FlutterKit: Skill for Codex

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

fkit-native is a skill for Codex from Joker-x-dev/FlutterKit. It costs 70 tokens per session (550 once invoked), scanned A, original, MIT.

A Flutter development helper for managing app resources, icons, launch screens, platform settings, and release builds across Android, iOS, web, and desktop.

In plain words
What is it for?
Use it to create app icons and launch screens, generate typed resource accessors, synchronize native platform settings, diagnose display-cache issues, and build Flutter apps for multiple platforms.
Why use it?
It keeps source images and configuration in the right places and regenerates platform files consistently, reducing errors from editing generated files or debugging stale caches.

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-native 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 Native

必读资料

先阅读 AGENTS.md、docs/flutter-kit/扩展/assets.md、根目录 README.md 的构建章节，以及当前任务对应的 YAML 和原生平台文件。涉及生成器行为时查阅当前依赖版本的官方文档，不凭记忆填写配置。

资源边界

  • assets/image/、assets/icon/、assets/json/ 是运行时资源，由 FlutterGen 生成类型安全访问器。
  • assets/dev/ 只保存图标和启动页生成源图，不注册为运行时资源。
  • flutter_launcher_icons.yaml 管理多端桌面图标。
  • flutter_native_splash.yaml 管理 Android、iOS 与 Web 原生启动页。

工作流

  1. 明确目标平台和目标效果，检查源图尺寸、画布、Alpha、透明边距及安全区。
  2. 修改源图或 YAML，不直接编辑将被生成器覆盖的输出文件。
  3. 只运行任务需要的生成命令，并审查各平台生成差异。
  4. Android 12 启动图遵守中心安全区；iOS 图标使用独立安全边距源图并移除 Alpha。
  5. 区分原生 LaunchScreen 与 Flutter 首帧，避免 Dart 页面重复展示第二个启动 Logo。
  6. 原生效果未更新时先诊断 App、Simulator/Xcode/Gradle 缓存，不反复改变正确配置。
  7. 按目标平台运行构建或最小启动验证，保留混淆符号文件和发布配置。

常用命令

  • 资源代码：dart run build_runner build --delete-conflicting-outputs
  • 图标：dart run flutter_launcher_icons
  • 启动页：dart run flutter_native_splash:create
  • 质量检查：flutter analyze、flutter test、git diff --check

验证

检查配置解析、源图尺寸、生成文件、Git 差异和目标平台实际显示。生成器产生无关格式变化时单独识别，不覆盖用户的原生工程修改。

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.
