Why do edge cases and the 'why' still trip up my specs?

You can produce a spec. The sections are filled in, the words are there. But ask you why this and not that, and you hesitate. An edge case shows up — and someone else found it, not you. This is not a writing problem. It is a thinking problem that writing exposed. You stopped at the first solution instead of mapping every condition it has to survive. And you worked alone, or let the team review only after the spec was 'done' — after the thinking was already locked in. The fix is not a better template. It is a habit: hunt the edges before you write the happy path, and say your reasoning out loud to people who will push back.

There is a method to teach — enumerating edge cases and writing rationale down — but the real change is a habit the team must build and enforce together.

What’s really going on

You write specs because the task demands one, not because you decided what could go wrong. Edge cases trip you because you stop at the first answer that works. The why trips you because you wrote the conclusion, never the reasoning. Fix both the same way: write the reasoning down, then let your pod attack it.

A moveBefore writing the happy path, list ten ways this could fail — do this before you write one solution.

A moveFor every decision, write one sentence: 'I chose X because Y, not Z.' Make the reasoning visible, not assumed.

A moveHand the spec to the teammate most likely to break it — before you call it done.

A moveBan the review question 'does this make sense?' Demand instead: 'what did I miss?'

A moveWhen someone finds an edge case you missed, write down why you missed it, not just the fix.
