# NousResearch/hermes-agent · OpenRouter output-cap error parsing and loop guard

## Open now

- Nothing open on GitHub.

Addresses a bug where parse_available_output_tokens_from_error() did not recognize the OpenRouter/Nous 'in the output' error format, causing agents to enter an infinite compression or auto-reset loop. Changes add detection of this format and a guard against the resulting infinite loop.

## TL;DR

- 8 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 6 PR(s) closed without merging.
- A fix was merged to main in PR #40589. Verify it addresses your case.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.25`: 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.
