FlutterKit: Skill for Codex

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

fkit-data is a skill for Codex from Joker-x-dev/FlutterKit. It costs 64 tokens per session (563 once invoked), scanned A, original, MIT.

A Flutter development helper for connecting app features to data sources. It covers models, network requests and responses, repositories, databases, local key-value storage, shared services, and paginated lists.

In plain words
What is it for?
Use it to add API integrations, create data models, persist data, build network lists, handle results and pagination, and generate code from Flutter annotations.
Why use it?
It provides consistent paths for loading, storing, and presenting data, reducing duplicated request handling and preventing feature code from depending directly on low-level storage details.

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-data 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.

What it actually says

FKit Data

必读资料

先阅读 AGENTS.md，再根据数据来源读取：

  • 总体边界：docs/flutter-kit/框架核心/data.md
  • 模型：docs/flutter-kit/框架核心/model.md
  • 网络：docs/flutter-kit/框架核心/network.md、docs/flutter-kit/框架核心/result.md
  • 数据库：docs/flutter-kit/框架核心/database.md
  • 键值存储：docs/flutter-kit/框架核心/datastore.md
  • 全局状态：docs/flutter-kit/框架核心/state.md
  • 页面状态机：对应 docs/flutter-kit/框架核心/base-network.md、docs/flutter-kit/框架核心/base-list.md 或 docs/flutter-kit/框架核心/base-refresh.md

选择数据链路

  • 网络：Model → Network DataSource → Repository → RequestHelper 或网络父类 → Logic/State。
  • SQLite：Database Entity/Provider → Local DataSource → Repository → Logic/Service。
  • 键值存储：Store DataSource → Store Repository → Logic/Service。
  • 长期状态：Repository 恢复持久化数据 → Core Service 维护跨模块状态。

Feature 只能依赖 Repository 或 Service，不直接依赖具体 DataSource 实现。

工作流

  1. 从真实契约确定 Entity、Request、Response、可空性、成功码和分页字段。
  2. 复用现有基础模型和数据源结构，保持接口、实现和 Repository 单一职责。
  3. 使用完整领域名声明 Repository 字段，不使用 _repository。
  4. 网络结果交给 RequestHelper 或网络父类统一处理；不要在 Logic 重复制造复杂 try/catch、Toast 和 loading 生命周期。
  5. 页面展示状态写入 Feature State；持久化状态通过 Repository/DataSource；跨模块长期状态才进入 Core Service。
  6. 修改注解或 Retrofit 声明后运行代码生成，不手工修改 *.g.dart。

验证

为 DataSource、Repository、Result 或 Service 补充成功、业务失败、异常、空值和分页边界测试。运行代码生成、相关测试、静态分析和 git diff --check，确认 Feature 未绕过 Repository。

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.
