name: Git Environment description: "Create development environments with git worktrees, branches, commits, and push to remote. Auto-applies for git workflow tasks."

Git Development Environment Workflow

Automates common git development workflows for HyperShift including worktree creation, branching, committing (with proper format), and pushing to remotes.

Configuration

Load environment variables from dev/claude-env.sh:

source dev/claude-env.sh

Environment Variables

Variable	Default	Description
`GIT_FORK_REMOTE`	`enxebre`	Your fork remote name
`GIT_UPSTREAM_REMOTE`	`origin`	Upstream remote (openshift/hypershift)
`GIT_BASE_BRANCH`	`main`	Base branch for new features

Workflows

Create New Development Environment

With worktree (parallel development):

# Fetch latest
git fetch $GIT_UPSTREAM_REMOTE $GIT_BASE_BRANCH

# Create worktree with new branch
git worktree add -b <branch-name> <worktree-path> $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH

# Example:
git worktree add -b feat/privatelink-karpenter ../hs-privatelink $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH

Without worktree (same repo):

# Fetch latest
git fetch $GIT_UPSTREAM_REMOTE $GIT_BASE_BRANCH

# Create and checkout new branch
git checkout -b <branch-name> $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH

# Example:
git checkout -b fix/bug-123 $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH

Branch Naming Conventions

Use conventional prefixes:

feat/<description> - New features
fix/<description> - Bug fixes
docs/<description> - Documentation
refactor/<description> - Code refactoring
test/<description> - Test additions
chore/<description> - Maintenance tasks

Commit Changes

Always follow the git-commit-format skill for commits.

Stage changes:
```
git add <specific-files>
```
Check what's staged:
```
git status
git diff --cached
```

Commit with proper format:

git commit -m "$(cat <<'EOF'
<type>(<scope>): <description>

[optional body]

Signed-off-by: <name> <email>
Commit-Message-Assisted-by: Claude (via Claude Code)
EOF
)"

Validate commit message:
```
make run-gitlint
```

Push to Remote

First push (set upstream):

git push -u $GIT_FORK_REMOTE <branch-name>

Subsequent pushes:

git push

Force push (after rebase):

# Always use --force-with-lease for safety
git push --force-with-lease

Sync with Upstream

# Fetch latest from upstream
git fetch $GIT_UPSTREAM_REMOTE $GIT_BASE_BRANCH

# Rebase current branch on base branch
git rebase $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH

# If conflicts, resolve them, then:
git rebase --continue

# Push updated branch (force required after rebase)
git push --force-with-lease

Cleanup Worktree

# Remove the worktree
git worktree remove <worktree-path>

# Optionally delete the branch
git branch -D <branch-name>

# Prune stale worktree references
git worktree prune

List Worktrees

git worktree list

Quick Reference Commands

Task	Command
New worktree + branch	`git worktree add -b <branch> <path> $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH`
New branch (no worktree)	`git checkout -b <branch> $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH`
Stage all changes	`git add -A`
Stage specific files	`git add <file1> <file2>`
Check status	`git status`
View staged diff	`git diff --cached`
Commit	`git commit -m "<message>"`
Validate commit	`make run-gitlint`
Push (first time)	`git push -u $GIT_FORK_REMOTE <branch>`
Push	`git push`
Force push (safe)	`git push --force-with-lease`
Sync with upstream	`git fetch $GIT_UPSTREAM_REMOTE $GIT_BASE_BRANCH && git rebase $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH`
Remove worktree	`git worktree remove <path>`
Delete branch	`git branch -D <branch>`
List worktrees	`git worktree list`

Example Full Workflow

# 0. Load environment
source dev/claude-env.sh

# 1. Create new feature environment
git fetch $GIT_UPSTREAM_REMOTE $GIT_BASE_BRANCH
git worktree add -b feat/aws-privatelink-subnets ../hs-privatelink $GIT_UPSTREAM_REMOTE/$GIT_BASE_BRANCH
cd ../hs-privatelink

# 2. Make changes...
# ... edit files ...

# 3. Stage and commit
git add -A
git commit -m "$(cat <<'EOF'
feat(aws): add dynamic subnet discovery for privatelink

Implement subnet discovery from Karpenter EC2NodeClass resources
to ensure PrivateLink VPC Endpoints have ENIs in all required
availability zones.

)"

# 4. Validate
make run-gitlint

# 5. Push to fork
git push -u $GIT_FORK_REMOTE feat/aws-privatelink-subnets

# 6. Create PR via gh cli
gh pr create --title "feat(aws): add dynamic subnet discovery for privatelink" --body "..."

# 7. After PR merged, cleanup
cd ../hypershift
git worktree remove ../hs-privatelink
git branch -D feat/aws-privatelink-subnets

Notes

Always use --force-with-lease instead of --force for safety
Worktrees allow parallel development on multiple features
Each worktree shares the same git repository but has its own working directory
Run git remote -v to verify remote configuration
Configure your fork remote in dev/claude-env.sh by setting GIT_FORK_REMOTE
