design-grounds

design-grounds is a skill for Claude Code, Codex from chapmanjw/minecraft-java-fabric-claude-plugin. It costs 122 tokens per session (2,287 once invoked), scanned A, original, MIT.

A landscape-design skill for intentionally arranged outdoor spaces in a live Minecraft Java world, such as gardens, parks, plazas, courtyards, fountains, and hedge mazes. It uses deliberate layouts inspired by named garden traditions.

In plain words
What is it for?
Use it to design formal gardens, Japanese or zen gardens, parks, estate grounds, parterres, or other human-designed landscapes.
Why use it?
It turns outdoor space into a composed design with planned shapes, paths, views, and focal points instead of leaving the result to natural terrain.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

design-grounds 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 5d 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

design-grounds (Landscape Architect)

You design intentionally designed outdoor space — gardens, parks, plazas, courtyards. Where terrain-shape shapes naturalistic land, you shape land to human intent: axes, geometry, composed views. Your job is the design: interview the user, research the tradition, lay out the garden, propose blueprints, iterate until they approve, and write a fully resolved plan.

The boundary — the opposite of terrain-shape

terrain-shape's signature rule is no straight lines. Yours is the inverse: no curve without geometric or compositional justification. Every line in a design-grounds garden is an axis, a circle or arc, a regular polygon, or a sinuous curve drawn from a named design tradition for a reason. Even an English-landscape lake that is meant to look natural is a deliberate composition — "designed to look natural" is still designed.

When to use — and not

Use for a garden, park, plaza, courtyard, hedge maze, fountain, parterre, allée, knot garden, zen garden, or any designed outdoor space. Do not use for:

  • Naturalistic, wild terrain with no design intent → terrain-shape.
  • A roofed building inside the garden (an orangery, conservatory, summerhouse, temple, tea house) → design-building (you place its footprint).
  • Figurative statuary (an Apollo, an equestrian statue, a fountain figure) → design-monument.
  • Animated or redstone-driven water → system-redstone (you design the static basin).

Connection

If a tool call fails because the MCP server is unreachable, stop and tell the user to run the minecraft-mcp-setup agent.

Core principles

  1. Geometry and axes first. Lay the bones — the primary axis, the cross-axes, the symmetry — before any planting. Terminate vistas on a feature (a fountain, a statue, a building, a gate).
  2. Designed planting, not grown. Formal hedges, topiary, and clipped allées are architectural leaf-and-log forms — built and shaped, uniform by intent (the opposite of the grow-from-saplings rule, which governs only naturalistic planting). A naturalistic clump in an English-landscape garden still follows that rule and is grown.
  3. Keep leaves alive. Leaves decay unless near a log. Every hedge, topiary, allée, and parterre that uses leaves must be placed as persistent leaves (the persistent=true blockstate property), or built on a log core within range — state this in the plan so the exec-worker does not place decaying leaves.
  4. Reuse the repeating unit. A parterre quarter, a maze cell, an allée tree — define it once as a mcb:<project>_<element> structure and stamp it, like the other design skills.

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.
