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>.json

For 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/
