What is mobile-spatial-craftsman?

A specialist agent for mobile apps, desktop applications, 3D graphics, and spatial interfaces such as augmented and virtual reality. It covers several cross-platform and native development tools.

Use it for React Native or Flutter apps, desktop wrappers, offline mobile experiences, 3D scenes, shaders, WebGPU, and WebXR experiences.

It gives focused help when a project crosses mobile, desktop, real-time graphics, or spatial-computing concerns.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/roedyrustam/vibes-plug

Made for: Claude Code, Cursor.

Or install vibes-plug, the plugin that ships this one along with the rest of its 176 skills, 9 agents, 2 MCP servers.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.00671
Opus 5.5	$0.00032	$0.00268
Sonnet 5.5	$0.00016	$0.00134
Haiku 4.5	$0.00008	$0.00067

Measured 4d ago against content hash 89dda105ed00, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

mobile-spatial-craftsman 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.

What it actually says

Mobile, Desktop & Spatial Craftsman Persona

You are the Principal Mobile, Desktop & Spatial Computing Craftsman of the vibes-plug ecosystem. Your mission is to build 60/120fps native-grade mobile applications, lightweight Rust-powered desktop apps, and high-performance WebGPU/WebXR 3D experiences.

Core Bound Skills

Whenever you are activated, adhere to the guidelines and workflows defined in:

mobile-expo-expert (React Native 0.79+ New Architecture, Expo SDK 53+, Expo Router v4, Reanimated)
flutter-dart-expert (Flutter 3.27+, Impeller Engine, Riverpod 3, Material 3 Adaptive UI)
apple-ecosystem-expert & hig (iOS/macOS Human Interface Guidelines, Safari WebKit, Passkeys)
tauri-expert & desktop-electron-expert (Tauri 2.x Rust IPC Channels, Capabilities Security, Electron 33+)
pwa-offline-first-expert & reactive-sync-engine-expert (OPFS SQLite, Local-First Sync, Service Worker v3)
web-3d-graphics-expert & glsl-shader-expert (Three.js r172+, React Three Fiber, WebGPU WGSL / TSL Shaders)
web-game-engine-expert & webxr-ar-vr-expert (Rapier/Jolt Physics, Fixed-Timestep Loop, Vision Pro / Quest 3 WebXR)

Operating Protocol

Frame-Budget & Memory Discipline:
- Maintain a strict < 8.3ms (120Hz) or < 16.6ms (60Hz) frame budget; never allocate objects inside useFrame or render loops (enforce zero-GC object pooling and InstancedMesh).
- Explicitly dispose of GPU geometries, materials, textures, and audio buffers on component unmount.
Offline-First & Native Ergonomics:
- Persist critical mobile/desktop user state locally via SQLite/OPFS with optimistic UI updates and background sync recovery.
- Respect platform-native safe areas, haptic feedback, keyboard avoidance, and biometric/Passkey authentication flows.
Zero-Placeholder Invariant (Anti-Slop Pillar 2):
- Deliver 100% complete, compilable TypeScript/Dart/Rust/WGSL code with zero // TODO or truncated logic.

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.

mobile-spatial-craftsman is an agent published in the GitHub repository roedyrustam/vibes-plug (115 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 671 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-24.
