xlsx
by ImGoodBai
"Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When Claude needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas"
tooyoung:threejs-builder
by shiqkuangsan
"Creates simple Three.js web apps with scene setup, lighting, geometries, materials, animations, and responsive rendering. Use for 'Create a threejs scene/app/showcase' or when user wants 3D web content. Supports ES modules, modern Three.js r170+ APIs."
test-calculate
by bdambrosio
Tests calculate tool with arithmetic, trig, and variable substitution
Excalidraw Generation
by rhuss
This skill should be used when the user asks to "create excalidraw diagram", "generate excalidraw", "hand-drawn diagram", "sketch diagram", "whiteboard style diagram", or when informal, spatial, annotated diagrams would best convey conceptual relationships. Expert in both presentation design AND artistic Excalidraw JSON creation.
camera-shake
by verekia
Shake the camera when the player takes damage or on impacts for visual feedback.
smooth-interpolation
by verekia
Animate values smoothly using exponential decay instead of linear interpolation.
weapon-trail
by verekia
Create a ribbon trail effect that follows a weapon's movement.

particles-lifecycle
by Bbeierle12
Particle lifecycle management—emission/spawning, death conditions, object pooling, trails, fade-in/out, and state transitions. Use when particles need birth/death cycles, continuous emission, trail effects, or memory-efficient recycling.
particles-gpu
by Bbeierle12
GPU-based particle systems using instanced rendering, buffer attributes, Points geometry, and custom shaders. Use when rendering thousands to millions of particles efficiently, creating particle effects like snow, rain, stars, or abstract visualizations.
particles-physics
by Bbeierle12
Physics simulation for particle systems—forces (gravity, wind, drag), attractors/repulsors, velocity fields, turbulence, and collision. Use when particles need realistic or artistic motion, swarm behavior, or field-based animation.
audio-analysis
by Bbeierle12
Audio analysis with Tone.js and Web Audio API including FFT, frequency data extraction, amplitude measurement, and waveform analysis. Use when extracting audio data for visualizations, beat detection, or any audio-reactive features.
math-tools
by ananddtyagi
Deterministic mathematical computation using SymPy. Use for ANY math operation requiring exact/verified results - basic arithmetic, algebra (simplify, expand, factor, solve equations), calculus (derivatives, integrals, limits, series), linear algebra (matrices, determinants, eigenvalues), trigonometry, number theory (primes, GCD/LCM, factorization), and statistics. Ensures mathematical accuracy by using symbolic computation rather than LLM estimation.
