Step-by-Step Fix
Simplify your prompt
Composer works best with focused requests. Ask for one feature or change at a time. Chain multiple small requests rather than one large one.
Check model availability
Go to Settings > Models and verify your selected model is available. Try switching models if the current one returns errors.
Verify API usage limits
Check your Cursor subscription tier. Free accounts have limited Composer uses. Upgrade to Pro for more requests.
Add relevant files to context
Use @file mentions to explicitly include relevant files in your Composer request. Cursor works better with targeted context.
Restart Cursor and try again
Temporary server issues can cause failures. Restart Cursor, wait a moment, and retry your request.
Frequently Asked Questions
Composer can edit multiple files, but quality decreases with more files. Best results come from 3-5 focused file edits.
Free accounts get limited Composer uses. Pro ($20/mo) includes generous Composer usage.
