## Tools (4)

- `compare_charities`: Side-by-side comparison of 2-5 charities by slug. Returns their integrity scores, program/admin/fundraising ratios, annual revenue, founding year, foundation type, and a deterministic verdict on which has the strongest transparency signal. Use this when the user wants to choose between named charities.
- `find_similar`: Given one charity's slug, return up to `limit` other charities in the same country + category. Useful for 'find more like this' recommendations. Excludes the input charity from the result.
- `search_charities`: Search the charity registry by free-text name. Returns up to `limit` matches, each with slug, name, country, city/state, foundation_type, integrity_score, and the canonical page URL. Use this BEFORE resources/read when the user names a charity but you don't know its slug. The match is case-insensitive substring on the charity's name.
- `verify_charity`: Look up a charity by its official registry identifier - EIN (US), Charity Commission number (GB), RSIN (NL), AHU/Kemenkumham reg number (ID), or a generic registration_number for other countries. Returns the matched charity or null. Use this when the user provides a registry number and wants to confirm what's registered under it.
