github.create_child_pr

Goal

• Given the current <SRC> Git branch, write instructions to build a child PR on a new <DST> branch

Workflow

Find the Next Branch Name

• Find which branch name is next available:

  > i git_branch_next_name
  Found highest number '3' in all branches, next is '4'
  branch_next_name='HelpersTask1273_Get_Mac_tests_to_pass_4'
  

Create the Instructions File

• Create a file plan-pr_merge.txt with instructions to:
  • Create a <DST> branch (e.g., HelpersTask1273_Get_Mac_tests_to_pass_4)
  • Copy the files needed to merge PR2 from github_PR_plan.md from the current branch to the target branch
  • Create plan-pr_commit_msg.txt with the description of what the PR does
  • Create plan-pr_title.txt with the one line G
  • Create plan-pr_pytest.sh with the tests that check the behavior of the PR
  • Add a comment for each phase, and make sure each command is correct
• In plan-pr_merge.txt and plan-pr_pytest.sh, state how they were generated, with this comment at the top of each file:

  # Generated by `.claude/skills/github.create_child_pr/SKILL.md`
  

Example

• Example commands to build a pr_merge.txt:

  > export SRC_BRANCH=HelpersTask1273_Get_Mac_tests_to_pass
  > export DST_BRANCH=HelpersTask1273_Get_Mac_tests_to_pass_6
  
  > git checkout master
  > git pull
  
  > i git_branch_create -b $DST_BRANCH
  > git checkout -b $DST_BRANCH
  
  > cat > pr_commit_msg.txt << 'EOF'
