Third-Person-MC: Skill for Claude Code

.agent/skills/vtj-debug-panel/SKILL.md

vtj-debug-panel is a skill for Claude Code, Codex from hexianWeb/Third-Person-MC. It costs 36 tokens per session (654 once invoked), scanned A, original, MIT.

A Tweakpane debug-panel setup for changing 3D component parameters while the application runs. The panels appear when the page URL contains the #debug flag.

In plain words
What is it for?
Use it to adjust numbers and colors, inspect runtime values, control points and booleans, choose options, and add debugging buttons to 3D components.
Why use it?
It avoids repeatedly editing code and reloading the app to tune values or inspect component state.

Written for no agent in particular: nothing here depends on one.

This is hexianWeb/Third-Person-MC's own configuration. It tells Claude Code and Codex how to work on Third-Person-MC 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 Third-Person-MC configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

vtj-debug-panel 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 2mo 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.

vite-threejs Debug Panel (Tweakpane)

Overview

Creates real-time parameter adjustment panels using Tweakpane. Activated via #debug URL hash.

Core principles:

  • Every tunable parameter gets a control
  • Colors must use view: 'color'
  • Group panels hierarchically (max 3 levels)

Quick Start

constructor() {
  this.experience = new Experience()
  this.debug = this.experience.debug
  
  this.params = { intensity: 1.0, color: '#ffffff' }
  
  if (this.debug.active) {
    this.debugInit()
  }
}

debugInit() {
  this.debugFolder = this.debug.ui.addFolder({
    title: 'Component Name',
    expanded: false,
  })
  
  this.debugFolder.addBinding(this.params, 'intensity', {
    min: 0, max: 10, step: 0.1,
  })
}

When to Use

  • Creating new 3D components
  • Adding ShaderMaterial uniform controls
  • Monitoring runtime state
  • Adding action buttons

Control Types

Type Key Config
Number min, max, step
Color view: 'color' (required)
3D Point view: 'point3d'
Boolean No extra config
Select options: { label: value }
Button addButton({ title })

Detailed examples: See references/controls.md

ShaderMaterial Integration

All ShaderMaterial uniforms must have debug controls:

folder.addBinding(this.params, 'color', { view: 'color' })
  .on('change', (ev) => {
    this.material.uniforms.uColor.value.set(ev.value)
  })

Full patterns: See references/shader-debug.md

Common Mistakes

  • ❌ Colors without view: 'color'
  • ❌ Direct this.debug.ui extraction
  • ❌ Calling debugInit() without checking debug.active
  • ❌ Nesting deeper than 3 levels
  • ❌ All panels expanded by default

Complete error catalog: See references/common-mistakes.md

Quick Reference

Need Code
Access debug this.debug = this.experience.debug
Check active if (this.debug.active)
Create folder this.debug.ui.addFolder({ title })
Bind parameter folder.addBinding(params, 'key', options)
Handle change .on('change', callback)
Method name debugInit()

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.
