Every project now has a "Voice and rules for your agent" box on the Projects page: who the brand talks to and how, the hooks that work, how a post is built, the X, Bluesky and Threads versions you want, what it never says, how claims are verified. Your agent reads it at the start of every job and follows it over its general rules, and the agent guide has a full playbook to start from. The skill also asks the agent to write every network's short copy in the same draft, so you open it to humanize, not to write the X version.
