# CULP (Claude Usage Limits)

> A Claude Code plugin and a cross-platform CLI. It works on the harness around
> Claude Code, the hooks it runs and the context it carries from turn to turn,
> and cuts what that harness costs. It does not change the model you selected
> and it does not raise a limit Anthropic set.
