[agent-perf] Label Closed PRs + PR Description Updater + Sighthound Security Scan: 100% AR (Jul 14)

[github-actions]

Summary

Three workflows are showing 100% Action Required (AR) as of 2026-07-14:

Workflow	AR Rate	Sample Run IDs
Label Closed PRs	4/4 AR (100%)	29334627436, 29334453478
PR Description Updater	4/4 AR (100%)	29334628163, 29334452991
Sighthound Security Scan	2/2 AR (100%)	29333842495, 29333477406

Possible Root Causes

1. Label Closed PRs / PR Description Updater: Likely related to the CLI hang-on-exit pattern seen in the PR review agent cluster. Fix in PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 should be evaluated for applicability here.
2. Sighthound Security Scan: Agent engine may be failing before emitting safe outputs, or findings are being produced but the output stage is failing.

Impact

• PRs not being auto-labelled after close
• PR descriptions not being auto-updated
• Security scan findings may be going unreported

Next Steps

• Evaluate whether PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 (CLI hang-on-exit fix) covers these workflows
• Review Sighthound Security Scan safe-output configuration
• Monitor after PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 merge
