Implement step definitions for Gherkin scenarios, translating Given/When/Then into executable test code. Use after write-scenario when scenarios are defined but step definitions are missing.

Implement authentication with Scalekit for web applications, APIs, and MCP servers. Supports full-stack auth, modular SSO (SAML/OIDC), and MCP OAuth 2.1. Handles login, SSO, session management, token validation, and enterprise identity providers. Works with Node.js, Express, Next.js, Python, FastAPI, and MCP servers. Use when implementing authentication, adding SSO, securing APIs, or protecting MCP servers.

Run user-defined macOS Shortcuts for custom automation workflows. Use when user wants to trigger a Shortcut by name or execute a custom automation.

Design database models with proper naming, data types, constraints, and relationships. Use this skill when creating or modifying ORM models, database schemas, or entity definitions. When working on files like models.py, models/, entities/, schemas/, or any file defining database tables and their relationships. When adding timestamps, foreign keys, indexes, or validation constraints. When defining model relationships (one-to-many, many-to-many) or cascade behaviors.

Use when translating a program/app idea into a VibeDev MCP Job (deliverables, definition of done, invariants, and a small step plan) and preparing it to transition to READY without implementing features yet

Detect and fix violations of project instructions defined in .claude/rules/. Use when checking code compliance, reviewing changes, or when the user asks about instruction violations.

Ability to analyse, design, optimise, and improve systems that integrate people, processes, technology, and resources to meet defined performance, quality, cost, and safety requirements. Includes applying engineering, statistical, and systems methods to model workflows, identify inefficiencies, evaluate trade-offs, and implement improvements across operations and supply chains. Applies across manufacturing, services, logistics, healthcare, and infrastructure contexts and is independent of specific tools or industries, with human accountability retained for decisions, outcomes, and impacts.

Handle MetaMask signature and transaction popups during Web3 DApp testing - approve signatures, send transactions, call contracts. Detects popup type and handles gas errors.

LLM integration patterns for Claude, GPT, Gemini, and Ollama. Activate for AI API integration, prompt engineering, token management, and multi-model orchestration.

Production-ready scripts for Android app testing, building, and automation. Provides semantic UI navigation, build automation, accessibility testing, and emulator lifecycle management. Optimized for AI agents with minimal token output. Android equivalent of ios-simulator-skill.

Define canonical dotnet format and analyzer verification commands, and provide scripts that generate a format/analyzer report. Use when checking formatting or Roslyn analyzers without reformatting everything.

Creates Better Auth configuration for frontend and backend: handlers, providers, middleware, session/token options. Uses Context7 MCP to retrieve Better Auth docs.

Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.

Templates and automation for initializing and configuring Hardhat projects. Use when setting up new Hardhat projects or adding Hardhat to existing codebases.

Generates a complete iOS app icon set with all required sizes. Use when asked to create an app icon, design an iOS icon, generate app store artwork, or make an icon for an iPhone/iPad app. Follows a philosophy-first approach - first defining the visual identity and concept, then producing production-ready icons.

Use when implementing Bitcoin wallet features - provides complete architecture for on-chain Bitcoin transactions, UTXO management, address derivation from Nostr keys, and transaction handling with proper security patterns

Run a batch of visual comparisons defined in a uiMatch suite JSON file using @uimatch/cli, then read each report to summarize which components passed or failed their quality gates. Use this skill when the user wants to run many Figma-vs-implementation checks at once, such as CI-style validation for a component library or flow.

Generate measurable learning outcomes aligned with Bloom's taxonomy and CEFR proficiency levels for educational content.Use this skill when educators need to define what students will achieve, create learning objectivesfor curriculum planning, or ensure objectives are specific and testable rather than vague.This skill helps break down complex topics into progressively building learning goals with clearassessment methods and success criteria.

Use when navigating code, understanding unfamiliar functions, finding definitions or references, tracing call hierarchies, preparing for refactoring, or analyzing code impact. Enforces LSP-first semantic code intelligence with mandatory pre-edit checks, impact analysis before refactoring, and post-edit diagnostics. Provides IDE-like precision for code operations in large codebases. Covers navigation (goToDefinition, findReferences), understanding (hover, documentSymbol), and call analysis (incomingCalls, outgoingCalls).
