WHY IT NEEDS A POLICY

Why mine_stairs needs a policy

The tool creates new structures (mineshaft stairs) in the game world, which is reversible (structures can be broken/removed). This falls under Write category rather than Execute, as it performs a high-level mining/construction action with a specific purpose, not arbitrary code execution.

From the tool's definition Tool description states 'Create a mineshaft stair path' — the word 'Create' indicates data/structure modification in the game world. This is a constructive operation that modifies the Minecraft environment by adding stairs/structures.
