A field-manual guide to claude code: the assistant that works in your terminal, reads a repo, edits files and runs tasks — with your approval at every step.
Claude code is the assistant that lives in the command line next to your repo. Rather than pasting snippets into a chat, you let claude code read the files straight from disk, so it grasps how the parts connect before it suggests a thing. Tell claude code what you want in plain words and it drafts the change, shows you, and edits only once you agree. For a newcomer, claude code turns a bare terminal into a patient collaborator that happens to type fast.
The whole project is context, not a snippet at a time.
Edits and commands run only after you give the word.
A first run of claude code is quieter than you expect. You open it in a project folder, name a small task, and claude code lays out a plan. Watch it move, approve each step, and claude code makes the edits while noting what changed and why. When a test fails, claude code studies the error and takes another pass. The point of claude code is not sorcery — it is a steady loop of ask, review and confirm a beginner can follow.
A rename, a fix, a tidy-up — low stakes while you learn the rhythm.
Read the plan, approve what fits, and steer the rest.
The terminal tool runs on one Claude account, the very one you chat with. Sign in once and Claude brings the same helper to your repo that answers your everyday questions in the browser. Nothing is cloned; it is one assistant in two seats.
The chat and the terminal run off one sign-in.
The same plain-spoken assistant in both.
Rather think aloud first? Claude ai in the browser answers coding questions in plain words before you open a terminal. However you arrived — a search for claude code, a claude ai prompt, or a first look at models — the same account is waiting, and your sign-in opens both.
Illustrative examples of everyday use, not a promise of any specific result.
The app keeps the assistant a shortcut from your editor.
The coding tool works right in the repo you have open.
Sign in, launch claude code inside your project, and walk through the first step together.
