Ready-to-use knowledge for your codebase.
Curated packages of memories, rules and skills, pre-scoped to the paths they belong to. Add one and your AI assistant applies it where it matters, then it evolves with your project.
Free, Apache-2.0Published byPathrule
A pattern is a small, opinionated bundle of memories, rules and skills for a single topic — server components scoped to your app folder, a migration convention at the database layer, a review checklist at the root. The mix is composed from the subject, so a security pattern leans on strict rules and an architecture pattern leans on conventions worth remembering.
Everything here is free and Apache-2.0. Import a pattern with its token and each piece lands at the path it belongs to; remove it the same way. It is a starting point that becomes your own context, not a dependency you are locked into.
