Overview
Content to Skill is a Claude Code marketplace plugin that transforms PDFs and EPUBs into structured, layered AI agent skills. Rather than producing flat summaries that lose nuance, it distills book knowledge into progressive-disclosure reference files that agents can load on demand - from 30-second overviews to deep conceptual dives.
The Challenge
Technical books contain dense, interconnected knowledge that's easy to forget when you need it most. Traditional summaries flatten the depth. AI agents need structured knowledge access where they can start with the big picture and drill into specifics as needed - but no tool existed to create that kind of layered knowledge architecture from source material.
Approach
The system uses a four-stage pipeline: chunk the document into sections, extract knowledge in parallel using subagents, synthesize findings into a cross-referenced knowledge map, and convert the result into 8-15 structured reference files with progressive disclosure. A companion Library View web app provides visual browsing with cover art and search. The tool is distributed through the Claude Code marketplace for easy installation.
Outcome
Published as an open-source tool on the Claude Code marketplace. Processes a 400-page book in roughly 42 minutes, producing reusable skill packages that any Claude Code user can install. The companion web app gives users a visual library grid for browsing and managing their converted books.
