Add official Railway database services (Postgres, Redis, MySQL, MongoDB). Use when user wants to add a database, says "add postgres", "add redis", "add database", "connect to database", or "wire up the database". For other templates (Ghost, Strapi, n8n), use the railway-templates skill.
Comprehensive quantum computing toolkit for building, optimizing, and executing quantum circuits. Use when working with quantum algorithms, simulations, or quantum hardware including (1) Building quantum circuits with gates and measurements, (2) Running quantum algorithms (VQE, QAOA, Grover), (3) Transpiling/optimizing circuits for hardware, (4) Executing on IBM Quantum or other providers, (5) Quantum chemistry and materials science, (6) Quantum machine learning, (7) Visualizing circuits and results, or (8) Any quantum computing development task.
This skill should be used when working with single-cell omics data analysis using scvi-tools, including scRNA-seq, scATAC-seq, CITE-seq, spatial transcriptomics, and other single-cell modalities. Use this skill for probabilistic modeling, batch correction, dimensionality reduction, differential expression, cell type annotation, multimodal integration, and spatial analysis tasks.
Automated hypothesis generation and testing using large language models. Use this skill when generating scientific hypotheses from datasets, combining literature insights with empirical data, testing hypotheses against observational data, or conducting systematic hypothesis exploration for research discovery in domains like deception detection, AI content detection, mental health analysis, or other empirical research tasks.
Use when downloading videos, audio, or captions from YouTube and other video platforms. Supports quality selection.
Integrate external APIs and services with error handling, retry logic, and data transformation. Use when connecting to payment processors, messaging services, analytics platforms, or other third-party providers.
Automate QA regression testing with reusable test skills. Create login flows, dashboard checks, user creation, and other common test scenarios that run consistently.
Add server-side route protection to enforce authentication on specific pages while keeping others public.
Read, modify, execute, and convert Jupyter notebooks programmatically. Use when working with .ipynb files for data science workflows, including editing cells, clearing outputs, or converting to other formats.
Search and contribute to the moltoverflow knowledge base for programming packages. Use when you encounter errors, need solutions for a specific package/language, or want to share knowledge that could help other agents.
A comprehensive skill for creating new ddd4j (Domain-Driven Design for Java) projects based on ddd4j-boot framework. Use ONLY when the user explicitly mentions creating a ddd4j project, initializing ddd4j project, or setting up ddd4j-boot project. Supports three project types: single-module monolith, multi-module monolith, and microservices. Generates project scaffolding based on ddd4j-boot architecture with DDD, Hexagonal Architecture, Clean Architecture, and COLA V5 patterns. Do NOT trigger for generic DDD projects, JPA/Hibernate projects, or other ORM frameworks without explicit ddd4j mention.
AI Hot Topic Collection Tool. Collect AI-related hot content from Twitter/X, Product Hunt, Reddit, Hacker News, blogs and other platforms. Triggered when users say "Start today's topic selection", "Collect hot topics", "See what news is today", "Today's AI hot topics". Focus areas: Vibe Coding, Claude Skill, AI Knowledge Management, AI Model Updates, AI New Products, Overseas Hot Topics.
