# Session Cost Analysis
**Session**: Agent Ecosystem Consolidation and Optimization
**Date**: 2025-10-05
**Claude Model**: claude-sonnet-4

## Cost Summary
- **Total Cost**: €0.2760 ($0.3000 USD)
- **Token Usage**: 40,000 tokens
  - Input: 25,000 tokens × $3.00/M = $0.0750
  - Output: 15,000 tokens × $15.00/M = $0.2250

## Session Details
- **Session Type**: agent_development
- **Work Summary**: Comprehensive Claude Code agent ecosystem consolidation and optimization. Created datamodel optimization specialist agent with 4-week implementation gameplan targeting 60-80% label processing performance improvements. Migrated and enhanced 3 agents (testing-efficiency, requirements-engineering, agent-optimizer) from duplicate documentation to single source .claude/agents configuration. Integrated Issue #59 lessons learned into requirements engineering agent with practical toolkit commands and enhanced TDD8 workflow. Established DRY principle compliance by removing duplicate docs and creating symlink for agent visibility. Deliverables: 4 optimized agents, comprehensive datamodel optimization strategy, clean documentation architecture.

## Cost Allocation
This cost represents general development work and should be allocated to the appropriate cost category based on the nature of the session.

**Note**: This is a standalone cost note for work that is not tied to a specific tracked issue. For issue-specific work, use `markitect cost session track` instead.
