Implementation Patterns

Across these use cases, several patterns emerge:

The Observe-Orient-Decide-Act Loop

Most agents follow this cycle:

1. Observe: Gather relevant information
2. Orient: Understand context and goals
3. Decide: Choose the best action
4. Act: Execute and observe results

Tool Composition

Agents combine multiple tools:

• Search + Read + Write
• Query + Analyze + Report
• Monitor + Alert + Respond

Human-in-the-Loop

For critical actions, agents seek approval:

• Recommend, don't act
• Draft, don't send
• Suggest, don't implement

Continuous Operation

Many agents run continuously:

• Monitor → Detect → Alert
• Watch → Update → Notify

Getting Started

Want to implement these use cases? Here's how:

1. Start with a specific pain point - Pick one use case that would provide clear value
2. Define success criteria - How will you know it's working?
3. Build minimally - Start with the simplest version that could work
4. Iterate based on feedback - Improve based on actual usage
5. Scale gradually - Expand scope once the core works

Conclusion

AI agents are not a future technology—they're working in production today across every industry and function. The 50 use cases here represent just a fraction of what's possible.

The key insight: agents excel at tasks that are:

• Repetitive but require judgment
• Information-intensive
• Multi-step but well-defined
• Time-sensitive but not mission-critical

If your work includes tasks matching these criteria, an AI agent can probably help.
