Optional improvements

These don't change your StackScope score but cover SEO, agent-readiness, security-researcher discoverability, and compliance items worth addressing.

Security

LOWAdd /.well-known/security.txt
WhyLets security researchers report vulnerabilities responsibly through a published contact channel.
WhereCreate /.well-known/security.txt with a Contact: email and Expires: date.

Email security

HIGHAdd an SPF record
No SPF TXT record found at the apex domain.
WhyWithout SPF and DMARC, receiving servers have fewer signals to reject spoofed mail using your domain.
WherePublish a TXT record at the apex like v=spf1 include:_spf.google.com ~all (replace the include: with your real sender, then end with ~all for soft-fail or -all for strict).
Learn more
MEDIUMMove DMARC from p=none to quarantine or reject
DMARC policy is p=none (monitoring only).
Whyp=none lets receivers log failures but still deliver spoofed mail. Real protection only kicks in at quarantine or reject.
WhereAfter reviewing a few weeks of rua= reports and confirming your real senders pass, change to p=quarantine (sends spoofs to spam) and then p=reject (blocks them outright).
Learn more
MEDIUMFix or remove the broken MTA-STS deployment
DNS record is published but the policy file couldn't be fetched.
WhyReceivers expect a policy whenever the DNS record exists. If they can't fetch it, they ignore MTA-STS entirely, so your deployment effort is wasted.
WhereEither fix the policy host (DNS, HTTPS cert, file path) or remove the _mta-sts TXT record so receivers stop checking.
Learn more
Why this matters & sources
Common causes: the policy host (mta-sts.{your-domain}) doesn't have a working A/AAAA/CNAME record, the host has no HTTPS certificate, or the path returns 404. The policy file must be at https://mta-sts.{your-domain}/.well-known/mta-sts.txt and contain a mode: line.

Page basics & SEO

LOWTrim your meta description to under 160 characters
Currently 252 characters: "Denker is the AI coworker that follows where you work. Agents see your screen, coordinate around shared context, and execute across your desktop. You direct from your cursor — no prompts to manage, no tools to switch — and results arrive where you are."
WhyGoogle truncates around 155-160 characters on desktop SERPs (less on mobile), so anything past that won't appear in the snippet.
WhereEdit your <meta name="description"> tag. Put the most click-worthy phrase first.
Learn more

Performance

MEDIUMSet width and height on your images
52 images render without explicit width/height.
WhyWithout intrinsic dimensions the browser can't reserve space before the image loads, so content jumps as it arrives (cumulative layout shift).
WhereAdd width and height attributes (or an aspect-ratio CSS rule). Framework image components set these for you.
Learn more
LOWServe right-sized images
43 images are downloaded at more than twice the displayed size.
WhyShipping a 2000px image into a 400px slot wastes bandwidth and slows loading, especially on mobile.
WhereResize to the displayed dimensions, or use srcset/sizes (or a framework image component) to serve per-viewport variants.
Learn more
LOWAdd alt text to your images
46 images have no alt attribute.
WhyScreen-reader users get no description, and search engines lose a signal about the image content.
WhereAdd a concise alt="..." to each image (an empty alt="" is correct only for purely decorative images).
Learn more

Agent / AI

LOWAdd Link response headers
WhyLets agents discover your sitemap, privacy policy, and docs without parsing HTML, which most lightweight agents skip.
WhereSet Link: response headers in your server config or framework middleware.

If a tip looks wrong (for example it says "add a consent banner" and you already have one) the detection's the bug, not you. StackScope sees what's public from the outside: HTTP response, rendered HTML, cookies, and DNS. We can miss vendors that load behind consent, are self-hosted, or use an install shape we haven't fingerprinted yet. Email [email protected] and we'll look into it.

Copy into Cursor, Claude, or ChatGPT

This prompt includes the detected stack and only the fixes StackScope found. It asks the AI to make concrete file-level changes, not a vague website review.

Score-affecting basics only. Ask your AI to handle these first; come back for the optional hardening once they're done.

Everything: score-affecting fixes plus optional email security, agent metadata, and best-practice items. Longer prompt, more for an "all in one" agent run.

I own https://www.denker.ai. StackScope (https://stackscope.dev) analysed it on 8 July 2026 and scored it 10.0/10 against their production-readiness checklist. Nothing score-affecting is currently outstanding, so use this prompt as a posture check rather than a fix list.

Tech stack StackScope detected on the site:
cloudflare, cloudflare-bot-management, cloudflare-dns, cloudflare-insights, framer-motion, google-ads, google-analytics, google-site-verification, google-tag-manager, hsts, http3, ionos-email, linkedin-insight, lucide-icons, nextjs, peerlist, posthog, product-hunt, react, resend, tailwindcss, three-js, vercel, youtube

Spot-check the stack above against current best practices: anything that looks deprecated, mis-configured, or like drift since the last deploy. If everything looks healthy, say so. Don't invent issues to fill the response.

I own https://www.denker.ai. StackScope (https://stackscope.dev) analysed it on 8 July 2026 and scored it 10.0/10 against their production-readiness checklist. Please help me apply the fixes below. This is a checklist, not a blocker list; Score-affecting fixes are the ones that move the number, Optional items are nice-to-haves with zero score impact that I can skip for an MVP.

Optional best-practice improvements (no score impact):
- [HIGH] Add an SPF record. No SPF TXT record found at the apex domain. Why: Without SPF and DMARC, receiving servers have fewer signals to reject spoofed mail using your domain. Where: Publish a TXT record at the apex like `v=spf1 include:_spf.google.com ~all` (replace the `include:` with your real sender, then end with `~all` for soft-fail or `-all` for strict). (https://www.cloudflare.com/learning/dns/dns-records/dns-spf-record/)
- [MEDIUM] Move DMARC from p=none to quarantine or reject. DMARC policy is `p=none` (monitoring only). Why: p=none lets receivers log failures but still deliver spoofed mail. Real protection only kicks in at quarantine or reject. Where: After reviewing a few weeks of `rua=` reports and confirming your real senders pass, change to `p=quarantine` (sends spoofs to spam) and then `p=reject` (blocks them outright). (https://dmarc.org/overview/)

For each item, tell me exactly which file to create or which code to change, and where it lives in a project using the stack above. If my framework has a native API for the task (e.g. Next.js metadata exports, `app/sitemap.ts`, Astro layouts, Nuxt `useHead`), prefer that over raw HTML or server config.

Using an autonomous agent?

Point the agent at this SKILL.md URL and ask it to follow the skill. The framing stops agents defaulting to an open-ended page review.

Share your score

Your score card renders automatically when you share the link.

Or embed a badge

Two badge options. Pick whichever fits your story.

Current score

Shows the latest score and updates within a few minutes of any recrawl. Best for ongoing display: if you fix something and recrawl, the badge reflects the new score automatically.

Launch score

Pinned to your launch-day snapshot and never changes. Marked with a small gold corner ribbon. Best for press kits, launch retrospectives, or anywhere you want a permanent record of how you shipped.

Using a Content-Security-Policy? Both badges are <img> tags from our domain, so your CSP needs to allow them. Add stackscope.dev to your img-src directive (example: img-src 'self' stackscope.dev;). Without it, browsers silently block the badge and visitors see a broken image.
