Summary
A high-attention Qwen Code issue reports an unattended agent session consuming large amounts of DeepSeek credits while leaving no usage records. The issue turns session timeout, auditing, and runaway-agent controls into a trust problem rather than a simple bug report.
What changed
A Qwen Code issue surfaced a zombie-session failure mode where an unattended agent reportedly ran for hours, consumed credits, and did not log usage in usage_record.jsonl.
Why it matters
Unlogged token consumption is one of the sharpest adoption risks for long-running coding agents. Teams need reliable cutoffs, audit trails, and cost visibility before they can trust autonomous sessions in production workflows.
Evidence excerpt
Agents Radar highlights Qwen Code issue #5964 as a zombie-agent report involving unattended runtime, DeepSeek credit burn, and missing usage logs.
