Flue adds URL-driven sandbox connectors

This is a good wedge because agent teams keep rebuilding the same boring integration layer: sandbox choice, connector wiring, and setup docs. Flue is trying to make that layer composable and repeatable instead of bespoke.

• –The main value is eliminating hand-written connector boilerplate when onboarding a new remote sandbox or service.
• –Letting the agent read a spec and author the connector pushes Flue toward infrastructure-as-instructions, not just another SDK wrapper.
• –If it works well, this could standardize how agent runtimes attach to sandboxes across vendors, which matters more than another isolated integration.
• –The shadcn analogy is smart: it implies generated, editable code rather than opaque magic, which is usually what teams want for critical infrastructure.
• –The pitch is strongest for builders shipping custom agents or internal workflows, not for hobby scripts.
