What it is

A legacy robots.txt token from before Anthropic consolidated on ClaudeBot. It is still widely present in robots.txt files and costs nothing to keep, but it is a control token rather than a bot you will see in logs.

What blocking it costs you

None. Nothing crawls under this name today; keeping the rule is harmless insurance.
