The Voice Builder produces a MY_WRITING_STYLE.md file. That file is yours. It documents:

Once that file exists, the Post Writer has everything it needs. You stop re-explaining yourself every single time. You stop getting output that sounds like it could have come from anyone. And you stop spending 45 minutes on a post that still does not feel right.

You can also update the file anytime. Your voice evolves, your topics shift, your audience changes — the skill keeps up.
