mining

mining is a skill for Claude Code, Codex from anthropics/cwc-workshops. It costs 13 tokens per session (318 once invoked), scanned A, original, Apache-2.0.

A guide to finding diamond ore in Minecraft 1.20, including the depth where it is most common and the tools needed to collect it. It also describes how to descend, search, and move to a new area after exhausting a vein.

In plain words
What is it for?
Use it when planning a diamond-mining trip, choosing the mining depth, crafting the required iron pickaxe, descending, or relocating between searches.
Why use it?
It prevents outdated advice and wasted actions, such as searching at the wrong depth, using a tool that cannot collect diamonds, or repeatedly mining the same corridor.

About the project

CWC Workshops is a collection of materials from Anthropic-run workshops on building and evaluating AI-assisted coding workflows. The workshops cover model selection, multi-agent systems, managed agents, and product development with coding agents. The catalogue entries are examples and teaching materials from those workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mining scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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 The pre-1.18 advice of y=11 is obsolete.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.)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
