🔗 Skill Chain v1.0

声明式技能编排，实现复杂自动化流程

核心概念

Chain = 技能的有序组合 + 条件逻辑 + 错误处理

声明式配置示例

# .claude/skills/skill-chain/chains/on-commit.yaml
chain:
  name: on-commit
  description: "Git commit 时的完整检查流程"

  steps:
    - name: lint
      skill: commit-validator
      config:
        mode: quick

    - name: test
      skill: test-runner
      config:
        mode: quick

    - name: self-heal
      skill: self-healing-executor
      if: "test.failed"
      config:
        max_attempts: 3

    - name: record
      skill: learning-recorder
      if: "self-heal.success"
      config:
        type: best-practice

预定义链条

链条	触发	说明
on-commit	git commit	lint → test → self-heal → record
on-change	文件变更	检测 → 触发对应技能
on-deploy	部署前	dependency → env → security → test → deploy
hourly-check	cron	health → self-heal → notify

使用方式

CLI

# 运行预定义链条
python3 .claude/skills/skill-chain/scripts/run.py on-commit
python3 .claude/skills/skill-chain/scripts/run.py on-change --files server.py
python3 .claude/skills/skill-chain/scripts/run.py on-deploy

# 运行自定义链条
python3 .claude/skills/skill-chain/scripts/run.py --config /path/to/chain.yaml

# 列出所有链条
python3 .claude/skills/skill-chain/scripts/run.py list

Python API

from skill_chain import ChainRunner

runner = ChainRunner()
result = runner.run("on-commit")

if result.success:
    print("Chain completed successfully")
else:
    print(f"Chain failed at step: {result.failed_step}")

输出示例

🔗 Running chain: on-commit
==================================================

Step 1/4: lint
🚀 commit-validator
├── ❌ Lint: FAIL (3 errors)

Step 1 failed, checking conditions...
Condition: lint.failed = true → skip to self-heal
Step 2/4: self-heal
🚀 self-healing-executor
├── ✅ Fixed in 2.1s
Step 3/4: record
🚀 learning-recorder
├── 📝 Learning recorded

Step 4/4: test (retry)
🚀 test-runner
├── ✅ PASS (1071 tests)

==================================================
✅ Chain completed (3/4 steps executed)
Duration: 125s

条件表达式

表达式	说明	示例
step.failed	上一步失败	if: "lint.failed"
step.success	上一步成功	if: "test.success"
result.code == 0	返回码判断	if: "result.code == 0"
output contains "error"	输出匹配	if: "output contains 'error'"

错误处理

chain:
  name: robust-chain
  on_error: continue  # 继续执行还是中断

  steps:
    - name: risky-step
      skill: deployment-checker
      on_error: continue  # 失败后继续

    - name: cleanup
      skill: learning-recorder
      on_error: halt      # 失败后停止

状态码

状态码	含义
0	链条执行成功
1	链条执行失败
2	配置错误
3	超时
