Claude Code

Claude Code is a coding agent that lives in the terminal instead of an editor sidebar. The practical difference is scope: it navigates the whole repository, runs the build and test commands, reads what failed and iterates, rather than suggesting a completion at the cursor. That makes it good at the work that spans files — a rename that touches thirty call sites, tracing why a test is flaky, or turning a described change into a reviewable diff. It also means you supervise outcomes rather than keystrokes, which is a different working posture than autocomplete.
