What it does
Senior Mobile is an agent skill from borghei/Claude-Skills. Use when the user asks to "build a mobile app", "scaffold React Native project", "create SwiftUI views", "set up Jetpack Compose", "optimize mobile performance", "configure Expo Router navigation", "implement offline-first storage", "submit to App Store", or "profile mobile rendering". Expert mobile development covering iOS (Swift/SwiftUI), Android (Kotlin/Compose), React Native, and Flutter for native and cross-platform applications.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts and reference files (for example `REFERENCE.md`, `references/ios-android-patterns.md` and `references/mobile-security-guide.md`).
It sits in Mobile, covering Cross-platform mobile apps, iOS development and Android development. It works with React Native, SwiftUI, Flutter and Android. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
When your agent uses it
- The user asks to build a mobile app
- Scaffold React Native project
- Create SwiftUI views
- Set up Jetpack Compose
Example prompts
- “build a mobile app”
- “scaffold React Native project”
- “create SwiftUI views”
- “/senior-mobile”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 4a698e8. 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
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Senior Mobile loads about 1.9k tokens when it runs, and up to ~20k if it reads all its reference files. Until then it costs about 113 tokens; SKILL.md has 724 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

Senior Mobile Developer
Expert mobile application development across iOS, Android, React Native, and Flutter — scaffolding production projects, building MVVM features (SwiftUI, Jetpack Compose, Expo Router), static performance analysis, and App Store / Play Store submission.
Keywords
mobile, ios, android, react-native, flutter, swift, kotlin, swiftui, jetpack-compose, expo-router, zustand, app-store, performance, offline-first
Core Capabilities
- Project scaffolding — production-ready structure, navigation, and state management for React Native (Expo Router), Flutter, iOS native (SwiftUI), and Android native (Jetpack Compose).
- Platform selection — decision matrix across native iOS/Android, React Native, and Flutter by language, performance, and code-sharing.
- Feature architecture — MVVM patterns: SwiftUI
@MainActorViewModels, Compose sealedUiState+StateFlow, Zustand stores. - Performance optimization — static analysis of image assets, re-renders, memory leaks, bundle size, plus FlatList/RecyclerView/collection-view tuning.
- Store submission — metadata, keywords, privacy labels, age ratings, and submission checklists for both stores.
When to Use
- Starting a new mobile app and choosing a platform.
- Building a SwiftUI, Jetpack Compose, or React Native feature with clean architecture.
- Diagnosing and fixing mobile performance issues.
- Preparing an App Store / Play Store submission.
Clarify First
Before scaffolding, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- Platform — react-native / flutter / ios-native / android-native (
--platform; an entirely different scaffold) - State management — e.g. zustand (
--state; changes the generated architecture) - Task — new project scaffold vs store-listing metadata vs performance analysis (selects
mobile_scaffold/store_metadata_generator/app_performance_analyzer)
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
Tools
| Tool | Purpose | Command |
|---|---|---|
mobile_scaffold.py | Scaffold a project for react-native, flutter, ios-native, or android-native | python scripts/mobile_scaffold.py MyApp --platform react-native --state zustand |
store_metadata_generator.py | Generate App Store / Play Store listing metadata | python scripts/store_metadata_generator.py --app-name FitTrack --category health --features "workout,tracking" |
app_performance_analyzer.py | Static performance analysis (score, issues, bundle estimate) | python scripts/app_performance_analyzer.py ./my-app --platform react-native |
References
Load the reference that matches the task — keep this file lean and pull detail on demand:
- references/workflows.md — the platform decision matrix and all five end-to-end workflows (React Native scaffold, SwiftUI feature, Jetpack Compose feature, performance optimization, store submission) with SwiftUI/Compose code examples. Read when executing any workflow.
- references/tool-reference.md — full parameter tables, examples, and output formats for the three scripts. Read when running the scripts.
- references/troubleshooting-and-success.md — the build/render/submission troubleshooting table and the success-criteria bar. Read when debugging or validating quality.
- references/react-native-patterns.md — production React Native: navigation, state management, performance, testing, native modules, OTA updates. Read for deep RN work.
- references/ios-android-patterns.md — native iOS/Android architecture, UI frameworks, concurrency, platform UX guidelines, and CI/CD. Read for deep native work.
- references/mobile-security-guide.md — secure storage, network security, authentication, code protection, and OWASP Mobile Top 10 compliance. Read when hardening an app.
- REFERENCE.md — extended code examples for the workflows above. Read when you need fuller worked code.

Scope & Limitations
This skill covers:
- Scaffolding production-ready mobile projects for React Native (Expo Router), Flutter, iOS native (SwiftUI), and Android native (Jetpack Compose).
- Static performance analysis including image asset sizing, re-render detection, memory leak patterns, and bundle size estimation.
- App Store and Play Store metadata generation including titles, keywords, privacy labels, age ratings, and submission checklists.
- Platform-specific architecture patterns (MVVM, state management, navigation).
This skill does NOT cover:
- Backend API development or server-side logic (see
senior-backendandsenior-fullstackskills). - CI/CD pipeline configuration for mobile builds and automated distribution (see
senior-devopsandrelease-orchestratorskills). - UI/UX design systems, accessibility auditing, or design token management (see
senior-frontendanddesign-auditorskills). - Runtime profiling with native tools (Xcode Instruments, Android Studio Profiler) -- the analyzer performs static code analysis only, not live device profiling.
Integration Points
| Skill | Integration | Data Flow |
|---|---|---|
senior-frontend | Shared component patterns, styling conventions, and responsive design principles for React Native web targets | Frontend design tokens and component APIs feed into mobile UI components |
senior-backend | API contract definitions, authentication flows, and data models consumed by mobile clients | Backend OpenAPI specs define mobile service layer interfaces |
senior-devops | Build pipelines, code signing automation, and deployment workflows for mobile releases | Mobile build artifacts flow into CI/CD pipelines for TestFlight / Play Console distribution |
senior-qa | Test strategy alignment, device matrix coverage, and E2E testing patterns for mobile screens | QA test plans drive device coverage; mobile scaffold includes test directory structure |
senior-security | Secure storage patterns (Keychain/Keystore), certificate pinning, and data encryption for mobile apps | Security requirements inform Keychain helper implementation and network client configuration |
release-orchestrator | Version bumping, changelog generation, and coordinated release across iOS and Android | Release metadata and version info flow from orchestrator into store submission workflow |
