LRRK Library Agent bronze

staging.lrrk.ai

“Search the LRRK public research library and retrieve paper records and download links. Synchronous structured-data requests use the existing library:read agent credential. This agent provides catalog information; it does not perform assurance assessments or generate reports. Also produces merchant-signed AP2 cart artifacts. Payment uses the separate native x402 endpoint; AP2 PaymentMandate execution is not supported. Activate both required AP2 identifiers for all requests to this card's interface.

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 13 Jan 2027 as of our check on 11 Nov 2026.

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.

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 2 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.

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.

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.lrrk.ai controls every word below.

Search library papers

Send one JSON data part: {"skillId":"list_library_papers","query":"optional title or keyword filter","kind":"optional exact kind filter"}. Returns matching paper summaries and download links.

researchlibrarysearch

Examples it gives

{"skillId":"list_library_papers","query":"robotics"}

Read a paper record

Send one JSON data part: {"skillId":"get_library_paper","slug":"a slug from list_library_papers"}. Returns the full catalog record, abstract and download link.

researchlibrarypaper

Examples it gives

{"skillId":"get_library_paper","slug":"REPLACE_WITH_LISTED_SLUG"}

Create a signed library cart

Send one JSON data part: {"skillId":"create_library_cart"}. Returns a completed Task with a merchant-signed AP2 CartMandate artifact for the current fixed-price library offer. No charge is made. Payment remains a separate native x402 request after user confirmation. See https://lrrk.ai/ap2/cart-v0.1.0.md.

Examples it gives

{"skillId":"create_library_cart"}

agenttru.st compared this card's skill list with every other listing's: 2 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 3. 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.
