Mobile app structure

The source of truth for how code is organized in web/mobile. Load it before creating any file there.

Layout

web/mobile/
  src/
    pages/                    # Pages Router route shells ONLY — no logic, no layout JSX
    features/
      <feature>/              # e.g. sessions/, chat/, auth/, project-drawer/
        <Component>.tsx       # one component per file, named export = file name
        states/               # designed states for this feature
          <X>Skeleton.tsx     # mirrors the final layout geometry (no shift on swap)
          <X>Empty.tsx        # designed empty state with a call to action
          <X>Error.tsx        # error + retry affordance; preserves user input
    components/ui/            # shadcn registry components (see mobile-shadcn-conventions)
    lib/                      # cn util, motion presets, api glue, context resolution
    styles/                   # globals.css, theme.generated.css (generated)
  scripts/                    # generate-shadcn-tokens.ts (token bridge)

Rules

• Pages are thin shells. A page file resolves route params and renders one feature screen component. Anything else belongs in features/.
• One component per file. No secondary exported components; small private helpers inside a file are fine if they never leave it.
• Every data-bearing component has designed states. Before writing the happy path, create the states/ siblings (skeleton, empty, error). A screen is not done if any of its states is a browser default or an unstyled string.
• Data flow: components get data via hooks from @agenta/* packages (@agenta/entities, @agenta/shared, later @agenta/chat) or thin fetchers in lib/. NEVER import @/oss/*, @agenta/oss, @agenta/ee — the mobile app has zero app-layer imports (lint enforces this).
• No provider fleet. _app.tsx stays minimal; add a provider only when a concrete feature needs it, scoped as narrowly as possible.

Adding a new feature (checklist)

1. Create src/features/<feature>/ with the screen component.
2. Create states/ siblings for every data-bearing component.
3. Add the route shell in src/pages/ that renders the screen.
4. Use useMotionPresets() for any transitions (see mobile-motion-patterns).
5. pnpm --filter @agenta/mobile lint && pnpm --filter @agenta/mobile types:check.
