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 5.1 | $0.00034 | $0.01861 |
| Opus 5.5 | $0.00014 | $0.00744 |
| Sonnet 5.5 | $0.00007 | $0.00372 |
| Haiku 4.5 | $0.00003 | $0.00186 |
Grade A, and why
flutter-embedding-native-views 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.

Platform Views Architecture
Platform Views allow embedding native views (Android, iOS, macOS) directly into a Flutter application, enabling the application of transforms, clips, and opacity from Dart.
Android Implementations (API 23+)
Choose the appropriate implementation based on your performance and fidelity requirements:
- Hybrid Composition: Renders Flutter content into a texture and uses
SurfaceFlingerto compose both.- Pros: Best performance and fidelity for Android views.
- Cons: Lowers overall application FPS. Certain Flutter widget transformations will not work.
- Texture Layer (Texture Layer Hybrid Composition): Renders Platform Views into a texture. Flutter draws them via the texture and renders its own content directly into a Surface.
- Pros: Best performance for Flutter rendering. All transformations work correctly.
- Cons: Quick scrolling (e.g., WebViews) can be janky.
SurfaceViewis problematic (breaks accessibility). Text magnifiers break unless Flutter is rendered into aTextureView.
iOS & macOS Implementations
- iOS: Uses Hybrid Composition exclusively. The native
UIViewis appended to the view hierarchy.- Limitations:
ShaderMaskandColorFilteredwidgets are not supported.BackdropFilterhas composition limitations.
- Limitations:
- macOS: Uses Hybrid Composition (
NSView).- Limitations: Not fully functional in current releases (e.g., gesture support is unavailable).
Performance Mitigation
Mitigate performance drops during complex Dart animations by rendering a screenshot of the native view as a placeholder texture while the animation runs.
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.

flutter-embedding-native-views is a skill published in the GitHub repository build-with-dhiraj/ai-workflow-framework-portability-kit (5 stars, last pushed 21d ago), licensed MIT. It adds 34 tokens to every session and 1,861 once invoked, about $0.0001 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 2026-09-21.
