git-memory 0.1.1

Dual-layer ChromaDB + Mem0 Git commit index for Claude Code

git-memory

Dual-layer semantic index over Git commit history for Claude Code.

Layer	Purpose
ChromaDB	1 document/commit, cosine similarity, metadata filters — fast, authoritative facts
Mem0	LLM-extracted context, cross-session learned interpretation — the why layer

Install

pip install git-memory

No external services required — works out of the box with three embedding options:

Mode	Setup	Cost
Ollama (default)	ollama pull nomic-embed-text	Free, fully local
sentence-transformers	pip install "git-memory[sentence-transformers]"	Free, fully local, no Ollama
OpenAI	pip install "git-memory[openai]" + OPENAI_API_KEY	~$0.0001/commit

Quick start

# 1. Index your repository
git-memory index --repo-path /path/to/repo --user-id my-repo

# 2. Install Claude Code skills + MCP config
git-memory install --repo-path /path/to/repo --user-id my-repo

# 3. Restart Claude Code — then use /git-memory-search, /git-memory-debug etc.

MCP tools

Tool	Description
search_git_history(query)	Semantic search over commit history
latest_commits(limit)	N most-recent indexed commits
commits_touching_file(filename)	All commits that modified a file
bug_fix_history(component)	Bug/security fixes for a component
architecture_decisions(topic)	Refactors, migrations, design decisions

CLI

git-memory index    --repo-path . --user-id myapp   # bulk index
git-memory serve                                     # start MCP server (stdio)
git-memory status   --repo-path .                    # show coverage
git-memory install  --repo-path . --user-id myapp   # install plugin
git-memory store    HEAD                             # store single commit (hook)

Configuration

All settings via environment variables:

Variable	Default	Description
GIT_MEMORY_REPO_PATH	.	Repository to index
GIT_MEMORY_USER_ID	git_memory_system	Mem0 namespace (use per-repo names)
GIT_MEMORY_CHROMA_DIR	~/.cache/git_memory/chroma_commits	ChromaDB storage path
GIT_MEMORY_EMBED_PROVIDER	ollama	Embedding backend: ollama, openai, sentence-transformers
GIT_MEMORY_EMBED_MODEL	(provider default)	Override embedding model name
GIT_MEMORY_LLM_MODEL	(provider default)	Override LLM model name (Mem0 layer)
OPENAI_API_KEY	(empty)	Enables OpenAI embeddings + LLM automatically
MEM0_API_KEY	(empty)	Use Mem0 cloud instead of local inference
OLLAMA_URL	http://localhost:11434	Ollama endpoint

Works great alongside GitNexus

• GitNexus answers what calls what (structural, live code)
• git-memory answers why it was written that way (historical, commit-level)
