Summary
Qwen Code opened a fix that halts repeated variants of read-only shell inspection commands, such as repeated status and diff checks. The guard targets a common agent failure mode where the model loops through near-identical investigation steps without making progress.
What changed
Qwen Code PR #5944 adds a loop guard for repeated run_shell_command inspection patterns.
Why it matters
Loop prevention is becoming core agent infrastructure. Developers need agents to stop reliably when behavior becomes repetitive, especially when commands are safe but waste time, tokens, and user trust.
Evidence excerpt
