Importing a module named list masks the built-in list type in this scope, reducing clarity; renaming the module (e.g., commands_list) or importing with an alias (from commands import list as list_commands) would avoid overshadowing and make intent clearer. Update the registration accordingly (app.add_typer(list_commands.app, name="list")).

The test invokes cli.py list expecting the command descriptions to print, but this code defines a Typer sub-app with a subcommand also named list; executing cli.py list (without the subcommand) will show the group help, not run the function. To make cli.py list produce the desired output, either move the logic to a top-level command (remove the nested Typer and register the function directly) or change this to @app.callback() so it runs when no subcommand is provided.

Suggested change
@app.command()
@app.callback()

Inconsistent punctuation: first three entries end with a period while the last does not, and this inconsistency conflicts with test expectations (which omit periods). Standardize all entries (either all with periods or all without) and sync the tests accordingly.
