Two Rulers: How Big the Cost, Whether You Can Undo
To decide between letting go and adding a checkpoint, don't go by gut—measure with two rulers:
Ruler one · cost of a mistake: if this step goes wrong, how big is the loss?
Ruler two · reversibility: after it goes wrong, can you easily undo it?
Four Quadrants: How to Decide with These Two Rulers
Cross the two rulers and you get four cases:
Low cost + reversible (e.g. reading files, editing a local draft) → safely go fully automatic.
High cost + irreversible (e.g. dropping a database, pushing to production, mass email) → require a human checkpoint.
The two in between (high cost but reversible / low cost but irreversible) → it depends, lean toward confirming first.
Put Checkpoints Where They Count
More human checkpoints isn't better—too many degrades into cautious-everywhere, slow and annoying. The smart move is to only gate the key actions.
That way you enjoy the speed of automation while holding the line at the truly dangerous steps—that's a well-tuned AI terminal.

Which two "rulers" does the lesson suggest using to decide between letting go and adding a checkpoint?
答案:Cost of a mistake + reversibility
The two rulers are: how big the loss if wrong (cost of a mistake) and whether you can undo it (reversibility).
Fill in: the combination to fear most and most needing a human checkpoint is "big cost + ____."
答案:irreversible
An action with big cost that also can't be undone is the highest risk and must have human confirmation.
"Editing a few lines in a local draft file, easily reverted if wrong"—which category, and how to handle it?
答案:Low cost + reversible, can safely be fully automatic
Editing a local draft is low loss and easy to undo—a low-risk action you can let go fully automatic.
"Letting the AI push changes directly to the live production environment"—how should this be handled?
答案:Add a human checkpoint, confirm before executing
Pushing to production is high-cost and irreversible—exactly the key action that should have a human checkpoint and confirmation.
Judge: the more human checkpoints the better—ideally have a person confirm every single step.
答案:Incorrect
Too many checkpoints degrades into cautious-everywhere, slow and annoying; gate only before irreversible, high-cost key actions.
Judge: putting the human confirmation in front of actions that are "irreversible and high-loss if wrong" is putting the checkpoint where it counts.
答案:Correct
Confirming before high-cost, irreversible actions holds the line while not sacrificing the automation speed of the rest.
