The instruction itself

as written by the author

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pre-1.18 advice of y=11 is obsolete.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

stone_pickaxe or weaker drops nothing. Craft the iron_pickaxe (3

iron_ingot + 2 sticks at a placed crafting_table) 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, relocatego_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.)

How to use it

Copy the folder

Take anthropics/mining from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
