Fix it with Claude Code
Each failed check below has a ready-made prompt tailored to this scan's findings. Run it in Claude Code from your site's repository.
✗WAF/CDN blocks 1 agent despite robots.txt allowing themshow prompt
My e-commerce site is sennheiser.com. Our robots.txt does not block these AI agents, but live HTTP tests show our WAF/CDN returns 403s or challenge pages to them: - Bingbot (Microsoft — Copilot / Bing) This means our stated policy (allow) and our enforcement (block) disagree, and AI assistants silently fail on our store. In this repository and our infrastructure config: 1. Search for bot-management or firewall configuration (Cloudflare rules in code/terraform, vercel.json, middleware that filters user-agents, security headers config). 2. Where we control it in code, add allowlist entries for the user-agents above — scoped to product, category, and content pages only; keep protections on /cart, /checkout, /account, and admin routes. 3. Show me the diff, and flag any rule you find that blanket-blocks "bot-like" traffic. 4. If the blocking happens in a dashboard we don't keep in code (e.g. Cloudflare Super Bot Fight Mode, DataDome, PerimeterX), tell me the exact product setting to change and what to set it to. After deploy, verify with: curl -A "GPTBot/1.0" -I https://sennheiser.com/ (expect 200, not 403).
✗No Schema.org Product markupshow prompt
My e-commerce site is sennheiser.com. A scan found JSON-LD on the site but no Schema.org Product markup, so AI shopping agents can't reliably read our product names, prices, availability, or images. The site runs on magento, so prefer that platform's idiomatic way of serving these files/markup (theme templates, app settings, or metafields) over hand-rolled middleware where it exists. In this repository: 1. Find the product page template/component and add a JSON-LD <script type="application/ld+json"> block with Schema.org Product markup: name, description, image, sku, brand, and an Offer with price, priceCurrency, availability (use schema.org/InStock | OutOfStock), and url. Populate every field from our real product data — no placeholders. 2. Add an Organization JSON-LD block to the base layout (name, url, logo) if missing. 3. If we have category/listing pages, add ItemList markup referencing the product URLs. 4. Show me one fully rendered example of the JSON-LD for a real product, then validate the shape against Google's Rich Results requirements for Product and fix any warnings you can detect statically. Verify after deploy with https://search.google.com/test/rich-results on a product URL.
✗No machine-readable product feedshow prompt
My e-commerce site is sennheiser.com. A scan found no machine-readable product feed, which feed-based AI shopping agents (ChatGPT Shopping, Klarna, Google AI Mode) rely on. The site runs on magento, so prefer that platform's idiomatic way of serving these files/markup (theme templates, app settings, or metafields) over hand-rolled middleware where it exists. In this repository: 1. Determine where product data lives (database models, CMS, platform API) and add a product feed endpoint — Google Merchant–compatible XML (RSS 2.0 with the g: namespace) at /feeds/products.xml, or JSON if that's more idiomatic here. 2. Include per item: id, title, description, link, image_link, price with currency, availability, brand, and gtin/mpn when we have them. 3. Paginate or stream if the catalog is large; cache for ~1 hour. 4. Link the feed from robots.txt or a <link rel="alternate"> in the layout, show me the diff, and print the first two feed items rendered from real data.
