squashing-history

What problem does it solve?

This Skill provides a safe, auditable method to rewrite a Git history by squashing all commits on the main branch into a single "Initial commit" while preserving code integrity, with a backup branch for rollback and explicit user confirmation before destructive actions.

Core Features & Use Cases

• Backup-first history rewrite: creates a timestamped backup branch to restore if needed.
• Integrity verification: verifies no code changes by diffing against the backup.
• User-controlled force push: requires explicit confirmation before pushing to origin/main.
• Applicability: ideal for public releases, simplifying contributor history, or removing sensitive data after prior edits.

Quick Start

Follow the Phase-based workflow: Phase 1 checks, Phase 2 creates backup, Phase 3 records state, Phase 4 soft-resets to first commit, Phase 5 creates a single "Initial commit", Phase 6 validates zero diffs, Phase 7 confirms readiness, Phase 8 force-push after consent, Phase 9 completes and documents rollback.
