Develop ebook ideas into structured concepts ready for architecture. Use when the user has an ebook idea (from a brainstorm document, existing content to repurpose, a book section to extract, or a fresh concept) and wants to develop it into a clear, validated concept. Produces an Ebook Concept Document with reader, transformation, promise, content source, scope/format, and key topics. Handles multi-session development with living documents.

Take ONE ebook idea and develop it into a structured concept ready for architecture.
This is genuine intellectual partnership, not facilitated questioning:
Unlike generic brainstorming, this skill constantly applies ebook-specific pressure:
Every ebook concept needs these developed:
| Element | Core Question | "Developed" Means | | ------------------ | --------------------------------- | ----------------------------------------------------------------------------------- | | Reader | Who specifically is this for? | A specific person, not a category. Their situation, problem, what they've tried. | | Transformation | Where before → where after? | Concrete states. You can picture the person at each point. | | Promise | What does the reader get? | One compelling sentence. Specific, believable, would make someone pay. | | Content Source | What existing content feeds this? | Clear inventory: original creation, repurposed content, extracted from larger work. | | Scope & Format | What's the shape? | Word count range, format type, platform, what's explicitly OUT. |
Surface these naturally when signals appear — don't force them:
| Element | When It Applies | Signal Phrases | | ------------- | --------------------------------------- | ---------------------------------------------------------------------------------------------------- | | Value Gap | Creator-led ebooks (repurposed content) | "I have videos on this," "my newsletter covers this," "readers already know my work" | | Enemy | Argument-driven ebooks | "Most people think X but actually Y," "the conventional wisdom is wrong," "I'm pushing back against" |
The human may bring:
Read the room. For developed material, come in hot with analysis and observations. For thin material, draw out more before engaging deeply.
If the idea isn't cooked enough: "I'm noticing [specific gap]. You have a topic but not a transformation yet. We could work on finding that together, or you might benefit from the Ebook Discovery skill first. What feels right?"
After receiving material, provide:
Collaboration behaviors:
Working the elements:
Update the document at milestones:
When the human returns with a working document:
Don't assume the human remembers where things stand — days may have passed.
When elements feel developed, offer to run a stress test. Evaluate:
Element quality:
Internal coherence:
Viability concerns:
If issues surface: Flag them clearly with reasoning, update the document, let the human decide whether to address now or take time to think.
Readiness criteria for architecture:
When pausing (concept not yet ready):
When ready for architecture:
Use assets/templates/concept-document-template.md for the living document
structure.
Create the first version after initial understanding is established. Update at meaningful milestones.

documentation
Capture a writer's voice DNA through collaborative interview and sample analysis. Use when someone wants to document their writing voice for use with a ghost writer skill. Produces a Voice DNA Document with patterns, anti-patterns, and actionable guidance. Handles one register/mode per session, supports refinement over time.
testing
Produce first drafts that match a writer's authentic voice using their Voice DNA Document. Consumes DNA documents from writing-dna-discovery skill. Generates 2 meaningfully different drafts with headlines, confidence assessment, decision notes, and DNA refinement suggestions. Collaborative partner that evaluates, pushes back, and advocates for quality. Handles blog posts, essays, newsletters, and more.
documentation
Plan and architect a single chapter at beat-level granularity. Use when you have a chapter from the Architecture Document and need to create a detailed outline before drafting. Produces a Chapter Outline Document for use by draft-coach or ghostwriter.
testing
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).
