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.
Learn more

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
LOWAdd MTA-STS
No MTA-STS DNS record published.
WhyPrevents mail to your domain being downgraded to plaintext mid-flight by a network attacker. Most launches don't have this, so deploying it puts you a tier above generic email-security checks.
WherePublish a TXT record at _mta-sts.{your-domain} plus a policy file at https://mta-sts.{your-domain}/.well-known/mta-sts.txt.
Learn more
LOWAdd a TLS-RPT record
No TLS-RPT record at _smtp._tls.{domain}.
WhyReceivers can tell you when STARTTLS handshakes to your mail server fail. Without it, silent TLS failures are invisible.
WherePublish one TXT record at _smtp._tls.{your-domain} like v=TLSRPTv1; rua=mailto:[email protected].

Page basics & SEO

LOWTrim your <title> tag to under 60 characters
Currently 86 characters: "Staff scheduling for bars, restaurants & hotels — free up to 20 staff | SuperShift"
WhyGoogle truncates titles around 60 characters in search results, so anything past that gets cut off mid-sentence and costs click-through rate.
WhereAim for 50-60 characters that include your main keyword and brand.
Learn more
LOWTrim your meta description to under 160 characters
Currently 177 characters: "SuperShift is the drag-and-drop scheduling tool hospitality teams actually use. Built for Belgian flexi-jobs and student-uren. Free up to 20 staff, no demo call, no credit card."
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.

Performance

MEDIUMSet width and height on your images
2 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
2 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
2 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

LOWDeclare a Content-Signal in robots.txt
WhyStates how you'd like AI systems to use your content (training, search, agent input). Without it, AI crawlers fall back to whatever default policy each vendor applies.
WhereAdd a Content-Signal: line to your robots.txt.
Learn more
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://supershift.work/home. StackScope (https://stackscope.dev) analysed it on 4 June 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:
amazon-ses, google-site-verification, hsts, namecheap-dns, nextjs, react, resend, tailwindcss, vercel

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://supershift.work/home. StackScope (https://stackscope.dev) analysed it on 4 June 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.

Tech stack StackScope detected on the site (use this when suggesting where each fix lives in the codebase):
amazon-ses, google-site-verification, hsts, namecheap-dns, nextjs, react, resend, tailwindcss, vercel

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/)
- [MEDIUM] Set width and height on your images. 2 images render without explicit width/height. Why: Without intrinsic dimensions the browser can't reserve space before the image loads, so content jumps as it arrives (cumulative layout shift). Where: Add `width` and `height` attributes (or an `aspect-ratio` CSS rule). Framework image components set these for you. (https://web.dev/articles/cls)
- [LOW] Trim your <title> tag to under 60 characters. Currently 86 characters: "Staff scheduling for bars, restaurants &amp; hotels — free up to 20 staff | SuperShift" Why: Google truncates titles around 60 characters in search results, so anything past that gets cut off mid-sentence and costs click-through rate.

Put the most click-worthy phrase first. (https://developers.google.com/search/docs/appearance/snippet)
- [LOW] Add /.well-known/security.txt. Why: Lets security researchers report vulnerabilities responsibly through a published contact channel. Where: Create `/.well-known/security.txt` with a `Contact:` email and `Expires:` date. (https://securitytxt.org/)
- [LOW] Declare a Content-Signal in robots.txt. Why: States how you'd like AI systems to use your content (training, search, agent input). Without it, AI crawlers fall back to whatever default policy each vendor applies. Where: Add a `Content-Signal:` line to your `robots.txt`. (https://contentsignals.org/)
- [LOW] Add Link response headers. Why: Lets agents discover your sitemap, privacy policy, and docs without parsing HTML, which most lightweight agents skip. Where: Set `Link:` response headers in your server config or framework middleware. (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Link)
- [LOW] Add MTA-STS. No MTA-STS DNS record published. Why: Prevents mail to your domain being downgraded to plaintext mid-flight by a network attacker. Most launches don't have this, so deploying it puts you a tier above generic email-security checks. Where: Publish a TXT record at `_mta-sts.{your-domain}` plus a policy file at `https://mta-sts.{your-domain}/.well-known/mta-sts.txt`. (https://datatracker.ietf.org/doc/html/rfc8461)
- [LOW] Add a TLS-RPT record. No TLS-RPT record at `_smtp._tls.{domain}`. Why: Receivers can tell you when STARTTLS handshakes to your mail server fail. Without it, silent TLS failures are invisible. Where: Publish one TXT record at `_smtp._tls.{your-domain}` like `v=TLSRPTv1; rua=mailto:tls-reports@yourdomain.com`. (https://datatracker.ietf.org/doc/html/rfc8460)
- [LOW] Serve right-sized images. 2 images are downloaded at more than twice the displayed size. Why: Shipping a 2000px image into a 400px slot wastes bandwidth and slows loading, especially on mobile. Where: Resize to the displayed dimensions, or use `srcset`/`sizes` (or a framework image component) to serve per-viewport variants. (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#srcset)
- [LOW] Add alt text to your images. 2 images have no alt attribute. Why: Screen-reader users get no description, and search engines lose a signal about the image content. Where: Add a concise `alt="..."` to each image (an empty `alt=""` is correct only for purely decorative images). (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#alt)

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.

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.
