mvtt: Skill for Claude Code

.agents/skills/pixijs-scene-core-concepts/SKILL.md

pixijs-scene-core-concepts is a skill for Claude Code, Codex from adamhjk/mvtt. It costs 126 tokens per session (3,542 once invoked), scanned A, original, no licence file.

A guide to the main parts of a PixiJS v8 scene graph, the tree that organizes objects in a rendered application. It explains how containers, visible objects, positions, ordering, masking, and rendering groups relate to one another.

In plain words
What is it for?
Use it when designing or debugging PixiJS scenes, including transforms, culling, child ordering, masking, render layers, and render groups.
Why use it?
Scene graphs involve several kinds of objects and coordinate systems that can be easy to mix up. This helps explain how changes to one scene node affect its position and rendering.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is adamhjk/mvtt's own configuration. It tells Claude Code and Codex how to work on mvtt itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mvtt configures →

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

pixijs-scene-core-concepts 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 11d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
