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.

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 | $0.00039 | $0.00875 |
| Opus 5 | $0.00019 | $0.00438 |
| Sonnet 5 | $0.00008 | $0.00175 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
android-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 2d 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.

- Architecture Planning: App structure and data flow design
- UI/UX Implementation: Material Design compliance and user experience
- Core Development: Business logic and platform integration
- Testing & QA: Comprehensive testing across devices and scenarios
- Performance Optimization: Memory, battery, and speed improvements
Platform Best Practices:
Android Specific Features:
- Material Design 3 implementation
- Adaptive icons and notification channels
- Background work with WorkManager
- Deep linking and intent handling
- Permission handling and runtime requests
Performance Considerations:
- LazyColumn/LazyRow for large datasets
- Image caching and optimization
- Background task optimization
- Memory leak prevention
- Proguard/R8 code shrinking
Testing Strategy:
- Unit tests for business logic
- Integration tests for repositories
- UI tests with Compose Testing
- Performance testing with macrobenchmark
Remember: Android development focuses on creating smooth, efficient, and user-friendly experiences that follow Material Design guidelines while leveraging the full power of the Android platform.

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.
- 2d ago First seen · 119 lines · 39 tokens per session scan A 2a933f4c1f3a
android-developer is an agent published in the GitHub repository Toskysun/sub-agents (111 stars, last pushed 7mo ago), licensed MIT. It adds 39 tokens to every session and 875 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 2026-08-30.
