Design or improve onboarding flows, empty states, and first-time user experiences. Helps users get started successfully and understand value quickly.

Implement draft/published workflow versioning: publish, rollback, version pinning for runs, and safe migrations. Use when changing version storage, publish/rollback flows, or run version pinning.

Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible

Use for architecture, refactors, or new gameplay systems in this Godot 4.6 survivor project. Enforces data-driven design, composition over inheritance, and separation between gameplay systems, resources, and UI.

Enforces clean code decomposition following Uncle Bob's Clean Code principles and SOLID. Apply whenever writing functions, classes, or modules in any Kotlin/JVM project.

Fully autonomous TDD with strict guardrails. Use when you want the AI to drive the entire RED-GREEN-REFACTOR cycle independently while maintaining TDD discipline.

Create a detailed refactor plan with tiny commits via user interview, then file it as a Jira ticket. Use when planning a refactor, creating a refactoring RFC, or breaking a refactor into safe incremental steps.

Executes a multi-stage refactoring plan based on existing `audit.md` and `improvements.md` files. Reads the recommendations, scans the target source code, and builds an implementation roadmap before applying atomic code transformations.

This skill systematically applies code improvements based on analysis, ensuring quality, maintainability, and correctness through iterative changes and comprehensive verification.

Profile, identify bottlenecks, optimize, measure, and validate improvements

Database design, migrations, queries, and data integrity best practices

Svelte runes guidance. Use for reactive state, props, effects, attachments, or migration. Covers $state, $derived, $effect, @attach. Prevents reactivity mistakes.

Analyze GitHub repositories and explain their structure

Database migration best practices for schema changes, data migrations, rollbacks, and zero-downtime deployments across PostgreSQL, MySQL, and common ORMs (Prisma, Drizzle, Django, TypeORM, golang-migrate).
