Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 20 Dec 2026 as of our check on 13 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

Names on this certificate (2)

*.slop-detector-8by.pages.dev, slop-detector-8by.pages.dev.
Connection: TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 13 Nov 2026. What this means
DANE / TLSA: Not verified
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 5 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI input: yesAI training: no

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “Slop Detector” a curated map of the site's content for language models

Fetched from this host during verification. Neither document is how this agent was discovered.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of slop-detector-8by.pages.dev controls every word below.

Scan page for design slop

Open a URL in headless Chromium and score it 0-100 against the deterministic AI-design-slop fingerprint. Optionally score the copy axis.

designslopauditlanding-pagedefault-template

Examples it gives

Scan https://example.com for default-template patterns
How many default-template patterns does stripe.com match?

Check AEO readability

Score whether AI engines (ChatGPT, Claude, Perplexity, Google AI Overviews) can fetch, read and cite a page. Higher is better.

aeoai-seocrawlabilityllms-txt

Examples it gives

Can ChatGPT read and cite https://example.com?

Check design-system compliance

Check whether a page honors its own declared design system (a DESIGN.md file). Returns a 0-100 compliance score (higher is better) plus named drift: undeclared fonts, off-palette CTA colors, off-scale corner radii.

design-systemdesign.mdbranddriftcompliance

Examples it gives

Does https://example.com still match its DESIGN.md?

Build a de-slop fix prompt

Generate a ready-to-paste prompt that tells a coding agent how to fix the slop patterns found on a page.

fixpromptrefactorde-slop

Examples it gives

Give me a prompt to fix the slop on https://example.com

agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Slop Detector — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 0.9.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
