Workaround

Unfortunately, there is no known workaround for this issue. The /doc command is supposed to add JSDoc comments to functions, but instead, it removes large parts of the code file. This makes it difficult to use the /doc command without risking losing important code.

Conclusion

The issue with Github Copilot removing code instead of adding comments is a serious problem that needs to be addressed. The /doc command is a useful feature that helps developers document their code, but it is currently unusable due to this issue. We hope that the Github team will investigate this issue and provide a fix soon.

Recommendations

  • Github Team: Please investigate this issue and provide a fix as soon as possible.
  • Developers: Avoid using the /doc command until this issue is resolved.
  • Users: If you experience this issue, please report it to the Github team and provide as much information as possible.
