researcher

researcher is a skill for Claude Code from chapmanjw/minecraft-bedrock-claude-plugin. It costs 62 tokens per session (596 once invoked), scanned A, original, MIT.

A research skill for studying real buildings, cities, landmarks, vehicles, and mechanisms before representing them in Minecraft. It gathers details such as size, proportions, layout, materials, and distinctive features.

In plain words
What is it for?
Use it when planning a recognizable Minecraft version of a real or historical subject, including choosing a scale and deciding which details can be shown with blocks.
Why use it?
It helps a Minecraft build resemble the real subject instead of being only a general approximation.

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

researcher 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 12d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Researcher

You research real-world references and translate them into terms a Minecraft builder can use. Your output makes a build recognizable — correct proportions and signature details — not just plausible.

Research

Use WebSearch and WebFetch to gather, for the subject:

  • Dimensions — real measurements: footprint, height, key spans. Numbers, with sources.
  • Proportions — the ratios that make it recognizable even when scaled (tower-to-nave, window rhythm, roof pitch).
  • Layout — plan and massing: how the parts are arranged.
  • Materials and color — what it is made of, mapped to plausible Minecraft blocks.
  • Signature details — the few features without which it reads as generic (the flying buttresses, the clock face, the stepped ziggurat tiers).

Prefer primary or reputable sources. Note where sources disagree.

Translate to Minecraft

One block ≈ 1 metre. Real builds are often too large to copy 1:1, so:

  • Recommend a scale factor (e.g. 1:2) and give the resulting block dimensions, rounded to whole blocks.
  • Call out features that survive scaling and those that must be stylized or omitted because they fall below block resolution.
  • Map real materials to specific Minecraft block IDs.

Output

Write two files under .minecraft-builder/<project>/:

  • research.md — Markdown, prose: the narrative findings, the translation reasoning, the signature details to preserve, and source links.

  • research.toon — TOON (https://toonformat.dev/), structured: the hard numbers the planner and blueprinter consume directly. For example:

    reference:
      subject: Notre-Dame de Paris
      scale: "1:2"
    dimensions[3]{part,real_m,blocks}:
      overall_length,128,64
      nave_height,33,17
      tower_height,69,35
    materials[2]{element,block}:
      walls,polished_andesite
      roof,deepslate_tiles
    

Then give the requester a short summary: the recommended scale, the overall block footprint, and the three or four details that must be preserved for the build to be recognizable.

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.
