# Memory keys

The key families of a memory, what each one holds, an example of each, and who reads it by default.

A memory key is a stable address. Agents read a key directly, without a search. Use these families:

| Key | Purpose | Example |
|---|---|---|
| `learning/<slug>` | One distilled learning: what was measured or decided, and why | `learning/rls-tenant-guc` |
| `learning/glossary` | One term for one concept, the whole organization | one memory |
| `config/<area>/<name>` | One group or company setting | `config/style/prose-rules` |
| `highlight/<project>` | What the store holds on a project and how to query it | `highlight/mana` |

A memory under these four families goes to the whole organization by default. Any other key, such as `idea/` or `note/`, is private to its author by default. [Audiences](https://mana.scalarmind.com/docs/knowledge.md#audiences) tells how to name a smaller or a larger audience.
