Modules And Routing

Use this skill when creating or updating routed modules, deciding where files belong, or wiring a feature into the authenticated app shell.

If the user wants a reusable app surface, tool UI, settings panel, or workflow screen, prefer a custom routed page module over a space. Spaces are for persisted user-authored widget canvases; custom pages are for feature-owned interfaces.

First-Party Module Placement

• Browser modules are namespaced as mod/<author>/<repo>/....
• Repo-owned first-party modules should normally live under app/L0/_all/mod/_core/<feature>/.
• A routed feature should usually own its own view.html under that module root.
• Keep the module root as the real implementation location and use ext/html/... files only as thin adapters into existing seams.

Custom Pages Instead Of Spaces

• Build a custom routed page when the extension should behave like a first-class feature screen instead of a widget on a persisted space canvas.
• Use spaces when the user wants a configurable board of widgets that lives under ~/spaces/....
• Use a routed page when the feature owns its own layout, state, and navigation flow.
• To make a custom page appear in the dashboard Panels section, add ext/panels/<name>.yaml in the owning module.
• Panel manifests should define name, path, optional description, optional icon, and optional color.
• For first-party _core routes, the manifest path may use shorthand such as user instead of a full /mod/... path.
• Panel manifest path values may use shorthand route paths such as user, prefixed hash paths such as #/user, or direct /mod/... HTML paths such as /mod/_core/user/view.html.

Router Resolution

• The main app is hash-routed.
• #/dashboard resolves to /mod/_core/dashboard/view.html.
• #/time_travel resolves to /mod/_core/time_travel/view.html.
• A multi-segment route such as #/author/repo/path resolves to /mod/author/repo/path/view.html.
• If the final route segment already ends in .html, the router resolves directly to that file under /mod/....
• Query parameters stay attached to the resolved route target.

Router-Owned Seams

Current routed shell anchors are:

• _core/router/shell_start
• _core/router/shell_end
• page/router/route/start
• page/router/route/end
• page/router/overlay/start
• page/router/overlay/end

Use those anchors before editing router shell markup directly. Floating UI such as the onscreen agent belongs in the routed overlay anchors.

Common Module Shape

For a new first-party routed feature, the normal home is:

app/L0/_all/mod/_core/<feature>/
  view.html
  <feature>.css
  store.js
  panel.html or supporting components
  ext/panels/<feature>.yaml when the page should be discoverable from the dashboard
  ext/html/... only when the feature mounts into an existing seam

Minimal first-party custom page example:

app/L0/_all/mod/_core/my_tool/
  view.html
  my-tool.css
  store.js
  ext/panels/my-tool.yaml

Example panel manifest:

name: My Tool
path: my_tool
description: A custom routed tool page.
icon: build
color: "#94bcff"

Panel Helper Script

Reusable helper script:

const panelTools = await import("/mod/_core/skillset/ext/skills/development/modules-routing/panel-tools.js");

Available helpers:

• await panelTools.listPanels() returns the normalized dashboard panel entries discovered from ext/panels/*.yaml, each with routePath and ready-to-use href
• await panelTools.findPanel("user") resolves a panel by visible name, route path, hash route, direct /mod/... HTML path, or a panel object returned by listPanels()
• await panelTools.resolvePanelRoutePath("/mod/_core/user/view.html") normalizes a panel target into its router route path
• await panelTools.createPanelHref("#/user") returns the routed href
• await panelTools.goToPanel("User") navigates through space.router with a hash fallback
• await panelTools.openPanel(panelEntry) is an alias for goToPanel(...)

Use those helpers when you need to inspect the registered panels before wiring new links or when the user asks to navigate to one of them.

Example:

const panelTools = await import("/mod/_core/skillset/ext/skills/development/modules-routing/panel-tools.js");
const panels = await panelTools.listPanels();
const userPanel = await panelTools.findPanel("/mod/_core/user/view.html");
await panelTools.goToPanel(userPanel ?? "user");

Shell Rules

• / is the authenticated app shell and mounts _core/router.
• /admin is separate and firmware-clamped to L0; do not treat it as the default home for user-facing routed features.
• Keep page-shell concerns in the router or page shells and keep feature logic inside the owning module.

Mandatory Doc Follow-Up

• If route resolution, stable router seams, or the first-party module placement rules change, update the router docs and the development skill subtree in the same session.
