Pre-release

This release is a pre-release and may not be stable for production use.

vis-agent

Python SDK for Vis agent sessions and extensions.

pip install vis-agent

You need Python 3.12+ on Linux or macOS and a configured model provider. You do not have to install Vis first. A local run uses the installed vis-agent only when it is the same release as the SDK. Otherwise the SDK downloads only that release's engine into ~/.vis/sdk and checks it against the release checksums. Set VIS_NO_AUTO_INSTALL=1 to turn this off. To download the engine ahead of time, for example in a container image, run python -c "from blockether.vis.engine import install; print(install())".

Run a local agent

from blockether.vis.engine import Agent

with Agent(project=".") as agent:
    result = agent.run("Summarize this project without changing files.")
    print(result["status"])

The SDK starts a private Vis process with a temporary session database and removes both when the block ends. Tasks can incur provider charges and can change project files. To choose the executable or share one process between agents, use LocalEngine. See the stdio guide.

  • Python SDK guide — run a local agent, continue a conversation or connect to a shared gateway.
  • Python API reference — browse classes, methods, signatures and types generated from the SDK source.
  • Extension guide — add tools to Vis.
  • Decision models — download Laya or GLiNER2.5, train both heads offline, publish FP32 and select a version.
  • Documentation — browse all guides and reference pages.
