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 | $0.00048 | $0.00544 |
| Opus 5 | $0.00024 | $0.00272 |
| Sonnet 5 | $0.00010 | $0.00109 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
flutter-getx-state-management 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 9d 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.

Implementation Guidelines
- Controllers: Extend
GetxController. Store logic and state variables here. - Reactivity:
- Use
.obsfor observable variables (e.g.,final count = 0.obs;). - Wrap UI in
Obx(() => ...)to listen for changes. - For simple state, use
update()in controller andGetBuilderin UI. - Dependency Injection:
- Bindings: Use
Bindingsclass to decouple DI from UI. - Lazy Load: Prefer
Get.lazyPut(() => Controller())in Bindings. - Lifecycle: Let GetX handle disposal. Avoid
permanent: true. - Hooks: Use
onInit(),onReady(),onClose()instead ofinitState/dispose. - Architecture: Use
get_clifor modular MVVM (data, models, modules).
Anti-Patterns
- Ctx in Logic: Pass no
BuildContextto controllers. - Inline DI: Avoid
Get.put()in widgets; use Bindings +Get.find. - Fat Views: Keep views pure UI; delegate all logic to controller.
Code Example
See references/controller-example.md for controller + view implementation pattern.

Controller boundary
- Keep
BuildContextout of controllers. Use GetX services such asGet.snackbarfor controller-owned feedback and expose reactive state to the view.
Remediation anchors
- Remediation anchors: onInit, Obx, no BuildContext in the controller
What ships with it
2 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-getx-state-management is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (565 stars, last pushed 3d ago), licensed MIT. It adds 48 tokens to every session and 544 once invoked, about $0.0002 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 2026-09-03.
