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.
