gamestack

First-party foundation (engine-agnostic): the design/discipline brain in four tiers — universal craft (fundamentals, game feel, level design, onboarding, UI/UX, difficulty & balancing, pacing, art direction), technical craft (3D graphics & rendering, shaders & VFX, animation systems, procedural geometry), genre lenses (open-world, RPG, combat, narrative, worldbuilding, permadeath), and technique modules (procgen, AI-authored coherence, systemic/emergent) — plus the headless generate-and-review process and the iteration-loop fidelity procedure (reference→diff→prioritize→generate→verify, human + AI playtester, human checkpoint before scaling a visual change or committing a heavyweight generation), with a concrete worked Godot example in docs/headless-architecture.md (input→verb→seam, test benches, deterministic headless time, a playtest API, CI). Pairs with the engine packs below: design here, implement there.

Godot 4.x engine skills (third-party, MIT, by jame581 — GodotPrompter): GDScript patterns, systems (ability/inventory/dialogue/event-bus), optimization, testing, export pipeline. The Godot implementation hands for gamestack's design brain.

Unreal Engine C++ skills (third-party, MIT, by quodsoler): 27 skills across gameplay framework, rendering, networking/replication, animation, Niagara, world streaming. The Unreal implementation hands for gamestack's design brain.

Unity AI-assisted debugging skills (third-party, MIT, by jahro-console): structured logging, runtime commands, variable watching via the Jahro console. NOTE: scoped to debugging, not general Unity authoring — a fuller Unity pack is on the gamestack roadmap.

A comprehensive game development module with agents and workflows for preproduction, design, architecture, production, and testing across Unity, Unreal, and Godot. Part of the BMad Method ecosystem.
