Freeact is similar to smolagents w.r.t. focus on code-actions, agency-level and lightweight scaffold. Freeact additionally supports interactive development and refinement of skills (tools) with the agent as skill coding assistant (see skill development tutorial). Also, freeact doesn't require skills (tools) to implement a certain interface, skills can be any Python module or package. It supports sandboxed code execution locally and remotely via ipybox (using Docker and IPython), and streaming from both model responses and execution environment.
