# Agents
> AI workers that do the parts you can't draw as steps
Describe the job. Give it tools. It figures out the rest.
## What is an agent?
An agent is someone you brief rather than something you configure. You write down the job in plain language, give it access to the apps it needs, and it handles the work as it arrives.
Each time it runs, it reads the situation, decides which tools to use, and keeps going until the job is done. Two similar cases can be handled differently, the same way a colleague would treat them differently.
## Flow or agent?
| | Flow | Agent |
| -------------------- | ---------------------- | ------------------------- |
| **The logic is** | Written down once | Worked out each run |
| **Same input twice** | Same steps every time | May handle it differently |
| **Best when** | You know the procedure | The work varies |
## What it can do
Any action from 760+ pieces becomes a tool it can call.
Answers grounded in your documents and tables.
Run one as a step and get structured data back.
Say what you need and the agent gets written for you.
