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.

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 | $0.00036 | $0.06777 |
| Opus 5 | $0.00018 | $0.03388 |
| Sonnet 5 | $0.00007 | $0.01355 |
| Haiku 4.5 | $0.00004 | $0.00678 |
Grade A, and why
threejs-bridge 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 today.
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 — 412 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Three.js Bridge
Use this skill when a task involves Pulp's native Three.js bridge or the
examples/threejs-native-demo workflow.
Truthful Position
Pulp now supports a native Three.js lane built on:
- the real MIT
three.webgpu.jsrenderer - Pulp's V8-backed JS engine
- the Dawn-backed native
GPUCanvasContextbridge - a visible native
WindowHostpath with no browser or WebView
Supported now:
- native demo modes in
examples/threejs-native-demo/main.cppcubegltf-boxspectrumparticlesribbonreverb
- real
THREE.WebGPURendererinitialization - native pointer drag, wheel zoom, and trackpad pinch on the demo canvas
- real
OrbitControlsaddon import/init on the native path - focused bridge validation in
test/web-compat/test_threejs_bridge.cpp - native one-shot screenshot capture via
--capture
Not supported by this skill:
- broad browser compatibility
- a full DOM implementation
- claims that all Three.js APIs or addons are already covered
- cross-platform live-parity claims beyond what the branch has actually proven
Critical Build Requirements
- V8 engine required — Three.js needs typed arrays, promises, and full ES
module support. Use Pulp's pinned, sealed v8-builder provider; do not use a
Homebrew
libnodefor acceptance. Fetch the matched platform asset once and enable the strict provider gate:
Verify the linked dylib and run the no-skip identity/capture gate before trusting a local Three.js result:python3 tools/scripts/fetch_v8_for_release.py darwin-arm64 cmake -S . -B build -DPULP_JS_ENGINE=v8 \ -DPULP_VALIDATE_V8_PROVIDER_STRICT=ON \ -DPULP_ENABLE_GPU=ON -DPULP_BUILD_TESTS=ONotool -L build/examples/threejs-native-demo/pulp-threejs-native-demo | grep libv8 ctest --test-dir build -R '^v8_provider_identity_strict$' --output-on-failureV8_DIRmay select a baked sealed provider. The legacyV8_INCLUDE_DIR,V8_LIB_DIR, andV8_LIBRARY_PATHoverrides are for explicit local experimentation only; results from Homebrewlibnodeare not acceptance evidence because its external ICU/Abseil surface can collide with Skia.
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.

threejs-bridge is a skill published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 6,777 once invoked, about $0.0002 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 2026-09-04.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
