Rapid prototyping workflow for Unity. Quickly validates a mechanic or concept with throwaway code and a structured report.

Load a saved plan from ProjectSettings/GameDeck/plans/ and execute it step-by-step.

Save a plan to ProjectSettings/GameDeck/plans/ — captures the most recent plan from this conversation, or a plan you provide directly.

Plan a feature implementation with tasks, architecture, and file list.

Generate a complete Unity system — MonoBehaviour + ScriptableObject config from structured input.

Analyze and refactor a file or system with before/after comparison.

Creates an Architecture Decision Record (ADR) documenting a technical decision, alternatives, and consequences.

Audits Unity assets for naming conventions, file size budgets, format standards, and orphaned/missing references.

Analyzes game balance data (ScriptableObjects, configs) for outliers, broken progressions, and degenerate strategies.

Guided game concept ideation — generates ideas for gameplay mechanics, systems, or features using structured creative techniques.

Creates structured bug reports or analyzes code to identify potential bugs. Ensures full reproduction steps and severity assessment.

Auto-generates changelog from git commits and task completion status.

Performs architectural and quality code review on Unity C# files. Checks coding standards, SOLID, Unity best practices, and performance.

Create a new custom slash command — generates a SKILL.md template and saves it to ProjectSettings/GameDeck/commands/.

Reviews a game design document for completeness, consistency, implementability, and balance. Run before implementation.

Estimates task effort by analyzing complexity, dependencies, and risk. Produces structured estimates with confidence levels.

Emergency fix workflow with audit trail. For S1/S2 bugs that need immediate resolution.

Decomposes a game concept into individual systems, maps dependencies, and prioritizes design/implementation order.

Structured performance profiling workflow for Unity. Identifies bottlenecks, measures against budgets, and recommends optimizations.

Generates structured playtest report template or analyzes playtest notes into actionable format.

Generates design or architecture documentation from existing code. Works backwards from implementation to create missing docs.

Analyzes a feature or phase for scope creep. Compares current scope against the original plan in TASKS.md.

Generates or updates a sprint plan based on docs/TASKS.md backlog, completed work, and priorities.

Scans codebase for technical debt indicators (TODO, FIXME, HACK, complexity), tracks and prioritizes debt items.
