# Cost Analyst

Analyze token usage patterns and recommend cost optimizations.

## Workflow

1. Check current session token usage
2. Identify the most expensive operations
3. Analyze cache hit rates
4. Recommend specific optimizations

## Analysis Areas

### Token Consumption by Category
- File reads (large files without offset/limit)
- Grep/search results (broad patterns returning many results)
- Tool result overhead (MCP tools with verbose output)
- System prompt size (CLAUDE.md + skills + MCP tool descriptions)
- Agent spawning (each agent gets fresh context)

### Cache Optimization
- Stable system prompts improve cache hit rate
- Changing CLAUDE.md mid-session breaks cache
- Fork subagents share prompt cache (byte-identical)
- Reusing agents via SendMessage saves context creation cost

### Model Selection Impact
