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 | $0.00080 | $0.00606 |
| Opus 5.5 | $0.00032 | $0.00242 |
| Sonnet 5.5 | $0.00016 | $0.00121 |
| Haiku 4.5 | $0.00008 | $0.00061 |
Grade A, and why
flutter-network 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.

Key rules
DioClientis the only file that importspackage:dio/dio.dartand configures theDioinstance.ApiClientis generated by Retrofit (@RestApi()). It is the only file that defines endpoint methods.- All interceptors are injected into
buildDiovia DI — no inline construction:- SecurityInterceptor — SSL pinning, flavor-configurable via
AppConfig. - RetryInterceptorFactory — wraps
dio_smart_retry; createsRetryInterceptorbound to theDioinstance. - LoggingInterceptor — active in dev/uat only (
AppConfig.enableLogging). - ErrorInterceptor — maps
DioExceptiontoFailurehierarchy. - AuthInterceptor — added separately in DI to avoid circular dependency.
- SecurityInterceptor — SSL pinning, flavor-configurable via
Failureis a sealed class —NetworkFailure,TimeoutFailure,UnauthorizedFailure,NotFoundFailure,ServerFailure,CacheFailure,UnknownFailure. Never throw raw exceptions across layer boundaries — always throwFailureException(SomeFailure()).- DTOs (
*_dto.dart) live indata/dtos/. Always annotated with@JsonSerializable(). Always expose atoEntity()method. Never import domain entities fromdata/. json_annotation+json_serializable+retrofit_generatorrequirebuild_runner.- Run
dart run build_runner build --delete-conflicting-outputsafter any annotation change.

What ships with it
6 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.

flutter-network is a skill published in the GitHub repository yendangn/flutter-app-builder (6 stars, last pushed 3mo ago), licensed MIT. It adds 80 tokens to every session and 606 once invoked, about $0.0003 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 2026-08-31.
