TaskWeaver

TaskWeaver is Microsoft's open-source "code-first" agent framework for seamlessly planning and executing data analytics tasks. Instead of relying on static tool plugins, it translates user requests into complete, stateful Python code snippets — naturally handling rich data structures like pandas DataFrames, numpy arrays, and tensors. A Planner agent creates high-level task roadmaps while a Code Interpreter agent generates and executes Python code, with both chat history and code-execution history (including in-memory data) preserved across turns.

It supports custom Python plugins with rich type annotations for enterprise databases, code verification before execution, Docker container-mode execution, shared memory between roles, and vision input for the Planner. The repo has around 6,100 GitHub stars and is MIT licensed. Honest limitations: it requires Python expertise to set up and extend, is focused on data analytics rather than general-purpose agency, and documentation can be sparse for advanced scenarios.
