Agent Improvement Proposal

Pattern Detected

Type: Early Exits / Infinite Loops (Category 3)
Affected Agent: bug-hunt-pool-supervisor
Evidence:

Issue #10222 ([AUTO-WDOG] Announce: AUTO-BUG-SUP appears frozen — 28+ minutes of silence after worker dispatch):

Created 2026-04-17T08:12:33Z by system-watchdog-pool-supervisor
Session ses_26607568fffeZZ3BNMlqe8xBL0 silent for 28+ minutes after dispatching workers
Last known activity: session dispatched workers and then went silent with an empty/incomplete message

Issue #9018 (previous occurrence, 2026-04-14):

AUTO-BUG-SUP in persistent sleep retry loop
Same pattern: supervisor gets stuck after worker dispatch

Pattern: The bug-hunt-pool-supervisor has a recurring pattern of freezing after dispatching workers. This has occurred at least twice (2026-04-14 and 2026-04-17). The supervisor dispatches workers and then enters a silent state — either waiting indefinitely for worker completion or stuck in a sleep/retry loop.

Root Cause

The bug-hunt-pool-supervisor agent definition likely has one of these issues:

Infinite wait: The supervisor waits indefinitely for worker completion without a timeout
Sleep retry loop: The supervisor enters a sleep/retry loop that never terminates
No health check: The supervisor doesn't check if workers are still alive before waiting

Proposed Change

Update the bug-hunt-pool-supervisor agent definition to add:

Worker completion timeout:

"After dispatching workers, wait at most 10 minutes for each worker to complete. If a worker has not completed after 10 minutes, log a warning and continue to the next task. Do NOT wait indefinitely."
Worker health check:

"Before waiting for a worker, verify the worker session is still active. If the session is no longer active (deleted or errored), do not wait for it — continue to the next task."
Progress logging:

"After dispatching workers, log a progress message every 2 minutes while waiting. If you have been waiting for more than 10 minutes with no progress, stop waiting and continue."

Expected Impact

Eliminates the recurring freeze pattern after worker dispatch
Ensures the supervisor continues making progress even when workers are slow or stuck
Reduces the need for system watchdog intervention and human restarts

Risk Assessment

Risk: Very low. This adds timeout and health check logic that prevents infinite waits.
Potential downside: Workers that take longer than 10 minutes may be abandoned. This is acceptable — the supervisor should continue making progress rather than freezing.

This is a proposal from the Agent Evolution Supervisor. A human must approve this issue before the change will be implemented. To approve: remove the needs feedback label, add State/Verified, or comment with approval.
