blockbench-mcp-project: Skill for Claude Code

.claude/skills/blockbench-hytale/SKILL.md

blockbench-hytale is a skill for Claude Code from jasonjgardner/blockbench-mcp-project. It costs 58 tokens per session (1,715 once invoked), scanned A, original, Apache-2.0.

A set of Blockbench tools for creating models and animations for Hytale, a game that uses its own model format. It requires the Hytale plugin to be installed in Blockbench.

In plain words
What is it for?
Use it to create or validate Hytale characters and props, configure shading and stretching, make quads, manage attachment pieces, and create Hytale animation settings.
Why use it?
It handles Hytale-specific model properties and checks that general Blockbench tools may not cover. It also supports Hytale attachments and visibility changes in animations.

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

blockbench-hytale 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 10d 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.

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.
