Implementation Reference

• src/index.ts:440-447 (handler)

  Handler for the 'review.version' tool: runs 'review --version' via withBundle helper and returns the version string as JSON.

  case "review.version": {
    const { stdout } = await withBundle(args.cwd as string, ["review", "--version"]);
    return { 
      content: [
        { type: "text", text: JSON.stringify({ version: stdout.trim() }) }
      ]
    };
  }

• src/index.ts:256-260 (schema)

  Input schema for 'review.version' tool requiring 'cwd' parameter.

  inputSchema: { 
    type: "object", 
    properties: { cwd: { type: "string" } }, 
    required: ["cwd"] 
  }

• src/index.ts:253-261 (registration)

  Tool definition object for 'review.version' included in the tools array returned by listTools.

  {
    name: "review.version",
    description: "Return Re:VIEW CLI version (prefers bundle exec).",
    inputSchema: { 
      type: "object", 
      properties: { cwd: { type: "string" } }, 
      required: ["cwd"] 
    }
  },

• src/index.ts:425-429 (registration)

  ListTools request handler registration that exposes the tools list including 'review.version'.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return {
      tools: tools
    };
  });

• src/index.ts:51-61 (helper)

  Helper function 'withBundle' used by the 'review.version' handler to prefer bundled 'review' command execution.

  async function withBundle(cwd: string, argv: string[]) {
    try {
      // If Bundler works, prefer bundle exec to respect project Gemfile
      await execp("bundle", ["exec", "ruby", "-v"], { cwd, timeout: 8000 });
      return await execp("bundle", ["exec", ...argv], { cwd, timeout: 60000, maxBuffer: 10*1024*1024 });
    } catch {
      // Fallback to direct command
      const [cmd, ...rest] = argv;
      return await execp(cmd, rest, { cwd, timeout: 60000, maxBuffer: 10*1024*1024 });
    }
  }
