Git Environment

A Git workflow for HyperShift development environments. Git is a tool for tracking code changes; this guide covers branches, worktrees, commits, and pushing changes to a remote repository.

In plain words
What is it for?
Creating feature branches or worktrees, fetching the project base branch, committing changes in the expected format, and pushing work to a fork or upstream remote.
Why use it?
It standardizes how developers create isolated work areas and keep changes based on the correct branch. It also provides the project-specific remote and branch settings needed for contributions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Git Environment scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

  1. Stage changes:

    git add <specific-files>
    
  2. Check what's staged:

    git status
    git diff --cached
    
  3. 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
    )"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Git Environment is a skill published in the GitHub repository openshift/hypershift (538 stars, last pushed 2d ago), licensed Apache-2.0. It adds 28 tokens to every session and 1,509 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
