procedural-clouds
by CK42BB
Generate beautiful procedural clouds in Three.js using WebGPU raymarching with WebGL2 billboard/mesh fallbacks. Covers all 10 major cloud genera (cumulus, stratus, cirrus, cumulonimbus, stratocumulus, altocumulus, altostratus, nimbostratus, cirrostratus, cirrocumulus) with physically-inspired lighting including silver linings, god rays, sunset coloring, and Mie/Rayleigh scattering approximation. Provides volumetric raymarching, billboard impostor, and mesh-cluster rendering paths with animated drift, morphing, and dynamic formation/dissipation. Use when building skies, cloudscapes, weather systems, flight scenes, atmospheric backgrounds, or any scene requiring clouds. Triggers: "procedural clouds", "cloud rendering", "volumetric clouds", "skybox clouds", "cloudscape", "cumulus", "cirrus", "storm clouds", "cloud shader", "cloud billboard", "raymarched clouds", "cloud lighting", "god rays", "sky rendering".
pyscf
by silico-quantum
PySCF (Python-based Simulations of Chemistry Framework) — modular pure-Python quantum chemistry library. Supports HF, DFT, MP2, CCSD, CCSD(T), CASSCF, TDDFT, geometry optimization, PES scanning, and spectroscopy. Based on pyscf.org documentation.
remotion-performance-optimizer
by ncklrs
Analyzes Remotion compositions for performance issues and provides optimization recommendations. Identifies expensive computations, unnecessary re-renders, large assets, memoization opportunities, and architecture improvements. Use when optimizing render times or when asked to "improve performance", "speed up renders", "optimize Remotion video".
xlsx-editor
by Exploration-labs
Specialized guidance for editing EXISTING Excel files with emphasis on preserving formulas, formatting, and structure across multiple tabs. Use this skill when modifying, updating, or adding data to existing .xlsx files where maintaining integrity is critical—particularly for multi-tab workbooks, complex formulas, formatted tables, and data that must maintain sort order and relationships across sheets.
uniswap-fundamentals
by rustydotwtf
Reference for Uniswap V3/V4 concepts used in Doppler development, including tick math, sqrtPriceX96, concentrated liquidity formulas, and V4 hooks/singleton architecture.
groove
by mbilokonsky
[PLACEHOLDER - skill not yet fully defined] The groovy commutator is a formal detector for edge-of-chaos dynamics—systems where order of operations matters in structured (not random) ways. This is the signature of aliveness. J Dilla saw what Heisenberg saw, and it shows up in Class 4 cellular automata, jazz micro-timing, quantum mechanics, and semantic navigation.
blockbench-modeling
by jasonjgardner
Create and edit 3D models in Blockbench using MCP tools. Use when building geometry with cubes, creating meshes, placing spheres/cylinders, editing vertices, extruding faces, or organizing models with groups. Covers both cube-based Minecraft modeling and freeform mesh editing.
Maintaining Consistent Abstractions
by obra
Class interfaces present one cohesive abstraction - don't mix domain logic with serialization, persistence, or unrelated concerns
readability
by humanizerai
Analyze text readability with Flesch-Kincaid, Gunning Fog, SMOG, and other metrics. Returns objective scores with interpretation and recommendations.
word-stats
by humanizerai
Get word count, character count, reading time, and text statistics. Quick analysis without questions.
