COSS UI Particles Index
Particles are copy-paste-ready UI patterns built on coss primitives. Browse them visually at https://coss.com/ui/particles.
How to use this skill
- Describe the UI you need (e.g. "a form with validation", "a dialog with a form inside", "tabs with icons").
- Search this index for matching particles by component type and description.
- Fetch the JSON URL to get the full source code of the particle.
- Adapt the particle code to your needs.
JSON URL pattern
Each particle has a JSON manifest at:
https://coss.com/ui/r/<particle-name>.jsonFor example: https://coss.com/ui/r/p-accordion-1.json
Source code
Particle source files live in this repo at apps/ui/registry/default/particles/.
