roblox-debug

When to Load

Load when diagnosing errors, crashes, or unexpected behavior in Roblox/Luau code. Provides a structured 7-step iterative debug loop with a max of 5 iterations before escalating. Works in both file-sync and MCP modes.

Quick Reference

7-Step Debug Loop (max 5 iterations)

1. Error Gathering — Get exact error message, stack trace (script + line), trigger condition (join/action/timer). Use MCP for console output if available.

2. Code Discovery — Read relevant script(s). Search for error text, function names, or script from stack trace.

3. Root Cause Analysis — Categorize: Syntax (missing end) · Runtime (nil, destroyed Instance) · Logic (wrong calc/condition) · Security (client-side logic) · Performance (timeout, memory). Load roblox-sharp-edges for known gotchas. Find the exact line + true root cause.

4. Generate Fix — Produce corrected Luau. Explain what was wrong, why fix works, related code to check. Flag architectural changes.

5. Apply & Test — Write fix to file. MCP verify if available. In offline mode: before/after diff + manual test instructions.

6. Verify — Resolved → Step 7. New errors → back to Step 1. Same error → new hypothesis, back to Step 3. Iteration 5 → escalate with full diagnosis.
