### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug When I have selected plan mode, it will often still edit files and make changes even though it is not in Agent mode yet. This is especially bad with Gemini 3 Pro model. ### Steps to Reproduce 1. Select Plan mode 2. Select Gemini 3 Pro model 3. Describe a change request 4. Multiple files changed, essentially completing the “plan” before I have even reviewed or approved the plan. ### Expected Behavior A plan to be _safely_ produced, no code file edits. Can use other tools to explore the code though. ### Operating System MacOS ### Current Cursor Version (Menu → About Cursor → Copy) Version: 2.2.23 VSCode Version: 1.105.1 Commit: b3c95a7981bb3057526f1f865e8c307a9911ce00 Date: 2025-12-15T03:10:57.241Z Electron: 37.7.0 Chromium: 138.0.7204.251 Node.js: 22.20.0 V8: 13.8.258.32-electron.0 OS: Darwin arm64 23.4.0 ### For AI issues: which model did you use? Gemini 3 Pro ### For AI issues: add Request ID with privacy disabled c226d6ab-0955-4e56-89a5-c538e982b6bb **Update** : That didn’t take long, another one: 155606ce-8030-48ba-a83a-a3735b96f663 This happens often. However, hopefully these 2 are sufficient for Cursor team to debug and fix. ### Does this stop you from using Cursor Sometimes - I can sometimes use Cursor ---

Hey, thanks for the report. Plan mode shouldn’t edit files until you hit Build and approve the changes - this is a serious issue that’s already on our list. Thanks for the Request IDs - they’ll help the team track the problem. In the meantime, try: - Hit Undo All right away if files change before you press Build - Switch to Claude 4.5 Sonnet or GPT-5 instead of Gemini 3 Pro - Plan mode works more stably with them - Use Ask Mode if you need to view files safely without risking changes This is a bug on our side with model-specific behavior. The team is already working on a fix. ---

@deanrie : Using Gemini 3 Pro and Gemini 3 Flash both have this bug. Request ID with Gemini 3 Flash: 05e0d2ca-23ee-4861-be5a-10ea45556e10 Switching to another model works reliably. Ask mode has been safe, good to know that’s a fact. Thanks! ---
