SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires git-filter-repo, and includes scripts (resource) components.

What problem does it solve?

Invalid submodule pointers in a parent repository history can break builds and hinder collaboration. This skill surgically repairs those pointers using a deterministic, safety-conscious protocol to restore valid references without compromising upstream history.

Core Features & Use Cases

  • Detect broken submodule pointers and identify the exact introduction commit.
  • Determine the Synchronization Horizon boundary to align parent mandates with submodule history.
  • Create a safety backup tag and perform a controlled pointer swap with guarded propagation.
  • Use cases include broken-pointer repair, historical realignment after submodule rewrites, and mandate auditing.

Quick Start

Run the repair engine to locate the invalid submodule pointer and surgically update history with a backup before patching.

Frequently Asked Questions about Git Submodule Pointer Repair

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I repair invalid git submodule pointers in parent repository history?▼

To repair invalid git submodule pointers, this skill identifies the exact introduction commit and surgically updates history. It uses a deterministic protocol to restore valid references without compromising upstream history.

Why do broken submodule pointers break builds and how can I fix them?▼

Broken submodule pointers break builds by pointing to non-existent commits. This skill fixes them by creating a safety backup tag and performing a controlled pointer swap with guarded propagation through history.

What is the Synchronization Horizon algorithm for git submodules?▼

The Synchronization Horizon algorithm aligns parent mandates with submodule history to determine the boundary for valid pointer realignment. It ensures historical consistency when repairing or rewriting submodule references.

How do I realign submodule history after a repository rewrite?▼

To realign submodule history after a rewrite, this skill determines the Synchronization Horizon boundary and propagates fixes through history with controlled rebasing. A safety backup tag is created before patching.

Do I need git-filter-repo to fix broken submodule pointers?▼

Yes, git-filter-repo is required as a dependency to fix broken submodule pointers. The repair engine relies on it to surgically update the parent repository history and propagate the corrected references.

Can I audit submodule mandates and detect when invalid pointers were introduced?▼

Yes, you can audit submodule mandates and detect invalid pointers. The skill identifies the exact commit where a broken submodule pointer was introduced and determines the correct Synchronization Horizon boundary for repair.
