# Knowledge and access Memory keys, standing instructions, audiences, and sensitivity levels. ## What gets recorded An agent stores a memory when you ask it to remember a statement. Mana keeps the exact statement as evidence, the memory, and its origin in one transaction. A repeated request stores nothing twice. A changed statement under the same key becomes a new revision; the earlier revision stays readable in the history. ## Memory keys A memory key is a stable address. Agents read a key directly, without a search. Use these families: | Key | Purpose | Example | |---|---|---| | `learning/` | 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//` | One group or company setting | `config/style/prose-rules` | | `highlight/` | What the store holds on a project and how to query it | `highlight/mana` | ## Standing instructions When a client connects, Mana hands it the active `highlight/*`, `learning/glossary`, and `config/*` memories that you are allowed to read. The agent sees your organization's conventions before its first tool call. The text is bounded; when a key is omitted for size, the instructions name it. Any agent can ask for the same text again during a session. ## Audiences Every memory has an audience. The default is private: only its author reads it. Ask the agent to share with the whole organization, or with one part of it, at the moment you record the memory. | Audience | Who reads it | |---|---| | private | you | | tenant | every member of the organization | | `org:` | the people under one node of the organization tree, such as `org:research/lng` | An audience never widens on its own. Only the author, or a person with a wider grant, changes it. ## Sensitivity levels Each memory also has a level: `public`, `internal`, `confidential`, or `restricted`. A member's agent reads up to `internal`. An admin's agent reads up to `confidential`. `restricted` is for people; no agent grant reaches it. A deterministic label is set at write time from the audience and the level. An agent does not decide the level. A wrong level or audience is corrected with the same key and a reason. Mana keeps the prior revision and records who changed what.
