Claude Code

Overview

Claude Code is Anthropic's agentic coding tool. It runs in the terminal and also works through IDE integrations. You describe a task in plain language, and it reads the relevant parts of your project, proposes edits, runs commands and tests, and reports back. Project instruction files let you record conventions the agent should follow in every session. It suits developers who want an agent to handle multi-file changes, debugging and refactoring inside an existing repository. It is less suited to people who want a point-and-click experience, or to anyone who plans to apply changes without reviewing them. Access requires a Claude subscription or API billing, and long sessions on large codebases can use a significant amount of usage.
