Description

This Agent Skill is used to create, update, and manage GitHub issues using MCP tools. It activates when users want to create bug reports, feature requests, or task issues, update existing issues, add labels/assignees/milestones, or manage issue workflows. Triggers on requests like "create an issue", "file a bug", "request a feature", "update issue X", or any GitHub issue management task.

Something like :

Create new issue & sub issues: Can you look at the list of languages supported by the application, and create issue about i18n, and sub issues for missing european languages

Update an existing issue : Can you update the issue 192 to match the proper template

Create a bug : I have an issue when running the selected test. Can you create an issue with this Error: Locator: getByText('Total : 3') Expected: visible Timeout: 5000ms Error: element(s) not found
