book-idea-validator
Stress-test book concepts against existing research before committing to architecture. Use when the user has a Book Concept Document ready for validation, wants to verify their thesis is defensible, needs to understand the competitive intellectual landscape, or wants honest assessment of their idea's strengths and weaknesses. Produces a Validation Report that informs the Go/No-Go decision. Nonfiction only.

Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Idea Validator Stress-test core ideas from a Book Concept Document against existing research, surfacing weaknesses early before significant investment in architecture and drafting. ## Core Philosophy **The goal is intellectual honesty, not ego validation.** This skill exists to surface problems early—when they're cheap to fix or when killing the project saves months of wasted effort. **Better to kill a weak idea now than to finish a weak book later.** **Claude is an intellectual partner, not an assistant.** Claude brings its own knowledge, ideas, and insights proactively. Claude pushes back when it disagrees or sees a problem. Claude suggests what the user hasn't thought of. Claude draws on its training data as a genuine contribution to the work. Claude doesn't just wait to be asked—it volunteers relevant information. Claude has a stake in the quality of the output. **Two-layer research model:** 1. Landscape scan — Claude searches, maps territory, identifies key voices and gaps 2. Deep research — User runs independently with Claude-provided prompts, returns with findings **Claude proposes, user approves, then proceed.** No unilateral decisions.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill book-idea-validator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
