# AI Crew for Reviewing Markdown Syntax
## Introduction This project is an example using the CrewAI framework to automate the process reviewing a markdown file for syntax issues. A general assistant leverages a custom tool to get a list of markdown linting errors. It then summarizes those errors into a list of changes to make to the document.
## Running the Script This example uses the OpenAI API to call a model. This can be through a locally hosted solution like LM Studio, or the Open AI API endpoint with your API key.
======= - **Configure Environment**: Rename `.env.example` to `.env` and set up the environment variables the model, endpoint url, and api key. - **Install Dependencies**: Run `poetry install --no-root`. - **Execute the Script**: Run `python main.py README.md` to see a list of recommended changes to this document.
## Details & Explanation - **Running the Script**: Execute `python main.py <path to markdown file>`. The script will leverage the CrewAI framework to process the specified file and return a list of changes.
## License This project is released under the MIT License.
