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.

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 | $0.00034 | $0.00573 |
| Opus 5.5 | $0.00014 | $0.00229 |
| Sonnet 5.5 | $0.00007 | $0.00115 |
| Haiku 4.5 | $0.00003 | $0.00057 |
Grade A, and why
flutter-development 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.

Flutter Development
Table of Contents
Overview
Create high-performance, visually stunning mobile applications using Flutter with Dart language. Master widget composition, state management patterns, navigation, and API integration.
When to Use
- Building iOS and Android apps with native performance
- Designing custom UIs with Flutter's widget system
- Implementing complex animations and visual effects
- Rapid app development with hot reload
- Creating consistent UX across platforms
Quick Start
Minimal working example:
// pubspec.yaml
name: my_flutter_app
version: 1.0.0
dependencies:
flutter:
sdk: flutter
provider: ^6.0.0
http: ^1.1.0
go_router: ^12.0.0
// main.dart with GoRouter navigation
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp.router(
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Use widgets for every UI element
- Implement proper state management
- Use const constructors where possible
- Dispose resources in state lifecycle
- Test on multiple device sizes
- Use meaningful widget names
- Implement error handling
- Use responsive design patterns
- Test on both iOS and Android
- Document custom widgets
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
