Roblox Diagnosis
Finding the cause of a reported symptom. Nothing here writes the fix and nothing here scores a codebase — this skill decides what is actually wrong and hands that answer on.
It exists because a bug report names a symptom, never a file. Reaching for the first plausible file and editing it produces a change that looks like a fix, passes review, and leaves the defect in place.
Goal, in priority order: cause → evidence → cheapest probe → clean handoff. A confirmed cause with narrow evidence beats a broad theory. Guessing costs more than asking.
This skill ships as part of a set and does not stand alone. Every reference it cites lives in
../best-practices/references/, the pool shared by all four roblox-optimum skills. Installing this directory on its own leaves those links pointing at nothing. If a reference will not open, the install is incomplete — say so rather than diagnosing from memory.
