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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00146 | $0.01605 |
| Opus 5 | $0.00073 | $0.00803 |
| Sonnet 5 | $0.00029 | $0.00321 |
| Haiku 4.5 | $0.00015 | $0.00161 |
Grade A, and why
blockbench-use 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 9d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blockbench Use
Orchestrator for Blockbench MCP work. Load this before touching the 3D scene so the right sub-skills load and the right pre-flight checks run.
Rule
Any request that will call an mcp__blockbench__* tool to create or modify content must go through this skill first.
Steps, in order:
- Classify the request → pick one or more sub-skills (table below).
- Pre-flight → confirm a project is open and the format is correct (see "Pre-flight checks").
- Load the sub-skill(s) via the Skill tool.
- Checkpoint before risk → call
save_checkpointfor multi-step edits that might need rollback. - Execute the sub-skill's workflow.
- Close the loop → screenshot, validate (Hytale), or export if the user asked for a deliverable.
Skill routing table
Pick by primary intent. When the task spans domains, load all relevant skills before starting.
| User intent | Primary skill | Also load when… |
|---|---|---|
| Build cubes, meshes, groups, hierarchy | blockbench-modeling |
needs texture → blockbench-texturing |
| Paint, fill, draw, brush, layers, UV | blockbench-texturing |
channel-aware (normal/MER) → blockbench-pbr-materials |
| Keyframes, bone rigs, walk/idle/attack | blockbench-animation |
bones need geometry first → blockbench-modeling |
.texture_set.json, normal/height/MER |
blockbench-pbr-materials |
textures not yet drawn → blockbench-texturing |
.blockymodel, .blockyanim, attachments, quads, stretch, shading modes |
blockbench-hytale |
modeling/animation parts → those skills |
| "What tools are available?" / unclear scope | blockbench-mcp-overview |
— |
| Write a Blockbench JS plugin (not use MCP) | blockbench-plugins (from blockbench-development/) |
— |
Skip this skill for pure research questions (API docs, "how does Blockbench work?"). Go straight to blockbench-mcp-overview.
Pre-flight checks
Run before any mutation. One round of list_outline + list_textures is usually enough.
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.

blockbench-use is a skill published in the GitHub repository jasonjgardner/blockbench-mcp-project (15 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 146 tokens to every session and 1,605 once invoked, about $0.0007 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 2026-08-30.
