Component: [Module/Service/Feature affected]

Description:
- Current behavior (what's wrong)
- Expected behavior (what should happen)
- Root cause analysis

Impact Assessment:
- User impact (UX degradation, data loss, security exposure)
- System impact (performance, stability, scalability)
- Business impact (compliance, revenue, reputation)

Reproduction Steps:
1. [Step-by-step instructions]

2. 先编写失败的测试（TDD 方法）
3. 实施最小化、聚焦的修复
4. 验证测试通过
5. 运行回归测试
6. 如有需要，更新文档

4.2 修复指南

• 最小变更原则：做出能正确修复问题的最小变更
• 禁止范围蔓延：避免无关的重构或改进
• 保持向后兼容性：除非缺陷本身就是破坏性 API
• 遵循项目标准：使用现有的代码风格和模式
• 添加防御性编程：防止未来出现类似缺陷

4.3 代码审查清单

• 修复针对根本原因，而不仅仅是症状
• 所有边界情况均已处理
• 错误信息清晰且可操作
• 性能影响可接受
• 已考虑安全影响
• 未引入新的警告或 lint 错误

阶段 5：测试与验证

5.1 测试要求

对于每个已修复的缺陷，提供：

1. 单元测试：针对特定修复的隔离测试
2. 集成测试：如果缺陷涉及多个组件
3. 回归测试：确保修复不会破坏现有功能
4. 边界情况测试：覆盖相关的边界条件

5.2 测试结构

describe('BUG-[ID]: [Bug description]', () => {
  test('should fail with original bug', () => {
    // This test would fail before the fix
    // Demonstrates the bug
  });
  
  test('should pass after fix', () => {
    // This test passes after the fix
    // Verifies correct behavior
  });
  
  test('should handle edge cases', () => {
    // Additional edge case coverage
  });
});

5.3 验证步骤

1. 运行完整测试套件：[npm test | pytest | go test ./... | mvn test | 等]
2. 检查代码覆盖率变化
3. 运行静态分析工具
4. 验证性能基准（如适用）
5. 在不同环境中测试（如可能）

阶段 6：文档与报告

Objective

Conduct a thorough analysis of the entire repository to identify, prioritize, fix, and document ALL verifiable bugs, security vulnerabilities, and critical issues across any programming language, framework, or technology stack.

Phase 1: Initial Repository Assessment

1.1 Architecture Mapping

• Map complete project structure (src/, lib/, tests/, docs/, config/, scripts/, etc.)
• Identify technology stack and dependencies (package.json, requirements.txt, go.mod, pom.xml, Gemfile, etc.)
• Document main entry points, critical paths, and system boundaries
• Analyze build configurations and CI/CD pipelines
• Review existing documentation (README, API docs, architecture diagrams)

1.2 Development Environment Analysis

• Identify testing frameworks (Jest, pytest, PHPUnit, Go test, JUnit, RSpec, etc.)
• Review linting/formatting configurations (ESLint, Prettier, Black, RuboCop, etc.)
• Check for existing issue tracking (GitHub Issues, TODO/FIXME/HACK/XXX comments)
• Analyze commit history for recent problematic areas
• Review existing test coverage reports if available

Phase 2: Systematic Bug Discovery

2.1 Bug Categories to Identify

Critical Bugs:

• Security vulnerabilities (SQL injection, XSS, CSRF, auth bypass, etc.)
• Data corruption or loss risks
• System crashes or deadlocks

Phase 3: Bug Documentation & Prioritization

3.1 Bug Report Template

For each identified bug, document:

BUG-ID: [Sequential identifier]
Severity: [CRITICAL | HIGH | MEDIUM | LOW]
Category: [Security | Functional | Performance | Integration | Code Quality]
File(s): [Complete file path(s) and line numbers]
Component: [Module/Service/Feature affected]

Description:
- Current behavior (what's wrong)
- Expected behavior (what should happen)
- Root cause analysis

Impact Assessment:
- User impact (UX degradation, data loss, security exposure)
- System impact (performance, stability, scalability)
- Business impact (compliance, revenue, reputation)

Reproduction Steps:
1. [Step-by-step instructions]
2. [Include test data/conditions if needed]
3. [Expected vs actual results]

Verification Method:
- [Code snippet or test that demonstrates the bug]
- [Metrics or logs showing the issue]

Dependencies:
- Related bugs: [List of related BUG-IDs]
- Blocking issues: [What needs to be fixed first]

3.2 Prioritization Matrix

Rank bugs using:

• Severity: Critical > High > Medium > Low
• User Impact: Number of affected users/features
• Fix Complexity: Simple < Medium < Complex
• Risk of Regression: Low < Medium < High

Phase 4: Fix Implementation

4.1 Fix Strategy

For each bug:

1. Create isolated fix branch (if using version control)
2. Write failing test FIRST (TDD approach)
3. Implement minimal, focused fix
4. Verify test passes
5. Run regression tests
6. Update documentation if needed

4.2 Fix Guidelines

• Minimal Change Principle: Make the smallest change that correctly fixes the issue
• No Scope Creep: Avoid unrelated refactoring or improvements
• Preserve Backwards Compatibility: Unless the bug itself is a breaking API
• Follow Project Standards: Use existing code style and patterns
• Add Defensive Programming: Prevent similar bugs in the future

4.3 Code Review Checklist

• Fix addresses the root cause, not just symptoms
• All edge cases are handled
• Error messages are clear and actionable
• Performance impact is acceptable
• Security implications considered
• No new warnings or linting errors introduced

Phase 5: Testing & Validation

5.1 Test Requirements

For EVERY fixed bug, provide:

1. Unit Test: Isolated test for the specific fix
2. Integration Test: If bug involves multiple components
3. Regression Test: Ensure fix doesn't break existing functionality
4. Edge Case Tests: Cover related boundary conditions

5.2 Test Structure

describe('BUG-[ID]: [Bug description]', () => {
  test('should fail with original bug', () => {
    // This test would fail before the fix
    // Demonstrates the bug
  });
  
  test('should pass after fix', () => {
    // This test passes after the fix
    // Verifies correct behavior
  });
  
  test('should handle edge cases', () => {
    // Additional edge case coverage
  });
});

5.3 Validation Steps

1. Run full test suite: [npm test | pytest | go test ./... | mvn test | etc.]
2. Check code coverage changes
3. Run static analysis tools
4. Verify performance benchmarks (if applicable)
5. Test in different environments (if possible)

Phase 6: Documentation & Reporting

6.1 Fix Documentation

For each fixed bug:

• Update inline code comments explaining the fix
• Add/update API documentation if behavior changed
• Create/update troubleshooting guides
• Document any workarounds for unfixed issues

Special Considerations

• For monorepos: Analyze each package separately
• For microservices: Consider inter-service dependencies
• For legacy code: Balance fix risk vs benefit
• For third-party dependencies: Report upstream if needed
