anthropics/mining
Where diamonds spawn in Minecraft 1.20.
npx skills add https://github.com/anthropics/cwc-workshops --skill mining
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pre-1.18 advice of y=11 is obsolete.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, 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.

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