- ·Thin adapter files, real components in module
- ·Page shells with <x-extension> anchors
- ·Extension files mount components via <x-component>
- ·Alpine store composition
Use Cases
- →Building a new browser module in the Space Agent runtime
- →Deciding where to place code based on layer (L0 vs L1/L2)
- →Creating a frontend feature using extension and component patterns
Best for
- ✓Admin users building modules
- ✓Developers learning layered runtime

Build new browser modules in the layered Space Agent runtime and use the extension, component, and Alpine store patterns correctly.
metadata:{"when":{"tags":["admin"]}}
Use this skill when the user asks how to build a module, where code should live, how layers work, or how the extension/component/Alpine runtime composes the frontend.
Layer Model
L0is firmware. Repo-owned first-party code belongs here.L1is group customware. Use it for group-level overrides and additions.L2is user customware. Use it for per-user overrides and additions.- First-party source for this repository should normally live under
app/L0/_all/mod/_core/.... L1andL2are runtime state, not the home for durable repo-owned product code.
Module Layout
- Browser modules are namespaced as
mod/<author>/<repo>/.... - A first-party module usually lives at
app/L0/_all/mod/_core/<feature>/. - Keep real implementation files in the module folder.
- Keep
ext/html/adapter files andext/js/hook files thin. They should usually mount a real component or provide a focused hook, not hold the whole feature.
How The Frontend Composes
- Page shells in
server/pages/stay thin and expose<x-extension id="...">anchors. - Matching HTML extension files live under
mod/<author>/<repo>/ext/html/<anchor>/....
