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 | $0.00131 | $0.01274 |
| Opus 5 | $0.00066 | $0.00637 |
| Sonnet 5 | $0.00026 | $0.00255 |
| Haiku 4.5 | $0.00013 | $0.00127 |
Grade A, and why
implementing-flutter-bloc 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 11d 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.

BLoC State Management (v9.x)
Goal
Strict separation of UI from business logic via event-driven unidirectional data flow. Choose Cubit (lightweight, no events) for simple state, or full Bloc (events + transformers) for complex flows.
Process
1. Install Dependencies
dependencies:
flutter_bloc: ^9.1.1
equatable: ^2.0.5
bloc_concurrency: ^0.3.0 # For event transformers
dev_dependencies:
bloc_test: ^10.0.0
2. Choose Pattern
| Pattern | When to Use |
|---|---|
| Cubit | Simple state (toggle, counter, form validation) |
| Bloc | Event tracking, transformers, complex flows (login, search debounce) |
3A. Implement Cubit
class CounterState extends Equatable {
final int value;
const CounterState({required this.value});
@override
List<Object?> get props => [value];
}
class CounterCubit extends Cubit<CounterState> {
CounterCubit() : super(const CounterState(value: 0));
void increment() => emit(CounterState(value: state.value + 1));
void decrement() => emit(CounterState(value: state.value - 1));
}
3B. Implement Bloc
abstract class CounterEvent extends Equatable {
const CounterEvent();
@override
List<Object?> get props => [];
}
class CounterIncremented extends CounterEvent {}
class CounterDecremented extends CounterEvent {}
class CounterBloc extends Bloc<CounterEvent, CounterState> {
CounterBloc() : super(const CounterState(value: 0)) {
on<CounterIncremented>((e, emit) => emit(CounterState(value: state.value + 1)));
on<CounterDecremented>((e, emit) => emit(CounterState(value: state.value - 1)));
}
}
4. Provide to Widget Tree
MultiBlocProvider(
providers: [
BlocProvider(create: (context) => CounterCubit()),
BlocProvider(create: (context) => AuthBloc()),
],
child: MyApp(),
)
5. Consume State
| Widget | Use For |
|---|---|
BlocBuilder |
Rebuild UI on state changes |
BlocListener |
Side effects only (navigation, snackbars) |
BlocConsumer |
Rebuild + side effects together |
What ships with it
3 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.

implementing-flutter-bloc is a skill published in the GitHub repository Poorgramer-Zack/dart-expert-skills (7 stars, last pushed 1mo ago), licensed MIT. It adds 131 tokens to every session and 1,274 once invoked, about $0.0007 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 2026-08-31.
