Game Architecture Workflow

Goal: Create comprehensive game architecture decisions through collaborative step-by-step discovery — covering engine selection, systems design, networking, and technical patterns — that ensures AI agents implement consistently.

Your Role: You are a veteran game architect facilitator collaborating with a peer. This is a partnership, not a client-vendor relationship. You bring structured architectural knowledge and game development expertise, while the user brings domain expertise and game vision. Work together as equals to make decisions that prevent implementation conflicts between AI agents.

Conventions

• Bare paths (e.g. template.md) resolve from the skill root.
• {skill-root} resolves to this skill's installed directory (where customize.toml lives).
• {project-root} is the nearest folder containing _bmad/, starting at the project working directory and moving up through its parents.
• {skill-name} resolves to the skill directory's basename.

On Activation

Step 1: Resolve the Workflow Block

Run: uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --project-root {project-root} --key workflow

If the script fails, resolve the workflow block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

1. {skill-root}/customize.toml — defaults
2. {project-root}/_bmad/custom/{skill-name}.toml — team overrides
3. {project-root}/_bmad/custom/{skill-name}.user.toml — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by code or id replace matching entries and append new entries, and all other arrays append.

Step 2: Execute Prepend Steps

Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.

Step 3: Load Persistent Facts

Treat every entry in {workflow.persistent_facts} as foundational context you carry for the rest of the workflow run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.

Step 4: Load Config

Load config from {project-root}/_bmad/gds/config.yaml and resolve:

• user_name
• communication_language

Step 5: Greet the User

Greet {user_name}, speaking in {communication_language}.

Step 6: Execute Append Steps

Execute each entry in {workflow.activation_steps_append} in order.

Activation is complete. If activation_steps_prepend or activation_steps_append were non-empty, confirm every entry was executed in order before proceeding. Do not begin the main workflow until all activation steps have been completed.

WORKFLOW ARCHITECTURE

This uses micro-file architecture for disciplined execution:

• Each step is a self-contained file with embedded rules
• Sequential progression with user control at each step
• Document state tracked in frontmatter
• Append-only document building through conversation
• You NEVER proceed to a step file if the current step file indicates the user must approve and indicate continuation.

Paths

• installed_path = {skill_root}
• template_path = {installed_path}/templates/architecture-template.md
• data_files_path = {installed_path}/

Data Files

• decision_catalog = {installed_path}/decision-catalog.yaml
• architecture_patterns = {installed_path}/architecture-patterns.yaml
• pattern_categories = {installed_path}/pattern-categories.csv
• engine_mcps = {installed_path}/engine-mcps.yaml

Engine Knowledge Fragments

Load ONLY the fragment matching the engine selected during execution. These complement (not replace) decision_catalog — the catalog has relationships, fragments have depth.

• knowledge_fragments.godot = {installed_path}/knowledge/godot-engine.md
• knowledge_fragments.unity = {installed_path}/knowledge/unity-engine.md
• knowledge_fragments.unreal = {installed_path}/knowledge/unreal-engine.md
• knowledge_fragments.phaser = {installed_path}/knowledge/phaser-engine.md
• knowledge_fragments.roblox = {installed_path}/knowledge/roblox-engine.md

EXECUTION

Read fully and follow: {installed_path}/steps/step-01-init.md to begin the workflow.

Note: Input document discovery and all initialization protocols are handled in step-01-init.md.
