Agentic Workflow

Agent workflow Agentic pattern AI workflow automation

Definition

An agentic workflow is a structured pattern where AI agents autonomously execute multi-step tasks through iterative cycles of planning, action, observation, and refinement. Unlike simple prompt-response interactions, agentic workflows enable complex problem-solving with tool use and self-correction.

Agentic workflows are the blueprints for how AI systems accomplish real-world tasks independently.

Key Concepts

  • Orchestration: Coordinating multiple steps and tools
  • Iteration: Loops that refine results until satisfactory
  • Checkpoints: Human approval gates for critical decisions
  • Fallbacks: Error handling and recovery strategies

Interactive Exercise

Design a Workflow

Design an agentic workflow for a "Blog Post Writer" agent. What steps would it take? Where would it iterate? Where would it need human input?

Pro Tips
  • Start with the simplest workflow that works, then add complexity
  • Always include timeout limits on iterative loops
  • Log every step for debugging and audit trails
  • Design graceful degradation when tools fail
