Write Once,
Reuse Endlessly
The open-source platform for modular, composable AI specs. Build a library of reusable spec modules, compose them into recipes, and share with the community.
Built for spec engineers
Everything you need to manage, compose, and share your specs.
Modular by Design
Like building blocks for your AI workflow.
Write small, focused specs and compose them into larger systems. Reuse the same module across multiple recipes without duplicating work.
Scoped to Your Stack
Specs that fit your stack.
Tag specs to specific scopes like languages, frameworks, or standards. Filter by scope to find exactly what works for your environment.
Compose Recipes
From specs to your repository.
Combine specs into full recipes and commit the composed result directly to your GitHub repository. Your spec library, version-controlled.
Share with the Community
Public or private, your choice.
Publish specs publicly for others to discover and learn from, or keep your collection private for your team.
Fork and Iterate
Build on community work.
Fork any public spec, refine it for your use case, and make it your own. Every fork links back to the original so credit is always preserved.
Multi-Format Editor
Text, YAML, or Markdown.
Write specs with a full-featured code editor. Syntax highlighting, auto-indent, and language switching built in.
Install the CLI
Manage specs from your terminal. One command to get started.
