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 | $0.00052 | $0.01439 |
| Opus 5 | $0.00026 | $0.00720 |
| Sonnet 5 | $0.00010 | $0.00288 |
| Haiku 4.5 | $0.00005 | $0.00144 |
Grade A, and why
flutter-setup-localization 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.

Internationalizing Flutter Applications
Contents
Core Concepts
Flutter handles internationalization (i18n) and localization (l10n) via the flutter_localizations and intl packages. The standard approach uses App Resource Bundle (.arb) files to define localized strings, which are then compiled into a generated AppLocalizations class for type-safe access within the widget tree.
Setup Workflow
Copy and track this checklist when initializing internationalization in a Flutter project:
- Task Progress
- 1. Add dependencies to
pubspec.yaml. - 2. Enable the
generateflag. - 3. Create the
l10n.yamlconfiguration file. - 4. Configure
MaterialApporCupertinoApp.
- 1. Add dependencies to
1. Add Dependencies
Add the required localization packages to the project. Execute the following commands in the terminal:
flutter pub add flutter_localizations --sdk=flutter
flutter pub add intl:any
Verify your pubspec.yaml includes the following under dependencies:
dependencies:
flutter:
sdk: flutter
flutter_localizations:
sdk: flutter
intl: any
2. Enable Code Generation
Open pubspec.yaml and enable the generate flag within the flutter section to automate localization tasks:
flutter:
generate: true
3. Create Configuration File
Create a new file named l10n.yaml in the root directory of the Flutter project. Define the input directory, template file, and output file:
arb-dir: lib/l10n
template-arb-file: app_en.arb
output-localization-file: app_localizations.dart
synthetic-package: true
4. Configure the App Entry Point
Import the generated localizations and the flutter_localizations library in your main.dart. Inject the delegates and supported locales into your MaterialApp or CupertinoApp.
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-setup-localization is a skill published in the GitHub repository flutter/agent-plugins (2,895 stars, last pushed 3d ago), licensed BSD-3-Clause. It adds 52 tokens to every session and 1,439 once invoked, about $0.0003 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.
