Read static knowledge, rules, or instructions from a read-only block

Agent Knowledge Block

AI-generated

Summary

Returns a read-only knowledge block for each input item, so an AI Agent or downstream node can use static topic knowledge, rules, or instructions. Choose whether to include the full text or only block metadata.

Inputs

  • Block Name — Short name included in the response; defaults to default_knowledge.
  • Tool Description — Description for the AI Agent about when to use this tool. The node declares this field, but its execution does not use it to build the returned data.
  • Knowledge Text — Static knowledge, rules, or instructions to return. Defaults to an empty string.
  • Output Mode — Full Text returns the knowledge text and counts; Summary Metadata Only returns block metadata and an availability message. Defaults to Full Text.

Output shape

A list of items, one per input item (or one item when there is no input), each containing a JSON object.

Responses include blockName, character and word counts, source: "agent_knowledge_block", and readOnly: true. Full Text mode also includes knowledgeText; Summary Metadata Only includes a message that the block is available. Empty knowledge text returns an empty knowledgeText and a warning regardless of output mode. With Continue On Fail enabled, execution errors produce an item containing an error field.
