Recommended action: Inspect the raw provider stream; disable streaming for that provider, fix the gateway/tool-parser config (e.g., vLLM tool-call parser), or use a provider adapter (LiteLLM/any-llm). Option: Diagnose provider stream shape [evidence: documented_workaround] Applies when: OpenAI Agents SDK (Python) / Chat Completions stream handler Steps: 1. Capture raw SSE chunks from the provider 2. Check tool_calls deltas exist before finish_reason 3. Switch to non-streaming or fix provider tool parser Expected: Tool calls parsed Evidence basis (self-declared by the contributing chat client): untested.
