Roblox AI Editor Assistant

Self-initiated product case study (not affiliated with Roblox)

Mode-based, project-aware assistant that helps creators learn, fix, and build faster—safely.

Roblox AI Editor — UX Modes — Three focused experiences move users from learning → fixing → generating with the right guardrails.

Context

Role: PM + UX + prototype dev
Timeline: 4 weeks (research → prototype → tests)
Stack: Roblox Studio (Luau), Next.js, Figma

Problem

One-size AI either over-explains for experts or under-explains for beginners, causing context-switching and unsafe code.

Audience

Beginners: syntax + “where does this go?”
Intermediates: patterns & debugging
Pros: scaffolds, refactors, speed
Educators: policy + explainability

Mode Strategy

Explicit, switchable modes reduce prompt-wrestling and align tone + safeguards to intent.

Teach (Beginner)

• Line-by-line explanations with Roblox APIs
• Stepper: Plan → Insert → Explain → Test
• Guardrails on by default

Debug (Intermediate)

• Summarize error logs + stack traces
• Minimal, safe patches with diffs
• One-click rollback + add assertions

Generate (Pro)

• Scaffold modules & patterns, fast
• Permission prompts for risky ops
• Attach tests and run in sandbox

Fix Mode — Error → Patch Diff → Add Test → Apply

Debug Mode ingests stack traces and proposes surgical patches with a diff preview, an explanation, and optional test stubs. Apply with one click and rollback anytime.

• Read error log + current file context
• Generate minimal patch + guardrails
• Attach test and run in sandbox

Fix Mode: Error log and proposed patch diff

Example: pathfinding failure → parameterized repath + guard checks.

Flow: inputs → context → safety policy → task routing → validators → suggestion (diff + risk badge).

Project-Aware Pipeline

Inputs

Current file • Open tabs • Explorer snapshot • Error logs

Outputs

Diff preview • Explanation • Risk badge • Apply | Add test | Run

The assistant uses filenames + open script (no raw code upload by default) and blocks risky APIs. Static checks and sandbox tests raise quality without slowing pros.

Prototype Goals

Beginners’ time-to-first-feature ↓ 36% (26 → 17 min). Compile-without-error on first insert ↑ 85%. Pros rated preset usefulness 4.4/5.
