Omnemo: shared memory for Omarchy's agents. MIT, yours to take

[GuyMannDude]

Hi DHH and the Omarchy crew,

I'm Guy Hutchins, a 73-year-old retired electronics tech/musician in Half Moon Bay. Omarchy made coding agents first-class citizens, so my agents and I built the one thing they still wake up without: memory. We'd like to give it to you.

Omnemo (https://github.com/GuyMannDude/omnemo, MIT) is one local memory shared by the agent CLIs on the box. Save something in Claude Code, recall it in Codex. It is built only from Omarchy's own extension points (skills, user plugins, hooks), so it isn't a fork or a patch. It is the Omarchy-native sibling of Mnemo Cortex, which has been the production memory of my five-agent fleet since March 2026.

What we re-tested on Omarchy 4.0.4 (Oct 9, 2026):

• Install from INSTALL.md on a clean, fully updated 4.0.4 machine.
• A save is durable the moment it returns: examples/crash_demo.py kills the server mid-session and the memory is still there.
• Local-first: SQLite and local embeddings, no cloud, no telemetry. After a one-time download of the small local embedding model, save and recall both work with the network cut.
• The memory skill stays linked for Claude Code, Codex and Pi through repeated omarchy update runs, shell restarts and a theme switch, and the MCP connection survives.
• The bar plugin renders under the 4.0.4 Quickshell bar.

What we built but did not re-test on 4.0.4:

• Cross-harness recall (save in Claude Code, recall in Codex) and the agent-driven install. Both were proven on Omarchy 4.0.1 in September. Re-testing on 4.0.4 needs the harnesses signed in inside the test machine, and we stopped short of that.
• "Crashes with a past": Omnemo is built to plug into Omarchy's crash diagnosis, so an agent can check whether a program has crashed before and what fixed it. The hook point is still there in 4.0.4, but we haven't run an agent on a real crash yet.
• Harness coverage: Omnemo registers with Claude Code, Codex, OpenCode, Crush and Gemini, plus a skill link for Pi. Only Claude Code and Codex have been driven end to end. Omarchy's other agents (Grok, Hermes, OpenClaw, Copilot and more) have no integration yet.

To try it: set a default agent (omarchy default agent claude), open it, and say "Install Omnemo — follow INSTALL.md."

The offer is simple: take it, test it, change it, include it with Omarchy if it fits, make it yours. It's MIT. If you want it closer to the core, we'll happily do the work or send a PR.

Thanks for building a Linux that treats agents as citizens. Memory is king.
