Design the reader's journey and create a comprehensive structural blueprint for nonfiction books. Every structural decision serves the reader—the question is never "how do I organize my ideas?" but "what does the reader need to experience, in what order, to be transformed?"

Stress-test core ideas from a Book Concept Document against existing research, surfacing weaknesses early before significant investment in architecture and drafting.

Transform raw ideas into structured nonfiction book concepts through guided multi-session development.

Determine if a book is worth writing from a business perspective, specifically for Amazon KDP self-publishing.

Plan, orchestrate, and validate deep research for nonfiction books. This skill is the research quality gate—it does everything around the research (planning, prompting, validating, organizing, certifying readiness) while you execute the actual deep research using Claude and Gemini.

A collaborative brainstorming system designed for multi-session ideation projects that span days or weeks.

Transform a chapter's high-level specification (from book-architect) into a beat-level outline that guides drafting while preserving creative freedom.

An intelligent documentation system that analyzes codebases and generates thorough, comprehensive documentation tailored to your project type and audience needs.

Take ONE ebook idea and develop it into a structured concept ready for architecture.

Surface ebook ideas you didn't know you had. This is divergent/generative discovery ("what's here?") that feeds into Ebook Concept Development.

Produce first drafts at ~80% voice accuracy using a writer's Voice DNA Document.

Create structured documents that enable seamless continuity across Claude sessions.

Generate a structured, actionable launch checklist tailored to the user's app, target platform(s), and timeline. Walk through each phase sequentially, confirm completion of critical items, and flag blockers.

- A defined app concept (what it does, who it serves) - Target platform (iOS, Android, or both) - Revenue goal (hobby $1K/mo vs business $10K/mo) - No tools required — this skill produces strategy and implementation guidance

Install a fast local task workflow for single-project planning with `scripts/task.sh` (claim, done, status, reporting) backed by `tasks/TASKS.md` and optional `tasks/details/` notes. Use for lightweight in-progress task coordination, not full team issue tracking.

This skill provides guidance for creating effective skills.

Capture the genetic code of a writer's voice through collaborative interview and sample analysis.

Install strict Xcode Makefile tooling for iOS/macOS projects, including build/run/test scripts with AGENT_NAME-based per-agent isolation under build/. Use when a project needs reproducible local CLI builds without full app scaffolding.

Audit websites for accessibility issues and WCAG compliance. Use when checking accessibility, fixing a11y issues, or ensuring WCAG compliance.

Deploy a 2-layer parallel agent hierarchy for large, parallelizable work — big refactors, multi-file migrations, codebase-wide audits, bulk generation. A top-tier commander (Fable or Opus) orchestrates the swarms; the user picks a power level (Max Power / Heavy / Balanced / Economy) that sets the Opus/Sonnet/Haiku model mix per layer. Layer 1 is 3-50+ specialist agents, each with its own full context window; Layer 2 is 2+ sub-agents per member. Includes git safety, tiered sizing, a pre-deploy...

Deploys swarms of sub-agents for massive parallel data processing tasks. Unlike agent-army (which is for code changes), this is for DATA tasks -- processing 1000 documents, analyzing datasets, bulk content generation. Configurable swarm size, task distribution, result aggregation, progress tracking, and error recovery.

Designs and deploys custom agent teams for specific business workflows. Interactive discovery of business processes, then generates complete team configurations with specialized agent roles, tool access, communication protocols, and handoff rules.
