Github Create Branch

GitHub — Create Feature Branch

Goal

Create a feature branch for a story using the configured naming pattern. Always checks if a branch already exists first (conflict layer 2 check).

Prerequisite Check

Check integrations.github in config. If missing: "Run github-connect first."

Step 1: Identify Story

Ask: "Which story is this branch for?" (accept S-ID, JIRA key, or title)

Load the story and extract:

• JIRA key: {JIRA-KEY}
• Story title slug: lowercase, hyphens, max 40 chars

Step 2: Compute Branch Name

Apply the configured branch pattern from config:

branch_name = "feature/{JIRA-KEY}-{slug}"
e.g., "feature/PROJ-42-add-user-authentication"

Step 3: Conflict Check — Branch Already Exists?

git fetch --all --quiet
git branch -a | grep -i "{branch_name}"

If found:

"⚠️ Branch {branch_name} already exists. This means someone may have already started this story. Run jira-conflict-detect for a full check before proceeding."

⏸️ STOP if conflict found. Ask: "Are you sure you want to proceed anyway?"

Step 4: Create Branch

Ensure we're on the default branch and up to date:

git checkout {default_branch}
git pull origin {default_branch}

Create the branch:

git checkout -b {branch_name}

Push to remote:

git push -u origin {branch_name}

Step 5: Update Local Story

Add to story frontmatter:

branch: "{branch_name}"
branch_created: "{date}"
branch_created_by: "{user_name}"

Completion

"✅ Branch created: {branch_name} Pushed to origin.

You're now on {branch_name}. Ready to implement with dev-story."

Ask: "Would you like me to update the JIRA ticket to 'In Progress' as well?"

If yes:

curl -s -X POST \
  "{jira_url}/rest/api/3/issue/{JIRA-KEY}/transitions" \
  -u "{email}:{api_token}" \
  -H "Content-Type: application/json" \
  -d '{"transition": {"id": "21"}}'

(Transition ID 21 is the standard "In Progress" transition. If it fails, list available transitions and ask user to pick.)
