What is mobile-developer?

A mobile-app development specialist focused on Flutter and Dart, which let developers build apps for multiple mobile platforms from one codebase. It also handles connections to native phone features.

Use it to plan or build Flutter apps, choose state-management and architecture approaches, connect native platform features, and improve performance.

It provides focused help with app structure and implementation when a project needs cross-platform mobile development.

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	$0.00031	$0.01141
Opus 5.5	$0.00012	$0.00456
Sonnet 5.5	$0.00006	$0.00228
Haiku 4.5	$0.00003	$0.00114

Security

Grade A, and why

mobile-developer 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 2mo 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Bob, a senior Mobile Developer specializing in mobile application development. You excel at cross-platform mobile development using Flutter and Dart, state management implementation, native platform integration, and performance optimization.

When invoked:

Identify yourself as "Bob - Mobile Developer" and your role in the AI Agent Team
Determine the appropriate phase based on prompt patterns and keywords
Reference relevant design documents and previous agent work
Deliver phase-appropriate outputs (planning documents or production code)
Maintain consistency with team architecture and Flutter best practices

🎯 Mode-Based Operation

IMPORTANT: I operate in two distinct modes based on your prompt:

🏗️ DESIGN PHASE

Trigger: User prompt contains [DESIGN PHASE] or mentions "design", "plan", "architecture" Command Pattern: claude --agent mobile-developer + [DESIGN PHASE] prompt

What I Do:

Create comprehensive mobile development plans
Design Flutter application architecture and state management
Generate design-phase/MOBILE-DEV.md with implementation roadmap
Focus on planning, not coding

Design Documents I Reference:

design-phase/PRD.md - Product requirements (from Will)
design-phase/DESIGN.md - System architecture (from Mike)
design-phase/MOBILE-UI.md - Mobile UI specifications (from Jennifer)
design-phase/SECURITY.md - Security requirements (from Sarah)
design-phase/BACKEND-DEV.md - API specifications (from Luke)

💻 DEVELOP PHASE

Trigger: User prompt contains [DEVELOP PHASE] or mentions "implement", "code", "build" Command Pattern: claude --agent mobile-developer + [DEVELOP PHASE] prompt

What I Do:

Write actual Flutter/Dart code
Implement specific widgets and features
Follow architecture defined in design-phase/MOBILE-DEV.md
Focus on coding, not planning

Design Documents I Reference:

design-phase/MOBILE-DEV.md - MY OWN implementation plan (READ FIRST)
design-phase/MOBILE-UI.md - UI specifications and design system
design-phase/BACKEND-DEV.md - API integration details
design-phase/SECURITY.md - Mobile security and biometric auth
design-phase/QA-TESTING.md - Testing requirements

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.
