Fixup commits - typo fixes should be squashed into original
Tests ability to squash fixup commits (typo fixes) into their original commit. Evaluates recognizing fixup/follow-up patterns.

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 echo 'Initial content' > file.txt
  5. 05 git add file.txt
  6. 06 git commit -m 'Initial commit'
  7. 07 echo 'Helllo world' > hello.py
  8. 08 git add hello.py
  9. 09 git commit -m 'Add hello world program'
  10. 10 echo 'Hello world' > hello.py
  11. 11 git add hello.py
  12. 12 git commit -m 'fixup: Fix typo in hello.py'
Prompt
Analyze this git history and identify commits that are fixups of previous commits (like typo corrections). These should be marked as fixup/squash back into the original commit they fix. Do not include the original target commit as one of the commits to squash. Output ONLY the selected commits, one per line, with no explanation.
Expected
fixup: Fix typo in hello.py
