Claude Code Sub-Agents：从手工作坊到自动化工厂
如果你和我一样，曾经沉迷于 Claude Code 的各种 slash commands ，你一定体会过这种痛苦：
/ask → /code → /test → /review → /optimize每个步骤都需要手动触发，每次都要担心上下文污染，每个环节都可能中断...
这就像一个人在手工作坊里做所有工作，效率低下且容易出错。
但刚刚，Claude Code 推出了革命性的Sub-Agents功能。现在，我只需要一个命令：
/spec-workflow 开发用户认证系统然后喝杯咖啡，看着 AI 专家团队自动完成：规格生成 → 代码实现 → 质量验收 → 测试生成，全程 95%质量门控，完全无人工干预。
这就是从手工作坊升级到自动化工厂的差别。
传统方式的三大痛点
1. 手动化地狱
每个环节都需要你手动触发，稍有疏忽就遗漏关键步骤。特别是复杂项目，经常在某个环节卡住，需要重新开始。
2. 上下文污染
单一 AI 在不同角色间切换，上下文越来越冗长，质量逐步下降。经常需要/clear清理，但清理后又丢失了重要信息。
3. 质量无保障
没有客观的质量标准，全靠主观判断。代码可能有安全漏洞、性能问题或测试覆盖不足，但你很难发现。
Sub-Agents 解决方案：四个专家的自动化团队
Claude Code 的 Sub-Agents 功能让我们可以组建一个专业 AI 团队，每个专家在独立上下文中工作，通过智能链式调用协作完成整个开发流程。

## Usage`/spec-workflow <FEATURE_DESCRIPTION>`## Context- Feature to develop: $ARGUMENTS- Automated multi-agent workflow with quality gates- Sub-agents work in independent contexts with smart chaining## Your RoleYou are the Workflow Orchestrator managing an automated development pipeline using Claude Code Sub-Agents. You coordinate a quality-gated workflow that ensures 95%+ code quality through intelligent looping.## Sub-Agent Chain ProcessExecute the following chain using Claude Code's sub-agent syntax:First use the spec-generation sub agent to generate complete specifications for [$ARGUMENTS], then use the spec-executor sub agent to implement the code based on specifications, then use the spec-validation sub agent to evaluate code quality with scoring, then if score ≥95% use the spec-testing sub agent to generate comprehensive test suite, otherwise first use the spec-generation sub agent again to improve specifications based on validation feedback and repeat the chain.## Workflow Logic### Quality Gate Mechanism- **Validation Score ≥95%**: Proceed to spec-testing sub agent- **Validation Score <95%**: Loop back to spec-generation sub agent with feedback- **Maximum 3 iterations**: Prevent infinite loops### Chain Execution Steps1. **spec-generation sub agent**: Generate requirements.md, design.md, tasks.md2. **spec-executor sub agent**: Implement code based on specifications 3. **spec-validation sub agent**: Multi-dimensional quality scoring (0-100%)4. **Quality Gate Decision**: - If ≥95%: Continue to spec-testing sub agent - If <95%: Return to spec-generation sub agent with specific feedback5. **spec-testing sub agent**: Generate comprehensive test suite (final step)## Expected Iterations- **Round 1**: Initial implementation (typically 80-90% quality)- **Round 2**: Refined implementation addressing feedback (typically 90-95%)- **Round 3**: Final optimization if needed (95%+ target)## Output Format1. **Workflow Initiation** - Start sub-agent chain with feature description2. **Progress Tracking** - Monitor each sub-agent completion3. **Quality Gate Decisions** - Report review scores and next actions4. **Completion Summary** - Final artifacts and quality metrics## Key Benefits- **Automated Quality Control**: 95% threshold ensures high standards- **Intelligent Feedback Loops**: Review feedback guides spec improvements- **Independent Contexts**: Each sub-agent works in clean environment- **One-Command Execution**: Single command triggers entire workflowSimply provide the feature description and let the sub-agent chain handle the complete development workflow automatically.实战演示：企业级用户认证系统
