Swival
A small, open-source Python CLI coding agent designed to work as well with local and small open models as with large hosted ones, with built-in note-taking, goal tracking and a review step.
Swival is a coding agent that treats local models (via LM Studio or similar) and online services through the same tool, without needing to change agents when switching models. It keeps working notes on what it has learned and what remains to be done so an interrupted session can resume, and a goal-setting option keeps it working toward a stated objective across a long task.
An optional review step has Swival check its own work and retry when problems are found, or hand review to a different model; a built-in security audit checks existing code for bugs. For hosted services, secret encryption can hide supported API keys and tokens before they reach the model, and filters can strip other private details such as customer names and internal URLs. It installs with uv tool install or Homebrew and is written in Python, so it can also run as part of a Python program.
