The agent board

A board of specialists reviews the build before code is written.

One model writing everything is how you get an app that looks right and behaves wrong.

Specialists, not one prompt

Product, architecture, design, database, backend, security, responsive and QA each get their own pass. They write typed decisions and objections into a shared brief, and the brief gets reconciled before a single file is touched.

Objections actually block

When the security specialist flags a table with no row-level policy, or the responsive specialist flags a layout that overflows at 390px, that is a binding objection. It has to be answered in the spec, not discovered by you after deploy.

Defects get an owner

After the build, findings are classified and routed to the specialist that owns them — runtime to frontend, policy to security, dead links to architecture. Repairs are scoped instead of a blanket “try again” that rewrites your whole app.
