Good call. Let's add this clarity 👍
It's also good to first clear before running build like
npm run clean; npm run build

Just to clarify: you mean the command was there but CLI wouldn't load its help?

Since we're writing in TypeScript, you need to build to transpile the code to JavaScript, so the need to build is obvious. But I suspect there's more to your observation so would like to clarify it before we proceed with defining a suitable a solution.

While developing I usually use npm run watch. However when you create a new command, you are unable to test it locally because CLI says this command doesn't exist.
Only after doing an npm run build, CLI updates its command list and knows it's there.
This is because of #5608

Understood. I suggest that we revisit the watch command and see if there's a different way to orchestrate it so that you get everything you get from build + watch. It doesn't make sense for watch to be incomplete.

#5608 is not the only culprit. We had the same issue for a long time, previously linked to Power Platform app templates. Now they're gone, the reason has changed, but the problem remains.

Can I work on it?

All yours @SmitaNachan!
