I’d like to share **Luthn**, an open-source project for sharing project memory between AI agents.

Luthn connects to Codex and Claude Code through their hooks and MCP. After a turn, it collects a bounded capsule of the agent’s final response, classifies and redacts it, and makes permitted context available for later tasks. When a new task starts, the agent can retrieve a small context pack.

The project runs on infrastructure you manage, using Docker and PostgreSQL. It also includes a local operator console for reviewing sensitive-access requests. The goal is to let agents reuse project context while keeping private source material outside their default context.

I’m interested in feedback on both the design and the problem itself:
