name	issue-to-regression-test
description	Use this skill when the user asks to fix a bug, references a GitHub issue number, or describes an issue and wants a fix. This skill will guide you through fetching the issue details, scaffolding a standard regression test, writing a failing test, fixing the issue, and verifying that all tests pass. Make sure to use this skill whenever a bug fix is requested.

Issue to Regression Test

This skill automates the workflow of fixing a bug reported via a GitHub issue by creating a regression test first.

Workflow

1. Scaffold the Regression Test:

   • If an issue number is provided, use the bundled Node.js script to scaffold the test file.
   • Command: node .agents/skills/issue-to-regression-test/scripts/scaffold-test.js <issue_number>
   • This script will automatically fetch issue details using gh and create a file in src/tests/ with the correct JSDoc header.

2. Refine and Reproduce the Bug:

   • Open the newly created test file in src/tests/.
   • Implement a test case that fails when run against the current codebase.
   • The test should accurately reflect the bug described in the issue.
   • Use vitest for testing. Import describe, expect, it from vitest.
   • Import necessary modules from src/ to test the failing behavior.

3. Fix the Bug:

   • Modify the source code in the src/ directory to fix the reported bug.
   • Aim for a surgical fix that solves the problem without unnecessary refactoring.

4. Verify Fix and Prevent Regressions:

   • Ensure the new test passes.
   • Run ALL tests in the project to ensure no regressions were introduced.
   • Command: npx vitest run

Example JSDoc

/**
 * Regression test for issue #2: Visibility settings from template are not respected
 * https://github.com/brunosabot/streamline-card/issues/2
 *
 * Bug: When configuring visibility in a template, the card would always be visible
 * instead of respecting the visibility conditions.
 *
 * Expected: Visibility settings from templates should be properly applied to the card
