From eae3a91ef528fd59bc641cad3f5b3202260af342 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Mon, 21 Sep 2026 17:07:34 +0000 Subject: [PATCH] Add fast reception path for greetings before heavy agent runs Route simple chat through an optional local OpenAI-compatible reception model so threads.send does not always enqueue a full sandbox-backed run. Clear work prompts still escalate to the bot's configured work model.
