Claude Code is an artificial intelligence-based coding agent software developed by Anthropic. Unlike conventional programming assistants that only provide code suggestions, Claude Code operates as a command-line interface (CLI) tool that can independently read, analyze, and modify an entire codebase. The tool is designed to help developers at various stages of the software development cycle, from exploring a new project and debugging to writing tests and large-scale refactoring.
History and Development
Claude Code was introduced by Anthropic as part of the Claude model ecosystem to meet the need for a more autonomous programming tool. Its main development has been marked by the launch of support for various surfaces, such as a native extension for Visual Studio Code (VS Code) and a redesigned desktop interface. One important milestone was the introduction of the checkpoint feature, which allows developers to "rewind" to a previous state of the code, providing psychological safety when carrying out large tasks. In 2026, Anthropic launched the dynamic workflows feature, which significantly increased Claude Code's capacity to handle complex projects by running hundreds of sub-agents in parallel.
Core Capabilities and Features
Claude Code offers various features that change the way developers interact with their codebases.
Terminal- and IDE-Based Agent
Claude Code runs natively in the terminal and is integrated with various Integrated Development Environments (IDEs) such as VS Code, JetBrains, and a desktop application. Users can start a session with the simple command claude in their project directory. In this mode, Claude can read the repository, edit files, run commands, and ask for confirmation before performing destructive actions. The checkpoint feature ensures that every change made by Claude can be undone at any time.
Dynamic Workflows
The dynamic workflows feature is a flagship capability that allows Claude Code to break complex tasks into several sub-tasks and run them in parallel using tens to hundreds of sub-agents in a single session. This enables Claude to handle work that previously took weeks in only a few days. A published case example is the use of dynamic workflows to port the Bun runtime from Zig to Rust, producing around 750,000 lines of Rust code with a 99.8% test pass rate in eleven days.
Customization and Control
Developers can give Claude permanent instructions through a CLAUDE.md file located at the project root. This file contains coding standards, architectural decisions, and a code review checklist that Claude will read at the start of every session. In addition, teams can create skills to automate repeating workflows (for example, a /ship command) and use hooks to run shell commands before or after certain actions.
Model Context Protocol (MCP)
Claude Code supports the Model Context Protocol (MCP), an open standard that allows AI agents to connect to various external data sources. With MCP, Claude Code can read design documents in Google Drive, update tickets in Jira, or retrieve data from Slack, making it a control center integrated with the tools already used by development teams.
Common Use Cases
Based on Anthropic's official documentation, there are ten main scenarios in which developers most often use Claude Code:
Fixing Failing Tests. When a test fails and the cause is unclear, Claude Code can trace the root problem and propose a fix without the developer first having to identify the source file.
Understanding Unfamiliar Code. Claude can guide developers through how a particular module or function works, explaining control flow and decision points in natural language.
Finding the Location of a Function. Developers can ask where a particular validation occurs, and Claude will return the exact file path and line number.
Classifying Errors. By providing a stack trace or error log, Claude can map it back to the responsible code and explain the cause.
Refactoring with a Plan. Before making large changes across many files, Claude can create a detailed plan of which files will be changed and how they will change, which the developer must approve first.
Writing Tests for Existing Code. Claude can generate new test files that match the project's existing coding style and run them to ensure everything works.
Reviewing Pull Requests. Integrated with the GitHub CLI, Claude can retrieve the diff, review comments, and CI status to produce a PR review or summary.
Onboarding to a New Repository. The /init command allows Claude to scan the project and generate a CLAUDE.md file that summarizes the architecture, build commands, and conventions used.
Handling Issues End-to-End. With MCP connectors, Claude can read a ticket, implement a fix, and validate it in a single conversation without having to switch tools.
Turning Repeating Tasks into Skills. Developers can create custom commands (such as /ship) that run a series of automated steps (for example, running tests, a linter, and creating a commit message).
Models and Pricing
Claude Code uses Anthropic's latest AI models, including Claude 3.7 Sonnet and Claude 4 Opus. It is available in several subscription plans, ranging from Claude Pro for individual use to Enterprise plans for large organizations. Team and Enterprise plans provide user management features, SSO, and usage analytics. Companies also have the option to run Claude Code through their own cloud infrastructure such as Amazon Bedrock, Google Cloud Vertex AI, or Microsoft Foundry, ensuring that data remains under their control and meets compliance standards such as SOC 2 Type II.
