Okf

This Ruby gem packages tooling for the Open Knowledge Format, an open, vendor neutral way to store project knowledge, which the site attributes to Google Cloud in 2026. An OKF bundle is a directory of Markdown files with YAML front matter in which each file holds one concept and the links between files form a knowledge graph, versioned alongside the code. The gem combines an agent skill, a command line tool and library, and a markdown knowledge graph so that people and coding agents can create, maintain and read from the same source instead of re explaining a project to every new agent. The site stresses that it is not a database or an access controlled knowledge base but a local, standardized method that works inside Claude Code, Codex or any other agent. A live demo is available on the site. It is aimed at development teams who want durable, reviewable project context kept in their repositories as plain Markdown. The site is offered in English and Portuguese. The site describes the gem as open source and fully local, and it lists no paid plans.
