Comprehensive NestJS framework skill for building scalable server-side applications. Use for TypeScript backend development with controllers, providers, modules, dependency injection, middleware, guards, interceptors, pipes, database integration (MikroORM + MongoDB), GraphQL, microservices, testing, and API documentation. Also triggers when working with NestJS TypeScript files (.ts), NestJS module files, nest-cli.json, or NestJS project structure. Example triggers: "Create NestJS controller", "Set up dependency injection", "Add middleware", "Create GraphQL resolver", "Build microservice", "Write NestJS test", "Set up database module"

Write and update RSpec tests following BDD principles with behavior-first approach, characteristic-based context hierarchy, and happy path priority. **Activate when:** user mentions RSpec/specs/testing, works with *_spec.rb files, asks to write/add/update/fix tests, or requests test coverage. Ensures tests describe observable behavior, not implementation details.

Expert on testing Move smart contracts on Aptos, including unit tests, integration tests, Move Prover formal verification, debugging strategies, and test coverage. Triggers on keywords move test, unit test, integration test, move prover, formal verification, debug, coverage, assert, expect

Generate, explain, and test regular expressions with examples and test cases. Use when creating regex patterns or understanding complex regular expressions.

CI/CD pipeline configuration for monorepo testing including GitHub Actions workflows, Turborepo integration, two-tier quality gates (typecheck→lint→test→build), preview branch integration, retry logic, and environment management. Use when configuring CI pipelines, troubleshooting CI test failures, implementing preview deployments, or optimizing CI performance. Triggers on: CI configuration, github actions testing, CI pipeline, turborepo CI, quality gates, preview integration, CI troubleshooting.

A minimal test skill that demonstrates the basic skill structure

Design, analyze, and evaluate philosophical thought experiments. Use when: creating new thought experiments to probe specific intuitions, analyzing existing thought experiments for hidden assumptions, generating variants that isolate different variables, stress-testing philosophical positions through scenarios, exploring edge cases. Triggers: 'thought experiment', 'imagine', 'suppose', 'hypothetical', 'what if scenario', 'intuition pump', 'trolley problem', 'zombie', 'Mary's room', 'Chinese room', 'experience machine', 'teletransportation', 'original position', 'veil of ignorance', 'Gettier case'.

This skill should be used when the user asks to "create a decorator", "write a decorator", "add presentation logic", "format model data for views", "use Draper", "test a decorator", "write decorator spec", or mentions separating presentation from business logic in Rails. Provides guidance on Draper gem best practices for Rails applications.

Mandatory best practices and gold standards for Kailash SDK development including absolute imports, parameter passing, error handling, testing policies (NO MOCKING in Tiers 2-3), workflow design, custom node development, security, documentation, and test creation. Use when asking about 'best practices', 'standards', 'gold standards', 'mandatory rules', 'required patterns', 'absolute imports', 'NO MOCKING', 'testing policy', 'error handling standards', 'security best practices', 'documentation standards', or 'workflow design standards'.
