Show HN: Tired of duct-taping access control into agent prompts. Here's the fix (github.com) AI

Show HN post for the open-source “cast” project, described as a self-hosted harness for multi-user, multi-agent Claude setups, aiming to replace prompt-based access control with centralized, configurable identity and routing. The author claims that with Cast the access rule is kept out of the model’s prompts to prevent it from being argued around. The README-style text outlines setup on a Mac Mini or other container runtime, starting a local dashboard, and using a web chat builder plus “Cast skills” to build and update agents.
