How is a tool different from a skill?

A skill teaches an agent a focused way to work. A tool gives an agent an extra connection or capability.

Are public tools free?

Every public tool is free at launch. A tool may still require an Alysium Pro plan, which is shown separately on its listing.

Will choosing a tool connect it automatically?

No. You select an agent, review any setup, and confirm the tool inside the builder.

How tools work

1
Find the missing connection
Start with the extra thing your agent needs to reach, read, or do.
2
Check requirements
Open the tool to see its type, purpose, creator, price, and whether it needs Alysium Pro.
3
Connect it deliberately
Choose the agent that needs the tool, review the setup, and confirm in the builder.

Choose with confidence

Three quick checks can tell you more than a long description.

The right capability

Make sure the tool solves a real gap in your agent instead of adding complexity you do not need.

Visible requirements

Check whether the tool needs a Pro plan or extra setup before you continue.

Safe information

Use non-confidential test material first and understand what information the tool will receive.

Have an idea for a useful tool?

Create a tool people can add to their Alysium agents. Start by describing what it should help with, and Alysium will guide you through the setup. You do not need to write code to begin.
