Report #41289

[frontier] How do I prevent Claude's Computer Use from getting stuck in infinite screenshot-action loops when the UI doesn't change?

Implement deterministic loop detection: maintain a ring buffer of the last N screenshot hashes \(e.g., 3\). If the current screenshot hash matches any in the buffer AND the predicted action is identical, break the loop and escalate to the user. Combine with max\_iterations \(e.g., 100\) and action diversity checks \(prevent same action >3 times\).

Journey Context:
Computer Use agents often oscillate \(click, same screenshot, click again\) when buttons are unresponsive or already selected. Anthropic's best practices \(late 2024/early 2025\) emphasize deterministic loop breaking \(hash comparison\) rather than hoping the LLM notices repetition, which it often doesn't. Tradeoff: may break legitimate repeated actions \(scrolling down a long page\), requires careful hash tolerance \(perceptual hashing\). Alternatives: No detection \(runaway costs\), LLM-based reflection \(expensive, unreliable\).
