Diamond ore generation peaks at y ≈ -58 in Minecraft 1.18+. The pre-1.18 advice of y=11 is obsolete.
Below y=0, the ore is almost always deepslate_diamond_ore, not diamond_ore — search for both names.
An iron_pickaxe is required — diamond ore mined with a stonepickaxe or weaker drops nothing. Craft the ironpickaxe (3 ironingot + 2 sticks at a placed craftingtable) before mining diamond. A diamond_pickaxe is not required.
To descend quickly, call go_near with your current x/z and a deep y (e.g. {"pos": {"x": <x>, "y": -55, "z": <z>}}) — the pathfinder digs straight down in one action. Don't mine_block stone repeatedly to descend; it wastes turns and pickaxe durability.
After exhausting a vein, relocate — go_near to a position 30+ blocks away horizontally at the same y before searching again. Diamond veins do not cluster; tunneling the same corridor repeatedly wastes turns.
(This skill is intentionally minimal. It's an example of what attaching a skill does — it puts these facts in the agent's context. Edit this file to add more, or write strategy directly in your AGENT['system'] prompt.)
