git-ghost: I summoned the ghost of my first commit with a local Gemma model

Description and use

git-ghost lets developers summon their first author using a local Gemma model to receive a fact-based narrative of a repository’s origins, evolution, and advice, all without sending data to the cloud.

Problem

Developers want to reflect on the earliest state of a repository without exposing commit history to external services.

Outcome

git-ghost enables developers to hear a nostalgic, fact-based story of their project’s earliest days, providing insight and actionable advice without external data exposure.

Workflow

• 1. Run python git_ghost.py <repo_path>
• 2. git_ghost.py executes git log to fetch first and latest commits
• 3. It streams the commit data to a local Ollama instance via /api/chat
• 4. The Gemma model generates a three-part narrative based on the commit facts
• 5. The output is printed to the terminal and fades back into .git

Evidence

git-ghost is a tiny command-line tool that summons the ghost of your past self from the oldest commits of any git repository.

Source

It reads your first commits (the memories) and your latest commits (the living developer), then lets Gemma, an open-weight model running locally through Ollama, speak as the ghost of the developer you used to be.

Source

The whole tool is one Python file with zero dependencies: git log through subprocess, and a streaming call to the local Ollama /api/chat endpoint with urllib.
