Instructions

Implementation Reference

• src/tools/smembers_tool.ts:21-35 (handler)

  The execute method implements the smembers tool logic: validates args, calls Redis client.sMembers(key), handles empty set or errors, returns formatted members or messages.

  async execute(args: unknown, client: RedisClientType): Promise<ToolResponse> {
    if (!this.validateArgs(args)) {
      return this.createErrorResponse('Invalid arguments for smembers');
    }
  
    try {
      const members = await client.sMembers(args.key);
      if (members.length === 0) {
        return this.createSuccessResponse('Set is empty or does not exist');
      }
      return this.createSuccessResponse(JSON.stringify(members, null, 2));
    } catch (error) {
      return this.createErrorResponse(`Failed to get set members: ${error}`);
    }
  }
