When to Use an Agent complex workflows multiple decision steps tool orchestration When NOT to Use an Agent simple automation no reasoning required direct workflows Why This Matters Using an agent when not needed: increases complexity reduces efficiency
Why Tools Matter Well-designed tools: improve accuracy reduce cost enable scalability Poor Tool Design too much data unclear structure confusing outputs Best Practices manage tool outputs keep structure consistent handle errors properly Tool Output Impact large outputs increase token usage affects performance and cost Designing Effective Tools for AI Agents Why Tools Matter Well-designed tools: improve accuracy reduce cost enable scalability Poor Tool Design too much data unclear structure confusing outputs Best Practices manage tool outputs keep structure consistent handle errors properly Tool Output Impact large outputs increase token usage affects performance and cost
Spoofing & Impersonation Risks What Is Spoofing? When a user pretends to be someone else and the agent accepts it without verification.
