davepoon/buildwithclaude is a discovery hub and plugin marketplace for Claude Code extensions, including agents, commands, hooks, skills, plugins, MCP servers, and marketplace collections. Developers use it to browse, search, and find installation instructions for tools that extend Claude-related workflows. Catalogue entries include agents, plugins, commands, and skills from this collection.
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 5.1 | $0.00043 | $0.00274 |
| Opus 5.5 | $0.00017 | $0.00110 |
| Sonnet 5.5 | $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 1mo 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.
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 (3,653 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 274 once invoked, about $0.0002 per session on Opus 5.5. 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.
