Implementation Reference

• src/commands/hybrid-pipeline.ts:103-130 (handler)

  Core handler function: runs Ruby to require review-ext.rb and inspects $LOADED_FEATURES for loaded review extensions.

  export async function checkRubyExtensionsCommand(options: { cwd: string }) {
    const { cwd } = options;
  
    try {
      const result = await runCommand("ruby", [
        "-r", "./review-ext.rb",
        "-e", "puts 'Extensions loaded: ' + $LOADED_FEATURES.grep(/review/).join(', ')"
      ], { 
        cwd, 
        env: { ...process.env, DEBUG: "1" }
      });
  
      const extensionsLoaded = result.stdout.includes("Extensions loaded");
      const loadedFiles = result.stdout.match(/Extensions loaded: (.+)/)?.[1] || "";
  
      return {
        success: extensionsLoaded,
        loadedExtensions: loadedFiles.split(", ").filter(Boolean),
        output: result.stdout
      };
    } catch (error: any) {
      return {
        success: false,
        error: error.message,
        stderr: error.stderr
      };
    }
  }

• src/index.ts:343-351 (schema)

  Tool schema: defines name, description, and input schema (cwd).

  {
    name: "review.check-ruby-extensions",
    description: "Verify Ruby extensions (ReviewExtention) are loaded correctly",
    inputSchema: {
      type: "object",
      properties: { cwd: { type: "string" } },
      required: ["cwd"]
    }
  },

• src/index.ts:570-579 (registration)

  Registration in CallToolRequestSchema handler: dispatches to hybridCommands.checkRubyExtensions.

  case "review.check-ruby-extensions": {
    const result = await hybridCommands.checkRubyExtensions({
      cwd: args.cwd as string
    });
    return {
      content: [
        { type: "text", text: JSON.stringify(result) }
      ]
    };
  }
