config path not set

Error message

config path not set

What it means

SaveProviderModel refuses to run when the package-level ConfigPath variable has not been initialized. The function performs surgical text edits on the TOML file at ConfigPath, so without a path there is nothing to safely modify, and it fails rather than guessing a location.

Solutions

1. Ensure LoadConfig (or explicit assignment to config.ConfigPath) runs before SaveProviderModel
2. Pass/point the binary at a config file path (e.g. --config flag) at startup
3. In tests, set config.ConfigPath to a temp file path in setup

Example fix

// before
config.SaveProviderModel("proj", "kimi", "model-x") // ConfigPath == ""
// after
config.ConfigPath = "/etc/cc-connect/config.toml"
config.SaveProviderModel("proj", "kimi", "model-x")

if config.ConfigPath == "" {
	return errors.New("call LoadConfig or set config.ConfigPath first")
}

func canSave() bool { return config.ConfigPath != "" }

if err := config.SaveProviderModel(p, prov, model); err != nil {
	if err.Error() == "config path not set" {
		config.LoadConfig(defaultPath) // then retry
	}
	return err
}

When it happens

Trigger: Calling SaveProviderModel(project, provider, model) before LoadConfig/any code set config.ConfigPath — typically a library consumer invoking save APIs without loading config first, or a binary invoked with no config flag.

Common situations: Running a CLI subcommand that persists model changes without the --config flag; tests calling SaveProviderModel directly without setting ConfigPath; refactoring that removed the init call that sets ConfigPath.

Understand the failure class

Background: "missing required config value" errors: why libraries refuse to start when a configuration key is empty, unset, or blank — this error's family across 48 libraries.
