How to Test One AI-Generated Game Change Before Moving to the Next Prompt
Use a micro-regression loop: record the expected behavior, apply one change, run the target scenario and two or three neighboring checks, then commit or revert before asking for the next feature.

One prompt should end in a decision
After an AI change, the decision is accept, revise, or revert. If you immediately issue another prompt without testing, you lose the ability to attribute the next failure to a specific change.
Use a tiny repeatable test set
The target check proves the new behavior. Neighbor checks cover systems sharing state or inputs. For a weapon reload change, neighbors might be firing, weapon swap, and ammo persistence—not the entire game.
Record the result in the project state
A short commit message or ledger entry should state what changed and what passed. This gives the next agent a verified base instead of an assumption that the previous prompt worked.
Revert faster than you repair unclear changes
If the patch creates failures you cannot explain and the change is small, reverting is often cheaper than asking the model to stack fixes. Keep forward-fix work for cases where the cause is understood and the new architecture is intentional.
Working template
PROMPT CHANGE: [...] TARGET TEST: [...] NEIGHBOR CHECK 1: [...] NEIGHBOR CHECK 2: [...] RESULT: accept / revise / revert ONLY AFTER ACCEPT: start the next prompt.
