## What is it?

The pre-commit framework installs the tools your Git hooks use (linters, formatters and their language runtimes) into isolated environments in `~/.cache/pre-commit`, one per hook repository and version. Environments for old hook versions stay when you update your configuration.

## What happens if you delete it?

pre-commit installs the environments again the next time a hook runs, which makes that commit noticeably slower. Your `.pre-commit-config.yaml` files are not affected.

## How to remove it properly

Run `pre-commit gc` to remove only environments no longer used by any configuration, or `pre-commit clean` to remove them all; both are pre-commit’s own commands. Moving the folder to the Trash is equivalent to `pre-commit clean`.
