Agent Skills Hub

jest-testing

Provides Jest testing patterns and best practices for interpreters, parsers, and async TypeScript code in the Lea language repository.

n8n-expression-testing

Validate n8n expression syntax, perform context-aware testing, detect common pitfalls, and optimize data transformations within your workflows.

regression-testing

Strategic regression testing with intelligent test selection, impact analysis, and continuous regression management for faster, more reliable software delivery.

http-generate

Automates the generation of .http request files for Spring Boot REST controllers to simplify API documentation and testing.

test-driven-development

Enforces disciplined Test-Driven Development (TDD) by requiring a failing test before implementation, ensuring code reliability and preventing premature over-engineering.

writing-plans

Creates detailed, step-by-step TDD implementation plans for software development tasks.

claude-ralph

vitest-runner

Automated Vitest management skill: handles test execution, coverage reporting, failure diagnosis, and configuration management for TypeScript/JavaScript projects.

always-works-testing

Mandatory execution-based validation for all software implementation tasks. Ensures code works through empirical verification before confirmation.

prompt-injection-test

A testing utility designed to simulate prompt injection attacks and validate security scanners for AI agent skills.

evaluation

Build systematic evaluation frameworks for AI agents using multi-dimensional rubrics, LLM-as-a-judge, and regression testing to measure performance, quality, and context engineering effectiveness.
