- Added textVerbosity configuration schema to allow user control over model response length.
- Integrated textVerbosity into settings-aware stream processing for "openai-responses" and "openai-codex-responses" APIs.
- Updated settings stream tests to verify that verbosity settings correctly apply while respecting caller overrides.
AgentSession.#buildAdvisorRuntime constructed the advisor Agent without the provider-shaping options the SDK installs on the main agent: the streamFn wrapper that applies providers.openrouterVariant / providers.antigravityEndpoint / providers.maxInFlightRequests / model.loopGuard.*, the onPayload/onResponse/onSseEvent hooks, the shared providerSessionState map, transformProviderContext (snapcompact, secret obfuscation, image clamping), and a stable promptCacheKey. Advisor turns therefore dropped the OpenRouter sticky-routing variant suffix, used a different prompt_cache_key than the main turn, and skipped the per-session provider hooks — producing intermittent OpenRouter response-cache misses across consecutive advisor calls.
Extract the inline streamFn wrapper in sdk.ts into a shared createSettingsAwareStreamFn helper (packages/coding-agent/src/session/settings-stream-fn.ts) and pass it (plus transformProviderContext) through AgentSessionConfig as advisorStreamFn / transformProviderContext. #buildAdvisorRuntime now hands the advisor Agent the same streamFn, hooks, providerSessionState, promptCacheKey (= advisor session id), and transformProviderContext as the main turn. Adds getAdvisorAgent() accessor on AgentSession for diagnostics and parity tests.
