## Title

    Proposed fix: [Azure OpenAI GPT-4.1] Large tool/function definitions >300K tokens fail with context_length_exceeded / string_above_max_length / generic 500 despite 1M context

## Body

    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
