What are features?

Features are optional platform capabilities attached to your agent. When a feature is enabled, the runtime adds the right tools and prompt instructions so the model knows when and how to use them. You toggle features per agent using the CLI (lua features) or via the platform APIs. For full command options and interactive flows, see the Features command reference.

Current features

There are three built-in features: Knowledge Search (rag), Web Search (webSearch), and Inquiry Forms (inquiry).

​
Knowledge Search (rag)

RAG-based search over your agent’s resources (documents you upload as the knowledge base). What it does: Lets the agent retrieve relevant passages from your uploaded materials and answer with citations. How you add knowledge: Use lua resources from a skill project, or upload documents in the Admin Dashboard (recommended for many teams). Almost any common document type can be processed and used for retrieval. Best for: FAQs, policies, product docs, internal knowledge that should stay in your data—not the open web. See also: Resources.

​
Web Search (webSearch)

Real-time answers grounded in web search results. What it does: The agent can run a web search for a natural-language query and get a synthesized answer plus source links. It is not a web scraper: it does not open arbitrary URLs or extract full page HTML. Best for: Current events, public facts, or anything not in your uploaded resources. For details and limitations, see the Features command reference (Web Search section).

​
Inquiry Forms (inquiry)

Structured data collection through conversational forms you define. What it does: The agent can present forms (questions/fields), collect responses, and store submissions. Submissions appear in the Admin Dashboard so your team can review them—similar to how legacy “support tickets” worked, but inquiry forms are general-purpose (leads, intake, feedback, or support-style flows). Best for: Lead capture, onboarding questionnaires, support intake, or any workflow where you need structured answers from users.

​
Enabling and disabling features

From your skill project directory (with lua.skill.yaml configured): 
lua features list
lua features enable --feature-name rag
lua features disable --feature-name webSearch
lua features view --feature-name inquiry
See Features command for interactive mode, context editing, and troubleshooting.
