Read a Knowledge document (Parse from document): its pages are read as the instruction says (one given here is written on the document first), split into passages, the questions and answers extracted (model calls metered as drafts), each compared with Knowledge: new, already_there, says_otherwise; a document read before compares with its own answers first. The record rides result.parse and waits (get_agent_source_parse) for apply_agent_source_parse. 409 source_reading while a parse runs.

Contract:

• MCP tool parse_agent_source, registry package mcp.unibox/agent_sources, mount unibox.knowledge.
