Add a list+create page to a React app (clients/admin or clients/dashboard) — API module, page, lazy route, (admin) permission gate, Playwright test.

What it does

Add React Page is an agent skill from fullstackhero/dotnet-starter-kit. Add a list+create page to a React app (clients/admin or clients/dashboard) — API module, page, lazy route, (admin) permission gate, Playwright test. Use when adding any frontend screen. See .agents/rules/frontend/.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Project scaffolding and React components. It works with React and Playwright. The repository describes itself as: Production Grade Cloud-Ready .NET 10 Starter Kit (Web API + React Client) with Multitenancy Support, and Clean/Modular Architecture that saves roughly 200+ Development Hours! All… The licence is MIT.

When your agent uses it

  • Adding any frontend screen
  • Tasks that involve Project scaffolding
  • Tasks that involve React components

Example prompts

  • “/add-react-page”

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. API module (src/api/{resource}.ts)
  2. Page (src/pages/{area}/...tsx, named export)
  3. Mutation (race-safe mutate(arg))
  4. Register the route (routes.tsx)
  5. (admin only) mirror the permission
  6. Playwright test (tests/{area}/{resource}.spec.ts)
  7. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 0bd98e3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Add React Page loads about 1.5k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 335 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Add React Page

The frontend slice. Read .agents/rules/frontend/shared.md plus the app file (frontend/admin.md / frontend/dashboard.md) — the two apps deliberately diverge:

admin (operator)dashboard (tenant)
Query paramsPascalCase (PageNumber, Search)camelCase (pageNumber, search)
PagedResponse<T>import from @/lib/api-typesre-declare inline in the api module
Path constantconst BASE = "/api/v1/..."inline the full path per call
Formsreact-hook-form + zodhand-rolled controlled inputs (no RHF/zod)
List + createseparate routed pages (list.tsx, create.tsx)one file with <Dialog> editors
Route wrapper<RouteGuard perms={[…]}>withSuspense(<X/>) (no permission gate)
Permissionsmirror in src/lib/permissions.tsfetched from GET /identity/permissions (not JWT); nav gating via perm/anyPerm in nav-data.ts; no route guard — server 403 backstops

Shared everywhere: types are hand-written (no codegen); apiFetch<T> from @/lib/api-client; cn() from @/lib/cn; env.apiBase from runtime /config.json; CVA components/ui + components/list primitives; Tailwind v4 CSS-first (tokens in src/styles/globals.css); toast from sonner; pages are named exports; placeholderData: keepPreviousData (v5).

Step 1 — API module (src/api/{resource}.ts)

Hand-write the DTO/param/input types and thin apiFetch functions.

ts
// admin
import { apiFetch } from "@/lib/api-client";
import type { PagedResponse } from "@/lib/api-types";
const BASE = "/api/v1/{module}/{resources}";

export type {Resource}Dto = { id: string; name: string; /* … */ };

export async function search{Resources}(p: { pageNumber?: number; search?: string } = {}) {
  const q = new URLSearchParams();
  q.set("PageNumber", String(p.pageNumber ?? 1));
  q.set("PageSize", "10");
  if (p.search?.trim()) q.set("Search", p.search.trim());
  return apiFetch<PagedResponse<{Resource}Dto>>(`${BASE}/search?${q}`);
}
export async function create{Resource}(input: Create{Resource}Input) {
  return apiFetch<{ id: string }>(BASE, { method: "POST", body: JSON.stringify(input) });
}

(dashboard: inline type PagedResponse<T> = …, inline the path, camelCase params, mutations often return Promise<string>.)

Step 2 — Page (src/pages/{area}/...tsx, named export)

tsx
export function {Resource}ListPage() {
  const [search, setSearch] = useState("");           // debounce → reset page to 1 on change
  const [pageNumber, setPage] = useState(1);
  const query = useQuery({
    queryKey: ["{resources}", { pageNumber, search }],   // hierarchical; params object last
    queryFn: () => search{Resources}({ pageNumber, search: search || undefined }),
    placeholderData: keepPreviousData,
  });
  // render with components/ui/* + components/list/* (admin: PageHeader/Field…; dashboard: Entity* family)
}

Step 3 — Mutation (race-safe mutate(arg))

Pass per-call data through mutate(arg); read it from the callback variables — never from a closed-over render variable.

tsx
const qc = useQueryClient();
const createMut = useMutation({
  mutationFn: (input: Create{Resource}Input) => create{Resource}(input),
  onSuccess: () => { toast.success("Created"); qc.invalidateQueries({ queryKey: ["{resources}"] }); },
  onError: (e) => toast.error(e instanceof ApiRequestError ? e.message : "Failed"),
});
// admin: const form = useForm({ resolver: zodResolver(schema) });  form.handleSubmit(v => createMut.mutate(v))
// dashboard: controlled useState fields; onSubmit(e){ e.preventDefault(); createMut.mutate(payload); }

If you need to track the in-flight item (e.g. a per-row busy state), use onMutate: (arg) => setBusyId(arg) reading the mutate(arg) value (pattern: admin/src/pages/settings/sessions.tsx).

Step 4 — Register the route (routes.tsx)

tsx
const {Resource}ListPage = lazyNamed(() => import("@/pages/{area}/list"), "{Resource}ListPage");
// admin — under AppShell.children, gated:
{ path: "{resources}", element: <RouteGuard perms={[{Module}Permissions.{Resources}.View]}><{Resource}ListPage /></RouteGuard> },
// dashboard — under AppShell.children, suspense only:
{ path: "{area}/{resources}", element: withSuspense(<{Resource}ListPage />) },

Step 5 — (admin only) mirror the permission

Add the constant to src/lib/permissions.ts ({Module}Permissions.{Resources}.View = "Permissions.{Resources}.View"), and a PERMISSION_CATALOG entry if it belongs in the Role editor. See add-permission.

Step 6 — Playwright test (tests/{area}/{resource}.spec.ts)

ts
test.beforeEach(async ({ page }) => {
  // admin: seedAuthedSession(page, { ...TEST_USER, permissions: [...ADMIN_PERMS] }); await installAdminShellMocks(page);
  // dashboard: await seedAuthedSession(page, TEST_USER); await installShellMocks(page);
  await mockJsonResponse(page, "**/api/v1/{module}/{resources}**", paged([SAMPLE]));   // page mocks AFTER shell mocks
});

Use mockProblemDetails(...) for error states. Dashboard: scope row assertions with .last() / dialog scoping (lists render mobile + desktop copies → strict-mode double match).

Step 7 — Verify

bash
cd clients/{app} && npm run lint && npm run test:e2e

Checklist

  • API module: hand-written types, apiFetch, correct param casing per app (Pascal=admin, camel=dashboard)
  • Page is a named export; useQuery key hierarchical + placeholderData: keepPreviousData
  • Mutation passes data via mutate(arg), invalidates in onSuccess
  • Route via lazyNamed; admin wraps in <RouteGuard perms>, dashboard in withSuspense
  • (admin) permission mirrored in lib/permissions.ts
  • Playwright test: seed + shell mocks + page mocks; lint + test:e2e green
