Pre-built and custom Clerk authentication component templates with theming and customization patterns. Use when building authentication UI, creating sign-in/sign-up pages, customizing Clerk components, implementing user buttons, theming auth flows, or when user mentions Clerk components, SignIn, SignUp, UserButton, auth UI, appearance customization, or authentication theming.

Static analysis, code quality checks, and security scanning agent

Creates Claude Code skills where each skill is tied to a specialist agent optimized with evidence-based prompting techniques. Use this skill when users need to create reusable skills that leverage specialized agents for consistent high-quality performance. The skill ensures that each created skill spawns an appropriately crafted agent that communicates effectively with the parent Claude Code instance using best practices.

This skill should be used when seeding databases with realistic fake data for development, testing, or staging environments. Supports PostgreSQL, MySQL, SQLite, MongoDB with ORM-based seeding (SQLAlchemy, Django, Prisma) and Faker library for generating realistic test data. Use when the user needs to populate databases with sample data, create test fixtures, or set up development/staging environments with realistic data.

Scans new/modified code against multi-mono shared libraries (@metasaver/core-utils, @metasaver/core-service-utils, @metasaver/core-components) to detect DRY violations. Use when auditing code for duplicate functions, types, or components that already exist in shared packages. Returns violation reports with suggested import replacements.

Create GitHub issues with duplicate detection and codebase analysis. Use when you discover a bug, improvement, or issue that wasn't in the original scope/spec during development. Triggers on phrases like "create an issue", "file a bug", "this should be tracked", "we should fix this later", "out of scope issue", "noticed a problem", "found a bug".

Expert guidance for n8n workflow automation using REST API and CLI. Use when creating, updating, debugging, or managing n8n workflows. Provides efficient alternatives to MCP server with direct API calls and scripts. Covers workflow patterns, node configuration, API endpoints, CLI commands, and debugging strategies.

Manage portal content including saving WebMaps/WebScenes, bookmarks, slides, and portal items. Use for content persistence, WebMap/WebScene configuration, and navigation presets.

Validates code against Semicolon Team Codex rules including commit conventions, code quality standards, and development best practices. Use before commits and during code reviews.

Scan code for security vulnerabilities. Use after implementation changes.

Check TypeScript compilation errors, run build commands, and validate the codebase. Use when the user mentions TypeScript errors, build issues, compilation problems, or wants to verify code integrity.

Autonomous web research for presentation topics using Claude Agent SDK. Conducts multi-step research, extracts insights, and manages citations.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Comprehensive Supabase development expert covering Edge Functions, database schema management, migrations, PostgreSQL functions, and RLS policies. Use for any Supabase development including TypeScript/Deno Edge Functions, declarative schema management, SQL formatting, migration creation, database function authoring with SECURITY INVOKER, and RLS policy implementation with auth.uid() and auth.jwt().

Comprehensive feature development workflow management with branching strategies, code reviews, testing automation, and deployment coordination.

General software development practices including code review, testing strategies, and CI/CD integration. Use when implementing features, writing tests, setting up deployment pipelines, or conducting peer reviews.

Load when user says "mental model", "think through this", "structured thinking", "help me decide", "analyze this problem", "first principles", "pre-mortem", "stakeholder mapping", "what framework should I use", or any specific model name. Provides 59 thinking frameworks for decision-making, problem decomposition, and strategic analysis.
