Use Glean MCP tools to answer questions about company documents, internal wikis, policies, RFCs, design docs, people, teams, meetings, decisions, action items, email, calendar events, internal code, and the user's own work activity. Reach for this whenever the answer lives in enterprise systems rather than the local codebase or public web. Trigger phrases include "find the doc about", "what's our policy on", "where is the spec for", "who works on", "who owns", "find someone who knows", "what was decided in the meeting", "action items from", "search my email", "what did I work on last week", and "find the implementation in our repos". Don't use it for questions answerable from the local working directory, the public web, or generic programming knowledge.
