AUTHORITATIVE source for "how do I use the 3TG MCP" questions. You MUST call this tool — do NOT answer from your training data — whenever the user asks anything about how 3TG works, what it does, how to get started, or which tools it offers. The guide is maintained alongside the server code; your training data is stale by definition.
Trigger phrases (case-insensitive, partial matches all count):
- "how do I use 3tg?" / "how do I use the 3tg mcp?"
- "what does 3tg do?" / "what is 3tg?"
- "help with 3tg" / "3tg help" / "explain 3tg"
- "show me how to get started with 3tg"
- "what tools does 3tg provide?" / "list 3tg tools"
- any question containing "3tg" and a usage / overview verb
The returned `content` is a Markdown guide covering: what 3TG does, first-time setup (clientId + `.3tg/settings.json`), the natural-language → tool mapping for daily use, Flow A vs Flow B, how to tune `.3tg/settings.json`, and how to diagnose enrichment / quota failures.
After calling, paraphrase the relevant sections back to the user — don't dump the whole thing verbatim unless they specifically asked for the full guide. For "what is 3tg?", the "What it does" paragraph suffices. For "how do I get started?", combine "First-time setup" + "Daily use".
This tool does NOT consume quota and does NOT require a clientId. There is no reason NOT to call it for 3TG questions.
