Composer turned into a complete Moron

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Just like Opus deteriorated HARD after 1-2 weeks. Composer is now a completely useless lobotomite. It’s like you ask your tab completion to do agentic work.

Steps to Reproduce

use the agents.

Expected Behavior

Agents are just as good as on Week 1 of their release.

Operating System

Windows 10/11

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. To help the team investigate, could you please share:

  • Specific examples of Composer requests where quality got worse - what you asked for and what you got instead of the expected result
  • 2-3 Request IDs for several such failed requests
  • Which modes you used (ask, agent, plan)
  • Does it reproduce in a new chat?

Let me know these details.

  • Specific examples of Composer requests where quality got worse - what you asked for and what you got instead of the expected result

    ”make logical/sensible commits” with around 30 changed/moved files and 4-5 bundlable commits

  • 2-3 Request IDs for several such failed requests

    I tried with Sonnet 4.5 as well. but I probably reverted and started the same chat with another agent (you might have them, so those request id’s could be around 7-8 tries)

  • Which modes you used (ask, agent, plan)
    Agent

  • Does it reproduce in a new chat?
    Yep, did multiple chats with restarts, resets, stashes, and Composer even managed to undo even more commits than it should^^

all in all they seemed to have their special braindead sunday :wink: (or you havent given them enough food for thought)
