GitOfThoughts Stores an Agent's Reasoning as a Git Repo — and Finds Agent Memory Mostly Doesn't Pay

arXiv·medium signal

A June 12 arXiv paper (2606.14470) models an agent's reasoning tree as a git repository — thoughts are commits, scores are notes, outcomes are tags — making reasoning replayable, auditable, and mergeable across agents at near-zero engineering cost. Its counterintuitive headline result: across five memory formats (none, markdown, vector, graph, git) on two benchmarks, memory only helps above a 'copyability threshold' where the retrieved case is a near-duplicate (similarity >~0.8) of the current problem; below it, accuracy gains vanish. The takeaway for builders pouring effort into agent memory: git's real value is provenance and auditability, not accuracy.
