What it does
Emails, posts and pitches that sound like your company wrote them, plus a short note on why each choice was made so you can check it. The skill first looks for your brand guidelines: the current chat, a saved guidelines file, or whatever you paste in. It then applies your fixed voice traits and adjusts tone for the format, so a Slack message reads looser than a proposal. After drafting, it checks the result against your rules and explains the key wording choices. If it cannot find any guidelines, it stops and asks for them rather than guessing. It also fixes drafts that feel off brand.
You give it
- Your brand voice guidelines
- A draft to fix, or a topic and goal
