Agent Factory is a paid reference library designed for individuals and teams building AI agents. It provides a curated collection of resources organized into three formats: long-form articles, copy-ready build prompts, and installable skills. The library contains 41 articles that offer field notes on the reasoning behind building, shipping, and selling AI agents. It also includes 39 prompts that serve as build specifications with predefined problems, stacks, and steps. Additionally, there are 19 installable skills for Claude, which can be copied as a SKILL.md file or downloaded as a zip folder and installed directly. The platform is structured as a one-time purchase for a single price of $49, with no subscription required. All content is searchable and kept current. Users can access the library through an account system, with a sign-in option for existing users. The site also features a separate publication called "The State of Production Agents," which provides real operating numbers from production agents and is delivered via email a few times a year after email confirmation. Typical use cases include researching best practices for agent development, obtaining ready-to-use build prompts for specific problems, and integrating prebuilt skills into Claude workflows. The content emphasizes practical metrics such as completion rates on real tasks rather than benchmark scores, and it covers topics like building evaluation sets that catch real failures, hiring priorities for agent products, and the importance of vertical brand as a moat. Technical requirements are minimal: users need access to Claude to install the skills, and the prompts are designed to be copy-ready for immediate use.
