How Mika drafts the posts
One post per thing shipped
For a merged pull request or a published release, Mika drafts a post for X: what changed and why someone who uses the project would care. She writes from the pull request and its diff, and adds no claim they do not support.
The weekly thread
Every Friday she drafts a thread of what was merged that week. You can also ask for it at any time from the Marketing tab.
Posting
Clank does not post to X. Each draft has a Post on X button that opens X with the text filled in and the link to the pull request or release attached. You read it, change it if you like, and press post.
House style
No hashtags, no emoji, no exclamation marks. Your tone notes in the repository settings change how she sounds.
