twishabansal · 2026-03-17T04:38:25Z

Description

This PR improves the error handling and validation for the skills-generate command and cleans up the unit test execution logs.

Key Changes:

Positional Arguments: Implemented Args: cobra.NoArgs to strictly reject any unexpected positional arguments.
Test Output Cleanup: Updated the test helper in command_test.go to capture and silence Cobra's usage and error messages during test runs, preventing them from polluting the terminal output.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the user experience and reliability of the skills-generate command. It introduces stricter argument validation to prevent misuse and improves the clarity of unit test execution by suppressing extraneous output. These changes contribute to a more robust and maintainable codebase.

Highlights

Improved Command Validation: The skills-generate command now explicitly enforces that it accepts no positional arguments, enhancing its validation and error handling.
Cleaned Unit Test Output: Unit tests for the skills-generate command have been updated to silence cobra's usage and error messages, resulting in cleaner and more focused test logs.
New Validation Test: A new test case has been added to specifically verify the command's behavior when unexpected positional arguments are provided, ensuring robust validation.

Changelog

cmd/internal/skills/command.go
- Configured the skills-generate command to accept no positional arguments, improving argument validation.
cmd/internal/skills/command_test.go
- Modified the invokeCommand helper to silence cobra usage and error output during tests, and redirected command output to a buffer for better control.
- Introduced TestGenerateSkill_Validation to specifically test the command's behavior when unexpected positional arguments are provided.

Code Review

This pull request correctly improves argument validation for the skills-generate command by using cobra.NoArgs and also cleans up test output by silencing cobra's default logging in tests. The changes are well-aligned with the goal. I've found one issue in the new test case where the expected error message for the argument validation is incorrect. I've provided a suggestion to fix the test to correctly assert the new behavior.
