Enabled execution is separate from a saved configuration.
Agents overview
Scope
The six categories are Extraction, Knowledge Graph, Semantic Search, Source Finder, Paragraph Vector Analyzer, and Accuracy Review. A tool can read a collection you can access. Execution still needs agent:run. This guide does not add tools that are not on the rail.
Saved agents
Saved agents are reusable extraction configurations. Availability Available means the configuration can be opened. It is not a grounded answer.
A starter tool
Choose a collection, inspect the passages, and leave. If you need the configuration again, save an extraction agent from the catalog instead of expecting the tool session to remain.
