Memory

Every crew member keeps a memory: a running report of what it did, what it found and what it learned. Memory is what makes a crew better at your project every week.

Three layers

Layer	Lives	Holds
Thread	One conversation	The details of the current task
Personal	One model, all tasks	Its report: discoveries, patterns, lessons
Shared	The whole crew	Lessons promoted from personal memory

The report

Each model writes short, dated entries tagged as onboarding, discovery, lesson or pattern. You can read, edit or delete any entry from the model's profile.

Sharing a lesson

When a model records a lesson, Lumen suggests who else should know. Accept, and the lesson moves to shared memory and appears in the reports of the chosen members.

"Staging deploys need manual approval" — learned once by Claude, shared with three crew members.

Memory across models

Memory belongs to the crew member, not to the model behind it. If you switch a member from GPT to Claude, the report stays. The new model reads it on its first task.

Privacy

Memory is stored locally in your workspace folder under .lumen/memory. It's sent to a model only as part of that model's own context.
