Ruby on Rails testing best practices for writing effective, maintainable test suites with RSpec. This skill should be used when writing, reviewing, or refactoring Rails tests to ensure proper test design, data management, and coverage patterns. Triggers on tasks involving RSpec specs, model tests, request specs, system tests, factory definitions, Capybara interactions, Sidekiq job tests, or test suite optimization. Complementary to rails-dev, ruby-optimise, and ruby-refactor skills.
Guide for using Docker - a containerization platform for building, running, and deploying applications in isolated containers. Use when containerizing applications, creating Dockerfiles, working with Docker Compose, managing images/containers, configuring networking and storage, optimizing builds, deploying to production, or implementing CI/CD pipelines with Docker.
Use when choosing a testing strategy, right-sizing test coverage, or understanding test categories. Covers the Test Trophy model, test type tradeoffs, and guidance on balancing static analysis, unit, integration, and end-to-end tests. USE FOR: testing strategy, Test Trophy, test type selection, right-sizing test coverage, balancing test categories, choosing testing tools, test automation architecture DO NOT USE FOR: specific test category implementation (use static-analysis, unit-testing, integration-testing, e2e-testing, etc.), BDD specification authoring (use specs/documentation/gherkin)
Generate a README introduction following the Diataxis 4-paragraph structure for product documentation.
Generate a Phase Spec/PRD by extracting features from an annotated Vision PRD. Use when user wants to create quarterly phase documentation, extract requirements from vision, plan a development phase, or decompose features into R-nnnn requirements. Requires annotated Vision PRD with F-nnn tags and Coverage Index.
Use for web apps that need Leaflet-first GIS mapping, location selection, map-driven UIs, or geofencing validation. Covers Leaflet setup, optional tile providers, data storage, and backend validation patterns.
Build strategic plans for business goals. Creates one-page briefs with core objective, key milestones, leverage points, and risks. Use when setting direction, pitching initiatives, or aligning teams around a goal.
