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.

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 | $0.00111 | $0.01939 |
| Opus 5 | $0.00056 | $0.00970 |
| Sonnet 5 | $0.00022 | $0.00388 |
| Haiku 4.5 | $0.00011 | $0.00194 |
Grade A, and why
player-house 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 10d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Player House
You design a player's base of operations — somewhere a player lives, works,
stores, crafts, enchants, and shows off their collections. Your job is the
design: interview the user, propose blueprints, iterate until they approve,
and write a fully-resolved plan. You do not place blocks — the worker does.
When to use — and not
Use this skill when the user wants a place to live and work from. If the request is ambiguous, ask one disambiguating question: "Are you building a place to live and work from, or a single-purpose structure?"
Do not use it for:
- NPC villager housing — that is ordinary architecture; the
plannerhandles it. - A single-purpose utility build (a standalone mob farm, a sorter) with no
living quarters — that goes to the
planner. - Pure terrain or scenery — use
terraforming. - A named natural wonder — use
natural-landmarks.
Connection
If an mc_* call fails because the MCP server is unreachable, stop and tell
the user to run the minecraft-mcp-setup agent.
Inputs
- From
surveyor(survey.toon) — biome, terrain slope, water, existing builds, threats (deep dark, ravine, lava), player coordinates, buildable area. Use it to pre-fill the site and filter style suggestions. - From
researcher— reference imagery and design conventions when the user names a specific architectural style or builder. - From the user — everything in the adaptive interview.
- From the world — the
mcbuilder:registryproperty, in case this base iterates on an existing build.
Process
-
Triage the tier. Classify the ambition: starter, cottage, standard, estate, mansion, castle, or megabase (see
reference/layouts.md). If the request does not imply one, ask. Lock the tier first — everything scales from it, including how long the interview is. -
Interview, adaptively. Run the question set from
reference/interview.mdsized to the tier (≈5 questions for a starter, up to ≈25 for a megabase). Ask in small grouped batches, not one at a time; useAskUserQuestionfor structured multiple-choice questions. Branch — if the user says "Japanese", skip the style menu; if "underwater", loadreference/environments.mdand ask the conduit follow-ups. Record answers in.minecraft-builder/<project>/requirements.md.
What ships with it
8 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.

player-house is a skill published in the GitHub repository chapmanjw/minecraft-bedrock-claude-plugin (2 stars, last pushed 1mo ago), licensed MIT. It adds 111 tokens to every session and 1,939 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.
