You think in terms of roles, responsibilities, and delegation. You design clear agent personas with specific expertise, create well-defined tasks with expected outputs, and orchestrate crews for optimal collaboration. You know when to use sequential vs hierarchical processes. ## Capabilities - Agent definitions (role, goal, backstory) - Task design and dependencies - Crew orchestration - Process types (sequential, hierarchical) - Memory configuration - Tool integration - Flows for complex workflows ## Requirements - Python 3.10+ - crewai package - LLM API access ## Patterns ### Basic Crew with YAML Config Define agents and tasks in YAML (recommended) **When to use**: Any CrewAI project ```python # config/agents.yaml researcher: role: "Senior Research Analyst" goal: "Find comprehensive, accurate information on {topic}" backstory: | You are an expert researcher with years of experience in gathering and analyzing information. You're known for your thorough and accurate research. tools: - SerperDevTool - WebsiteSearchTool verbose: true writer: role: "Content Writer" goal: "Create engaging, well-structured content" backstory: | You are a skilled writer who transforms research into compelling narratives. You focus on clarity and engagement. verbose: true # config/tasks.yaml research_task: description: | Research the topic: {topic} Focus on: 1. Key facts and statistics 2. Recent developments 3. Expert opinions 4. Contrarian viewpoints Be thorough and cite sources. agent: researcher expected_output: | A comprehensive research report with: - Executive summary - Key findings (bulleted) - Sources cited writing_task: description: | Using the research provided, write an article about {topic}. Requirements: - 800-1000 words - Engaging introduction - Clear structure with headers - Actionable conclusion agent: writer expected_output: "A polished article ready for publication" context: - research_task # Uses output from research # crew.py from crewai import Agent, Task, Crew, Process from crewai.project import CrewBase, agent, task, crew @CrewBase class ContentCrew: agents_config = 'config/agents.yaml' tasks_config = 'config/tasks.yaml' @agent def researcher(self) -> Agent: return Agent(config=self.agents_config['researcher']) @agent def writer(self) -> Agent: return Agent(config=self.agents_config['writer']) @task def research_task(self) -> Task: return Task(config=self.tasks_config['research_task']) @task def writing_task(self) -> Task: return Task(config ``` ### Hierarchical Process Manager agent delegates to workers **When to use**: Complex tasks needing coordination ```python from crewai import Crew, Process # Define specialized agents researcher = Agent( role="Research Specialist", goal="Find accurate information", backstory="Expert researcher..." ) analyst = Agent( role="Data Analyst", goal="Analyze and interpret data", backstory="Expert analyst..." ) writer = Agent( role="Content Writer", goal="Create engaging content", backstory="Expert writer..." ) # Hierarchical crew - manager coordinates crew = Crew( agents=[researcher, analyst, writer], tasks=[research_task, analysis_task, writing_task], process=Process.hierarchical, manager_llm=ChatOpenAI(model="gpt-4o"), # Manager model verbose=True ) # Manager decides: # - Which agent handles which task # - When to delegate # - How to combine results result = crew.kickoff() ``` ### Planning Feature Generate execution plan before running **When to use**: Complex workflows needing structure ```python from crewai import Crew, Process # Enable planning crew = Crew( agents=[researcher, writer, reviewer], tasks=[research, write, review], process=Process.sequential, planning=True, # Enable planning planning_llm=ChatOpenAI(model="gpt-4o") # Planner model ) # With planning enabled: # 1. CrewAI generates step-by-step plan # 2. Plan is injected into each task # 3. Agents see overall structure # 4. More consistent results result = crew.kickoff() # Access the plan print(crew.plan) ``` ## Anti-Patterns ### ❌ Vague Agent Roles **Why bad**: Agent doesn't know its specialty. Overlapping responsibilities. Poor task delegation. **Instead**: Be specific: - "Senior React Developer" not "Developer" - "Financial Analyst specializing in crypto" not "Analyst" Include specific skills in backstory. ### ❌ Missing Expected Outputs **Why bad**: Agent doesn't know done criteria. Inconsistent outputs. Hard to chain tasks. **Instead**: Always specify expected_output: expected_output: | A JSON object with: - summary: string (100 words max) - key_points: list of strings - confidence: float 0-1 ### ❌ Too Many Agents **Why bad**: Coordination overhead. Inconsistent communication. Slower execution. **Instead**: 3-5 agents with clear roles. One agent can handle multiple related tasks. Use tools instead of agents for simple actions. ## Limitations - Python-only - Best for structured workflows - Can be verbose for simple cases - Flows are newer feature ## Related Skills Works well with: `langgraph`, `autonomous-agents`, `langfuse`, `structured-output` ## When to Use This skill is applicable to execute the workflow or actions described in the overview. --- Source attribution: pinkpixel-dev Original project: https://github.com/pinkpixel-dev/skills-collection-1/blob/dc709653773653302e333a45d3b6f3b70fdff8f8/SKILLS/crewai/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
