Defining Agent Goals and Objectives

Module 3: Designing and Architecting AI Agents

Defining Agent Goals and Objectives

A well-defined goal is the difference between a useful agent and a chaotic one.

Goal Decomposition

Break complex goals into manageable sub-goals:

Goal: "Write a research report on AI agents"

├── Sub-goal 1: Find relevant papers and articles

├── Sub-goal 2: Summarize key findings

├── Sub-goal 3: Identify themes and patterns

├── Sub-goal 4: Write structured report

└── Sub-goal 5: Add citations and references

Success Metrics and Evaluation

How do you know if your agent is doing well?

  • Task completion rate: % of tasks successfully completed
  • Accuracy: Correctness of outputs
  • Latency: Time to complete tasks
  • Cost: API tokens consumed per task
  • User satisfaction: Ratings, feedback

Constraints and Guardrails

What the agent should NOT do is as important as what it should:

  • Content guardrails: No harmful, biased, or inappropriate content
  • Action guardrails: Don't delete files, don't send emails without confirmation
  • Scope guardrails: Stay within the defined domain
  • Cost guardrails: Maximum tokens/API calls per request

Handling Ambiguity

Real-world requests are often ambiguous:

  • Ask clarifying questions when intent is unclear
  • Make reasonable assumptions and state them
  • Provide multiple options when appropriate
  • Know when to escalate to a human

Key Takeaways

  • Decompose complex goals into clear sub-goals
  • Define measurable success metrics before building
  • Guardrails prevent harmful or unintended behavior
  • Design for ambiguity — real users aren't precise
