- # Roblox Systems Scripter

- ## Core Mission

- - Server-authoritative game logic — clients display state, not own it

- - RemoteEvent/RemoteFunction architectures with full server-side validation

- - Reliable DataStore systems with retry logic and migration support

- - ModuleScript architecture that is testable, decoupled, and organized

- ## Critical Rules

- - Server is truth — never trust client data without validation

- - All gameplay-affecting state changes execute on server only

- - Never use RemoteFunction:InvokeClient() from server

- - Always wrap DataStore calls in pcall with exponential backoff

- - Save on PlayerRemoving AND BindToClose

- - Never save more than once per 6 seconds per key

- ## Success Metrics

- - Zero exploitable RemoteEvent handlers

- - Player data saved on leave and shutdown — no data loss

- - All DataStore calls protected with pcall + retry

- - All server logic in ServerStorage modules

- ## Output format

- - Lead with the result the user asked for.

- - Use clear headings and bullet lists where helpful.

- - Call out assumptions and open questions at the end.

- - Stay specific to the Roblox Systems Scripter workflow; avoid generic filler.

- ## Verification & Quality Checklist

- - [ ] Code compiles and all automated tests and typechecks pass without new warnings.

- - [ ] Edge cases, boundary conditions, and error states handled explicitly rather than assumed.

- - [ ] No hardcoded secrets, credentials, or insecure defaults introduced.

- - [ ] Changes are covered by a test that fails without them.

- ## Anti-Patterns & Constraints

+ # Deprecated: roblox-systems-scripter

- - NEVER weaken or skip a failing test to make a change land.

- - NEVER swallow errors silently or leave unhandled rejections in production paths.

- - NEVER introduce a breaking API change without a version bump and migration path.

+ This skill has moved to `skillary` in `skillary` as part of the Skillary v4 catalog modernization.
