Coding Agent — 自主编程与代码开发

通过 Executor 的 ReAct 循环和 python_interpreter 工具，自主完成代码编写、调试和项目管理任务。

适用场景

• 按需求编写新功能代码（Python、JavaScript、Shell 等）
• 修复 Bug：读取错误信息 → 定位代码 → 修改验证
• 代码重构：优化结构、提升可读性
• 创建新项目脚手架（目录结构、配置文件、入口文件）
• 编写和运行单元测试
• 依赖管理：安装、升级、解决冲突

编码工作流

import subprocess

# 1. 读取目标文件
with open("src/module.py", "r", encoding="utf-8") as f:
    original = f.read()

# 2. 应用修改
modified = original.replace("old_code", "new_code")

# 3. 写回文件
with open("src/module.py", "w", encoding="utf-8") as f:
    f.write(modified)

# 4. 运行测试验证
result = subprocess.run(
    ["python", "-m", "pytest", "tests/", "-x"],
    capture_output=True, text=True, encoding="utf-8"
)
print(result.stdout)
if result.returncode != 0:
    print("TESTS FAILED:", result.stderr)

创建新项目模板

import os

project_name = "my_project"
base = os.path.join(os.getcwd(), project_name)

structure = {
    "src/__init__.py": "",
    "src/main.py": 'def main():\n    print("Hello")\n\nif __name__ == "__main__":\n    main()\n',
    "tests/__init__.py": "",
    "tests/test_main.py": "from src.main import main\ndef test_main():\n    main()\n",
    "pyproject.toml": '[project]\nname = "' + project_name + '"\nversion = "0.1.0"\n',
    "README.md": "# " + project_name + "\n",
}

for path, content in structure.items():
    full = os.path.join(base, path)
    os.makedirs(os.path.dirname(full), exist_ok=True)
    with open(full, "w", encoding="utf-8") as f:
        f.write(content)

注意事项

1. 编码一致性：始终使用 encoding="utf-8" 避免中文乱码
2. 原子写入：先写临时文件再 rename，防止写入中断导致文件损坏
3. 测试先行：修改代码后立即运行相关测试
4. 依赖检查：安装新包后确认 pyproject.toml 同步更新
5. 路径安全：不在用户未授权的目录外创建或删除文件
