Guide developers through property-based testing including property definition, shrinking, and framework-specific implementation

Guide for implementing features in ClaudeBar following architecture-first design, TDD, rich domain models, and Swift 6.2 patterns. Use this skill when:(1) Adding new functionality to the app(2) Creating domain models that follow user's mental model(3) Building SwiftUI views that consume domain models directly(4) User asks "how do I implement X" or "add feature Y"(5) Implementing any feature that spans Domain, Infrastructure, and App layers

Generate production-quality TypeScript CLIs with full documentation, error handling, and best practices.Creates deterministic, type-safe command-line tools following CLI-First Architecture.USE WHEN user says "create a CLI", "build a command-line tool", "make a CLI for X", or requests CLI generation.

Jest unit testing standards covering configuration, test structure, testing patterns, and coverage requirements

Implement or extend a user-facing workflow in a web application, integrating with existing backend APIs. Use when the feature is primarily a UI/UX change backed by existing APIs, affects only the web frontend, and requires following design system, routing, and testing conventions.

Enforces project documentation structure in docs/plans/ directories - research.md for facts, design.md for decisions, tasks.md for implementation, thoughts/ for explorations.

Run credibility checks on feature interpretations including split-half stability and shuffle null tests

Building database queries with the Options API

Orchestrate end-to-end feature development from requirements through implementation, testing, and review. Use when: (1) planning feature development stages, (2) coordinating multi-agent feature workflows, (3) understanding SDLC phases for new features.

Generates a rigorous experiment design given a hypothesis. Use when asked to design experiments, plan experiments, create an experimental setup, or figure out how to test a research hypothesis. Covers controls, baselines, ablations, metrics, statistical tests, and compute estimates.

Comprehensive skill for writing high-converting, AI-optimised website copy that combines Generative Engine Optimization (GEO) with strategic copywriting psychology. Use when: (1) Writing new website copy, landing pages, or marketing content, (2) Performing SEO audits or content reviews, (3) Optimising content for AI Answer Engines (Google AI, Perplexity, ChatGPT), (4) Implementing Schema markup (JSON-LD structured data), (5) Writing B2B or B2C-specific copy, (6) Creating About Us pages or brand storytelling content, (7) Writing microcopy, error messages, or UX text, (8) Ensuring accessibility and inclusive language.Invoke with: /write-website-copy, /audit-seo, /generate-schema, /validate-content, or say "use the website-copy-standards skill to..."

Commitlint configuration and GitHub Copilot commit message instruction templates with validation logic for conventional commit enforcement. Includes 6 required standards (conventional format, relaxed subject rules for Copilot compatibility, optional scope, Husky integration, required dependencies, Copilot instruction consistency).

Implements Firebase Authentication with email, OAuth, phone auth, and custom tokens. Use when building apps with Firebase, needing flexible auth methods, or integrating with Firebase ecosystem.

Build AI agents using prompt-native architecture where features are defined in prompts, not code. Use when creating autonomous agents, designing MCP servers, implementing self-modifying systems, or adopting the "trust the agent's intelligence" philosophy.

Master Kotlin syntax, OOP principles, SOLID practices, functional programming, and data structures. Use when writing Kotlin code or designing class hierarchies.

Automate creation of complete CRUD entities (backend Laravel + frontend Vue) following Budget Manager project conventions. Use when the user asks to create a new entity, model, resource, or CRUD feature. Triggers on requests like "create a new category entity", "add a product model with CRUD", "generate an entity for transactions", or any request to scaffold a complete feature with database, API, and UI components.
