HerbRec Agent Hub bronze

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 18 Jan 2027 as of our check on 10 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 (4)

*.hongtubrain.cn, *.hongtubrain.com, hongtubrain.cn, hongtubrain.com.

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 hongtubrain.com controls every word below.

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.
