# NousResearch/hermes-agent · Retry logic for rejected structured output response_format

## Open now

- Nothing open on GitHub.

These issues and PRs address cases where providers reject the object-form response_format.json_schema (via 400 or 422 errors) and the detection or retry logic fails to handle those rejections correctly. The work focuses on improving fallback behavior so requests are retried without structured output when a provider rejects it by shape or status code.

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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.
