This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Admin webapp for arcadia-core. Built on the Crema design system, themed with Skyrise, started from the Vibespace starter.
This file is a quick map, not a duplication of upstream docs.

## What Arcadia Admin is

- **Arcadia Admin** is the operator/admin UI for [arcadia-core](../reference/arcadia-app), a multi-tenant Phoenix backend. Surfaces tenant management, user/role admin, billing, audit logs, storage configs, scheduled tasks, feature flags, and platform monitoring on top of arcadia's `/api/v1` and `/admin/*` endpoints.
- **Cloned from** [Vibespace](../vibespace) — the starter for webapps in this style. Vibespace and Skyrise are the upstream sources of truth for the shell and the theme; don't backport arcadia-admin-specific changes into Vibespace unless they're broadly applicable.
- **Backend reference** lives at `../reference/arcadia-app/`. Treat it as read-only documentation — it's the Phoenix umbrella app that owns the OpenAPI spec, controllers, schemas, and seed data. Spec is regenerated from a running arcadia at `http://localhost:4000/api/openapi` via `node ../lib-arcadia-client/scripts/sync-spec.mjs` (run from this directory).
- **Skyrise** (`lib-theme-skyrise`) is the canonical theme — premium AI-first glass, iridescent body, vivid text, Apple-spring motion. Theme tweaks belong upstream in Vibespace + Skyrise, not here.
- The brand string lives in **one place**: `app/lib/identity.ts` (`useBrand()` / `getBrand()`). Don't hardcode "Arcadia Admin" in components, page titles, or copy.

## Arcadia integration (already wired)

- **`<ArcadiaProvider>`** in `app/root.tsx` reads `VITE_ARCADIA_URL` (default `http://localhost:4000`) and `VITE_ARCADIA_TENANT` (default `default`). `getToken` reads `arcadia_access_token` from `sessionStorage`. `onUnauthorized` clears the token.
- **`useArcadiaClient()`** for typed/generic HTTP. `arcadia.typed.GET("/api/v1/...")` infers paths from the generated `paths` type; `arcadia.GET<T>(path)` is the generic escape hatch for spec-incomplete endpoints.
- **Login** — `app/routes/login.tsx` renders `<LoginForm>` from `@crema/arcadia-auth-ui`. Successful login writes tokens via `persistFromArcadiaLogin()` in `app/lib/session.ts`, which preserves the existing `Session` shape used by `useUser` / `AppShell`.
- **Realtime** — supported by the lib but not enabled at the provider here; pass `enableRealtime` + `userId` to opt in.
- **Search admin sidecar** — the `/search` route (`app/routes/search.tsx`) calls arcadia-search's privileged `/admin/*` surface (default `127.0.0.1:7801`) via `app/lib/search-admin.ts`. Configured by `VITE_ARCADIA_SEARCH_ADMIN_URL` + `VITE_ARCADIA_SEARCH_ADMIN_TOKEN`; the token must match `ADMIN_TOKEN` on the search box. See `arcadia-search/README.md` § *Admin sidecar*.

## Scripts

- `npm run dev` — Vite dev server (React Router 7).
- `npm run build` — production build (`react-router build`).
- `npm run start` — serve the built app (`react-router-serve ./build/server/index.js`).
- `npm run typecheck` — `react-router typegen && tsc`. See gotcha below; may crash.
- `start.sh` / `stop.sh` — repo's preferred way to run/stop the dev server in the background.

- `npm run test` — Vitest run (vibespace-inherited setup; jsdom + @testing-library/react).

## App layout (`app/`)

- `routes/` + `routes.ts` — file-based React Router 7 routes (Overview, Resources, Activity, Assistant, Library, Settings).
- `components/layout/` — `app-shell.tsx` (rail + appbar + avatar dropdown), `appbar.tsx`, `theme-toggle.tsx`. **Template code, not a lib** — fork it freely.
- `components/assistant/message-body.tsx` — markdown rendering for assistant replies + action-block pill.
- `components/scripts-dialog.tsx` — ⌘⇧P script runner UI.
- `lib/identity.ts` — `useBrand()` / `useUser()` (default stubs; swap for real session).
- `lib/llm-settings.ts` — persisted LLM endpoint + context budget config.
- `lib/page-meta.ts`, `lib/utils.ts` — small helpers.
- `app.css` — Tailwind v4 entrypoint; theme `@import` first, then tailwind, then per-lib `@source` lines.
- `root.tsx` — `ToastProvider` + `CommandBusProvider` wrap point.

## What this is

- React Router 7 + Tailwind v4 SPA.
- Hybrid traditional + AI-first scaffold. Most surfaces are normal; the
  Assistant surface is wrapped in `<AppShell theme="skyrise">` for the
  AI-styled mood (warm cream + ink-blue + serif prose).
- Built on Crema libs (`@crema/*-ui`) cloned as **sibling directories**, not
  npm packages.
- The `@crema/action-bus` lib is the foundation: anything (LLM, scripts,
  WebSocket, tests) can drive the UI via `[data-action]`-tagged elements. See
  `docs/AI_FIRST.md`.

## Crema system (authoritative)

- **Lib catalog:** see `docs/LIBS.md` for a snapshot of every `@crema/*-ui` lib
  (the ones wired into this project AND the ones available to add). Before
  building any UI primitive, check there first — there's a good chance a lib
  already does it. Refresh the snapshot with `npm run sync-libs`.
- **Each `@crema/*-ui` lib is its own git repo** at
  `https://git.sky-ai.com/CremaUIStudio/lib-<name>-ui`, cloned as a sibling
  of this app. Edits to lib code commit to that lib's repo, not this one.
- **Themes** (`lib-theme-*`) are CSS-only token files at the same Gitea org.
- **Live manifest** (which `docs/LIBS.md` is generated from) is the
  `crema-manifest` repo. Gitea's raw-file HTTP URL 404s; clone instead:
  ```bash
  git clone --depth 1 https://git.sky-ai.com/CremaUIStudio/crema-manifest.git /tmp/crema-manifest
  cat /tmp/crema-manifest/manifest.json
  ```

## Adding a lib after scaffold

Prefer the CLI:

```bash
crema add <lib-name>      # e.g. crema add status-ui chart-ui
```

It clones the lib as a sibling, adds the `@source` line to `app/app.css`, and wires `tsconfig.json` paths.

Manual fallback (3 edits):
1. Clone `lib-<name>-ui` as a sibling.
2. `app/app.css` → add `@source "../../lib-<name>-ui/src";`
3. `tsconfig.json` paths → add `"@crema/<name>-ui": ["../lib-<name>-ui/src/index.tsx"]` and the `/*` variant.

Then run `npm run sync-libs` to refresh `docs/LIBS.md`.

## Theme convention

- A single theme (`lib-theme-skyrise` by default) is loaded via `:root` in
  `app/app.css`, **first** so its embedded `@import url(...)` Google Fonts
  declarations resolve to the top of the output.
- Themes are self-contained: tokens **and** their font `@import url(...)` ship
  inside the theme's CSS file.
- Per-surface alt themes can be scoped via `[data-theme="<name>"]` and applied
  with the shell's `theme` prop. The Assistant route already does this:
  `<AppShell title="Assistant" theme="skyrise">…</AppShell>`.
- Components reference tokens (`var(--card)`, `bg-card`, etc.), never hex
  values. See `app/components/layout/THEME_CONTRACT.md` for the full token list
  any theme must implement.
- Assistant prose uses `var(--font-ai-prose)`. Don't hard-code font families.

## Coding conventions

- `lib-*-ui` components use **inline styles with CSS variables** (`style={{ background: "var(--card)", color: "var(--foreground)" }}`), not Tailwind classes. App routes use Tailwind freely with theme-variable utilities (`bg-card`, `text-muted-foreground`).
- Every shadcn-style component has a `[data-slot="..."]` attribute — themes target these for surface treatment overrides. Preserve them when editing libs.
- Lib `src/index.tsx` files start with `// PURPOSE:` and `// EXPORTS` blocks, plus `"use client"` at the top. Maintain the header.
- Don't hardcode colors. Use tokens.

## Polyrepo gotchas

- `git status` at this app's root only shows app changes. To see lib edits, `cd ../lib-<name>-ui && git status`.
- Each repo commits and pushes separately.
- Don't bundle lib edits into app commits.
- Sibling libs already cloned next to this app include the full Crema set (`lib-chat-ui`, `lib-table-ui`, `lib-chart-ui`, `lib-theme-skyrise`, etc.) — check `../lib-*` before adding anything new.

## Marker contract (CLI-managed regions)

This repo was scaffolded from `create-crema-app`, which patches marker comments. Preserve them when editing:

| File | Marker |
| --- | --- |
| `tsconfig.json` | `"// CREMA:PATHS"` |
| `app/app.css` | `/* CREMA:SOURCES */` |
| `app/routes.ts` | `// CREMA:ROUTES` |
| `app/components/layout/app-shell.tsx` | `// CREMA:NAV-ICONS`, `// CREMA:NAV-ITEMS` |
| `app/root.tsx` | `// CREMA:PROVIDERS-IMPORTS`, `/* CREMA:PROVIDERS-WRAP-OPEN */`, `/* CREMA:PROVIDERS-WRAP-CLOSE */` |

## Common tasks

- **Run dev:** `npm run dev`
- **Add a UI primitive:** check the manifest first; if it exists, `crema add <lib>`; if not, build inline and consider whether it should become a lib.
- **Add a route:** create the file under `app/routes/`, register in `app/routes.ts`, add a nav entry in the sidenav (traditional) or chat shell (AI).
- **Switch theme on a route:** pass `theme="<name>"` to `<AppShell>`. Default (no prop) uses the `:root` theme.
- **Add a script:** drop a `.script` file into `public/scripts/`, register it in `KNOWN_SCRIPTS` in `app/components/scripts-dialog.tsx` if you want it in the dialog list, or invoke programmatically with `runScript("<name>")`.
- **Make a component scriptable:** add `data-action="<id>"`. The bus auto-discovers it.

## Known gotchas

- `npm run typecheck` may crash with a TypeScript internal error — pre-existing in the Crema toolchain. There's no test runner here, so rely on careful reads + dev server.
- Vite "Outdated Optimize Dep" 504s after editing `vite.config.ts` or `tsconfig.json`: stop dev, `rm -rf node_modules/.vite`, restart, hard-reload.
- After editing a sibling lib's exports, the dev server sometimes needs a manual restart to pick up the new types.
