AI/ML engineer for LLM integrations, RAG pipelines, vector databases, embeddings, prompt engineering, and AI-powered feature development. Use this skill whenever the user wants to integrate an LLM (OpenAI, Anthropic, Gemini, Ollama, etc.) into their application, build a retrieval-augmented generation (RAG) system, set up a vector database (Pinecone, Weaviate, Chroma, pgvector, etc.), design a prompt, implement semantic search, build an AI agent or tool-use system, fine-tune a model, evaluate AI output quality, or handle AI-specific concerns like hallucination mitigation, cost management, and latency. Also trigger for "how do I add AI to my app", "build me a chatbot that knows about my docs", "help me write a system prompt", or any task involving embeddings, tokens, context windows, or AI pipelines.
Expert system architect for software design, technical specs, and project planning. Use this skill whenever the user asks about system design, architecture decisions, choosing between architectural patterns (microservices vs monolith, event-driven, CQRS, etc.), designing data models, planning technical infrastructure, writing architecture decision records (ADRs), creating technical specs, defining API contracts, or planning a new project from scratch. Also trigger when the user asks "how should I structure this?", "what's the best approach for…", or "help me design a system that…". This is the go-to skill for any high-level technical design question.
Backend engineer for APIs, database design, server-side business logic, and data pipelines. Use this skill whenever the user needs to design or implement a REST or GraphQL API, create or migrate a database schema, write server-side business logic, optimize a slow query, implement background jobs or queues, handle webhooks, design caching strategies, implement rate limiting or pagination, or write data processing pipelines. Also trigger for "build me an endpoint that…", "how should I model this data?", "my queries are slow", "implement this business rule on the server", or any task that's purely server-side without a UI component.
Compliance and data governance expert for privacy regulations, regulatory alignment, and data handling policies. Use this skill whenever the user needs to assess GDPR, CCPA, HIPAA, SOC 2, or other regulatory requirements; implement data subject rights (access, deletion, portability); design a data retention policy; conduct a privacy impact assessment; review data handling practices; write a privacy policy or terms of service; implement audit logging for compliance; handle a data breach response; or understand what compliance obligations apply to their product. Also trigger for "are we GDPR compliant?", "how do I handle a deletion request?", "what do I need for HIPAA?", "we're going through SOC 2 audit", or any question about legal/regulatory obligations around data, privacy, or security.
DevOps engineer for CI/CD pipelines, Docker and containerization, deployment automation, infrastructure-as-code, and monitoring. Use this skill whenever the user needs to set up or improve a CI/CD pipeline (GitHub Actions, GitLab CI, CircleCI, etc.), write Dockerfiles or docker-compose configs, deploy to cloud infrastructure (AWS, GCP, Azure), write Terraform or other IaC, set up monitoring and alerting, configure logging and observability, manage environment variables and secrets in production, automate deployments, set up Kubernetes workloads, or troubleshoot infrastructure issues. Also trigger for "help me deploy this", "set up CI for my project", "write a Dockerfile", "how do I get this to production?", "my deployment is failing", or any infrastructure-related task.
Frontend engineer for UI components, accessibility, responsive design, and client-side logic. Use this skill whenever the user needs to build or improve a UI component, fix a layout or styling issue, implement responsive design, improve accessibility (a11y), manage client-side state, handle forms and validation, implement animations or interactions, optimize frontend performance, or work with a framework like React, Vue, Svelte, Angular, or plain HTML/CSS/JS. Also trigger for "build me a component that…", "this layout looks wrong on mobile", "my form doesn't validate correctly", "make this accessible", "my page is slow to render", or any task that's entirely in the browser/client layer.
Full-stack engineer for cross-cutting implementation, debugging across the entire stack, and building MVPs. Use this skill whenever the user needs to implement a feature that touches both frontend and backend, debug an issue that spans multiple layers (UI → API → database), build a working prototype or MVP quickly, trace a bug through the full request lifecycle, wire together an existing frontend and backend, or when the problem doesn't cleanly belong to just one layer. Also trigger for "make this work end-to-end", "I need a working prototype of…", "something is broken but I don't know where", or any task where changes are needed in multiple parts of the codebase simultaneously.
QA engineer for writing test suites, finding edge cases, and validating software quality. Use this skill whenever the user needs to write unit tests, integration tests, or end-to-end (E2E) tests; audit existing tests for coverage gaps; design a testing strategy; find edge cases in a piece of logic; validate that a feature works correctly; set up a test framework from scratch; or improve test quality (flaky tests, slow tests, poorly structured tests). Also trigger for "write tests for this", "what could go wrong here?", "my tests are flaky", "how should I test this?", "check my test coverage", or when the user has written code and wants to validate it before shipping.
