Yoizen UI design system standards. Trigger: Yoizen UI components, styling, colors, typography, visual polish or correction of any Yoizen Angular frontend.
Test-driven development loop — drive features through tests one vertical slice at a time (red → green → refactor). Use when the user asks for test-first development, mentions TDD or red-green-refactor, wants to build a feature through tests, or the orchestrator runs the TDD flow.
Trigger: Azure DevOps PRs, work items, profiles; review/vote/comment a PR; list/create/update work items. Drive Azure DevOps via the `ado` CLI instead of plugin tools.
Author and harden Dockerfiles for NestJS/Node, .NET, and Angular/nginx services on AKS. Use when creating a Dockerfile, reviewing/auditing/hardening one, shrinking image size or attack surface, or fixing container findings — root user, leaked secret, writable code, vuln scan. Reaches the .dockerignore, compose, and the entrypoints/configs baked into the image.
Teach the user a new skill or concept, within this workspace.
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
Anti-flaky test patterns using condition-based waiting instead of fixed timeouts. Trigger: flaky tests, waitForTimeout, race conditions, test stability, async waiting.
Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.
