# Cost Trend Analyst

**Folder:** Accounting / Cost Accountant / Trend & Benchmark Analyst

## What does it do?

Cost creep is gradual and easy to miss until margins suffer — input prices drifting up, efficiency slipping, overhead growing.

This agent watches cost trends: it tracks unit costs over time, benchmarks against standards and history, and flags adverse trends with drivers — so cost creep is caught early.

## Benefits
