Next.js environment variable management with file precedence, variable types, and deployment configurations. Use when configuring Next.js applications, managing environment-specific settings, or deploying to Vercel/Railway/Heroku.

Manage digital product sales across Gumroad, Etsy, Shopify. Handle sales tracking, product delivery, and social media automation.

Automatically choose the best tech stack based on requirements. User never sees this.Use when: starting a new project after idea validation.Triggers: internal use only, called by build pipeline.

Create Mermaid diagrams (activity, deployment, sequence, architecture) from text descriptions or source code. Use when asked to "create a diagram", "generate mermaid", "document architecture", "code to diagram", "create design doc", or "convert code to diagram". Supports hierarchical on-demand guide loading, Unicode semantic symbols, and Python utilities for diagram extraction and image conversion.

Write strategic, behavior-focused tests for critical paths without over-testing during development. Use this skill when writing unit tests, integration tests, or end-to-end tests. When working on files in tests/, __tests__/, spec/, or any test files. When deciding what to test, naming test cases, or mocking external dependencies. When focusing on core user flows rather than edge cases during feature development.

Validate HTML5 structure and basic syntax. BLOCKING quality gate - stops pipeline if validation fails. Ensures deterministic output quality.

Master-level fullstack software engineering with deep backend expertise. Use when building production-grade APIs, database architectures, authentication systems, microservices, or any backend-heavy application. Triggers on: (1) API design and implementation, (2) Database schema design and optimization, (3) Authentication/authorization systems, (4) System architecture decisions, (5) Performance optimization, (6) Error handling and logging, (7) Testing strategies, (8) DevOps and deployment, (9) Security hardening.

Draft detailed engineering specs from an approved PRD. Use when generating or updating the engineering specification for a feature, before implementation begins.

End-to-end testing for Blazor applications using Playwright for .NET. Use when writing E2E tests, creating test infrastructure, testing MudBlazor components, handling Blazor WebAssembly loading, debugging test failures, or setting up CI/CD test pipelines.

Use when unsure about command syntax, options, or behavior, or when the user asks to "check the man page", "look up the manual", or "what does [command] do". Consult system man pages for accurate, version-specific documentation.

Structured investigation with a persistent markdown log and evidence-first execution. Use when: investigating a user question, auditing behavior, verifying dependencies, or using MCP tools. Triggers: inspect, investigate, analyze, audit, verify, deepwiki. Default mode: MANIFEST_IO.

Resize a Canva design into multiple social media formats (Facebook post, Facebook story, Instagram post, Instagram story, LinkedIn post) and export all versions as PNGs. Use this skill when users want to resize Canva designs specifically for multiple social media platforms in one operation, rather than resizing to a single format manually.

Master programming fundamentals, algorithms, data structures, and multiple languages. Covers Python, Java, Go, Rust, C++, Kotlin, Bash, and computer science essentials for every developer.

Performs intelligent compliance audits for software projects. Automatically detects which regulatory frameworks (GDPR, HIPAA, PCI-DSS, CCPA, SOC 2) apply based on project analysis and user context. Provides tiered reports with executive summaries and detailed technical findings. Use when the user asks about compliance, regulatory requirements, security standards, data protection, or wants to audit their codebase for legal/regulatory adherence.

Expert prompt engineering for LLMs and AI agents. Use when users request help writing, reviewing, or improving prompts for chatbots, AI agents, system prompts, instruction sets, or any LLM-based application. Applies research-backed techniques to minimize hallucinations and maximize reliability.
