# Description A new command to simplify assertions for `false`. The name is just a draft, though I could not come up with a better name. I have rejected `assert false`, because I would have to rename `assert` to `assert true` which would break the compatibility and worsen the shell experience of the good old `assert`. Another idea I have rejected was something like `assert_false` to keep it consistent with the naming convention of our stdlib. I am open to suggestions :) # User-Facing Changes Just a new command # Tests + Formatting - [x] Done # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. -->
