In the “Create a Bot User” step, the instructions go straight to “Reset Token” but don’t include creating the bot user first (the Developer Portal typically requires clicking “Add Bot” before a token exists). Add the missing “Add Bot” step (or clarify that a bot user must exist) to avoid readers getting stuck on a page with no token to reset.

Suggested change

	2. Click "Reset Token" to generate a new bot token
	3. Copy and save this token securely — you won't be able to see it again
	2. Click "Add Bot" to create a bot user for your application, and confirm any prompts
	3. Once the bot user exists, click "Reset Token" (or "View Token" / "Regenerate") to generate a new bot token
	4. Copy and save this token securely — you won't be able to see it again

The keywords include telegram, but this page doesn’t mention Telegram and the “Available Interfaces” section doesn’t link to a Telegram interface. Consider removing telegram from keywords (or adding the corresponding Telegram interface card/link) so search/SEO metadata matches the actual content.

Suggested change

	keywords: [interfaces, a2a, ag-ui, slack, discord, whatsapp, telegram, protocols, integration]
	keywords: [interfaces, a2a, ag-ui, slack, discord, whatsapp, protocols, integration]

The “Quick Start” snippet builds app = agent_os.get_app() but doesn’t show how to actually run/serve it. Add a minimal if __name__ == "__main__": ... (or an explicit agent_os.serve(...) / uvicorn command) so the quick start is runnable like the other interface overviews.

Suggested change

	app = agent_os.get_app()
	app = agent_os.get_app()
	if __name__ == "__main__":
	import uvicorn
	uvicorn.run(app, host="0.0.0.0", port=8000)
