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 feedback.dev.ylang.education controls every word below.

Evaluate step

Evaluate a single step (≤5 word concise FR text + TTS S3 key).

feedbackstep

Examples it gives

{"action":"evaluate_step","activityId":"…","stepIndex":0,"answers":[{"id":"q1","values":[{"type":"text","value":"a"}]}],"targetLanguage":"en"}

Evaluate activity

Evaluate a flat activity (pedagogical FR feedback + TTS).

feedbackactivity

Examples it gives

{"action":"evaluate_activity","activityId":"…","answers":[…]}

Global feedback

Global pedagogical recap after a steps sequence (text + TTS).

feedbackglobal

Examples it gives

{"action":"global_feedback","activityId":"…","stepResults":[…]}

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 kind of listing

Test or staging name: Its hostname carries the label “dev”, a name commonly given to test and staging sites.
Private endpoint: Its card names an endpoint on feedback.common.svc.cluster.local, which is not reachable from the public internet.

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.

Technical agent card

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

Protocol: a2a
Version: 1.0.0
Extensions: https://ylang.education/extensions/ag-ui/v1
AG-UI protocol

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.
