# Feature branches (link to issue)
issue/<number>-<brief-description>
issue/123-add-user-auth

# When no issue exists
feature/<description>
fix/<description>
hotfix/<description>

[ ] Does ONE logical thing
[ ] Leaves codebase working (tests pass)
[ ] Message doesn't need "and" in title
[ ] Can be reverted independently
[ ] Title < 50 chars, body wraps at 72

# Stage changes hunk-by-hunk
git add -p

# Options:
# y - stage this hunk
# n - skip this hunk
# s - split into smaller hunks
# e - manually edit the hunk
# q - quit

# Review what's staged
git diff --staged    # What will be committed
git diff             # What won't be committed

# Separate concerns
git add -p && git commit -m "refactor: Extract database pool"
git add -p && git commit -m "feat(#456): Add query caching"

# Never combine unrelated changes
# BAD:  "feat: Add auth and fix formatting"
# GOOD: Two separate commits

# ALWAYS check reflog first - it has everything
git reflog

# Shows ALL recent HEAD movements
# Even "deleted" commits live here for 90 days

# Undo last commit, keep changes staged
git reset --soft HEAD~1

# Find lost commits
git reflog | grep "your message"

# Recover to previous state
git reset --hard HEAD@{1}

# Safe force push (feature branches only)
git push --force-with-lease

# 1. Start fresh
git checkout main && git pull origin main
git checkout -b issue/123-my-feature

# 2. Work with atomic commits
git add -p
git commit -m "feat(#123): Add User model"

# 3. Stay updated
git fetch origin && git rebase origin/main

# 4. Push and PR
git push -u origin issue/123-my-feature
gh pr create --fill

# 5. Cleanup after merge
git checkout main && git pull
git branch -d issue/123-my-feature

Avoid:
- Long-lived branches (> 1 week)
- Merging main into feature (use rebase)
- Direct commits to main
- Force push to shared branches
- Commits that need "and" in message
- Committing broken code
