Highlights
- Applies hard-constraint Noul gates before ranking, which résumé-style matchers do not.
- Returns a fit band plus a per-feature score so an agent can see what drove the order.
- Restricts preferences to property and location features and rejects protected fields in code.
- Treats listing remarks as untrusted input and ships injection fixtures with the evaluator.
Watch out
It is an agent's decision aid, not an automated offer or a fair-housing determination; the fair-housing guarantee is a schema limit that must be kept as the input shape evolves.
Questions about this entry
Short answers drawn from the linked project or page.
A buyer's stated preferences against a listing's structured features and free-text remarks, returning a Choice for the best-fit band and a per-feature Score so the agent sees which preference drove the match.
Real-estate matching weighs hard constraints a résumé does not have, such as school district and commute, and the tool treats those as gating Nouls before any ranking happens.
Preferences are restricted to property features and location, never protected characteristics, and the README documents that the input schema rejects those fields before a request is built.
A ranked shortlist with the reason per listing, plus the raw probabilities, so an agent can override the order and still see the model's reasoning rather than a black-box rank.
Free-text remarks are treated as untrusted input and passed in structured instructions, and the evaluator ships a set of remarks with embedded instructions to test for injection.
TypeScript and a Typesafe key, with an adapter for a common MLS JSON shape. A fixture of 200 anonymized listings is included for tuning the fit bands.
