| Term | What it is |
|---|---|
| Knowledge base | The retrieval corpus. Documents the agent searches to ground an answer. Two words, never one. |
| Data source | Where knowledge base content comes from: a file, a URL, or a synced integration. |
| Variable | A named slot of project state an agent reads and writes during a conversation. |
| Secret | A credential stored for the agent to use without exposing it in a prompt or a function. |
| Persona | A saved set of traits used to simulate a particular kind of user when testing. |
| PII redaction | Stripping personal data from what gets stored. |
| Document | One source inside the knowledge base: a file, a page, or a synced record. Retrieval returns passages from documents, not whole documents. |
Knowledge and data
The knowledge base, data sources, variables, secrets and redaction: what an agent reads, writes and protects while a conversation runs.
