A guide for building mobile apps with Flutter, React Native, or native Swift for iPhone and iPad. It also covers Android apps and mobile features such as cameras, location, notifications, and offline use.

Use it to build or change mobile screens, widgets, state management, camera or GPS features, push notifications, offline behavior, and mobile tests.

It helps handle mobile-specific screens, device features, app structure, performance, and testing instead of treating a mobile app like a website.

oma-mobile — Skill for Claude Code and Codex by first-fluke

About the project

oh-my-agent is a harness for checking whether coding agents actually completed their work by verifying tests, required artifacts, independent reviews, and recorded decisions. It is used across multiple agent runtimes to make workflow results auditable instead of relying on an agent's own report. The catalogue add-ons provide parts of its skills, agents, hooks, MCP integrations, instructions, and plugins.

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.

Any agent

npx skills add first-fluke/oh-my-agent --skill oma-mobile

Clone the repo

git clone --depth 1 https://github.com/first-fluke/oh-my-agent

Made for: Claude Code, Codex.

Or install oma, the plugin that ships this one along with the rest of its 37 skills, 12 agents, 4 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.02522
Opus 5.5	$0.00013	$0.01009
Sonnet 5.5	$0.00007	$0.00504
Haiku 4.5	$0.00003	$0.00252

Security

Grade A, and why

oma-mobile 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (variants/react-native/api-template.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Mobile Agent - Cross-Platform Mobile Specialist

Scheduling

Goal

Build, modify, and verify cross-platform mobile application features with clean architecture, platform-appropriate UI, state management, performance, and E2E coverage.

Intent signature

User asks for mobile app, Flutter, Dart, React Native, iOS, Android, Jetpack Compose, Kotlin, Riverpod, widgets, camera, GPS, push notifications, or offline-first work.
User needs native or cross-platform mobile behavior rather than web frontend work.

When to use

Building native mobile applications (iOS + Android)
Mobile-specific UI patterns
Platform features (camera, GPS, push notifications)
Offline-first architecture

When NOT to use

Web frontend -> use Frontend Agent
Backend APIs -> use Backend Agent

Expected inputs

Target screen, widget, feature, platform capability, or mobile flow
Existing app architecture, state management pattern, API contract, and platform constraints
Test expectations for unit, widget, integration, or Maestro E2E coverage

Expected outputs

Mobile code changes in domain, data, presentation, platform, or test files
UI aligned with Material Design 3 and iOS HIG as applicable
Verification results from mobile checks and critical-flow tests

Dependencies

Flutter/Dart, React Native, Swift, or Kotlin/Gradle toolchain as detected from the project
Riverpod/Bloc, Dio, Hilt, Ktor, platform SDKs, and Maestro where applicable
resources/execution-protocol.md, examples, snippets, checklist, and screen template

Control-flow features

Branches by platform, state management pattern, offline requirement, native permission, and test level
Reads and writes mobile codebase files
May call build, test, simulator, emulator, or E2E commands

Structural Flow

Entry

Identify target platform(s), screen/feature, architecture layer, and state boundary.
Inspect existing mobile patterns and dependencies.
Determine test level and verification environment.

Files

What ships with it

25 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
