Why does atomic workflow steps fail?

The right granularity is the level at which a step can be completed without ambiguity but also without condescension — where each step represents a single meaningful action that could independently succeed or fail. The failure mode is not insufficient decomposition. It is decomposition that generates more cognitive load than it eliminates.

The fix: Take one recurring workflow from your life — morning routine, weekly review, project kickoff, content publishing, anything you do repeatedly. Write out every step as you currently understand it. Then, for each step, apply the ambiguity test: if you handed this step to a competent stranger with no additional context, could they complete it without asking a single clarifying question? Any step that fails this test is not yet atomic. Decompose it until every sub-step passes. Notice how many hidden assumptions your original steps contained — assumptions that work fine when you are alert and experienced, but that become failure points when you are tired, distracted, or handing the workflow to someone else.

The underlying principle is straightforward: Each step in a workflow should be small enough to complete without ambiguity.
