…1 auth When using Alibaba (DashScope) with an anthropic-compatible endpoint, model names like qwen3.5-plus were being normalized to qwen3-5-plus. Alibaba's API expects the dot. Added preserve_dots parameter to normalize_model_name() and build_anthropic_kwargs(). Also fixed 401 auth: when provider is alibaba or base_url contains dashscope/aliyuncs, use only the resolved API key (DASHSCOPE_API_KEY). Never fall back to resolve_anthropic_token(), and skip Anthropic credential refresh for DashScope endpoints. Cherry-picked from PR #1748 by crazywriter1. Fixes #1739.

Merged via PR #2332. Your substantive commits were cherry-picked onto current main with authorship preserved. Thanks for the fix @crazywriter1! Both the dot-preservation and the 401 auth issues are now resolved. Also fixed a related dead-code issue in #2314 (model identity injection was checking for nonexistent provider names). |

Fixes #1739
1. Model name (dots)
When using Alibaba (DashScope) with an anthropic-compatible endpoint (e.g. coding plan), model names like
qwen3.5-pluswere being normalized toqwen3-5-plus. Alibaba's API expects the dot. As the issue author noted: "hermes replaces dots in the modelname with dashes. qwen3.5-plus -> qwen3-5-plus" we fix that.2. 401 auth (wrong credential)
When
provideris alibaba orbase_urlcontains dashscope/aliyuncs, the agent must use only the resolved API key (DASHSCOPE_API_KEY). If that key was missing/empty, the code fell back toresolve_anthropic_token()(ANTHROPIC_TOKEN), so an Anthropic token was sent to Alibaba's endpoint → 401. We now never fall back to Anthropic token for Alibaba/DashScope; credential refresh also skips for that case.Changes:
normalize_model_name(model, preserve_dots=False)andbuild_anthropic_kwargs(..., preserve_dots=False)so model names keep dots whenpreserve_dots=True.providerisalibabaor base_url containsdashscope/aliyuncs: passpreserve_dots=Trueinto anthropic kwargs; for auth, use only the passedapi_key(noresolve_anthropic_token()fallback); skip Anthropic credential refresh.test_preserve_dots_for_alibaba_dashscopein test_anthropic_adapter.py.Testing:
pytest tests/test_anthropic_adapter.py tests/test_run_agent.pyall passed. Native Anthropic and other providers unchanged (only alibaba/dashscope path is special-cased).
