Open source

Harness 0.1

Open source work on harness engineering, released in the open as it ships.

  • What it is

    Open source tooling for harness engineering: the tests, tools and guardrails wrapped around an AI agent so its work is checked before it ships.

  • Status

    Version 0.1 is in preparation. This page is the home for every release, with notes on what changed and why.

  • Why open

    The practices behind our client builds are better when others can read, run and break them.

Next stop: a 30-minute call.

Tell us what you are building. A senior lead will tell you honestly what it takes to ship it and take it to market.
