Building Mechanics Router

Building Mechanics Router

Routes to 9 specialized skills based on game requirements.

Routing Protocol

1. Classify — Single/​multiplayer + scale + core features
2. Match — Apply signal matching rules below
3. Combine — Most games need 3-5 skills together
4. Load — Read matched SKILL.md files before implementation

Quick Route

Tier 1: Core Mechanics

Tier 2: Enhanced Features

Tier 3: Platform & Reference

Signal Priority

When multiple signals present:

1. Multiplayer explicit → multiplayer-building required
2. Scale indicator → >1000 pieces triggers performance-at-scale
3. Persistence → Long-running servers trigger decay-upkeep
4. Platform constraint → Mobile/​VR triggers platform-building
5. Default → structural-physics always relevant for building games

Common Combinations

Full Survival (Rust-style, 6 skills)

performance-at-scale → spatial indexing
structural-physics → stability + damage
multiplayer-building → networking
terrain-integration → foundations on slopes
decay-upkeep → Tool Cupboard + upkeep
builder-ux → blueprints + undo

Battle Royale Building (2 skills)

performance-at-scale → fast collision
multiplayer-building → low-latency sync

Single-Player Builder (3-4 skills)

structural-physics → stability + damage
terrain-integration → natural terrain
builder-ux → blueprints + undo
performance-at-scale → if >1000 pieces

Persistent Server (4 skills)

multiplayer-building → networking
structural-physics → stability
decay-upkeep → automatic cleanup
performance-at-scale → entity management

Decision Table

Integration Order

When combining skills, wire in this sequence:

1. Spatial index → Query foundation for all other systems
2. Validator → Uses spatial for neighbor/​support detection
3. Damage → Uses spatial for cascade radius
4. Network → Broadcasts all state changes
5. Client prediction → Uses local spatial + validator

Fallback

• No scale stated → Ask: "How many pieces expected?"
• Unclear mode → Ask: "Single-player or multiplayer?"
• Generic "building game" → Start with structural-physics + builder-ux
