What OpenTable would need to change

1Verify agents cryptographically instead of blocking them at the doorAccess · up to 23 pts

Your edge answers every non-browser client with a block or interstitial. Web Bot Auth (HTTP Message Signatures, RFC 9421) lets an agent prove who it is per request; Cloudflare, Akamai, AWS WAF and Vercel can verify it. Allow verified agents and keep challenging the rest.

# Cloudflare: Security → Bots → Verified bots → allow category "AI Agent"
# Or verify yourself: fetch the agent's key from
#   https://<signature-agent>/.well-known/http-message-signatures-directory
# and check the Signature / Signature-Input headers (tag="web-bot-auth")

2Stop disallowing identified user-directed agents in robots.txtAccess · up to 14 pts

You disallow 16 agents that act live for a person. Crawler rules (GPTBot, ClaudeBot) can stay; user-directed agents are the ones a customer sends.

User-agent: GoogleAgent-Mariner
User-agent: GoogleAgent-Shopping
User-agent: Manus-User
User-agent: MistralAI-User
User-agent: Devin
User-agent: Copilot

3Give agents a front doorProtocols · up to 12 pts

A Universal Commerce Protocol manifest for shopping, or an MCP server card for everything else. An agent that can call an API never needs to hold a customer's password.

4Publish llms.txtSurface · up to 8 pts

A short markdown map of what the site does, where the important pages are, and how to search or check out.

/llms.txt
# OpenTable
> One paragraph on what this site is for.
- [Products](/products): how to search and filter
- [Checkout](/checkout): steps and constraints

5Say your stance with a Content-SignalConsent · up to 3 pts

Two lines in robots.txt end the guessing game. ai-input covers agents reading pages on a person's behalf.
