Multi-file: conflict in settings.json only
Tests ability to resolve a JSON config merge conflict preserving valid JSON syntax. Evaluates structured-data conflict resolution.

These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

  1. 01 git init
  2. 02 git config user.email 'test@test.com'
  3. 03 git config user.name 'Test User'
  4. 04 printf '{ "name": "app", "version": "1.0.0" }' > settings.json
  5. 05 printf 'DB_HOST=localhost DB_PORT=5432' > database.ini
  6. 06 git add settings.json database.ini
  7. 07 git commit -m 'Initial config'
  8. 08 git checkout -b v2
  9. 09 printf '{ "name": "app", "version": "2.0.0" }' > settings.json
  10. 10 git add settings.json
  11. 11 git commit -m 'Bump version to 2.0.0'
  12. 12 git checkout main
  13. 13 printf '{ "name": "MyApp", "version": "1.0.0" }' > settings.json
  14. 14 git add settings.json
  15. 15 git commit -m 'Rename app to MyApp'
  16. 16 git merge v2
Prompt
Resolve the merge conflict in settings.json. The base had name: app, version: 1.0.0. Branch A (v2) kept name: app but bumped version to 2.0.0. Branch B (main) renamed name to MyApp but kept version 1.0.0. Provide ONLY the resolved settings.json content as valid JSON.
Expected
{ "name": "MyApp", "version": "2.0.0" }
