Cathryn Lavery shares a practical AGENTS.md rule for anyone using Tailscale across multiple machines: instruct your coding agent to always share a Tailscale link instead of localhost for anything running locally (previews, review pages, dashboards), publish with tailscale serve, verify the link works itself, then send it. This lets you open agent-built previews from your phone and other computers — solving the classic localhost-unreachable pain in multi-device workflows.
