A good workflow makes it easier to return to the work. The goal is fewer moments spent reconstructing context and more moments spent solving the actual problem.
Leave a clear starting point
Before editing, describe the result in one sentence. Name the behavior that should change and the smallest check that would demonstrate it. This keeps a small fix from becoming an accidental rewrite.
When the work really is a rewrite, write down the parts that matter: content, paths, interactions and the constraints that the new system must respect.
Build one useful slice
Get a narrow path working from input to result. That first slice exposes mismatched assumptions earlier than a folder full of unfinished abstractions.
For a website, this might mean one route with its real typography, one working action and a mobile layout. For a tool, it might be a single command operating on a small example.
Keep feedback close
npm run typecheck
npm run lint
npm run build
These checks answer different questions. Types check contracts, lint catches recurring mistakes, and a production build exercises the actual delivery path. None of them replaces opening the interface and using it.
Finish with a useful handoff
Write down what changed, how you verified it and what is still uncertain. Include a command that works from a clean checkout. If a configuration value is required, give it a name and a clear place to live.
The best final note is one that makes the next session easier, whether that session belongs to you or somebody else.
