threejs
Build immersive 3D web experiences with Three.js - WebGL/WebGPU library for scenes, cameras, geometries, materials, lights, animations, loaders, post-processing, shaders (including node-based TSL), compute, physics, VR/XR, and advanced rendering. Use when creating 3D visualizations, games, interactive graphics, data viz, product configurators, architectural walkthroughs, or WebGL/WebGPU applications. Covers OrbitControls, GLTF/FBX loading, PBR materials, shadow mapping, post-processing effects (bloom, SSAO, SSR), custom shaders, instancing, LOD, animation systems, and WebXR.
mobile-development
Build modern mobile applications with React Native, Flutter, Swift/SwiftUI, and Kotlin/Jetpack Compose. Covers mobile-first design principles, performance optimization (battery, memory, network), offline-first architecture, platform-specific guidelines (iOS HIG, Material Design), testing strategies, security best practices, accessibility, app store deployment, and mobile development mindset. Use when building mobile apps, implementing mobile UX patterns, optimizing for mobile constraints, or making native vs cross-platform decisions.
single-file-uv-scripter
Creates self-contained Python scripts with inline PEP 723 metadata for UV. Embeds dependencies directly in script headers for zero-config execution via `uv run`. Triggers on keywords: uv script, single file script, inline dependencies, PEP 723, self-contained python, uv run script, standalone script
python-project-skel
Generate production-ready Python project skeletons with Astral UV package manager, Hatchling build backend with dynamic versioning, and modern tooling (ruff, mypy, pytest, bandit). Use when creating new Python projects, initializing Python packages, setting up src-layout projects, scaffolding Python libraries, or starting a new Python application. Supports Python 3.14+ by default with configurable version. Output to current directory, specified path, or tarball.
dry-run
Simulates command execution in dry-run mode without file modifications. Sets dry_run flag, executes command with read-only constraint, then resets flag. Useful for testing workflows safely. Triggers on keywords: dry run, simulate, test command, preview changes, safe mode, no write
memory
Long-term memory across sessions. Always use memory_search at the start of any user request (unless the user explicitly says not to), especially for questions about the user (profile/personal info/preferences), prior constraints or decisions, and resuming ongoing work; use memory_write only when the user explicitly asks to store memory.
workflow-skill
Demonstrates script and custom tool working together with console output
python-script
Create robust Python automation with full logging and safety checks. Use when tasks need complex data processing, authenticated API work, conditional file operations, or error handling beyond simple shell commands.
stripe-handler
Handle Stripe payments, webhooks, and subscriptions.
burn-token
Use when user wants to burn tokens aggressively - infinite loop of analysis, summarization, or heavy math computation. Maximizes token consumption by defeating KV cache, randomizing prompts, and dispatching verbose subagents. Supports time limits, round limits, or unlimited burn until interrupted.
tailwind-shadcn-adaptation
Adapt ShadCN primitives to design-system tokens. Use when importing or normalizing ShadCN components in a UI primitives directory and before creating product wrappers.
add-language-support
Implements mutation testing support for new programming languages using tree-sitter grammars and the LanguageEngine trait. Triggers on "add language support", "add [language] support", "implement [language]", "new language", or mentions of specific languages like Python, TypeScript, C++, Java.
egret
Progressive-disclosure workflow for Egret optimization studies. Use when the user asks to run DC OPF, AC OPF, or unit commitment through PowerMCP, and when the agent should solve the simplest credible optimization before escalating to full commitment studies.
typescript-expert
TypeScript infrastructure specialist for monorepo project references, type performance diagnostics (tsc --extendedDiagnostics), ESM/CJS interop, strict mode migration, and .d.ts authoring — use for project-level TypeScript decisions, not implementation patterns.
flutter-template-upgrade
Upgrade Flutter and package dependencies in this repository while keeping .fvmrc, pubspec.yaml, code generation, CI, and tests aligned. Use when bumping Flutter, Dart constraints, direct dependencies, or generator toolchains.
marimo-notebook
Write a marimo notebook in a Python file in the right format.
flutter-template-release-prepare
Prepare a release in this repository by bumping the app version, updating release notes, creating a release branch named release/<version>, and preparing the PR for merge before any release builds or tags are created.
