Test Go Gin APIs with httptest, table-driven tests, testcontainers. Use when writing tests for Gin handlers, services, middleware, or setting up integration and e2e tests.
MUST USE when designing ClickHouse architectures, selecting between ingestion or modeling patterns, or translating best practices into workload-specific system designs. Complements clickhouse-best-practices with decision frameworks and explicit provenance labels.
This skill should be used when the user asks to "create a 3D scene", "add a mesh", "implement OrbitControls", "load a GLTF model", "add bloom post-processing", "write a custom shader", "create particle effects", "optimize Three.js performance", "use WebGPU", "add shadows", "animate a model", or mentions Three.js, threejs, WebGL, WebGPU, GLTF, raycaster, shader material, PBR material, or post-processing effects. IMPORTANT: This skill is for VANILLA Three.js (imperative JavaScript). For React Three Fiber (@react-three/fiber, R3F, drei), check the `r3f-best-practices` skill, although three-js skills helps when working with R3F since R3F is a React renderer for Three.js. Provides complete Three.js reference for 3D web graphics including scene setup, geometry, materials, textures, lighting, cameras, loaders, animation, controls, interaction, shaders, post-processing, performance optimization, TSL/node materials, WebGPU, physics, and VR/XR integration.
Create educational videos using Remotion with Kurzgesagt/回形针 style. Use when users want to: (1) create teaching or educational videos, (2) design video storyboards, (3) produce animated explainer videos, (4) build SVG-based animations for learning content, (5) visualize complex concepts with motion graphics, (6) make science/tech explainer videos, (7) create 可视化讲解视频 or 科普视频. Triggers on requests like '帮我做一个教学视频', 'create an explainer video about X', '制作科普动画', 'make a video explaining Y'. This skill requires remotion-best-practices skill for technical implementation.
Build Next.js apps for the Whop platform. For empty repos, guides users from idea to deployed app through discovery and setup. For existing projects, provides best practices for authentication, payments, webhooks, and UI. Triggers on "build me a Whop app", @whop/sdk, verifyUserToken, checkAccess, checkout flows, webhook handling, Experience/Dashboard pages, Frosted UI. Delegates to companion skills (frontend-design, vercel-react-best-practices, supabase-postgres-best-practices, web-design-guidelines) for design, performance, and database.
Deployment procedures and CI/CD pipeline configuration for Python/React projects. Use when deploying to staging or production, creating CI/CD pipelines with GitHub Actions, troubleshooting deployment failures, or planning rollbacks. Covers pipeline stages (build/test/staging/production), environment promotion, pre-deployment validation, health checks, canary deployment, rollback procedures, and GitHub Actions workflows. Does NOT cover Docker image building (use docker-best-practices) or incident response (use incident-response).
Tailwind CSS v4.1 best practices with WCAG 2.1 AA accessibility, theming, and dark mode support. Use when working with HTML, CSS, styling components, accessibility (a11y), WCAG compliance, color contrast, focus states, screen readers, theming, light mode, dark mode, or building accessible UI patterns like buttons, forms, cards, and navigation. Complements the angular-best-practices skill for Angular frontends.
Security-focused code review checklist and automated scanning patterns. Use when reviewing pull requests for security issues, auditing authentication/authorization code, checking for OWASP Top 10 vulnerabilities, or validating input sanitization. Covers SQL injection prevention, XSS protection, CSRF tokens, authentication flow review, secrets detection, dependency vulnerability scanning, and secure coding patterns for Python (FastAPI) and React. Does NOT cover deployment security (use docker-best-practices) or incident handling (use incident-response).
Automatically apply improvements to skills and the ecosystem based on system-reviewer findings and best-practices-learner insights. Workflow for automated improvement identification, priority assessment, safe application, validation, and rollback capability. Use when applying systematic improvements, automating enhancement cycles, bulk updating multiple skills, or implementing ecosystem-wide improvements.
Trigger when: (1) User wants to create an educational/explainer video, (2) User has a vague concept they want visualized, (3) User mentions "3b1b style" or "explain like 3Blue1Brown", (4) User wants to plan a Manim video or animation sequence, (5) User asks to "compose" or "plan" a math/science visualization. Transforms vague video ideas into detailed scene-by-scene plans (scenes.md). Conducts research, asks clarifying questions about audience/scope/focus, and outputs comprehensive scene specifications ready for implementation with ManimCE or ManimGL. Use this BEFORE writing any Manim code. This skill plans the video; use manimce-best-practices or manimgl-best-practices for implementation.
Design a PostgreSQL-specific schema. Covers best-practices, data types, indexing, constraints, performance patterns, and advanced features
Optimizes markdown documents for token efficiency, clarity, and LLM consumption. Use when (1) a markdown file needs streamlining for use as LLM context, (2) reducing token count in documentation without losing meaning, (3) converting verbose docs into concise reference material, (4) improving structure and scannability of markdown files, or (5) preparing best-practices or knowledge docs for agent consumption.
