Terms in this definition
- File search tool
Gives an agent hybrid search over files users upload: they are parsed, split into 800-token chunks and embedded in a vector store. For an already curated index, use a different tool.
- Agent
A specialised form of Microsoft Copilot set up for one particular job, pairing instructions with knowledge and skills. You can create one in Copilot Studio, SharePoint or Agent Builder, and administrators control them from the Microsoft 365 admin center.
- Container
Something that groups data. Blob Storage containers sit inside a storage account and hold blobs much as folders hold files; Cosmos DB containers hold items and set the scope for partitioning and throughput.
- Capacity
A reserved block of compute for a tenant whose size is fixed by its SKU; Fabric F SKUs express it in capacity units (CUs). Workspaces assigned to it unlock features like Copilot, and from F64 upwards people with free licences can view Power BI content.

The field on an agent or conversation holding the data tools need, for example files for code interpreter or vector store IDs for file search. Tool definitions belong in tools instead.
