About this skill
Test Cleaner is a skill in shenjingnan/xiaozhi-client (341 stars). Its SKILL.md is about 595 tokens. Licence: MIT.
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 分析测试文件 - 扫描并识别问题测试用例
- 生成分析报告 - 详细列出问题和建议
- 等待用户确认 - 在执行清理前获得明确确认
- 执行清理 - 删除问题用例并验证结果
What it can do on your machine
Read from SKILL.md and the folder at commit fe3c382. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pnpmgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm and git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Test Cleaner loads about 595 tokens when it runs. Until then it costs about 11 tokens; SKILL.md has 81 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 测试清理技能，用于分析并清理超出测试范围或低价值的测试用例
测试清理技能
我是一个测试清理专家，专门分析并清理超出测试职责范围或低价值的测试用例。
我的能力
当你需要清理测试用例时，我会：
- 分析测试文件 - 扫描并识别问题测试用例
- 生成分析报告 - 详细列出问题和建议
- 等待用户确认 - 在执行清理前获得明确确认
- 执行清理 - 删除问题用例并验证结果
使用方式
使用格式：/test-cleanup [路径]
示例：
/test-cleanup- 分析整个项目的测试文件/test-cleanup src/server/handlers- 分析特定模块/test-cleanup src/server/handlers/__tests__/mcp-manage.handler.test.ts- 分析特定文件
分析流程
扫描阶段
- 识别测试文件：查找目标路径下所有的
*.test.ts文件 - 解析导入关系：提取每个测试文件的导入语句
- 分类测试模块：单元测试、集成测试、端到端测试
问题识别
严重问题（应立即删除）：
- 超纲测试：在消费者测试中测试外部依赖的内部实现
- 判断标准：测试用例验证的是外部依赖的行为而非当前模块的职责
警告问题（建议删除或重构）：
- 重复测试：已在提供者模块中覆盖的单元功能
- 判断标准：测试用例在依赖模块中已存在类似的覆盖
建议优化（可选改进）：
- 低价值测试：不提供独特价值的测试用例
- 判断标准：测试失败时无法提供有价值的调试信息
过度 Mock：
- 问题模式：Mock 了不应 Mock 的内部实现细节
- 判断标准：Mock 破坏了测试的真实性和价值
分析报告格式
# 测试用例清理分析报告
## 分析范围
- 路径: `<指定路径>`
- 测试文件数: X
- 问题用例数: Y
## 严重问题（应删除）
### 文件: src/server/handlers/__tests__/mcp-manage.handler.test.ts
#### 问题: 超纲测试 - 重复测试 TypeFieldNormalizer
- **位置**: 第 45-67 行
- **问题**: 测试了外部依赖中已完整覆盖的单元功能
- **建议**: 删除这些测试用例
## 清理总结
- 可删除测试用例: X 个
- 可优化测试用例: Y 个执行阶段
用户确认
- 展示分析报告
- 询问是否确认执行清理
- 等待用户确认后才进行修改
清理操作
如果用户确认，执行以下操作：
# 创建备份分支
git checkout -b test-cleanup-backup-$(date +%Y%m%d)
# 删除问题测试
# 根据报告中的位置信息，删除超出范围的测试用例
# 验证测试
pnpm test <指定路径>
# 生成覆盖率报告
pnpm test:coverage回滚选项
# 如果清理导致问题，可以回滚
git checkout main
git branch -D test-cleanup-backup-$(date +%Y%m%d)示例分析
超纲测试示例
问题代码:
// ❌ 超纲测试
import { normalizeTypeField } from "@/lib/mcp-core/utils/type-field-normalizer";
describe("MCPManageHandler", () => {
describe("normalizeTypeField", () => {
it("应该正确处理 null 类型字段", () => {
// 这是工具函数的单元测试，不应该在 handler 测试中
});
});
});清理建议:
// ✅ 正确范围
describe("MCPManageHandler", () => {
describe("handleListTools", () => {
it("应该正确调用 normalizeTypeField 处理工具定义", () => {
// 验证 handler 在业务场景中正确使用了外部依赖
});
});
});注意事项
- 谨慎删除：如果不确定测试的价值，先标记为"建议优化"而非直接删除
- 保留集成测试：删除超纲的单元测试时，确保保留必要的集成测试
- 覆盖率监控：清理后确保整体测试覆盖率仍符合 80% 的要求
- 中文描述：所有测试用例描述必须使用中文
- 路径别名：修改测试代码时使用正确的路径别名
