          TASK : FIND RELATED ISSUES

          Using the `gh` CLI tool, search through existing issues on Github.
          Find related or similar issues to the newly created one and list them.
          Do not list the new issue itself (it is #${{ github.event.issue.number }}).

          Consider:
          1. Similar titles or descriptions
          2. Same error messages or symptoms
          3. Related functionality or components
          4. Similar feature requests

          ---

          POSTING YOUR COMMENT:

          Based on your findings, post a SINGLE comment on issue #${{ github.event.issue.number }}. Build the comment as follows:

          - If no related issues were found, do NOT comment at all.
          - If related issues were found, include a section listing them with links using the following format:

          [comment]
          This issue might be similar or related to the following issue(s):

            - #[related_issue_number]: [brief description of how they are related]
            - #[related_issue_number]: [brief description of how they are related]
            ...

          Remember:
            - Do not include the comment tags in your actual comment.
            - Post at most ONE comment combining all findings.
            - If you didn't find issues that are related enough, post nothing.
            - You have access only to the `gh` CLI tool - don't try to use other tools.
