Tool Composition
Agents combine multiple tools:

- 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:
- Start with a specific pain point - Pick one use case that would provide clear value
- Define success criteria - How will you know it's working?
- Build minimally - Start with the simplest version that could work
- Iterate based on feedback - Improve based on actual usage
- 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.
