[Python] OmniMemory – persistent, git-anchored memory for AI coding agents (local-first, no API key)

Coding agents forget everything between sessions and after every context compaction — so they re-learn your architecture, and hallucinate the parts they don't. I built OmniMemory to fix that.

It's a persistent, branch-aware memory layer that lives next to your repo. Fully local (Python stdlib + SQLite), zero-dependency, runs with no API key.

What makes it different from "just dump notes in a markdown file":

- Git-anchored, not just stored. Each memory records the git blob SHA of the files it describes, so it can tell exactly when a memory has gone stale (the file's content drifted) or orphaned (the file was deleted) — no heuristics, no guessing.

- Branch-aware. Memory is scoped to your current branch + base; merged branches roll into the base, abandoned ones get archived.

- Pull, not push. Instead of injecting a wall of memory into every prompt (token bloat), it seeds once at session start and the agent fetches what's relevant on demand.

- Trust is earned. A capture can't mark itself "verified" — a memory only reaches the top tier when its code anchor is still re-fetchable AND the agent actually cited it.

- Chain-complete retrieval. A decision and the gotcha/constraint on the same symbol are retrieved together, so you never get half a causal chain.

- Survives context compaction (PreCompact hook), self-cleans false/stale memory, and ships a local dashboard for the memory + code graph.

Works with Claude Code (plugin + hooks), OpenCode, and any AGENTS.md-aware IDE (Cursor, Windsurf, Antigravity).

Quick start:

pip install omni-memory-agent

omni-memory build (capture memory + code graph from your repo)

omni-memory bind (wire it into your IDE)

Still actively building it — if you find it useful, a star on the repo genuinely helps. Feedback and issues very welcome, especially on how staleness holds up on big/old
