What it does
A brand voice slips when many people write and no one checks. Copy goes out that sounds like a different company, or makes a claim you do not make. A single check helps, but a fix can add new slips, and nobody notices the same mistake coming back every month. This agent checks each draft against your voice guide and ranks what it finds. It rewrites only the flagged lines, never changes a fact, price or claim, and checks again. It stops after three rounds and gives a person what is left. It also counts which slips repeat across drafts, and when one shows up three times, it suggests a rule for your guide. It never publishes or sends anything.
You give it
- The draft, and where it will be used
- Your brand file, with voice, claims and what you do not say
- Your voice guide, if you have one (optional)
- Proof for any claims in the draft (optional)
- A buyer brief (optional)
You get
- A pass or not-passed result, and how many rounds it took
- The final draft with changed lines marked, and the slip each fixed
- Any flag left for a person, including claim and legal flags
- A count of repeat slips across drafts
- A suggested guide rule when a slip repeats three times
Use it when
- Several people or tools write your copy and it does not always sound like you.
- You want every ad, email or page checked before it ships, the same way each time.
- The same voice mistakes keep showing up and you want to fix the cause.
How to use it
- Start a chat with the agent. In Claude Code, add it as a skill or save it in .claude/agents, then ask it to review a draft.
- Give it the draft and your brand file. The first time, give it your voice guide, or let it build one and approve it.
- Read the final draft and the open flags. Fix what is left yourself.
- Say yes to any guide rule you want added.
- Run it on every draft. It keeps the slip count in a review folder.
