}Validate Tool Call
Validate a tool call before execution.
This endpoint should be called before allowing an AI agent to execute any tool/function call. It validates:
- Tool is in allowed list
- Arguments are safe (no injection, no sensitive paths)
- Agent hasn’t exceeded rate limits
- Behavior is consistent with previous patterns
