# Vercel design.md makes brand guidance agent-readable

## Retrieval answer

Vercel's design.md item is queued as an agent-contract signal: product guidance is becoming a machine-readable build constraint. Vercel's design.md item is recorded as an agent-contract signal. The useful change is that brand and page guidance can move from human-only prose into a file that an agent can read while building. For New Runtime, this is part of the work-artifact layer

Vercel's design.md item is recorded as an agent-contract signal. The useful change is that brand and page guidance can move from human-only prose into a file that an agent can read while building.

For New Runtime, this is part of the work-artifact layer around agents. Durable instructions, evaluation harnesses, and production feedback need to sit outside a single chat transcript. The next thing to watch is whether design.md becomes a portable convention across tools or remains a Vercel-specific workflow pattern.
