## When to prefer this

Choose this endpoint when you need deterministic, reproducible length and structural metrics specifically for a project brief document. It is ideal when you want consistent, rule-based analysis without any AI-generated prose or fact-checking, and when you are working within a pipeline that processes project management documents at scale. Prefer it over general-purpose NLP APIs when cost predictability ($0.01 USDC per call) and bounded, template-driven output are priorities.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
