FlutterKit: Skill for Codex

.agents/skills/fkit-feature/SKILL.md

fkit-feature is a skill for Codex from Joker-x-dev/FlutterKit. It costs 67 tokens per session (620 once invoked), scanned A, original, MIT.

A skill for creating, changing, and restructuring FlutterKit features and pages. FlutterKit is a Flutter application framework with separate parts for screens, logic, state, dependencies, navigation, and translations.

In plain words
What is it for?
Use it to add or refactor business modules and screens, connect routes and translations, choose the right page base class, add previews and tests, and check the affected code.
Why use it?
It helps keep new or changed pages consistent with the project's architecture and avoids putting responsibilities in the wrong layer.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is Joker-x-dev/FlutterKit's own configuration. It tells Codex how to work on FlutterKit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything FlutterKit configures →

Token cost

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.

Security

Grade A, and why

fkit-feature 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 2mo 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.

必读资料

先阅读仓库根目录 AGENTS.md，再按任务读取：

  • docs/flutter-kit/业务功能/index.md
  • docs/flutter-kit/业务功能/structure.md
  • docs/flutter-kit/业务功能/create-page.md
  • docs/flutter-kit/业务功能/templates.md
  • 当前层对应的 view.md、logic.md、state.md、binding.md
  • docs/flutter-kit/框架核心/base.md 及所选父类专题

涉及 UI、导航、数据或预览时继续遵守对应 FKit Skill 与项目文档。

工作流

  1. 检查目标 Feature、相邻页面、路由和测试，确认现有命名与依赖方式。
  2. 根据数据形态选择普通、网络、分页、刷新或 Tab 父类，禁止在普通页面复制父类状态机。
  3. 按真实复杂度创建 View、Logic、State、Binding；不要为了目录完整创建空文件。
  4. 将单页模型、静态数据、小型 Widget、Skeleton 和行为留在页面附近。同一模块多页面复用时才提升到模块级按需目录，跨 Feature 复用时才进入 Core。
  5. 让 View 只布局、订阅和转发事件；让 Logic 处理生命周期、Repository/Service、状态与导航；让 State 只保存展示状态；让 Binding 只注册依赖。
  6. 将用户可见文案写入模块 localization/，并接入路由、Navigator 和 Preview。
  7. 补充对应测试，检查 Feature 未直接依赖其他 Feature 的内部实现。

关键约束

  • Feature data/ 只保存模块共享静态配置、展示数据或提供器，不创建第二套 Repository/DataSource。
  • Repository 字段使用完整领域名称，例如 _userInfoStoreRepository，不用 _repository。
  • 模块 Service 只服务本模块多个路由；应用级跨模块状态才进入 core/service/。
  • 单页私有 Widget 优先作为 View 私有方法或相邻文件，不提前提升到模块 widgets/。
  • 修改现有页面时保留公开行为和路由契约，除非任务明确要求变更。

验证

格式化本次涉及的 Dart 文件，运行最小相关测试、必要的 Preview 测试、flutter analyze 相关范围和 git diff --check。确认没有手工修改生成文件。

What ships with it

1 file 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.

Changes

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.
