Why Claude Code is considered the strongest coding tool — and when it isn't

The short answer: Claude Code is strongest when a task touches many files at once and needs an understanding of how the project is structured — a cross-module change, a migration, or work in code you did not write. It is a weaker fit when you already know exactly which line to change.

What is technically different about it

Most coding assistants run inside the editor and receive the open file, and perhaps a few neighbours, as context. Claude Code runs from the terminal with access to the repository: it searches on its own, reads what it needs, runs commands and checks the result. That difference is not convenience — it changes which tasks are possible at all.

In practice it means you can hand it a task phrased as an intent rather than an instruction. "Find everywhere price is calculated and consolidate it" is a task that requires a survey first and writing second. That survey is exactly the part that consumes the most human time in unfamiliar code.

When it is not the right choice

When you are sitting inside a file and know what to write, an agent that begins by scanning the repository is a delay. Editor autocompletion hands you the line immediately. The same applies to visual design work, where you need to see the result and tune it: the terminal feedback loop is too slow for that.

And there is a further limit worth saying out loud: the less well-defined the task, the worse the result, and that holds for every agent. We wrote about the process that kept this from turning into technical debt in our piece on working with an agent in a team.

What does that mean per task type?

The split that works in practice runs along two axes: how many files are involved, and how familiar the code is. As both rise, the advantage of an agent that searches for itself grows; as both fall, the editor wins.

• A migration or cross-module change — the largest gap, because most of the work is locating rather than writing.
• Entering code inherited from another team: asking questions about the system before touching it.
• Fixing a bug that starts with reproduction and running tests, because the agent runs and checks rather than only suggesting.
• Adding tests to an existing module, where the pattern is known and the work is scope.
• Correcting typography or spacing on a single screen — here the editor is the better tool.

Is it worth switching to?

If most of your work is maintaining an existing system, then yes, and the difference is noticeable in the first week. If most of it is building something new from scratch against a design that keeps changing, the difference is much smaller, and it is worth keeping both kinds of tool available.

We use both. Which one gets opened is decided by the shape of the task rather than by preference, and in practice it falls out fairly sharply: anything touching more than three files goes to the agent. If you are weighing the two, we have a direct comparison.
