Hi, @huan. I'm Dosu, and I'm helping the wechaty team manage their backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, you created this issue to propose the creation of a new Puppet called MatrixPuppet. The issue is related to two other issues (#1737 and #1167), and you provided a link to the GitHub repository for more information. However, there hasn't been any activity on this issue yet.

Could you please let us know if this issue is still relevant to the latest version of the wechaty repository? If it is, please comment on the issue to let us know. Otherwise, feel free to close the issue yourself, or the issue will be automatically closed in 7 days.

Thank you for your understanding and contribution to the wechaty community.
