About roblox-architecture
A Roblox architecture skill for planning ownership, module boundaries, integration, and startup. It guides developers toward explicit authority and lifecycle rules, with structures sized to the evidence and runtime boundaries.
Key features
- 01Defining state ownership and callers
- 02Setting module and runtime boundaries
- 03Keeping dependencies small
- 04Making startup sequencing explicit
- 05Reviewing authority and cleanup
Use cases
- 01Planning ownership for a behavior
- 02Deciding where server and client code split
- 03Designing ordered module startup
- 04Evaluating whether an ECS is justified

When to Load
Load for ownership, integration, boundaries, startup, or module splits.
Quick Reference
Reuse proven project modules before rebuilding; inspect contracts and failure/cleanup paths. Integration workflow: full.md.
Start from one owner
For each behavior, name:
- authoritative state and who may mutate it;
- public operations and callers;
- Roblox instances, connections, and tasks it owns;
- persistence or network boundary;
- startup and teardown conditions.
Group by feature when that keeps one change together. Split server, client, and shared code only where the runtime boundary requires it. Shared code has no secrets or authoritative mutable state.
Use the smallest dependency shape
Direct module calls are the default. Use a signal only when one publisher has genuinely independent observers. Do not add an event bus, dependency container, manager class, or Init/Start ceremony to hide an ordinary dependency.
Keep module top-level work cheap and non-yielding. A small bootstrap owns startup that needs ordering; call it sequentially and fail visibly. Concurrency must be explicit and safe, not automatic task.spawn everywhere.
Bound WaitForChild when a dependency arrives through replication; an unbounded wait turns a missing instance into a silent hang.
Enforce runtime authority
The client presents and predicts; the server validates and decides. Remotes are APIs with types, bounds, ownership, abuse controls, and failure behavior. Route details to roblox-networking and roblox-security.
Split only for evidence
Split when there is a separate lifecycle or authority boundary, a distinct persistence contract, an independently testable pure core, or unrelated reasons to change.
Data-oriented alternative: only on evidence
An ECS earns its cost only when many similar entities update every frame by order-independent logic, or cross-cutting queries replace tangled per-entity scripts; hooks enforce invariants, ordered systems decide. Version-specific pitfalls: full.md "ECS on Roblox".
Review
One canonical owner per mutation, no hidden startup yield or replicated trust decision, explicit cleanup, smallest traceable structure. Tags are discovery, attributes configuration, one owner for attach/remove cleanup.
