The skill does what it advertises, but it can send private conversation, calendar, memory, and meeting-note content to Telegram without a clear per-send consent or local-only option.
Install only if you are comfortable sending generated mindmaps, including possible meeting notes, priorities, calendar-derived context, or memory-derived context, through Telegram. Use a dedicated Telegram bot token limited to the intended chat, verify chat_id carefully, avoid regulated or confidential material unless Telegram is approved for that use, and prefer preinstalling a pinned Mermaid CLI instead of relying on runtime npx installation.
