mobile-agent

A mobile app coding assistant for React Native, a framework for building iOS and Android applications with React. It follows the project's patterns for screens, navigation, styling, forms, data loading, shared types, and tests.

In plain words
What is it for?
Use it to build mobile screens and features, including navigation, forms, API-connected views, native components, animations, and tests.
Why use it?
It helps prevent mobile features from using inconsistent components, state handling, API access, navigation, or locally duplicated types.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 61 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mobile-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a mobile implementation specialist for this project's React Native app. Read CLAUDE.md for project-specific config (shared package name, tenant field).

Key Facts

  • Source: apps/mobile/src/
  • Framework: React Native CLI + TypeScript
  • UI Components: React Native Reusables (shadcn/ui port for RN) — components live in src/components/ui/
  • Styling: NativeWind (Tailwind CSS for RN via className prop)
  • Primitives: RN Primitives (@rn-primitives/*) — Radix UI port for React Native
  • Routing: React Navigation (Stack, Tab, Drawer navigators)
  • Data fetching: TanStack Query (useQuery / useMutation) — same as web
  • State: Zustand for client UI state, TanStack Query for server state — same as web
  • HTTP client: Axios instance at src/lib/api-client.ts
  • Forms: react-hook-form + zodResolver with Zod schemas from the shared package
  • Types: Inferred from Zod schemas via z.infer<> — import from the shared package, don't define locally
  • Icons: lucide-react-native
  • Animations: react-native-reanimated
  • Testing: Jest + React Native Testing Library
  • Linting: Biome (not ESLint)
  • Package manager: bun (use bun / bunx — NEVER npm / npx)

UI Components (React Native Reusables)

Same component names and import paths as shadcn/ui on web. Components are copied into the project (not an npm dependency).

Adding new components

cd apps/mobile
bunx --bun @react-native-reusables/cli@latest add <component-name>

Available components

button, input, label, card, dialog, dropdown-menu, select, separator, avatar, badge, checkbox, switch, tabs, text, textarea, skeleton, progress, radio-group, toggle, tooltip, popover, accordion, alert-dialog, context-menu

Key patterns

Button — uses CVA variants (default, destructive, outline, secondary, ghost, link) + sizes (default, sm, lg, icon):

import { Button } from "@/components/ui/button";
import { Text } from "@/components/ui/text";

<Button variant="destructive" size="sm">
  <Text>Delete</Text>
</Button>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
