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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.00318 |
| Opus 5.5 | $0.00005 | $0.00127 |
| Sonnet 5.5 | $0.00003 | $0.00064 |
| Haiku 4.5 | $0.00001 | $0.00032 |
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 1mo 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 The pre-1.18 advice of y=11 is obsolete.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, 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.)
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.

mining is a skill published in the GitHub repository anthropics/cwc-workshops (2,210 stars, last pushed 6d ago), licensed Apache-2.0. It adds 13 tokens to every session and 318 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Structured playtest report template, or turn existing playtest notes into structured feedback.
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…

unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
