Implementation Reference

• claude-code-server/src/index.ts:383-394 (registration)

  Registration of the 'simulate_command' tool in the ListTools handler, defining its name, description, and input schema.

  {
    name: 'simulate_command',
    description: 'Simulates the execution of a given command.',
    inputSchema: {
      type: 'object',
      properties: {
        command: { type: 'string', description: 'Command to execute' },
        input: { type: 'string', description: 'Input data', default: '' }
      },
      required: ['command']
    }
  },

• claude-code-server/src/index.ts:386-393 (schema)

  Input schema for the simulate_command tool: object with required 'command' string and optional 'input' string.

  inputSchema: {
    type: 'object',
    properties: {
      command: { type: 'string', description: 'Command to execute' },
      input: { type: 'string', description: 'Input data', default: '' }
    },
    required: ['command']
  }

• claude-code-server/src/index.ts:583-591 (handler)

  Handler implementation for 'simulate_command': destructures command and input, builds a simulation prompt for Claude CLI via runClaudeCommand helper, returns the AI-generated simulation output as text content.

  case 'simulate_command': {
    const { command, input } = args;
    logger.debug(`Processing simulate_command request, command: ${command}`);
    const prompt = `You are super professional engineer. Simulate the execution of the following command:\n\nCommand: ${command}\n\nInput: ${input || 'No input provided.'}\n\nDescribe the expected behavior and output, without actually executing the command.`;
    logger.debug('Calling Claude CLI with prompt');
    const output = await runClaudeCommand(['--print'], prompt);
    logger.debug(`Received response from Claude, length: ${output.length}`);
    return { content: [{ type: 'text', text: output }] };
  }
