-# [PROJECT_NAME] Constitution
-<!-- Example: Spec Constitution, TaskFlow Constitution, etc. -->
+<!--
+# Sync Impact Report
+**Version Change**: Template (unversioned) → 1.0.0
+**Bump Rationale**: Initial constitution creation with SOLID, KISS, YAGNI, DRY principles
+
+## Modified Principles
+- Template placeholders → Concrete SOLID, KISS, YAGNI, DRY principles
+- Generic governance → Specific CLI tool governance for atomctl
+
+## Added Sections
+- SOLID Principles (5 principles with detailed explanations)
+- KISS Principle (simplicity focus)
+- YAGNI Principle (avoiding over-engineering)
+- DRY Principle (eliminating duplication)
+- Code Quality Standards (testing, CLI consistency, error handling)
+- Performance Requirements (generation speed, UX consistency)
+- Development Workflow (code generation process, template management)
+- Governance (amendment process, versioning policy, compliance review)
+
+## Templates Updated
+- ✅ `.specify/templates/plan-template.md` - Updated Constitution Check section
+- ✅ `.specify/templates/tasks-template.md` - Updated Task Generation Rules
+- ✅ `.specify/templates/spec-template.md` - No changes needed (already principle-agnostic)
+- ✅ `.specify/templates/agent-file-template.md` - No changes needed (not found)
+
+## Follow-up TODOs
+- Review all generated code for compliance with new constitution
+- Update any existing command documentation to reference new principles
+- Consider adding principle-specific validation to CI/CD pipeline

 ## Core Principles
 
-### [PRINCIPLE_1_NAME]
-<!-- Example: I. Library-First -->
-[PRINCIPLE_1_DESCRIPTION]
-<!-- Example: Every feature starts as a standalone library; Libraries must be self-contained, independently testable, documented; Clear purpose required - no organizational-only libraries -->
+### I. SOLID Principles
+**Single Responsibility Principle**: 每个组件、类和函数必须有单一明确的职责。命令、生成器和工具应当各司其职，避免功能混杂。
 
-### [PRINCIPLE_2_NAME]
-<!-- Example: II. CLI Interface -->
-[PRINCIPLE_2_DESCRIPTION]
-<!-- Example: Every library exposes functionality via CLI; Text in/out protocol: stdin/args → stdout, errors → stderr; Support JSON + human-readable formats -->
+**Open/Closed Principle**: 软件实体应该对扩展开放，对修改关闭。通过插件化的模板系统和可配置的生成器来实现扩展性，而不是修改核心代码。
 
-### [PRINCIPLE_3_NAME]
-<!-- Example: III. Test-First (NON-NEGOTIABLE) -->
-[PRINCIPLE_3_DESCRIPTION]
-<!-- Example: TDD mandatory: Tests written → User approved → Tests fail → Then implement; Red-Green-Refactor cycle strictly enforced -->
+**Liskov Substitution Principle**: 子类型必须能够无缝替换其基类型。所有生成器接口和命令处理器都应遵循一致的契约。
 
-### [PRINCIPLE_4_NAME]
-<!-- Example: IV. Integration Testing -->
-[PRINCIPLE_4_DESCRIPTION]
-<!-- Example: Focus areas requiring integration tests: New library contract tests, Contract changes, Inter-service communication, Shared schemas -->
+**Interface Segregation Principle**: 接口应该特定且专注，避免"胖接口"。为不同类型的生成操作定义专门的接口。
 
-### [PRINCIPLE_5_NAME]
-<!-- Example: V. Observability, VI. Versioning & Breaking Changes, VII. Simplicity -->
-[PRINCIPLE_5_DESCRIPTION]
-<!-- Example: Text I/O ensures debuggability; Structured logging required; Or: MAJOR.MINOR.BUILD format; Or: Start simple, YAGNI principles -->
+**Dependency Inversion Principle**: 依赖抽象而非具体实现。核心功能应依赖接口，而不是特定的模板引擎或数据库驱动。
 
-## [SECTION_2_NAME]
-<!-- Example: Additional Constraints, Security Requirements, Performance Standards, etc. -->
+### II. KISS (Keep It Simple, Stupid)
+追求终极的简洁性和直观性，避免不必要的复杂性。命令行接口必须保持一致性，参数命名和输出格式应当直观易懂。代码生成逻辑应当简单直接，避免过度工程化。
 
-[SECTION_2_CONTENT]
-<!-- Example: Technology stack requirements, compliance standards, deployment policies, etc. -->
+### III. YAGNI (You Aren't Gonna Need It)
+只实现当前明确需要的功能，避免过度设计和为未来功能预留。每个新功能都必须有明确的用户需求支撑，避免基于猜测的"可能有用"的功能。
 
-## [SECTION_3_NAME]
-<!-- Example: Development Workflow, Review Process, Quality Gates, etc. -->
+### IV. DRY (Don't Repeat Yourself)
+识别并消除代码或逻辑中的重复模式，提高可重用性。模板系统、代码生成器和公共工具函数应当避免重复实现相同功能。
 
-[SECTION_3_CONTENT]
-<!-- Example: Code review requirements, testing gates, deployment approval process, etc. -->
+## Code Quality Standards
+
+### Testing Discipline
+- **TDD Mandatory**: 测试驱动开发必须严格执行，先写测试 → 用户确认 → 测试失败 → 然后实现
+- **Red-Green-Refactor**: 严格遵守红-绿-重构循环
+- **Integration Testing**: 需要集成测试的重点领域：新生成器合同测试、合同变更、服务间通信、共享模式
+
+### CLI Interface Consistency
+- **统一参数格式**: 所有命令遵循相同的参数命名约定（`--force`, `--dry-run`, `--dir`）
+- **标准输出格式**: 支持 JSON 和人类可读格式，错误信息输出到 stderr
+- **文本 I/O 协议**: stdin/args → stdout，错误 → stderr
+
+### Error Handling Completeness
+- **完整的错误信息**: 提供清晰的错误描述和建议解决方案
+- **错误恢复机制**: 在可能的情况下提供恢复选项
+- **错误日志记录**: 结构化日志记录，便于调试和监控
+
+## Performance Requirements
+
+### Generation Performance
+- **代码生成速度**: 大型项目的代码生成必须在合理时间内完成（< 5秒）
+- **内存使用**: 避免在生成过程中出现不必要的内存峰值
+- **并行处理**: 在可能的情况下支持并行生成独立组件
+
+### User Experience Consistency
+- **响应性**: 所有命令操作必须提供即时反馈
+- **进度指示**: 长时间运行的操作必须显示进度
+- **一致性**: 所有命令的行为和输出格式保持一致
+
+## Development Workflow
+
+### Code Generation Process
+1. **分析阶段**: 扫描项目结构，理解现有代码模式
+2. **生成阶段**: 基于模板和配置生成代码
+3. **验证阶段**: 确保生成代码的正确性和一致性
+4. **格式化阶段**: 自动应用代码格式化标准
+
+### Template Management
+- **模板版本控制**: 所有模板必须版本化，确保可重现性
+- **模板测试**: 每个模板必须有对应的测试用例
+- **模板文档**: 复杂模板必须有详细的使用说明
 
 ## Governance
-<!-- Example: Constitution supersedes all other practices; Amendments require documentation, approval, migration plan -->
 
-[GOVERNANCE_RULES]
-<!-- Example: All PRs/reviews must verify compliance; Complexity must be justified; Use [GUIDANCE_FILE] for runtime development guidance -->
+### Constitution Supremacy
+本章程优先于所有其他实践规范。所有代码审查和 PR 都必须验证合规性。
 
-**Version**: [CONSTITUTION_VERSION] | **Ratified**: [RATIFICATION_DATE] | **Last Amended**: [LAST_AMENDED_DATE]
-<!-- Example: Version: 2.1.1 | Ratified: 2025-06-13 | Last Amended: 2025-07-16 -->

+### Amendment Process
+- **修改提案**: 任何章程修改必须有明确的提案和理由
+- **审查批准**: 修改需要经过核心团队审查和批准
+- **迁移计划**: 重大变更必须有详细的迁移计划
+- **文档更新**: 修改必须同步更新所有相关文档
+
+### Versioning Policy
+- **MAJOR**: 向后不兼容的治理原则删除或重新定义
+- **MINOR**: 新原则或部分添加或实质性扩展指导
+- **PATCH**: 澄清、措辞、拼写修正、非语义优化
+
+### Compliance Review
+- **定期审查**: 每季度审查章程的执行情况
+- **违规处理**: 对违反章程的行为必须有明确的处理流程
+- **持续改进**: 基于实际使用经验持续优化章程内容
