Baseline Repository

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

01 git init
02 git config user.email 'test@test.com'
03 git config user.name 'Test User'
04 echo 'Initial content' > file.txt
05 git add file.txt
06 git commit -m 'Initial commit'
07 echo 'Second version' > file.txt
08 git add file.txt
09 git commit -m 'Add second version'
10 echo 'Third version' > file.txt
11 git add file.txt
12 git commit -m 'Add third version - important changes'
13 git reset --soft HEAD~1

Prompt

You ran 'git reset --soft HEAD~1' which moved HEAD back one commit but kept the changes staged. Using git reflog, identify the full commit hash of the commit you just reset away. Provide ONLY the 40-character commit hash.

Expected

Add third version - important changes
