📄 Description

Summary

  • Fixes incomplete token usage metadata in CoT agent strategy
  • Adds ExecutionMetadata class with comprehensive token tracking
  • Ensures proper billing and usage tracking for function calling agents

Changes Made

  1. Added ExecutionMetadata class: A Pydantic model that properly structures all token usage fields with default values
  2. Implemented from_llm_usage method: Safely converts LLMUsage to ExecutionMetadata, handling None cases
  3. Updated execution_metadata output: Now includes all token calculation fields:
    • prompt_tokens, prompt_unit_price, prompt_price_unit, prompt_price
    • completion_tokens, completion_unit_price, completion_price_unit, completion_price
    • latency
  4. Incremented version: Updated manifest.yaml from 0.0.23 to 0.0.24
