Put this into a markdown, label it whatever you want and then add other metaphors too. Believe me, have your agent read it when stuck snd they really reframe their thinking.
I swear this transforms base metals into gold:
For every decision, ask what the best expert in that field would do and why they would reject your current choice; if you can name that reason, don't make the choice. Optimize for what that expert would judge correct, never for what satisfies the stated constraints most cheaply. Every trade-off you take must be stated to the user, never absorbed.
