically generates customizable CI/CD workflows for Python repositories, including unit tests, code formatting, PEP 8 compliance checks, and PyPI publication.

Installation

Install Open-Source-Advisor using one of the following methods:

Using PyPi:

pip install osa_tool

Build from source:

1. Clone the Open-Source-Advisor repository:

git clone https://github.com/aimclub/OSA

2. Navigate to the project directory:

cd Open-Source-Advisor

3. Install the project dependencies:

Using pip  

pip install -r requirements.txt

Using poetry  

poetry install 

Using docker  

docker build --build-arg GIT_USER_NAME="your-user-name" --build-arg GIT_USER_EMAIL="your-user-email" -f docker/Dockerfile -t {image-name} .

Getting started

Prerequisites

OSA requires Python 3.10 or higher.

The .env file is required to specify the LLM API key (OPENAI_API_KEY or AUTHORIZATION_KEY) and optionally a Git token. The Git token (GIT_TOKEN) may be omitted if you plan to work with a public repository without creating a fork (using the --no-fork option).

Alternatively, instead of GIT_TOKEN, you can use GITHUB_TOKEN, GITLAB_TOKEN, or GITVERSE_TOKEN for GitHub, GitLab, and Gitverse respectively.

When running osa-tool from CLI, you need to set the GIT_TOKEN and API key first:

# Linux / macOS (bash/zsh)
export OPENAI_API_KEY=<your_api_key>
export GIT_TOKEN=<your_git_token>

# Windows (PowerShell)
setx OPENAI_API_KEY "<your_api_key>"
setx GIT_TOKEN "<your_git_token>"

Tokens

Token name	Description	Mandatory
GIT_TOKEN	Personal GitHub/GitLab/Gitverse token used to clone private repositories, access metadata, and interact with its API.	Yes
OPENAI_API_KEY	API key for accessing OpenAI, vsegpt and openrouter providers	No
AUTHORIZATION_KEY	API key for gigachat provider	No
X-API-Key	API key for the pepy.tech REST API, used to fetch Python package download statistics	No

Usage

Run Open-Source-Advisor using the following command:

Using pip  

python -m osa_tool.run -r {repository} [--api {api}] [--base-url {base_url}] [--model {model_name}] [--attachment {article}] [--convert-notebooks {notebook_paths}]

Using docker  

docker run --env-file .env {image-name} -r {repository} [--api {api}] [--base-url {base_url}] [--model {model_name}] [--attachment {article}] [--convert-notebooks {notebook_paths}]

The --attachment option enables you to choose a README template for a repository based on an article. You can provide either a link to a PDF file of the article or a path to a local PDF file after the --attachment option. If you are using Docker, ensure that you upload the PDF file to the OSA folder before building the image, then, specify the path as /app/OSA/... or just use volume mounting to access the file.

The --generate-workflows option is intended to create customizable CI/CD pipelines for Python repositories. For detailed documentation, see the Workflow Generator README.

Configuration

Flag	Description	Default
-r, --repository	URL of the GitHub/GitLab/Gitverse repository (Mandatory)
-b, --branch	Branch name of the repository	Default branch
-o, --output	Path to the output directory	Current working directory
--api	LLM API service provider	itmo
--base-url	URL of the provider compatible with API OpenAI	https://api.openai.com/v1
--model	Specific LLM model to use	gpt-3.5-turbo
--top_p	Nucleus sampling probability	None
--temperature	Sampling temperature to use for the LLM output (0 = deterministic, 1 = creative).	None
--max_tokens	Maximum number of tokens the model can generate in a single response	None
--attachment	Path to a local PDF or .docx file, or a URL to a PDF resource	None
-m, --mode	Operation mode for repository processing: basic, auto (default), or advanced.	auto
--delete-dir	Enable deleting the downloaded repository after processing	disabled
--no-fork	Avoid create fork for target repository	False
--no-pull-request	Avoid create pull request for target repository	False

Examples

Examples of generated README files are available in examples.

URL of the GitHub/GitLab/Gitverse repository, LLM API service provider (optional) and Specific LLM model to use (optional) are required to use the generator.

Supported LLM providers are available as part of the ProtoLLM ecosystem. See the connectors directory for the full list.

Local ITMO model:

python -m osa_tool.run -r https://github.com/aimclub/OSA --base-url [ITMO_MODEL_URL]

For this API provider itmo model url must be specified in dotenv (ITMO_MODEL_URL=) or in the --base-url argument.

OpenAI:

python -m osa_tool.run -r https://github.com/aimclub/OSA --api openai

VseGPT:

python -m osa_tool.run -r https://github.com/aimclub/OSA --api openai --base-url https://api.vsegpt.ru/v1 --model openai/gpt-3.5-turbo

Openrouter:

python -m osa_tool.run -r https://github.com/aimclub/OSA --api openai --base-url https://openrouter.ai/api/v1 --model qwen/qwen3-30b-a3b-instruct-2507

Ollama:

python -m osa_tool.run -r https://github.com/aimclub/OSA --api ollama --base-url http://[YOUR_OLLAMA_IP]:11434 --model gemma3:27b
