Coding agents clash over dev ports

The "vibe-coding" era is hitting its first physical bottleneck: the local network stack.

• –SILOED SESSIONS: Modern agents operate in isolation, unaware of other active processes or sessions, leading to "restart loops" where agents kill each other's servers to reclaim common ports like 3000 or 8000.
• –PRIMITIVE NEED: The call for a "native coordination primitive" suggests that local environment management must move from manual intervention to a first-class agent protocol.
• –AGENT TEAMING: This is a clear symptom of the shift from "AI as a tool" to "AI as a teammate" where cross-agent resource negotiation is a technical requirement, not a luxury.
• –MCP POTENTIAL: The Model Context Protocol (MCP) could be the ideal vehicle for a cross-editor standard to synchronize local workspace state.
• –INFRASTRUCTURE GAP: Emerging tools like Modelence and coordination layers like Grits are already trying to solve this by abstracting local infrastructure into stable, agent-friendly backends.
