Claude Codeとは何か

Claude Code is an agentic coding tool. It reads your codebase, edits files, and runs commands, so it takes part in your work instead of only answering questions about code. The talk argues that such a tool should feel more like a teammate: instead of waiting for you to press enter, a teammate notices when something breaks and acts on its own. This is the idea of a proactive workflow, in contrast to a reactive one that only responds after you ask. To make this practical, the new routines feature lets you define a prompt, the repos and connectors to use, and a trigger that starts the session — on a schedule, through an API call, or on a GitHub event. Two things then decide how well it works: the context you give it, and its steerability, since you can open a running session to steer or resume it. The goal is simple: move Claude Code from a tool you drive step by step into a teammate that acts for you.
