Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• add_document_from_urlAdd a document from a URL

  Fetch a public web page and add it to the corpus so it can be answered from later. Ingestion is asynchronous — the document is not answerable the instant this returns. The server refuses private and internal addresses, so this cannot be used to reach anything on its network.

• ask_documentsAsk the documents

  Answer a question from the organisation's own documents, with citations. Returns the exact passages the answer was written from. Use this for anything about internal policy, runbooks, handbooks, contracts or product documentation — anything the user's organisation wrote down. If nothing in the corpus supports an answer this reports that rather than guessing: treat 'not found' as the real answer and say so, do not fall back on general knowledge and present it as the organisation's policy.

• forget_sessionForget a session

  Erase everything remembered for one conversation. Use when a session ends or the user asks to be forgotten. Durable memories about a subject are not affected.

• list_documentsList documents

  List the documents available to answer from, with their ingestion status. Use this to tell the user what the system actually knows about, or to check whether something they uploaded has finished processing.

• list_namespacesList namespaces

  List the slices the document corpus is divided into, with how many documents each holds. Use this before ask_documents when a question clearly belongs to one area and you want to avoid another area answering it.

• recallRecall from memory

  Retrieve what was previously remembered that relates to the current situation. Ranked by relevance, weighted by importance and decayed by age, so a recent statement outranks an old one saying the opposite. Worth calling at the start of a conversation with a returning user. This searches memory, not documents — use ask_documents for anything the organisation wrote down.

• rememberRemember something

  Record something worth carrying beyond this conversation — a stated preference, a durable fact about the user, a decision and its reason. Do NOT use this for things the documents already say, for anything the user would be surprised to find stored, or for the content of the conversation itself. Restating something already remembered is harmless: it updates rather than duplicating.
