Stabilize CLI design: what I learned (062)

I used this as a focused experiment, and I wrote it down while it was still fresh.

Why I touched it

I started with a narrow question and kept adding complexity only when the behavior changed.

I kept everything practical by using a short loop around CLI design.

Implementation notes

I started with a narrow goal: keep the same behavior, reduce one risk, and keep rollback trivial. I moved from vague ideas to explicit rules before touching production paths.

Validation checklist

• Capture real inputs
• Check timeout behavior
• Track latency before and after
• Add follow-up reminder

Snippet

set -euo pipefail

node --version
npm ci
npm run lint
npm run test

I also ran this while working from a family dinner prep for one IRL pass.

What I kept

• This cli design setup now has a measurable reduced false positives path.
• I keep the same format for every future run.
• If it can be explained in one checklist, it usually scales better.
