# Claude Code

Anthropic's command-line AI agent that works autonomously on software development tasks.

## Definition

Claude Code is a command-line AI agent built by Anthropic that operates on software codebases autonomously. Unlike AI code editors (such as Cursor or GitHub Copilot) that assist developers interactively in real time, Claude Code accepts task descriptions and executes them — reading files, writing code, running commands, checking for errors, and iterating — without requiring the developer to supervise each step.

Claude Code is not an integrated development environment. It runs in a terminal and interacts with the filesystem and shell directly. To use it effectively, a project should include a CLAUDE.md file in the root directory — a guidance document that tells Claude Code what conventions to follow, which commands are available, which directories to leave alone, and what tools it has permission to use.

Claude Code is built on Claude 3.5 Sonnet and runs through the Anthropic API or Claude Pro/Max subscription. It connects to external tools through [Model Context Protocol (MCP)](/glossary/model-context-protocol), which allows it to interact with CRMs, databases, and communication platforms as part of autonomous workflows.

Common use cases include: multi-file refactoring, batch content operations, automated code audits, build verification, and test generation — tasks where the desired outcome is defined clearly enough to delegate entirely.

## Why It Matters for Middle Market Companies

The productivity case for Claude Code rests on a specific distinction: some coding and operations work requires active judgment at every step (you need to be in the loop), and some requires execution of a well-defined task (you'd rather hand it off and check the result). Claude Code handles the second category.

Most AI code editors — even excellent ones — still keep you in the loop on every suggestion. That's appropriate for exploratory work. For repetitive, well-specified tasks, that interaction overhead adds up. Claude Code eliminates it.

At Prometheus, Claude Code handles content audits, batch metadata updates, TypeScript checks, and multi-file maintenance tasks. These tasks ran in the background while our team focused on higher-judgment work. The throughput gain on well-specified, repeatable tasks is significant.
