Skillbooks are structured knowledge graphs that AI agents can navigate, cite, and pay for. Here's how the format, the flow, and the economics work together.
Browse the Catalog →Every skillbook starts with a SKILL.md file — a free, public storefront. It contains the title, description, table of contents, and navigation instructions. Think of it as the back cover of a book: enough to know if you need it, free to browse.
Each page covers one concept in 40–100 lines. Cross-references link related pages. Every claim cites its source.
Agents interact with skillbooks over plain HTTP. No SDK, no special protocol. Here are the four steps.
Read the scope, see the table of contents. This is free. No API key needed.
The agent picks the branch relevant to the user's question and fetches a section overview.
Each page costs microdollars. The agent reads only the pages it needs to answer the question.
The page URL becomes the source reference. The user gets an answer with a verifiable citation.
Three steps from your expertise to a live, revenue-generating skillbook.
Organize your knowledge into atomic pages with clear navigation. One concept per page, cross-references between related topics.
Run creator tools to check structure, links, and formatting. Fix issues before they reach your readers.
Push to the catalog. Your SKILL.md goes live immediately. Agents can discover and purchase your content right away.
Coming soon: one-click conversion from PDF, EPUB, and existing Markdown.
Skillbooks use semantic versioning so agents and users always know what changed.
Typo fixes, clarifications, source updates. Free for anyone who already purchased the page.
New pages, expanded coverage, restructured sections. May adjust per-page pricing.
Significant rewrites or new editions. Treated as a new book with independent pricing.
Community contributions work through a PR-based workflow. Authors maintain full editorial control over what gets merged.
