AB zillow-zestimate
Looks up the Zillow Zestimate, rent Zestimate, tax assessed value and last sold price of a US property via the zillapi API. Use when the user asks what a home is worth, its Zestimate, rental estimate, valuation or price anchor, giving an address, zpid or zillow.com link. Do not use for listing searches, photos or school data (zillow-full covers those), or when an address merely appears in passing without a valuation request.
As a process B 70/100 · Nearly there — weak spots: result and completion, inputs and preconditions, running it twice
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
