• Assert that a lockfile exists without checking if it’s current:

uv lock --check-exists

• Preview what would be locked without writing the lockfile:

uv lock --dry-run

• Lock a specific Python script instead of the current project:

uv lock --script {{path/to/script.py}}

• Upgrade only specific packages:

uv lock --upgrade-package {{package1}} --upgrade-package {{package2}}
