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 Google Trust Services domain-validated

Valid until 15 Jan 2027 as of our check on 31 Oct 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-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

Names on this certificate (2)

heldenlounge.de, *.heldenlounge.de.

Connection

DANE / TLSA

Not verified (TLSA query returned RCodeNameError)

Discovery

Well-known document

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 1 resource. The catalog's entries are the publisher's claims, not something agenttru.st verified.

AI-facing documents

Publishes /llms.txt — “Heldenlounge” 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 staging.heldenlounge.de controls every word below.

agenttru.st compared this card's skill list with every other listing's: 15 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 16. That says the cards' text is the same, not who runs them.

What kind of listing

• Test or staging name: Its hostname carries the label “staging”, a name commonly given to test and staging sites.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

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.
