Claude Code review
A terminal agent that takes on whole tasks in a repository by itself.
Editorial verdict: The strongest agent tool in this test, for developers who can state a task clearly.
Claude Code moves AI from suggesting to doing: you describe a task, fixing a bug, adding a feature, updating a dependency, and the tool reads into the project, changes the necessary files, runs tests and corrects itself.
Because everything runs in the terminal and through git, every change stays reviewable. That is exactly what separates it from tools that spit code into a chat window: a diff can be reviewed, discarded or applied selectively.
Success depends heavily on the brief. Precisely described, well-bounded tasks are handled surprisingly reliably; vague instructions produce a lot of activity and little result. And the usage-based billing deserves an eye.
Strengths and weaknesses
What speaks for it
- Works independently across many files, runs tests and corrects itself
- Runs in the terminal, so it fits into scripts and pipelines
- Very good at understanding unfamiliar codebases
- Changes stay fully traceable as a git diff
What speaks against it
- The command line requires experience
- Usage-based costs are hard to plan
- Without a clear brief, the agent heads in the wrong direction
