Walkthrough

Enhanced cmd/cli/store/store.go by adding explicit error handling after file write operations and introducing user-facing success messages for configuration updates. The Save, ChangeDefault, DeleteModel, and UpdateAPIKey methods now report write results via confirmation logs without altering underlying data handling or control semantics.

Changes

Cohort / File(s)	Summary
Error Handling and Success Messaging in Store Operations cmd/cli/store/store.go	Added error checking after os.WriteFile calls with immediate error returns; appended confirmation messages (e.g., "LLM provider %s saved successfully", "%s set as default", "%s model deleted", "API key for %s updated successfully") following successful writes in Save, ChangeDefault, DeleteModel, and UpdateAPIKey methods.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

The changes follow a consistent, repetitive pattern across four methods (explicit error assignment, error propagation, and success logging). While covering multiple code paths, the homogeneous nature of the edits—no complex logic, no structural refactoring—minimizes cognitive load. Review focuses on verifying error propagation correctness and message appropriateness.

113-119: Consider separating persistence from user-facing output.

Adding fmt.Printf statements in store methods couples the persistence layer to a specific output format. This creates several concerns:

• Store methods become harder to test (output to stdout)
• Reusability decreases—these methods can't be cleanly used in non-CLI contexts (APIs, background jobs, tests)
• Violates single responsibility principle (persistence + presentation)

The existing pattern in llmSetup.go where the caller handles success messaging is more flexible and maintainable.
