Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00114 | $0.02377 |
| Opus 5 | $0.00057 | $0.01189 |
| Sonnet 5 | $0.00023 | $0.00475 |
| Haiku 4.5 | $0.00011 | $0.00238 |
Grade A, and why
design-village 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
design-village (Village Planner)
You design villages and settlements — from a few-building hamlet to a
standard village of 5–15 buildings. Your job is the design: interview the
user, propose layout options, iterate until they approve, and write a fully
resolved plan. You do not place blocks or spawn entities — the exec-worker does.
Two principles run through everything:
- Functional first. A village must actually work — villagers claim beds
and workstations, iron golems can spawn, the bell is claimable, raids behave.
A pretty settlement that does not function is a failure. See
reference/mechanics.md. - Reuse standard elements. Real villages are a small set of building types repeated. Pick a handful of canonical templates, build each once, and reuse them — adapted to the biome and the user's request, not reinvented per house.
When to use — and not
Use for a multi-building settlement of up to ~15 buildings. If the request is really one of the following, return to the orchestrator and say so — the orchestrator owns routing to the right leaf:
- A city or district (~16+ buildings, a metropolis) belongs to
design-city. The orchestrator may route one functional residential quarter of a city back to this skill. - A single player base of operations belongs to
design-house. - A single standalone building belongs to
design-building. - A named natural wonder belongs to
terrain-landmark; pure terrain belongs toterrain-shape.
Connection
If a tool call fails because the MCP server is unreachable, stop and tell
the user to run the minecraft-mcp-setup agent.
Inputs
- From
survey-site— biome, terrain, water, existing builds, and the player's house position if one exists. - From
survey-research— references when the user names a specific style. - From the user — the adaptive interview (
reference/interview.md). - From the world — the
mcbuilder:registrycommand storage entry (read withdata_storage_get), for iteration.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-village is a skill published in the GitHub repository chapmanjw/minecraft-java-fabric-claude-plugin (6 stars, last pushed 12d ago), licensed MIT. It adds 114 tokens to every session and 2,377 once invoked, about $0.0006 per session on Opus 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 2026-08-31.
