工具组件指南
Skill 概述
本 Skill 涵盖了 BK-CI 中常用的 4 类工具组件,这些是特定功能的工具类和组件实现。
核心主题
| 主题 | 说明 | 文档 |
|---|---|---|
| JWT 安全认证 | JWT 生成验证、Token 刷新、OAuth2 | 1-jwt-security.md |
| 表达式解析器 | 变量表达式、条件求值、自定义函数 | 2-expression-parser.md |
| 线程池循环工具 | 线程池配置、批量处理、循环工具类 | 3-thread-pool-loop-util.md |
| 责任链模式 | 责任链设计、拦截器链、请求处理链 | 4-chain-responsibility.md |
⚠️ 与 common-technical-practices 的区别
定位对比
| Skill | 定位 | 关注点 | 典型场景 |
|---|---|---|---|
| common-technical-practices | 框架级实践 | 如何在 Spring Boot 中使用技术 | AOP 切面、分布式锁、重试机制、参数校验、性能监控、定时任务、审计日志 |
| utility-components (本 Skill) | 工具级组件 | 如何使用特定的工具类和组件 | JWT 认证、表达式解析、线程池使用、责任链实现 |
使用选择
需要实现横切关注点(AOP、锁、重试、监控)
→ 使用 common-technical-practices
需要使用特定工具类(JWT、表达式、线程池、责任链)
→ 使用 utility-components (本 Skill)
示例对比:
- 需要 添加性能监控切面 →
common-technical-practices(reference/5-performance-monitoring.md) - 需要 使用线程池批量处理 →
utility-components(reference/3-thread-pool-loop-util.md) - 需要 实现分布式锁 →
common-technical-practices(reference/2-distributed-lock.md) - 需要 实现 JWT 认证 →

一、JWT 安全认证
详见 reference/1-jwt-security.md
核心功能
- JWT Token 生成与验证
- Token 刷新机制
- 权限校验拦截器
- OAuth2 集成
快速开始
// 生成 JWT Token
val token = JwtManager.generateToken(userId, expireTime)
// 验证 Token
val claims = JwtManager.verifyToken(token)
二、表达式解析器
详见 reference/2-expression-parser.md
核心功能
- 变量表达式解析 (
${variable}) - 条件表达式求值
- 自定义函数扩展
- 表达式缓存优化
快速开始
// 解析变量表达式
val context = mapOf("buildId" to "b-123", "status" to "success")
val result = ExpressionParser.parse("${buildId}_${status}", context)
// 结果: "b-123_success"
三、线程池与循环工具
详见 reference/3-thread-pool-loop-util.md
核心功能
- 线程池配置与管理
- 批量任务并发处理
- 循环工具类 (
LoopUtil) - 并发控制与优化
快速开始
// 批量并发处理
val results = ThreadPoolUtil.executeBatch(taskList) { task ->
processTask(task)
}
// 循环重试
LoopUtil.loopWithRetry(maxRetries = 3) {
callExternalApi()
}
四、责任链模式
详见 reference/4-chain-responsibility.md
核心功能
- 责任链设计与实现
- 拦截器链模式
- 流水线插件链
- 请求处理链
快速开始
// 定义拦截器链
val chain = InterceptorChain()
.addInterceptor(AuthInterceptor())
.addInterceptor(ValidationInterceptor())
.addInterceptor(LoggingInterceptor())
// 执行链
chain.proceed(request)

This skill should be used when working on Godot Engine projects. It provides specialized knowledge of Godot's file formats (.gd, .tscn, .tres), architecture patterns (component-based, signal-driven, resource-based), common pitfalls, validation tools, code templates, and CLI workflows. The `godot` command is available for running the game, validating scripts, importing resources, and exporting builds. Use this skill for tasks involving Godot game development, debugging scene/resource files, implementing game systems, or creating new Godot components.
nano-banana-pro
garg-aayush
Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
