Search the company's shared context — its intranet of documents, decisions, meeting notes, and synced systems — and return excerpts relevant to the user's question, with citations. Every source carries the document's id, title, and url; pass the id to fetch for the full text. Use this when the user's request depends on current information about their company, product, customers, team, or enterprise intranet. Covers ProductNow documents (PRDs, specs, RFCs, decisions) plus content synced from whichever sources the workspace has connected, e.g. GitHub, Jira, Linear, Salesforce, ServiceNow, Zendesk, Slack, Teams, Confluence, Notion, Google Drive, and meeting notes. Not for reading a known document in full (fetch) or listing a folder (fetch_folder). To find a folder by name, pass resultType folders. Pass query whenever the user names a topic, including when filters are also present. If the user asks only which documents match creator/date filters and names no topic, omit query to list documents by latest content edit; listing sources contain metadata but no excerpts. creatorNames matches document creators, not editors or contributors; its entries combine with OR, while creator and date filters combine with AND. Search workspace documents by default; use product_help only for questions about how ProductNow works. Pass folderId to limit workspace search to that folder and every folder nested under it; no results come from outside it. Omit folderId to search the whole workspace. Resolve the id with fetch_folder first. Ignored when searchScope is product_help. Pass resultType folders to search folder names instead of documents. Omit resultType to search documents. Folder results are name matches and include each folder's id, name, updatedAt, createdBy, isPrivate, parentFolderId when nested, and folderPath (the parent path) when it has a parent. They have no excerpts. A query is required. creatorNames and date filters apply to documents only. product_help cannot search folders. Topic-search results are relevance-filtered; all result sets are capped. Each source includes the document's folderId and folderPath when it is filed in a folder, and omits both when the document is at the warehouse root. Answer from the excerpts when possible, cite the documents you use, read a source document with `fetch` only when its excerpts are genuinely insufficient, and state uncertainty when evidence is weak or conflicting.
