A Claude Code skill that validates a product idea against what people already say about the problem, in their own words, before anything gets built.

It harvests four open sources with no API keys or logins:

Source	How
Reddit posts and comments	Arctic Shift, the public Reddit research dataset
App Store reviews	Apple's customer-review RSS feed
Hacker News	Algolia search API
Stack Exchange	public API

Every item is tagged by the signal it carries: **problem**, **workaround** (DIY hacks), **tools** tried and abandoned, **money** (prices, willingness to pay), and a fifth idea-specific family (default: **external**, who holds the load for them today). The agent then reads the corpus, extracts a sourced evidence table with verbatim quotes, maps the competitor landscape, and writes a report: verdict, ranked problems, a language glossary, workarounds, what people pay, the gap, and a one-week V1 blueprint.

Extraction and synthesis run inside the agent; nothing calls a paid LLM API.
