From d22f86e2d2e9c419606fb091e6523e3594bd424f Mon Sep 17 00:00:00 2001 From: Scott Miller Date: Tue, 1 Sep 2026 08:37:57 -0600 Subject: [PATCH] feat(mcp): filter comment inbox to unanswered @agent mentions MCP list/summary uses agent_unresolved_count and ?for_agent=1 so human-human threads never reach the model. Replies are stamped agent by the server. Desktop notify still fires on reviewer comments.
