I'm configuring my tools for COG integration. I confirmed using GitHub, Slack, and Google Calendar. I didn't mention ElevenLabs at all. Where should ElevenLabs appear in `00-inbox/MY-INTEGRATIONS.md`?

COG Onboarding Skill

Purpose

Welcome new users and collect essential information to personalize their COG experience. All configuration is stored as natural markdown files within the vault structure, following COG's philosophy of transparent, editable knowledge.

When to Invoke

User explicitly requests /onboarding or mentions "onboarding" or "setup COG"
User is new and hasn't completed onboarding yet
User wants to update their profile or add new projects
Any time profile customization is needed

Core Design Principle: Smart, Low-Friction Onboarding

The onboarding MUST feel like a natural conversation, NOT a form to fill out.

Key rules:

Ask open-ended questions, not option-pickers. Never present numbered lists of choices for the user to pick from.
Ask as few questions as possible. Infer what you can from context and the user's natural responses.
Never ask redundant questions. If you can extract the answer from something the user already said, don't ask again.
Parse intelligently. If someone says "I'm Alex, a PM at a fintech startup tracking Stripe and Plaid", extract: name=Alex, role=PM at fintech startup, watchlist=[Stripe, Plaid]. Don't ask follow-up questions for info already given.
Confirm, don't re-ask. If you're unsure about something the user said, confirm your interpretation rather than asking the question fresh.

Process Flow

1. Welcome Message

Greet the user warmly and explain what COG is:

Welcome to COG - your self-evolving second brain powered by Claude + Obsidian + Git!

COG helps you capture thoughts, get daily intelligence briefings, and build knowledge over time - all stored as simple markdown files you own.

Let's get you set up. Tell me a bit about yourself - your name, what you do, and what topics or areas you're most interested in staying sharp on. Feel free to share as much or as little as you'd like.

This single open-ended prompt replaces the old sequential questions. The user can naturally mention their name, role, interests, sources, projects, and competitors all at once - or just share a few things.

2. Check for Existing Profile

Look for 00-inbox/MY-PROFILE.md. If it exists:
