Your brand guidelines are not a brand code
Most marketing orgs can't answer the most basic question of the agentic era: what is a hard NO for our brand?
HBR ran a piece making the case for a “brand code” — a machine-readable knowledge base that both people and AI agents can act on. Good piece. The risk is how most CMOs will read it: as a slicker version of brand guidelines.
It's not.
Brand guidelines tell humans how to make consistent decisions. A brand code tells an agent what decision to make autonomously when no human is in the loop. The gap shows up the first time your agent ships 1,000 pieces of content overnight and 80 of them quietly contradict something senior leadership would have flagged in four seconds.
Try this: ask your team to list 10 things your brand would never do. Half the answers will be too vague for an agent to execute on. “We don't make claims that aren't backed by data” — what counts as a claim? Backed by what? A senior human knows. An agent has to be told.
At Vitalpax we kept a list of brand DON'Ts — including “never imply a product cures a specific condition,” which in supplements is a legally binary line. It used to be a three-line doc. When we wired up an AI for product copy, we had to expand it into dozens of rules with concrete examples and counter-examples. The first AI draft cleared the whole list. The second draft, no humans in the loop, drifted on one of the legal-exposure rules. Without a test set, we wouldn't have caught it.
Three questions for any CMO this quarter. One: could a junior copywriter produce 90% of your brand-safe content from a one-page doc? If no, you've been running on senior judgment — and that doesn't transfer to agents. Two: where's your test set? Fifty to a hundred concrete on-brand and off-brand examples; abstract rules can't be measured. Three: who owns the brand code? Not “brand strategy.” A named person with authority to stop the agent from shipping when it fails the suite.
Brand guidelines were a document. A brand code is software. Most marketing orgs aren't yet staffed to ship and maintain software.
