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.

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.

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.

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.
