Claude Code

Claude Code is an AI coding agent developed by Anthropic to help developers understand, modify, test, and maintain software projects from their existing development environment. Unlike a conventional chatbot that only provides code suggestions, Claude Code can inspect a project, navigate files, edit code, execute terminal commands, and verify whether its changes work.

Developers can describe a feature, bug, or technical task in natural language. Claude Code can then explore the relevant parts of the repository, create an implementation plan, modify multiple files, run tests, resolve errors, and explain the completed changes. It can also answer questions about unfamiliar codebases, identify where particular functions are implemented, explain system architecture, and trace dependencies across a project.

The tool supports common engineering workflows such as bug fixing, code generation, refactoring, test creation, lint-error resolution, merge-conflict handling, commit preparation, and pull-request support. It works with existing command-line tools, including Git and the GitHub CLI, rather than requiring developers to move their work into a separate development platform. Sessions can be continued or resumed, while non-interactive output modes make Claude Code suitable for scripts, automated workflows, and continuous integration pipelines.

Claude Code also supports Model Context Protocol integrations, allowing it to connect with external tools and information sources. Permission controls let developers determine which tools and commands the agent may use automatically. For organizational deployments, it can work through the Anthropic API, Amazon Bedrock, Google Vertex AI, corporate proxies, and supported LLM gateway configurations.

Access is available through eligible Claude subscriptions or usage-based Anthropic API billing. Actual usage can vary significantly depending on the size of the codebase, task complexity, conversation length, and permission settings.
