git-submodule
Version-control external repositories within a main project using Git submodules.
- Add, update, and remove submodules with commands for locking specific commits, branches, or tags
- Clone repositories with submodules using
--recursiveor manual initialization and update steps - Batch operations across all submodules via
git submodule foreachfor pulling, checking status, and branch management - Nested submodule support with recursive initialization and updates for complex dependency hierarchies
- Troubleshooting guidance for detached HEAD states, permission errors, dirty submodules, and reference mismatches
Git Submodule
When to use this skill
- Including external Git repositories within your main project
- Managing shared libraries or modules across multiple projects
- Locking external dependencies to specific versions
- Working with monorepo-style architectures with independent components
- Cloning repositories that contain submodules
- Updating submodules to newer versions
- Removing submodules from a project
