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 23 Jan 2027 as of our check on 13 Nov 2026.

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

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE2 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

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 elena.brainfoundry.ai controls every word below.

ask

Answer a question from this brain's public-scoped memory, citing the documents used.

agenttru.st compared this card's skill list with every other listing's: 4 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 5. That says the cards' text is the same, not who runs them.

Technical agent card

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

Protocol: a2a
Version: 0.13.0
Auth schemes: brainfoundry-ed25519
Extensions: urn:brainfoundry:ask-assertion:v1 — required of clients
Each request carries an ED25519 federation assertion (iss, aud, sub='ask', iat, exp, jti, qh=sha256 of the question).

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
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.
