From bbdad2a0771bf4483df1bbd50cf3eecbf4d34100 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Mon, 7 Sep 2026 15:59:04 +0000 Subject: [PATCH] polish the desktop loop: premium review gate and MCP bring-up Point Cursor/Copilot/Claude MCP at run_mcp.sh so empty interpolations cannot hide .env. Treat blank OLLAMA_* as unset. Spell out accept / rewrite / reject in client instructions, tool docs, and system prompts before live GPU use. Local still does not apply.
