Agents

sparqld gives agents a read-only query surface over the files in your knowledge base. Give the agent the endpoint URL and a way to send SPARQL HTTP requests, such as the sq client. To give agents the local query workflow, install the skill from the GitHub repository:

npx skills add https://github.com/iolanta-tech/sparqld --skill sparqld --agent '*'

With the example dataset running, ask your agent:

Youuser.prompt

In $sparqld, find information about known planets in Alpha Centauri system, and show me the query you used to obtain that.

Codexcodex.response

Using the sparqld skill, I inspected the knowledge base vocabulary and followed the recorded star and system links. It records two planets in the Alpha Centauri system: Proxima Centauri b and Proxima Centauri d.

The query and its result are shown below.

Query used alpha-centauri-planets.rq

PREFIX dbo: <http://dbpedia.org/ontology/>
