File Operations Skill

Read, write, and manage files on the local system.

Usage

{"thought": "...", "tool": "readFile|writeFile|appendFile|listDir", "args": {...}}

Examples

Read then Modify

User: "帮我看看 config.json 的内容，把端口改成 8080" Step 1:

{"thought": "先读取 config.json 查看当前内容", "tool": "readFile", "args": {"path": "config.json"}}

Step 2 (after reading, found port: 3000):

{"thought": "当前端口是 3000，需要改为 8080。将修改后的完整内容写回文件。", "tool": "writeFile", "args": {"path": "config.json", "content": "{\"port\": 8080, \"host\": \"localhost\"}"}}

Explore Directory

User: "帮我看看项目里有哪些 markdown 文件" Step 1:

{"thought": "先列出项目根目录，查找 .md 文件", "tool": "listDir", "args": {"path": "."}}

Step 2 (if found subdirectories):

{"thought": "根目录有 docs 文件夹，可能有更多 markdown 文件", "tool": "listDir", "args": {"path": "docs"}}

Append Log

User: "帮我在日志文件里记录一下今天完成了登录功能"

{"thought": "用 appendFile 追加记录到日志，不会覆盖已有内容", "tool": "appendFile", "args": {"path": "dev-log.md", "content": "\n- 2024-01-15: 完成登录功能开发\n"}}

Notes

• Use relative paths from project root
• readFile before writeFile to avoid accidental overwrites
• appendFile is safer than writeFile for logs and records
• writeFile will create parent directories if they don't exist
