Setting Up the Environment

Prerequisites

Before setting up CICADA, ensure you have the following installed:

• Python 3.10+
• Conda or pip (for dependency management)

Installation Steps (Quick Start)

# activate your venv or conda env first
pip install cicada-agent

CodeCAD Modules

pip install cicada-agent[codecad]

Installation Steps (For Developers)

1. Clone the Repository

git clone https://github.com/Oaklight/cicada.git
cd cicada

2. Install Dependencies

Always recommend to use conda or other tool to make an exclusive dev environment for CICADA

conda env create -f environment.yml
conda activate cicada

Then install local repo as pip package, remember you need to have [all] to build docs

pip install -e . # for just `core` features
pip install -e .[codecad] # for codecad related
pip install -e .[all] # for everything here

3. Update API Keys

The provided API keys in the config files are deprecated. Update the api_key and api_base_url in config.yaml or config/*.yaml in each module:

  Options:
  --force-rebuild: Force rebuild the database.
  --interactive: Run in interactive mode to ask multiple questions.
  --metric {l2,cosine}: Distance metric to use for similarity search.
  --query QUERY: Query text to search in the database.
  --debug: Enable debug mode for detailed logging.

  Examples:
  Interactive mode:

  python retrieval/tools/build123d_retriever.py --interactive
  

  Single query:

  python retrieval/tools/build123d_retriever.py --query "How to extrude a shape?"
  

workflow

• codecad_agent.py: Orchestrates the automation workflows for CAD design.
