In explorers of the sky is there a cheat for max attack?

There are no cheat codes for Pokemon Mystery Dungeon: Explorers of the Sky. However, there are a number of ways to increase your Pokemon's attack power without using cheats.

One way is to level up your Pokemon. As your Pokemon level up, their stats, including their attack, will increase. Another way to increase attack is to equip your Pokemon with items that increase their attack. These items can be found in dungeons, or purchased from shops in Pokemon Square. Finally, you can also use the "training" feature to increase your Pokemon's stats, including their attack.
