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

spatial-developer 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 4d 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.

WebXR Basics

npm install three @react-three/fiber @react-three/drei @react-three/xr

Simple VR Scene

// components/VRScene.tsx
'use client'
import { Canvas } from '@react-three/fiber'
import { VRButton, XR, Controllers, Hands } from '@react-three/xr'
import { Box, OrbitControls } from '@react-three/drei'

export function VRScene() {
  return (
    <>
      <VRButton />
      <Canvas>
        <XR>
          <ambientLight intensity={0.5} />
          <pointLight position={[10, 10, 10]} />

          {/* 3D Content */}
          <Box position={[0, 1, -2]} args={[1, 1, 1]}>
            <meshStandardMaterial color="hotpink" />
          </Box>

          {/* VR Controllers */}
          <Controllers />

          {/* Hand Tracking */}
          <Hands />
        </XR>
      </Canvas>
    </>
  )
}

AR on Web (WebXR)

// components/ARScene.tsx
'use client'
import { Canvas } from '@react-three/fiber'
import { ARButton, XR } from '@react-three/xr'
import { useState } from 'react'

export function ARScene() {
  const [hitTest, setHitTest] = useState(null)

  return (
    <>
      <ARButton
        sessionInit={{
          requiredFeatures: ['hit-test'],
          optionalFeatures: ['dom-overlay']
        }}
      />

      <Canvas>
        <XR
          onHitTest={(hitMatrix, hit) => {
            setHitTest(hit)
          }}
        >
          <ambientLight />

          {hitTest && (
            <mesh position={hitTest.position}>
              <sphereGeometry args={[0.1]} />
              <meshStandardMaterial color="blue" />
            </mesh>
          )}
        </XR>
      </Canvas>
    </>
  )
}

What ships with it

2 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.
