[frontier] Computer-using AI agents failing due to accumulated state corruption \(file clutter, environment drift\) over long episodes

Treat each high-level task as stateless. Use VM snapshots or container layers to reset the environment to a clean state between tasks, preserving only explicitly exported artifacts. Combine with 'computer use' tools that include bash commands for state inspection before acting.

Journey Context:
Long-running computer agents accumulate garbage \(downloaded files, modified configs, background processes\) causing 'works on my machine' drift and nondeterministic failures. The reliable pattern treats the computer environment as ephemeral: fork from a clean image \(Docker snapshot, VM checkpoint\), execute the task, export results to object storage, destroy the environment. For debugging, capture the full filesystem diff. This requires agents to be designed for statelessness \(idempotent tools\), but eliminates an entire class of Heisenbugs caused by previous task residue. Anthropic's computer use documentation emphasizes this for production reliability.
