Document the new streaming request behavior.
Streaming requests now add stream_options.include_usage by default. Document the compatible-provider behavior and the removeBodyFields opt-out so users can diagnose providers that reject this field.
As per coding guidelines, “Update docs when setup, commands, provider behavior, or user-facing behavior changes.”

Update
Documented the compatibility policy for streaming usage requests.
Addressed
- Streaming usage compatibility at
docs/integrations/overview.md:121— The integration guide now states that OpenAI-compatible streaming chat-completions routes request terminal usage by default, URL locality does not change that contract, incompatible routes can remove stream_options explicitly, and direct Ollama serialization is unaffected. — 9c3feca

Update
Updated the streaming compatibility guidance to cover the custom-provider fallback.
Addressed
- Streaming usage compatibility at
docs/integrations/overview.md:121— The guide now documents the one-time retry without stream_options when a server explicitly rejects the top-level field. It also keeps descriptor opt-outs authoritative and states that cancellations and unrelated client errors are not retried.
UpdateAddressed both requested follow-ups with cached-token accounting proof and compatibility documentation. Addressed

Findings

[P1] Retain a fallback for custom local servers that reject
stream_options
src/services/api/openaiShim/requestPreparation.ts:253
The removed!isLocalProviderUrl(request.baseUrl)guard was the only protection for generic local endpoints. After this change, a user who configures an arbitraryOPENAI_BASE_URLsendsstream_options: { include_usage: true }on every streaming chat-completions request, even though this is an optional extension rather than part of the minimum streaming contract. Known built-in routes can remove the field through descriptor metadata, but the normal custom-provider flow persists only an API key, base URL, and model; it cannot setremoveBodyFields.executeOpenAIRequestalso sends the serialized request as-is and has no one-time compatibility retry for an unsupported-field 4xx. A previously working strict local/OpenAI-compatible server therefore fails before it can stream any response, leaving the user unable to use streaming at all.Please address the root cause—capability is being inferred from network locality rather than represented as route capability—rather than merely adding more hostname exceptions. Preserve the compatibility default for unclassified custom/local routes and enable usage chunks only for routes known to support them, or add a user-configurable capability/opt-out that reaches request preparation. A narrowly classified, single retry without
stream_optionsis also a reasonable resilience layer, provided it cannot retry user cancellations or unrelated 4xx errors. Add an integration regression test that simulates a custom local server rejecting only this field and proves that streaming still completes without usage data.
UpdateAdded a bounded compatibility fallback for strict OpenAI-compatible streaming servers. Addressed

I found no merge-blocking issues. One low-risk follow-up is noted below.
Merge readiness
- Mergeable against current
main; all required checks are passing. - The P3 below is a non-blocking follow-up and should not delay merge.
Follow-up
-
[P3] Do not replay a tool-name validation error as a stream-options failure
src/services/api/openaiErrorClassification.ts:334
The free-text matcher treats any occurrence shaped likestream_options is unsupportedas a rejection of the top-level request field. Tool names are passed through from callers, so a provider that rejects a user-defined tool namedstream_optionscan returnTool "stream_options" is unsupportedorFunction: stream_options is unsupported. Both messages currently enter the new compatibility branch:executeOpenAIRequestdeletes the genuine top-levelstream_optionspayload and makes a second POST, only to surface the original tool-definition error again. This is low-risk because the first request already failed validation, but it unnecessarily consumes a request/rate-limit slot and violates the intended exact-field-only retry rule.Address the root cause by making the recovery decision depend on evidence that the request field was rejected, rather than the bare identifier appearing anywhere in provider prose. Prefer structured
param/validation-location evidence where it exists; for free-text fallback, require parameter/field wording and explicitly reject tool/function/schema contexts. Mirror the negative-context handling already present fortool_stream, and add regression cases for tool and function names ofstream_optionsthat assert no replay occurs.
