0.91.0

Added

• The agent skill asks for two or three searches in other words before reporting no answer, covering
  paraphrases and language changes without a separate query-expansion model.

• Meeting search exposes every shared selector, including meeting/person/identity/event/series ids,
  tags and topics. The guide explains Memo's explicit stored-account scope and why calendar verification
  and zm's extra semantic-search flags differ.

• memo mail add <account> <address> checks the explicit Himalaya account and matching configured email
  before saving it. mail check <account> repeats the local checks; neither command chooses a default account
  or opens the mailbox. Use --kind imap and repeated --folder for other IMAP providers.

• memo models text download <model> downloads and checks the shared search model, through cli-core's
  downloader. Sync, search and setup instructions now point to memo models text download e5-small.

• MCP exposes the command tree, including writes, with generated command names alongside all 37 existing
  tools. Open cited notes with notes_show, stored messages and emails with messages_show, and tags with tags_list.
  Source-folder and mail-rule changes need mcp.authority (denied by default). Meeting findings decisions
  and selected annotation restore each need their own explicit permission. agent_decisions still applies.

• Saved dotted permissions and mcp --permission key=level limit tools. Server overrides can only tighten
  saved levels; locks and permissions are checked before every call. MEMO_READ_ONLY removes writing tools.

Fixed

• The shared mail-import hint names --only mail, included with cli-core 0.404.0.
• cli-base is pinned at 0.50.3, matching cli-core's required vocabulary. MCP server/client are pinned at 2.3.0.
• Install instructions name npm 11.17's allowScripts warning and npm 12's blocked scripts, explain the
  package-specific approval command, and keep memo skill install --for all explicit.
• The introduction describes file writes accurately: notes edit can change a source note, notes export
  writes files, and explicit Gmail Trash and restore commands need --yes.
