anony-git

A lightweight git wrapper that censors Personally Identifiable Information (PII) from git output before it reaches AI coding assistants.

The Problem

AI tools like Claude Code and Cursor routinely read git history for context — commit logs, diffs, and more. Commands like git log and git show expose author names and email addresses in their output, leaking PII to the model. This can feel intrusive, and creates friction for teams with strict data handling policies.

anony-git strips author information from git commands known to leak it.

How It Works

When anony-git receives a command that exposes author data, it injects the --oneline flag (if available), which limits output to the commit hash and subject line — no author names, no email addresses. If --oneline is not available (e.g. git blame, git shortlog) the output from git gets parsed and sanitized. All other commands are proxied as-is, so existing workflows are not disrupted.

Supported Commands

Command	Status
git log	Redacted
git show	Redacted
git blame	Redacted
git shortlog	Planned

All other commands pass through to git without modification.

Setup

1. Build from Source

git clone git@github.com:drewstaylor/anony-git.git
cd anony-git
cargo build --release

The binary will be located at ./target/release/anony-git.

2. Configure Your AI Tool

Claude Code

In your Claude Code terminal session, alias git to the anony-git binary:

alias git="~/YOUR_SYSTEM_PATH/anony-git/target/release/anony-git"

(Replace YOUR_SYSTEM_PATH with the path where you cloned the repo.)

Note: It is recommended to set this alias only within your AI tool's terminal session, and not to export it globally. This keeps the wrapper scoped to the AI's use of git, while your own terminal sessions continue to use the real git binary.

Cursor

Add the following to your Cursor settings.json:

{
  "git.path": "/absolute/path/to/anony-git/target/release/anony-git"
}

Replace the path with the absolute path to the binary on your system.

Settings file locations:

• macOS: ~/Library/Application Support/Cursor/User/settings.json
• Linux: ~/.config/Cursor/User/settings.json
• Windows: %APPDATA%\Cursor\User\settings.json

For a project-specific override, add git.path to .vscode/settings.json in the project root instead.

Note: Shell aliases (e.g. alias git=...) do not work for Cursor's built-in git features. The git.path setting is required. Unlike the Claude Code alias approach, this also affects Cursor's SCM panel, not just the integrated terminal — which means author information will be redacted from Cursor's source control UI as well.

Restart Cursor after saving the setting.

Roadmap

• git shortlog — groups commits by author; its core purpose is to display authors, so this will require a custom formatting strategy
