Turn ambiguity into explicit choices
Words such as 'clean up', 'optimize', or 'professional' can mean different things to different people. Add a concrete example, target audience, or acceptance rule so the agent can distinguish required changes from optional polish.
If a choice depends on your preference, say whether the agent should ask, use a stated default, or present alternatives. This is especially useful when changing navigation, public copy, data formats, or other decisions that are costly to reverse.
Review assumptions before impact
For low-impact reversible work, a reasonable default may keep progress moving. For deletion, publication, permission changes, or external communication, require the intended target and effect to be clear first.
At completion, compare the result with the original outcome and check any assumptions the agent disclosed. If the result missed the mark, clarify the specific decision and continue from the current work instead of restarting without context.
