git-surgeon-cli 0.0.1

Surgical git history rewriting: author rewrite, message scrub, sensitive data removal, and more.

🔪 git-surgeon

Surgical git history rewriting: a modular CLI toolkit wrapping git-filter-repo.

Rewrite authors, scrub sensitive data, clean commit messages, flatten merges, and filter commits, all in a single pass with automatic backup & undo.

Features

Feature	Description
Message Scrub	Find-and-replace text in commit messages (literal or regex)
Blob Scrub	Remove secrets, emails, keys from file contents across all history
Merge Flatten	Linearize history by converting merge commits to single-parent
Commit Filter	Remove or keep commits matching specific criteria
Backup & Undo	Automatic git bundle backup + git-surgeon undo to restore
Dry Run	Preview every change before touching the repo
Interactive Wizard	Run git-surgeon with no args for guided setup
Config Persistence	Operations saved to .git-surgeon/config.toml (auto-gitignored)

Quick Start

pip install git-surgeon

or

uv add git-surgeon

Requires Python ≥3.13 and git on PATH.

WIP

Safety

Every git-surgeon run automatically creates a git bundle backup at .git-surgeon/backup.bundle before touching history.
Run git-surgeon undo to fully restore.
Use --dry-run on any command to preview without modifying anything.
