Overview

This skill is a multi-agent orchestration framework that builds teams of autonomous AI agents for complex, role-based collaboration. It offers crews (autonomous teams) and flows (event-driven routers), built with a lean footprint and no LangChain dependency. The design emphasizes production readiness with memory, tracing, and built-in tools for research, scraping, and document handling.

How this skill works

Define Agents with roles, goals, backstories, LLMs, and tools, then assemble Tasks and a Crew or Flow to run them. Crews execute tasks sequentially or hierarchically (with a manager agent), while Flows handle event-driven routing and conditional logic. Memory (short-term, long-term, entity) and tool integrations (50+ built-ins) enable persistent context and external data access during runs.

When to use it

• Building teams of specialized agents that must collaborate autonomously
• Orchestrating sequential or hierarchical workflows with clear task delegation
• Production workflows that require memory, observability, and rate limits
• Event-driven processes needing conditional routing and stateful flows
• Projects where you want a lighter alternative to LangChain with built-in tools

Best practices

• Give each agent a clear, narrow role and goal to avoid overlap
• Use YAML for agent/task configs to simplify maintenance and reuse
• Enable memory for multi-step contexts and set sensible embedding providers
• Limit tools per agent (3–5 recommended) and set max_iter to prevent loops
• Apply rate limits (max_rpm) and enable tracing for production observability

Example use cases

• Research pipeline: researcher agent scrapes and summarizes sources, writer produces articles
• Data analysis workflow: analyst ingests files, calculator or code tools run computations, reporter compiles results
• Manager-worker setup: hierarchical process where manager delegates subtasks to specialists
• Event-driven monitoring: Flows listen to inputs, run analysis crews, and route outputs based on confidence
• Production automation: scheduled crews with persistent memory and token usage tracking
