services/file_system_config.go:34

• The field name 'CachePath' conflicts with its JSON tag 'fs_root_path' and comment indicating a file system root, which may lead to confusion regarding its actual purpose. Consider updating the JSON tag and comment to reflect that this field represents a cache path, or rename the field to match its intended usage.

CachePath   string   `json:"fs_root_path"` // CachePath is the root path for the file system.

cli/cmd/config.go:98

• [nitpick] The flag '--init' may be ambiguous regarding its purpose of saving the configuration to a file. Consider renaming the flag to '--save-config' or a similar descriptive name to better convey its functionality.

configCmd.PersistentFlags().BoolVar(&initial, "init", false, fmt.Sprintf("Save configuration to %s", filepath.Join(mlConfig.BasePath, MLConfigName)))
