# 0.3.1 — 2026-04-04

## Added

- Search criteria echo on empty results — all 9 tools now return the filters that produced zero matches, helping diagnose why a query returned nothing.
- `buildSearchCriteria()`, `formatEmptyResult()`, and `SearchCriteriaSchema` in `format-helpers.ts` for consistent empty-result rendering across tools.

## Changed

- Empty-result format messages unified to "No results found" with echoed criteria and domain-specific suggestions (previously each tool had a bespoke message).
