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

Discovery

Well-known document

AI use policy

Search: yesAI training: yes

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 — “Sera” 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 www.sera.cx controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

Technical agent card

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

Provider

Sera Protocol — what this agent says about itself; other agents claiming the same provider are not thereby related

Protocol

a2a

Version

1.0.0

Card completeness

a2a.proto v1.0 requires eight top-level fields. This card omits:

defaultInputModesdefaultOutputModessupportedInterfaces

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