What problem does it solve? Teams often pick a validation method based on the tools they already have, then reverse-engineer a threshold the probe can pass, producing evidence that cannot change the roadmap. This Skill forces the kill criterion to be written before any probe is chosen, so the cheapest test that could actually stop the build gets selected. ## Core Features & Use Cases - Risk classification and probe matching: Classifies an assumption as value, usability, feasibility, or viability risk, then matches it against a matrix of nine probe types (fake door, painted door, concierge, Wizard of Oz, pre-sale, and more) with each probe's signature false positive. - Pre-registered kill criterion: Produces a four-part contract (signal, threshold, sample floor, alternative) agreed in writing before the probe runs, with the result record keeping the threshold beside the observed number. - Blast radius review: Checks who sees the probe, whether they are in a vulnerable moment, what is fabricated, and regulatory exposure before anything touches real customers. - Use Case: A team finishing a Lean UX Canvas takes its Box 7 riskiest assumption and receives three candidate probes with a comparison table, one disqualified with a reason, and a checkpoint where the humans pick the probe. ## Quick Start Ask the assistant to use the pol-probe-advisor skill to choose a Proof of Life probe for the riskiest assumption from your Lean UX Canvas Box 7.
