The useful stuff: fewer unnecessary effects, better render performance checks, hydration catches, server component rules, security checks and framework-specific diagnostics.

it's like Lovable for localhost. you prompt → agent edits files on your machine directly
rolling out to beta testers now. DM me for priority
