Oikos bronze

valaidator.com

“Oikos turns an organization's contracts and other documents into a cited knowledge base, organised in spaces. Ask questions, search, read a document's extracted fields or get summaries; every answer cites its sources (document, page, quote, link). Read-only: a request to change something comes back as input-required with a link where a person makes the change in Oikos.

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 14 Jan 2027 as of our check on 6 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 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 valaidator.com controls every word below.

Ask

Answers a question from a space's documents (contracts, invoices, policies, correspondence) with citations: a Markdown text part with the sources linked, and a data part with each citation's document, page, verbatim quote and link into Oikos. Follow-ups in the same contextId continue the conversation. Choose the space with the message's metadata {"space": "<space id or name>"} (the extended card lists them); a follow-up in the same contextId stays in its space, and a credential that reaches one space uses it.

documentscontractsquestion answeringcitations

Examples it gives

Check our contracts with Acme for change-of-control clauses.
Which agreements renew automatically in the next 90 days, and what is their notice period?

Search

Hybrid search (meaning, keywords and exact reference numbers) over a space's pages, extracted facts and wiki: ranked hits with document, page, snippet and link. Send the query as text, or a data part {"query": "...", "limit": 10} for the hits without a written answer. Choose the space with the message's metadata {"space": "<space id or name>"} (the extended card lists them); a follow-up in the same contextId stays in its space, and a credential that reaches one space uses it.

searchdocuments

Examples it gives

termination for convenience
{"query": "MSA-2023-014", "limit": 5}

Get a document

One document's type, pages and extracted fields, each field with its page and verbatim quote. Name the document in text, or send a data part {"document_id": "<id>"}. Choose the space with the message's metadata {"space": "<space id or name>"} (the extended card lists them); a follow-up in the same contextId stays in its space, and a credential that reaches one space uses it.

documentsextraction

Examples it gives

Show the extracted fields of the Globex master services agreement.

Summarize

Summarizes a document or a set of documents (parties, key terms, amounts, dates, obligations), every statement cited. Choose the space with the message's metadata {"space": "<space id or name>"} (the extended card lists them); a follow-up in the same contextId stays in its space, and a credential that reaches one space uses it.

summarydocuments

Examples it gives

Summarize the amendments to our lease with Initech.
