What Lowe's would need to change

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

Your edge answers ChatGPT-User, Claude-User, Perplexity-User, GoogleAgent-Mariner 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")

2Give 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.

GET /.well-known/ucp
{ "ucp": { "version": "2026-01-23",
  "services": { "dev.ucp.shopping": [{ "transport": "rest", "endpoint": "https://www.lowes.com/api/ucp/v1" }] },
  "capabilities": { "dev.ucp.shopping.checkout": [ … ] } } }

# or
GET /.well-known/mcp.json
{ "name": "Lowe's", "endpoint": "https://www.lowes.com/mcp", "transport": "streamable-http" }

3Publish 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
# Lowe's
> One paragraph on what this site is for.
- [Products](/products): how to search and filter
- [Checkout](/checkout): steps and constraints

4Use semantic landmarksSurface · up to 5 pts

main, nav, header, footer and labeled forms. Everything an accessibility audit already asks for.

<header>…</header>
<nav aria-label="Primary">…</nav>
<main>…</main>
<form aria-label="Site search"><label for="q">Search</label><input id="q" name="q"></form>

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.

User-Agent: *
Content-Signal: search=yes, ai-input=yes, ai-train=no
