Webster is the seed of self improvement for small businesses. A council of Claude Managed Agents runs every week on an SMB's website, critiques it from a bunch of angles, proposes changes, applies them, and verifies the result. Then it does it again next week. The page gets better on its own. The business owner never logs in.

I've been in marketing for years and I've watched local service SMBs lose to the same problem on repeat: no time, no budget, no expertise to keep their landing page earning. And the bigger businesses that do have the budget? They burn it on agencies producing generic pages that don't even convert. Webster replaces that with an autonomous weekly experiment loop. The site organically shapes itself to whatever signal earns the most meetings booked or products sold. More bookings → more time and money for the owner → more trust in AI → more investment in the layer providing it, which in this case is Anthropic's Managed Agents.

The council is nine preregistered Managed Agents: a Haiku 4.5 monitor, five Sonnet 4.6 specialist critics (SEO, brand voice, compliance, conversion, copy), an Opus 4.7 redesigner, an Opus 4.7 planner, and an Opus 4.7 visual reviewer. The hero mechanic is Critic Genealogy: when the council hits a blind spot none of the existing critics own, the orchestrator authors a brand new critic spec, registers it at runtime via POST /v1/agents, and immediately invokes it via POST /v1/sessions. The system grows the intelligence it needs as the surface it works on evolves. Public beta runtime agent creation is what made this real.

For the demo I got sign off from one of my existing clients, Nicolette Richer (Richer Health), to use her brand on a demo landing page. The 10 week evolution in the video is a simulation, as faithful as I could make it, of what Webster would do running weekly against that page. A Synthetic Analytics Agent reevaluates the page each week so every council run reacts to real consequences of last week's changes, not static prebaked numbers. A 1:1 simulation set under agents/simulation/ mirrors the production council so the timelapse runs without touching the live registration.
