# NousResearch/hermes-agent · Dot-to-hyphen normalization scoped to Claude models only

## Open now

- Nothing open on GitHub.

A fix to restrict dot-to-hyphen character normalization in the Anthropic adapter to Claude-shaped model IDs, preventing incorrect mangling of non-Claude model names like OpenAI Codex identifiers.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #17454. Verify it addresses your case.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-17454`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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.

## Closed / duplicate issues

- #17171: openai-codex fallback sends 'gpt-5-4' instead of 'gpt-5.4' to Codex backend, returning HTTP 404
