One draft, three reviewers, one agent
Here's a normal week at Brambleway Coffee, a small roaster that ships beans by subscription. Theo, who runs content, asks his agent for a 1,200-word post about why they roast on Tuesdays and ship by Thursday. The agent saves drafts/roast-to-door.md and runs gander watch on it. Theo drops the link in the team channel.
Imogen, the editor, opens it first and highlights the intro. "This takes three paragraphs to get to the point." Hana, who owns claims, reads the middle section and starts a thread on one sentence. "We can't say 'freshest in the country.' We've never measured that." Imogen replies that the fix is to say what they actually do: roast Tuesday, ship Thursday. That's a conversation between two people, so it stays a normal thread. The agent never sees it.
Then Hana starts a new comment on that sentence with agent connect: "@agent replace 'freshest in the country' with 'roasted Tuesday, shipped by Thursday'." That lands in Theo's agent session, the one that wrote the draft. The agent edits the local file, replies in the thread with what it changed, and every open tab updates. Nobody pastes anything into a prompt.
Nadia, the founder, reads it that night on her phone. The new line about roasting Tuesday and shipping by Thursday is already there, on the same link Theo sent that morning, so nobody has to resend anything.
When the draft is done, it goes to the CMS the way it always did. The file on Theo's machine was the draft the whole time.
