Comprehensive Convex development skill for implementing backend features with Zod validation, custom function wrappers, and convex-helpers utilities.

Spring Boot 4 observability with Actuator, Micrometer, and OpenTelemetry. Use when configuring health indicators, custom metrics, distributed tracing, production endpoint exposure, or Kubernetes/Cloud Run probes. Covers Actuator security, Micrometer Timer/Counter/Gauge patterns, and OpenTelemetry span customization.

Design and implement NestJS REST API endpoints following the project's layered architecture (Controllers, Use Cases, Repositories). Use this skill when creating or modifying controller files (*.controller.ts), defining API routes, implementing HTTP handlers, setting up Swagger documentation, configuring route guards and decorators, working with request/response DTOs, or structuring API endpoints. This includes files in features/{feature}/controller/, auth/controller/, and any file with @Controller() decorator. Apply when working with API_ENDPOINTS constants, @Get/@Post/@Put/@Patch/@Delete decorators, @ApiTags/@ApiProperty swagger decorators, @Public/@MemberRoles custom decorators, HttpCode/HttpStatus configurations, or Query/Param/Body parameter decorators.

Provides NestJS framework development standards and architectural patterns. Ensures domain-centric architecture, proper dependency injection, and decorator pattern utilization. Specializes in modular design, providers and services, middleware and guards, interceptors and pipes, custom decorators, and microservices architecture.Use when: developing NestJS applications, designing module structure (@Module), creating controllers (@Controller) and services (@Injectable), implementing REST or GraphQL APIs, configuring dependency injection, building middleware and guards, creating custom decorators, implementing authentication/authorization, designing microservices with NestJS, or integrating with TypeORM/Prisma for database access.

Build AI chat interfaces with custom backends, authentication, and context injection. Use when integrating chat UI with AI agents, adding auth to chat, injecting user/page context, or implementing httpOnly cookie proxies. Covers ChatKitServer, useChatKit, and MCP auth patterns. NOT when building simple chatbots without persistence or custom agent integration.

Run code quality checks for Laravel Spectrum (PHPStan, Laravel Pint, PHPUnit). Use when user mentions "lint", "format", "code quality", "PR準備", "コミット前チェック", or before creating commits/PRs. Also use after writing significant code changes.

Analyze Ruby and Rails code quality with RubyCritic. Identifies code smells, complexity issues, and refactoring opportunities. Provides detailed metrics, scores files A-F, compares branches, and prioritizes high-churn problem areas. Use when analyzing Ruby code quality, reviewing PRs, or identifying technical debt.

Convert between data formats (JSON, CSV, XML, YAML, TOML). Handles nested structures, arrays, and preserves data types where possible.

Web scraping spiders (Scrapy), parsers, and source management.

Archive immutable audit trails for accountability.

Transform question-lists and disconnected fragments into flowing methodology where each sentence earns its place by capturing relationships that isolated pieces cannot convey. Use when: (1) a skill contains "consider whether..." prompts that remain unintegrated, (2) related ideas are expressed as separate bullets rather than connected prose, (3) the skill reads as a checklist rather than an explanation of a way of thinking.

Production-grade Flutter accessibility mastery - Semantics API, screen readers (VoiceOver/TalkBack), WCAG 2.1 AA/AAA compliance, inclusive design patterns, automated a11y testing with comprehensive code examples

[Aesthetics] Defines temporal aesthetics: speed, acceleration habits, tempo, static vs dynamic balance, motion weight and inertia. Produces Motion Bible as Memo nodes in Brain canvas.

Kotlin/Spring Boot 3.x patterns - use for backend services, REST APIs, dependency injection, controllers, and service layers

n8n workflow automation patterns and API integration. This skill should be used when creating n8n workflows, using webhooks, managing workflows via REST API, or integrating n8n with MCP servers. Covers workflow JSON structure, node patterns, and automation best practices.

This skill should be used when the user asks to "implement dynamic forms", "formily complex forms", "formily conditional fields", "formily nested forms", "formily async validation", "formily performance optimization", or "advanced formily patterns".

Expert guidance for Fastify web framework including server setup, routing, plugins, hooks, validation, error handling, and TypeScript integration. Use this when building high-performance Node.js web servers and REST APIs.

Build enterprise-grade Node.js applications with NestJS framework, TypeScript, dependency injection, and modular architecture

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK). | Sử dụng khi: tạo MCP server, xây dựng tool server.

[Aesthetics] Extracts recurring visual patterns from references: contrast habits, shapes, density/whitespace balance, rhythm, textures. Produces Aesthetic Pattern Library as Data-Sheet nodes in Brain canvas.
