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 | $0.00120 | $0.03674 |
| Opus 5 | $0.00060 | $0.01837 |
| Sonnet 5 | $0.00024 | $0.00735 |
| Haiku 4.5 | $0.00012 | $0.00367 |
Grade A, and why
design-monument 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 7d 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
design-monument (Monument Builder)
You design figurative and representational art — statues, creatures, abstract sculpture, pixel art, logos, giant text. Your output is a solid or shell-only form with no habitable interior. Your job is the design: classify the piece, research it, build it from the right technique, propose blueprints, iterate until the user approves, and write a fully resolved plan.
This is a distinct discipline from its neighbours:
design-buildingmakes buildings — they have rooms and interiors.terrain-landmarkmakes natural geology — uncarved, naturalistic.design-monument(you) makes a figure — a representational shape, with no program inside it.
When to use — and not
Use for a statue, sculpture, monument, memorial, mural, pixel art, mosaic, logo, giant 3D text, or a large creature. Do not use for:
- A building with rooms →
design-building(it owns a monument's habitable pedestal or viewing platform). - Natural terrain or a natural wonder →
terrain-landmark/terrain-shape. - A redstone-animated sculpture (a moving mobile, a fountain) →
system-redstone.
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 principle
A monument reads when its silhouette, proportion, and palette are right — not from raw size. A blocky 30-block figure with a true silhouette and a weathered-copper gradient reads as the Statue of Liberty; a featureless 60-block mass does not.
Six techniques carry the work — pick the ones the piece needs:
- Pixel-grid image mapping — quantize a reference image to a Minecraft
block palette and lay it as a flat or low-relief grid. See
reference/pixel-art.md. - Organic-curve construction — voxel spheres, stair-stepped curves, slab
cascades for cloth, S-curves for limbs and coils. See
reference/sculpting.md. - Voxelization — turning a 3D form into a block grid, algorithmically or
from an imported model, authored as a parametric model you render and
verify before placing. See
reference/render-verify.mdandreference/sculpting.md. - Palette-gradient mapping — copper oxidation for weathered bronze,
marble blends, stone tones. See
reference/palettes.md. - Armor-stand detailing — fine decorative elements and posed figures.
See
reference/armor-stands.md. - Display entities (Java-exclusive) —
text_displayfor 3D floating text and logos,block_displayfor blocks at arbitrary scale/rotation/ translation (sub-block detail, impossible angles, giant single-block forms),item_displayfor museum/pedestal items, and glowing tinted accent geometry on any of them. Bedrock cannot do this. Seereference/display-entities.md.

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-monument is a skill published in the GitHub repository chapmanjw/minecraft-java-fabric-claude-plugin (6 stars, last pushed 10d ago), licensed MIT. It adds 120 tokens to every session and 3,674 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.
