Procedural Starfield

Generate stunning procedural night skies, starfields, nebulae, and celestial phenomena in Three.js using WebGPU compute with WebGL2 fallback. Covers scientifically-grounded starfields with spectral color temperature, magnitude-based brightness, and twinkling; volumetric nebulae with emission/absorption/reflection types; the Milky Way band; constellations with optional line overlays; planets and moons with phase lighting; shooting stars and meteor showers; aurora integration; eclipses (solar and lunar); comets with ion/dust tails; galaxies as deep-sky backdrop objects; and a full sky dome contr

Redacta

nickjlamb/redacta

Pseudonymises medical and clinical documents by replacing patient identifiers with labelled tokens (e.g. [PATIENT_NAME_1], [NHS_NUMBER_1], [DATE_OF_BIRTH_1]) so the text can be safely processed by AI or shared, with clinical meaning intact. Combines a deterministic pattern layer (NHS numbers with Modulus-11 validation, UK National Insurance numbers, dates of birth, UK postcodes, phone numbers, emails, hospital/MRN numbers) with contextual reasoning for patient names, postal addresses and identifying ages, then returns the redacted document plus a redaction report. Use when the user wants to re

Pedagogical Grounding Engine

edu-ai-builders/pedagogical-grounding-engine

将一篇或多篇学术论文，通过"教学法约束推理"转化为有理论根基的产品设计产物。核心是构建"学术机制 → 约束交互 → 可解释推理链"的中间层，再导出多种格式的设计产物。本skill是一个 Pedagogical Grounding Engine（教学法落地引擎）：它不是论文摘要工具，而是把教学法意图（pedagogical intent）编译为可执行的系统设计结构。PRD、System Prompt、Workflow 都是下游导出格式，核心产物是 Traceability Map——每个设计决策都有明确的教学依据、认知机制和可追溯的设计理由。当用户有以下意图时触发本skill： - "把这篇/这几篇论文做成产品/app/提示词/工作流" - "paper to PRD / paper to prompt / paper to product" - "pedagogical grounding / 教学法落地" - "我想基于学习科学设计这个功能/系统提示词" - "从论文提取知识图谱/三元组/TPACK分析" - "我有几篇论文，帮我提炼成一个设计方案" - "帮我把教学法嵌入到产品/提示词中" - "生成 traceability 图" / "把这篇论文可视化" - "我有一个教学场景/教育想法，帮我设计成系统"（不一定有论文）支持 Commands 模式：流水线
