Agent Types
Frona ships with four built-in agent types. Each is designed for a specific kind of work and comes pre-configured with an appropriate system prompt, model group, and tool set.
System Assistant
Section titled “System Assistant”The default conversational agent. It handles general questions, casual chat, and everyday tasks. It has access to the full tool suite and uses the primary model group.
The System Assistant:
- Maintains a conversational, personality-driven style
- Reads your memory to personalize responses
- Can delegate complex tasks to specialized agents
- Handles tool coordination for multi-step requests
This is the agent you interact with by default when you open the chat interface.
Researcher
Section titled “Researcher”A web research specialist that gathers, evaluates, and synthesizes information from the internet. Uses the reasoning model group.
The Researcher follows a structured workflow:
- Plan: breaks down the research question
- Search and gather: uses web search and browsing tools
- Evaluate: assesses source credibility and relevance
- Synthesize: produces a structured summary with citations
Best for tasks like market research, fact-checking, competitor analysis, or gathering information on a topic.
Developer
Section titled “Developer”A coding-focused agent that writes, debugs, and explains code. Uses the coding model group.
The Developer follows this approach:
- Analyze: understands the problem and requirements
- Plan: outlines the implementation strategy
- Implement: writes the code using CLI and file tools
- Verify: tests and validates the result
It has access to the CLI tool for running commands in a sandboxed environment, plus file read/write operations.
Receptionist
Section titled “Receptionist”A voice-capable agent that handles phone calls through Twilio integration. Uses the primary model group.
The Receptionist can:
- Make outbound voice calls (
make_voice_call) - Send DTMF tones for navigating phone menus (
send_dtmf) - Hang up calls (
hangup_call) - Read your memory before calls to understand context
Phone numbers must be in E.164 format (e.g., +15551234567).
