JoshPurtell · x · 2026-11-07

In a discussion about agent monitoring tools, JoshPurtell recommends Temper by @nerdsane: he's used it to have agents build state machines for monitoring processes, reporting that it works smoothly and enables powerful experiences like custom progress bars and streaming log info.

Temper's GitHub repo describes it as "a machine tool for agents: a verified runtime for systems agents build," dual-licensed Apache-2.0/MIT, with 113 stars and 20 forks.
