- Bring your own agent. We don't ship a model. The strongest agents already live on your laptop.
- Open by default. Apache-2.0 / MIT across the stack. No locked surface, no telemetry.
- Local-first. Your projects, conversations, and IM bridges run on your machine first, cloud second.
- Skills are files, not plugins. Drop a folder, restart, it works. The
SKILL.mdconvention, end of story. - Design Systems are portable Markdown, not theme JSON. The 9-section
DESIGN.mdschema.
- Star the projects that resonate — cheapest, loudest signal.
- Add a skill — drop a
SKILL.mdfolder and open a PR on open-design or html-anything. - Add a design system — drop a
DESIGN.mdfolder and open a PR. - Write up your harness — contribute to harness-engineering-guide.
