Documentation

Overview

Package roles provides role support for omniagent.

Roles are high-level agent personas that combine skills, workflows, and system prompts into cohesive behaviors. They provide a way to configure agents for specific use cases like "Meeting PM" or "Investment Analyst".

Role Architecture

A role defines:

  • Required and optional skills it needs
  • System prompt modifications for the persona
  • Workflows for multi-step operations

Usage 

// Create a role with its configuration
pmRole := meetingpm.New(meetingpm.Config{
    DefaultConfluenceSpace: "TEAM",
})

// Create the skills the role needs
meetingSkill := meeting.NewSkill(...)
googleSkill := google.NewSkill(...)

// Register role with agent
agent, err := agent.New(config,
    agent.WithRole(pmRole, meetingSkill, googleSkill),
)
