Implementation Reference

• server.js:702-829 (handler)

  Main handler function for 'warden_composer' tool. Executes Composer commands inside the Warden php-fpm container. Checks for composer2 or composer availability and version (requires v2), parses command arguments, runs via 'warden env exec', and returns structured output with success status.

  async runComposer(args) {
    const { project_path, command } = args;
  
    if (!project_path) {
      throw new Error("project_path is required");

    }
  
    const normalizedProjectPath = project_path.replace(/\/+$/, "");
    const absoluteProjectPath = resolve(normalizedProjectPath);
  
    if (!existsSync(absoluteProjectPath)) {
      throw new Error(
        `Project directory does not exist: ${absoluteProjectPath}`,
      );
    }
