# NousResearch/hermes-agent · Agent loop-detector ignores volatile execution metadata

## Open now

- Nothing open on GitHub.

These items address a bug where volatile or per-call metadata (such as execution timestamps or transient fields) was included in the loop-detection hash, causing the agent to fail to recognize repeated tool results as loops. One report documents a severe real-world consequence: a wait loop for background subagents ran to the iteration ceiling, wasting 190 calls over 84 minutes before human intervention.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.

- **Recommended:** read PR #124724 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-124724`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #124072: \[Bug\]: Waiting on background subagents can deadlock a turn — execute_code-only wait loop ran to the iteration ceiling with zero guard activity (84 min, 190 wasted calls, human abort)
