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 | $0.00000 | $0.01335 |
| Opus 5 | $0.00000 | $0.00668 |
| Sonnet 5 | $0.00000 | $0.00267 |
| Haiku 4.5 | $0.00000 | $0.00134 |
Grade A, and why
feature-settings 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Feature: Settings — Rules
What Is Already Implemented — Check Before Building
| Capability | Status |
|---|---|
| Haptic feedback toggle (persisted) | ✅ hapticFeedbackStateNotifierProvider |
| Prevent screen sleep / wakelock (persisted) | ✅ wakelockStateNotifierProvider |
| Generic toggle row widget (not persisted) | ✅ SwitchRowWidget |
Toggle wired to any CacheBoolStateNotifier |
✅ CacheBoolRowWidget |
| Dark / Light mode toggle row | ✅ ThemeRowWidget |
| Auto-haptic on list row tap | ✅ Built into LabelRowWidget.copyToClipboard / openLink |
| Notification permission settings | ❌ Not in package — use app_settings package |
| Non-boolean persisted setting | ❌ Not in package — implement following ThemeStateNotifier pattern |
Before creating a new settings notifier or widget, verify whether the above already satisfies the requirement.

There is no domain or data layer — settings use the core CacheBoolStateNotifier directly.
Adding a New Boolean Setting
Extend CacheBoolStateNotifier with a unique key and default value:
class MyFeatureStateNotifier extends CacheBoolStateNotifier {
MyFeatureStateNotifier({required super.getBoolUsecase, required super.setBoolUsecase, required super.removeCacheUsecase})
: super(key: myFeatureKey(), defaultValue: true);
}
const _key = 'myFeature';
String myFeatureKey() => kDebugMode ? '${_key}Debug' : _key;
final myFeatureStateNotifierProvider =
StateNotifierProvider<MyFeatureStateNotifier, bool>(
(ref) => MyFeatureStateNotifier(
getBoolUsecase: ref.read(getBoolUsecaseProvider),
setBoolUsecase: ref.read(setBoolUsecaseProvider),
removeCacheUsecase: ref.read(removeCacheUsecaseProvider),
),
);
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.

feature-settings is a cursor rule published in the GitHub repository sampaio-tech/flutter-core-modules (2 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,335 tokens. 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.
