agent-creator
by mhylle
Create composable AI agent systems in NestJS projects following the "tools all the way down" architecture. Use this skill when users want to: (1) Create new AI agents with orchestrator/planner/executor/evaluator components, (2) Build agentic systems that can call other agents as tools, (3) Implement DAG-based planning with parallel execution, (4) Add database-backed state persistence for agent runs, (5) Create custom evaluators for quality assurance. Triggers on "create agent", "build agent", "agent system", "agentic", "orchestrator", "planner/executor pattern", or NestJS AI agent requests.
security-review
by mhylle
Comprehensive security audit for code changes. Use this skill when implementing authentication, authorization, user input handling, API endpoints, secrets/credentials, payment features, or file uploads. Provides security checklists, vulnerability patterns, and remediation guidance. Integrates with implement-phase as a security quality gate.
continuous-learning
by mhylle
Pattern extraction framework for learning from sessions. This skill captures valuable patterns discovered during work sessions including error resolutions, user corrections, workarounds, debugging techniques, and project-specific patterns. Triggers on Stop hook, end of session, "save learnings", "extract patterns", or when explicitly asked to capture knowledge from the current session. Outputs learned skills to ~/.claude/skills/learned/.
json-canvas
by ZhanlinCui
Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections. Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian.

by dylanfeltus
Generate type scales, color palettes, spacing systems, WCAG contrast checks, and dark mode derivations with math. Use when setting up a design system, creating tokens, or building a Tailwind/CSS theme. Outputs CSS custom properties, Tailwind config, or JSON tokens.
motion-design-patterns
by dylanfeltus
Framer Motion (Motion) animation patterns for React — springs, staggers, layout animations, micro-interactions, scroll effects, and page transitions. Use when building or improving UI animations, adding polish, or making interfaces feel premium.
ant-design
by ant-design
Single-file decision guide for antd 6.x, Ant Design Pro 5/ProComponents, and Ant Design X v2. Use for component selection, theming/tokens, SSR, a11y, performance, routing/access/CRUD, and AI/chat UI patterns.
python-coding-standards
by williamzujkowski
Python coding standards following PEP 8, type hints, testing best practices, and modern Python patterns. Use for Python projects requiring clean, maintainable, production-ready code with comprehensive testing.
filament-pro
by marcelorodrigo
Build Laravel admin panels with Filament v5. Use for creating resources, forms, tables, widgets, and testing admin interfaces with Livewire v4.
reactuse
by siberiacancode
Reactuse delivers production-ready hooks that solve real-world problems. Built with a TypeScript-first approach, SSR compatibility, and tree-shaking optimization for modern React applications.
coding-standards
by williamzujkowski
Comprehensive coding standards and best practices for maintainable, consistent software development across multiple languages and paradigms
react-frontend
by williamzujkowski
React frontend standards covering hooks (useState, useEffect, useContext, custom hooks), state management (Context API, Redux, Zustand), performance optimization (memoization, lazy loading, code splitting), testing with React Testing Library, and accessibility (WCAG 2.1, ARIA) for modern SPAs
hdldiagzero
by lcapossio
Generate clean SVG block diagrams of HDL / RTL top-level designs. Use whenever the user asks to draw, diagram, sketch, render, or visualize an RTL / HDL / FPGA / SoC design — including phrases like "draw the top-level RTL", "diagram of the SoC", "block diagram", "make an SVG of the design", "visualize the architecture". Applies to Verilog, SystemVerilog, VHDL, Vivado BD, and LiteX projects. Color-codes by clock domain, distinguishes AXI-MM / AXI-Lite / AXI-Stream, omits clock/reset/JTAG/debug.
