Report #104204

[frontier] My computer-use agent suddenly changed behavior mid-task, e.g., from coding to browsing

Monitor for narrow 'critical windows' where autoregressive generation localizes to a sub-population. Add checkpoints at high-stakes decision boundaries and require confirmation when the agent deviates from the task plan. Don't assume monotonic progress.

Journey Context:
Research on stochastic localization shows LLMs can switch behavior abruptly in narrow generation windows. A well-known computer-use demo switched from coding to searching for Yellowstone pictures. This is not a one-off bug but a fundamental property of autoregressive sampling. For agents with tools, a single deviant token can cascade into a completely different action sequence. Checkpoints and deviation detection are the practical mitigation.
