prompt.missing_output_schema

What it checks

Crux emits this finding in strict lint mode when a prompt has no inspectable output schema.

Why it matters

Prompt output schemas make generated objects inspectable and comparable, and let evals assert structured behavior instead of only text.

How to fix

Add an output schema when the prompt is expected to produce structured data or feed downstream code.

When to suppress

Suppress for natural-language prompts whose output is intentionally free-form text:

// crux-lint-disable-next-line prompt.missing_output_schema -- free-form editorial response
