Implementation Reference

  • The core handler function that executes the file writing logic using fs.promises.writeFile, with error handling.
    async writeFile(filePath, content) {
      try {
        await fs.writeFile(filePath, content, 'utf-8');
        return { success: true, path: filePath, message: '文件写入成功' };
      } catch (error) {
        return { success: false, error: error.message };
      }
    }
  • The tool definition including name, description, and input schema (path and content required strings).
    {
      name: 'write_file',
      description: '写入文件内容',
      inputSchema: {
        type: 'object',
        properties: {
          path: { type: 'string', description: '文件路径' },
          content: { type: 'string', description: '文件内容' },
        },
        required: ['path', 'content'],
      },
    },
  • Dispatches write_file calls to the writeFile handler in the executeTool switch statement.
    case 'write_file':
      return await this.writeFile(args.path, args.content);
  • src/server.js:44-44 (registration)
    Instantiates the FileSystemTools class, which provides the write_file tool, and registers it in the server's tools map.
    filesystem: new FileSystemTools(),
  • Includes 'write_file' in the list of supported tools for the canHandle method.
    const tools = ['read_file', 'write_file', 'list_directory', 'create_directory', 
                   'delete_file', 'copy_file', 'move_file', 'search_files'];
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden for behavioral disclosure. The description only states the basic action ('write file content') without any information about permissions required, whether it overwrites existing files, what happens if the path doesn't exist, error conditions, or any side effects. This is critically inadequate for a file system mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

While technically concise with just four Chinese characters, this is an example of under-specification rather than effective conciseness. The description fails to provide necessary context and is too minimal to be helpful, earning a low score despite its brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a file system mutation tool with no annotations and no output schema, the description is completely inadequate. It doesn't explain what the tool returns, what errors might occur, file permission considerations, or any behavioral nuances. The description fails to compensate for the lack of structured metadata.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with both parameters ('path' and 'content') clearly documented in the schema. The description doesn't add any meaningful parameter semantics beyond what the schema already provides, so it meets the baseline of 3 for adequate coverage through schema alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description '写入文件内容' (write file content) is a tautology that essentially restates the tool name 'write_file' in Chinese. It specifies the verb 'write' and resource 'file content', but doesn't distinguish this tool from any potential siblings or provide any additional context about what makes this tool unique.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides absolutely no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, when-not-to-use scenarios, or comparison to sibling tools like 'copy_file', 'move_file', or 'read_file' that exist on the same server.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
