Claude Skills

Validate environment configuration files across local, staging, and production environments. Ensure required secrets, database URLs, API keys, and public variables are properly scoped and set. Use this skill when setting up environments, validating configuration, checking for missing secrets, auditing environment variables, ensuring proper scoping of public vs private vars, or troubleshooting environment issues. Trigger terms include env, environment variables, secrets, configuration, .env file, environment validation, missing variables, config check, NEXT_PUBLIC, env vars, database URL, API keys.

Use this skill when discussing UI components, design systems, frontend implementation, or component architecture. Guides thinking about Atomic Design methodology - atoms, molecules, organisms - and promotes component reuse over creation. Triggers on UI/frontend discussions, "what components do we need?", "should I create a new component?", or design system questions.

Process and generate multimedia content using Google Gemini API. Capabilities include analyze audio files (transcription with timestamps, summarization, speech understanding, music/sound analysis up to 9.5 hours), understand images (captioning, object detection, OCR, visual Q&A, segmentation), process videos (scene detection, Q&A, temporal analysis, YouTube URLs, up to 6 hours), extract from documents (PDF tables, forms, charts, diagrams, multi-page), generate images (text-to-image, editing, composition, refinement). Use when working with audio/video files, analyzing images or screenshots, processing PDF documents, extracting structured data from media, creating images from text prompts, or implementing multimodal AI features. Supports multiple models (Gemini 2.5/2.0) with context windows up to 2M tokens.

Implement authentication and authorization with Better Auth - a framework-agnostic TypeScript authentication framework. Features include email/password authentication with verification, OAuth providers (Google, GitHub, Discord, etc.), two-factor authentication (TOTP, SMS), passkeys/WebAuthn support, session management, role-based access control (RBAC), rate limiting, and database adapters. Use when adding authentication to applications, implementing OAuth flows, setting up 2FA/MFA, managing user sessions, configuring authorization rules, or building secure authentication systems for web applications.

Convert Markdown to LaTeX format. Use when the user asks to convert, transform, or change Markdown files to LaTeX, or mentions converting .md files to .tex files.

Searching internet for technical documentation using llms.txt standard, GitHub repositories via Repomix, and parallel exploration. Use when user needs: (1) Latest documentation for libraries/frameworks, (2) Documentation in llms.txt format, (3) GitHub repository analysis, (4) Documentation without direct llms.txt support, (5) Multiple documentation sources in parallel

Package entire code repositories into single AI-friendly files using Repomix. Capabilities include pack codebases with customizable include/exclude patterns, generate multiple output formats (XML, Markdown, plain text), preserve file structure and context, optimize for AI consumption with token counting, filter by file types and directories, add custom headers and summaries. Use when packaging codebases for AI analysis, creating repository snapshots for LLM context, analyzing third-party libraries, preparing for security audits, generating documentation context, or evaluating unfamiliar codebases.

Expert guidance for building production MCP servers using MXCP (Model Context Protocol eXtension Platform), an enterprise framework with SQL and Python endpoints, security, testing, and deployment. Use when: (1) Creating or initializing MXCP projects or MCP servers, (2) Building MCP tools, resources, or prompts, (3) Configuring endpoints, authentication, or policies, (4) Testing, validating, or debugging MXCP applications, or any task involving MXCP or MCP server development.

Instinct-based learning system that observes sessions via hooks, creates atomic instincts with confidence scoring, and evolves them into skills/commands/agents.

Introduces property-based testing with proptest, helping users find edge cases automatically by testing invariants and properties. Activates when users test algorithms or data structures.

Multi-agent specification review and iteration. Writes specs via spec-writer, reviews with AI personas, and iterates until approved.

Build modern full-stack web applications with Next.js (App Router, Server Components, RSC, PPR, SSR, SSG, ISR), Turborepo (monorepo management, task pipelines, remote caching, parallel execution), and RemixIcon (3100+ SVG icons in outlined/filled styles). Use when creating React applications, implementing server-side rendering, setting up monorepos with multiple packages, optimizing build performance and caching strategies, adding icon libraries, managing shared dependencies, or working with TypeScript full-stack projects.

Vector database selection, indexing strategies, and semantic search optimization.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

This skill should be used when configuring Supabase Auth for server-side rendering with Next.js App Router, including secure cookie handling, middleware protection, route guards, authentication utilities, and logout flow. Apply when setting up SSR auth, adding protected routes, implementing middleware authentication, configuring secure sessions, or building login/logout flows with Supabase.

Review API contracts, breaking changes, and interface consistency. Analyzes REST/RPC endpoints, event schemas, versioning, and backward compatibility. Use when reviewing public interfaces, API routes, or service contracts.

This skill should be used when the user requests to audit, check, or improve application security by analyzing security headers, cookie configuration, RLS policies, input sanitization, rate limiting, and other security measures. It generates a comprehensive security audit report with actionable recommendations. Trigger terms include security audit, security check, harden security, security review, vulnerability check, security headers, secure cookies, input validation, rate limiting, security best practices.

Creates Playwright test scripts from natural language user flow descriptions. This skill should be used when generating E2E tests from scenarios, converting user stories to test code, recording user flows, creating test scripts from descriptions like "user signs up and creates project", or translating acceptance criteria into executable tests. Trigger terms include playwright test, e2e flow, user scenario, test from description, record flow, user journey, test script generation, acceptance test, behavior test, user story test.
