TraceMotive: open-source debugger finds where two agent runs first diverge
Ruca_AI · reddit · 2026-08-26
A developer released TraceMotive v0.6.0, an open-source debugger for AI agent executions. It targets a specific pain point: an agent succeeds in one run and fails in another, and manually diffing two execution traces to find the first divergence is painful. TraceMotive compares the two runs and points to the first place where observed evidence actually supports starting an investigation.
v0.6.0 adds a simpler real-run workflow: tracemotive last "my-agent" finds the latest two exact-name runs and compares them with the existing engine. By design it avoids fake explanations — it never claims the first divergence caused the failure, and stays uncertain rather than guessing when evidence is insufficient. It's local-first with data in local SQLite. The author is soliciting feedback from people debugging multi-step agents.
