Claude Code

Anthropic · · Agent

Anthropic released Claude Code as a limited research preview: an agentic coding tool that works in the terminal, reading and editing a repository and running commands.

Why it matters

Established the terminal as the agent's home rather than the IDE, a shape that Google, OpenAI and xAI all copied within eighteen months. It also became the reference harness that later open-source agents were benchmarked against.

This is LLM World's historical reading, not a claim by Anthropic. The facts above and the sources below are what it rests on.

Anthropic's own announcement, dated Feb 24, 2025 on the page. The post's headline subject is the Claude 3.7 Sonnet model release, which belongs in the model dataset; Claude Code is introduced in the same post and is the milestone here. General availability came later (May 2025) and is a separate date if one is wanted. No archived capture recorded; one should be added.
