Anthropic's AI coding assistant that can read your codebase and do work for you.
As stated in the literature
Anthropic's agentic coding product that combines Claude with tool use and a workspace harness for software engineering tasks.
Also called: Claude Tools
Why it matters: It's a leading example of moving AI from autocomplete to full agentic software work, reshaping how engineering teams actually use models.
For example, a developer types 'find why the login test is flaky and fix it,' and Claude Code reads the repo, edits files, and runs tests until it passes.

“Claude Code actually got harder to attack through the tool channel — its success rate dropped a couple points, which suggests it specifically watches for injected content in tool results.”Episode 202 — How Do You Know an AI Agent Actually Refused? Check the World, Not the Words
