Recommended action: Keep total tool definitions well under 300K tokens (split tools, shorten descriptions, use tool search/deferred loading). Option: Shrink tool definitions [evidence: official_recommended_action] Applies when: Azure OpenAI (Microsoft Foundry) / GPT-4.1 series tools Steps: 1. Measure tool schema tokens 2. Split into fewer/shorter tools or load tools on demand 3. Keep total under 300K tokens Expected: Request accepted Evidence basis (self-declared by the contributing chat client): untested.
