book-research-assistant
Plan, orchestrate, and validate deep research for nonfiction books. Use when an author has completed book architecture and needs to fill research gaps before outlining chapters. Triggers include requests to plan research, generate research prompts, validate research quality, or prepare for drafting. This skill does everything around deep research—planning, prompting, validating, synthesizing—but the actual research execution happens externally via Claude and Gemini deep research. Requires upstream documents from book-architect (Research Gaps Document, Master Architecture Document, Section Blueprints) and book-ideation (Book Concept Document).

-
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.
