name	gh-subrepo
description	Stateful bidirectional sync for subtree directories using git-subrepo. Sync monorepo subdirs with standalone GitHub repos and graduate projects from lab to production.

gh-subrepo

Overview

This skill manages standalone repositories from inside monorepo subdirectories using git-subrepo.

It is designed for the write/write topology where:

• You work in 40-code/41-subtrees/<name> inside the monorepo
• Collaborators work directly in standalone GitHub repositories

git-subrepo reduces custom sync logic by tracking per-subdir sync metadata in .gitrepo files.

Sub-skills

You must load the appropriate sub-skill from sub-skills/ based on user intent.

• sub-skills/subrepo-status.md

  • Diagnose subrepo setup and sync health
  • Triggers: subrepo status, check subrepos, subrepo health

• sub-skills/sync.md

  • Pull and push changes for an existing subrepo
  • Triggers: sync, pull from remote, push to remote, subrepo pull, subrepo push

• sub-skills/graduate.md

  • Move a lab project into 41-subtrees/ and initialize it as a subrepo
  • Triggers: graduate, move to production, publish new project

Process

• Determine user intent
• Load the matching sub-skill
• Execute the sub-skill process
• Verify expected outcome

Resources

• scripts/subrepo-status.sh: lightweight status helper for 41-subtrees/
• sub-skills/: workflow-specific instructions

Conventions

• Every directory in 40-code/41-subtrees/ is a candidate project
• Note: Active subrepos during migration may be in 40-code/415-subrepos/
• A project is subrepo-managed when <subdir>/.gitrepo exists
• Remote naming should still follow remote-<dirname> for compatibility with existing tooling
• Keep the main branch index unstaged on monorepo main
• Get user approval before pushing to remotes
