Always explicitly specify the configuration scope using --user or --repo flags when setting configuration values with jj config set. This prevents ambiguity about where the configuration should be stored and ensures settings are applied at the intended level.
Use --user for settings that should apply across all repositories for the current user, and --repo for settings specific to the current repository.
Example:
# Repository-specific configuration
jj config set --repo 'revset-aliases."trunk()"' main@upstream
jj config set --repo gerrit.default_for main
# User-wide configuration
jj config set --user gerrit.default_for main
jj config set --user git.push origin
Without explicit scope specification, it’s unclear whether the configuration will be stored in the user’s global config or the repository’s local config, leading to unexpected behavior and configuration management issues.
