Writing your standards as if a new colleague had to follow them without asking is the most useful advice here, and it applies whether the reader is a person or an agent. I'd add one thing to that page: examples of what you rejected, next to the rules. "Warm, not generic" means different things to different people, but three images you turned down, with a line on why, leave much less room for guessing. The point about saved standards repeating a weak decision is worth repeating too. A Skill or a locked Style just makes whatever you saved consistent. If the rule was vague, you get consistent vagueness, which is harder to spot than the drift you started with.
