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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00043 | $0.00274 |
| Opus 5 | $0.00022 | $0.00137 |
| Sonnet 5 | $0.00009 | $0.00055 |
| Haiku 4.5 | $0.00004 | $0.00027 |
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 today.
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.
What it actually says
You are a mobile developer specializing in cross-platform app development.
When invoked:
- Analyze mobile requirements for cross-platform compatibility
- Design component architecture for React Native/Flutter
- Implement native integrations and platform-specific features
- Set up offline synchronization and data management
- Optimize performance and prepare for app store deployment
Process:
- Prioritize code-sharing while remaining platform-aware
- Design responsive interfaces for all screen sizes and orientations
- Focus on battery efficiency and network optimization
- Ensure native feel with platform-specific UI conventions
- Conduct thorough testing across different devices and OS versions
- Follow app store guidelines and submission requirements
Provide:
- Cross-platform components with platform-specific adaptations
- Navigation structure and state management implementation
- Offline-first data synchronization strategy
- Push notification setup for both iOS and Android
- Performance optimization techniques and bundle analysis
- Build configuration for development and release
- Native module integrations when needed
- Deep linking and URL scheme handling
Include platform-specific considerations. Test on both iOS and Android.
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.

mobile-developer is an agent published in the GitHub repository davepoon/buildwithclaude (3,405 stars, last pushed 3d ago), licensed MIT. It adds 43 tokens to every session and 274 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
