What the Knowledge Base Tool Does
The Knowledge Base tool allows a Custom Agent to search and retrieve content from internal documents.
When enabled, the agent can:
Search documents within the selected Knowledge Base
Retrieve relevant excerpts
Use internal content in responses
If the tool is not enabled, the agent cannot access internal documents.
Connecting a Knowledge Base to an Agent
To connect a Knowledge Base:
Open the Custom Agent settings
In the Tools section, enable Knowledge base
Click Configure
Select a Knowledge Base from the dropdown list
Click Save Configuration
Save the agent
Once configured, the Knowledge Base status will show as Configured.
The agent will search only within the selected Knowledge Base.

Creating a New Knowledge Base
If the required Knowledge Base does not exist, create a new one.
To create a Knowledge Base:
Open the Knowledge Bases section
Click the dropdown and select Create New…
In Basic Info, provide:
Name
Slug (URL-friendly identifier, lowercase with hyphens)
Status (set to Active if the Knowledge Base should be used)
If needed, open the SharePoint tab and provide the required credentials
If applicable, configure the S3 Storage settings
Click Create
After creation, documents can be uploaded manually or synchronised from SharePoint.

Document Synchronization
Knowledge Bases process changes automatically.
The interface shows:
Last sync time
Sync status (for example, Success)
Only synced documents are searchable.
If documents were recently added, wait until synchronization is complete before testing the agent.
Restricting the Agent to Internal Documents
Enabling the Knowledge Base allows access to internal documents but does not automatically restrict responses to them.
To ensure document-based responses, include a rule in the system prompt such as:
Use only information from the connected Knowledge Base.
If the answer is not found in the documents, clearly state that the information is unavailable.
Without this rule, the agent may combine internal and general knowledge.
When to Use a Knowledge-Connected Agent
Use a Knowledge Base when:
Answers must come from internal policies or procedures
Document-based accuracy is required
Official documentation must be referenced
For general writing or external research, use the General Assistant instead.
