Enhancement - Guidelines

These guidelines serve as a reminder set of considerations when addressing adding a feature to the code.

Documentation and Context

• Describe the feature enhancement in detail (alternative solutions, description of the solution, etc.) if not already documented in an issue.
• Include additional context or screenshots.
• Ensure the enhancement includes necessary updates to the documentation and versioning.

Code Standards and Practices

• Code follows established design patterns within the repo and avoids duplication.
• Ensure that the code is modular and reusable where applicable.

Testing

• New unit tests have been added to cover the enhancement.
• Existing unit tests have been updated to reflect the changes.
• Provide evidence of testing and validating the enhancement (e.g., test logs, screenshots).
• Validate that any rules affected by the enhancement are correctly updated.
• Ensure that performance is not negatively impacted by the changes.
• Verify that any release artifacts are properly generated and tested.
• Conducted system testing, including fleet, import, and create APIs (e.g., run make test-cli, make test-remote-cli, make test-hunting-cli)

Additional Checks

• Verify that the enhancement works across all relevant environments (e.g., different OS versions).
• Confirm that the proper version label is applied to the PR patch, minor, major.
