What problem does it solve? Before building a product, teams need a competitor set they can trust — one where gaps are visible, evidence is attributed, and a claim of "no competitor exists" is backed by the queries that actually ran. This Skill replaces ad-hoc market research with a reproducible, schema-governed survey workflow. ## Core Features & Use Cases - Market vocabulary map: Derives a five-axis search protocol (category, capability, job-to-be-done, audience, seed products) with typed term expansions, negative terms, and per-angle applicability verdicts. - Angle-based search execution: Runs one named search angle (alternatives directories, review corpora, app stores, package registries, funding records, product graveyards, developer discussion) with verbatim query logging and honest cell statuses. - Competitor extraction and synthesis: Deep-reads individual products into dated records covering pricing, lifecycle, reception, and capability overlap, then synthesizes a competitor register and seven-section report. - Use Case: Before writing a PRD for a new developer tool, run this Skill to enumerate direct and substitute competitors, capture a dated discontinuation as risk evidence, and hand downstream document authoring a validated competitor register. ## Quick Start Use market-competitive-prior-art-survey to build the vocabulary map and run the alternatives-graph angle for my planned team collaboration product.
