Build focused AI agents without framework sprawl
4.8(6)1Development ToolsOpen Source
ThinHarness is a minimal, opinionated Python harness for purpose-built agents.
It owns the focused set of primitives that are tedious to rebuild and leaves the rest of the stack to your app.
It matches the harness-level feature coverage of frameworks 5–10× its size, so forking is a real option, not a theoretical one.

1I started building ThinHarness after getting tired with huge agent frameworks. I usually needed only a small slice of functionality, but that slice came with coupled assumptions that didn't match my application. I've been using it for all my agent projects recently but would love feedback from anyone building agent workflows in Python!
