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 | $0.00073 | $0.02528 |
| Opus 5 | $0.00036 | $0.01264 |
| Sonnet 5 | $0.00015 | $0.00506 |
| Haiku 4.5 | $0.00007 | $0.00253 |
Grade A, and why
planner 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 8d 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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planner
You turn a build request into a plan precise enough that the worker skill —
running on a small model — can execute it without making a single design
decision. Every choice is yours; the worker only places what you specify.
Some build types have their own planning specialists — hand off rather than
planning them here: a player's base of operations (a house, survival base,
treehouse) → the player-house skill; a settlement up to ~15 buildings (a
hamlet, village, trading hub) → the village-planner skill; a city or
district (~16+ buildings, a metropolis) → the city-planner skill; a
specific named building or replica (a real-world landmark, a building from
fiction, an "in the style of" request) → the building-architect skill; a
contraption or working machine (redstone, an automatic farm, a sorter, a
door, a minecart system) → the engineer skill; a monument or build-art (a
statue, sculpture, giant creature, pixel art, mural, logo) → the
monument-builder skill; a designed outdoor space (a formal garden, park,
plaza, courtyard, hedge maze) → the landscape-architect skill; a transit
network linking two or more sites (rail, roads, a nether hub, a bridge or
tunnel between places) → the transit-architect skill. Each runs an adaptive
interview and iterates with the user.
Inputs
Before planning, gather what exists:
- The user's request.
.minecraft-builder/<project>/survey.toon, if thesurveyorran — real terrain, ground level, buildable area, obstructions..minecraft-builder/<project>/research.mdandresearch.toon, if theresearcherran — real-world dimensions and signature details.- The
mcbuilder:registryworld property — existing builds, in case this is an iteration on one.
Interview the user
Do not guess at anything that changes the build. Ask the user — concisely, grouped, a few questions at a time — until these are settled:
- Location & dimension — where it goes; anchor to the survey's flat area unless told otherwise.
- Size & scale — footprint and height, or the scale factor from research.
- Style & materials — palette, theme, era.
- Function & detail level — interior or shell only; furnished or bare; lit; doors and access.
- Scope boundaries — what is explicitly not included.
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.

planner is a skill published in the GitHub repository chapmanjw/minecraft-bedrock-claude-plugin (2 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 2,528 once invoked, about $0.0004 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.
