Fix: Cursor Composer Multi-File Edits Are Incomplete or Wrong
Quick Answer
Limit Composer to 3-5 files per request. After each edit, verify all files are consistent before requesting more changes. Use @file to explicitly list every file that needs editing.
Quick Fix Summary

| Fastest fix | List all files explicitly |

Symptoms
- !Composer edits 2 out of 5 files correctly but skips the rest
- !Changes in one file don't match the changes in another
- !New component created but not imported in the parent
- !Database schema updated but queries still use old column names
Step-by-Step Fix
List all files explicitly
In your Composer prompt, list every file: 'Edit these files: @src/lib/db.ts @src/app/api/users/route.ts @src/components/UserList.tsx. Add a 'role' field to the user type, query, and display.'
Verify after each batch
After Composer finishes, check every file it modified. Run npx tsc --noEmit to catch inconsistencies. Fix issues before requesting more changes.
Break into sequential steps
Instead of 'refactor the entire auth system', use: Step 1: 'Update the database schema in @src/lib/db.ts'. Step 2: 'Update the API routes to match the new schema'. Step 3: 'Update the frontend components'.
Use the diff view
Composer shows diffs for each file. Review every diff before accepting. Reject changes to files that look wrong and re-prompt for just those files.
Frequently Asked Questions
Composer can edit many files, but quality drops after 5-7 files. For best results, limit to 3-5 files per request and do multiple rounds.
The AI prioritizes files it considers most relevant to your prompt. Explicitly listing files with @file ensures none are skipped.
