Earlier, the phrase “Zero to Production in Days” was used to describe the rapidly approaching future where practical applications of coding agents will rapidly accelerate the development of software. After seeing Claude Code in use at my employer for a while, I’m starting to think this description is not quite right.

The most productive people I see using Claude Code treat it as an intern. They give it a lot of information up front, break down exactly how things should be done, and leave it to execute a very well defined plan. Then they have it write itself notes, and commit those notes to the source repo so that the rest of the team can have that available when they go fishing. They do not depend on it for critical thinking. Nor do they start with “Claude, I want a spaceship, build it for me, make no mistakes, don’t hallucinate.” Instead, they spend a great deal of time creating clarity for the agent, so that when it executes, it can one or two shot the exercise.

That effort up front is not “zero.”

Indeed, that effort is where the hard work really is in the software industry. That’s where it was before AI and that’s where it still will be afterwards. You need experience to be able to do that. It requires taste. Taste comes from having eaten many things and knowing the differences between them. That’s not zero either.

This is why I’m more convinced than ever that engineers are not going to get replaced by the technology. A finance person told me they tried to use Claude to create a form that was highly customized. It generated an HTML file. He gave it to someone else after he had filled it out, and was surprised when the recipient did not see any of his changes. This person knew nothing about web development and did not understand that an HTML file on disk would not actually do anything without something on the server to process the form input.

The coding agent is a multiplier; if you have decent tools, then that multiplier is probably greater than 1. It doesn’t matter what it is if the number you are multiplying is zero.
