Claude Code

Tool Overview

Claude Code is Anthropic's agentic command-line coding tool that brings Claude's advanced reasoning directly into the terminal, enabling developers to edit files, debug issues, refactor codebases, run shell commands, and manage git workflows through natural language conversation. Unlike IDE-based coding assistants that operate within a single file context, Claude Code works repository-wide — it can search across directories, read and understand multi-file codebases, make coordinated edits across multiple files, and execute tests to verify changes are correct. The tool excels at complex software engineering tasks including large-scale refactoring, dependency updates, test writing, code review, and technical documentation generation. Claude Code integrates with git workflows to create properly structured commits with messages, handle merge conflicts, and maintain clean project history. Built on Claude's industry-leading 1-million-token context window, Claude Code can ingest entire project directories in a single session, making it uniquely suited for legacy codebase modernisation, cross-service architectural changes, and open-source contribution workflows where understanding the full codebase context is critical for correct modifications.
