01

Connect a tool

Use Tools & MCP to add the service you need. Confirm its connection and review the tools it exposes.

02

Add a skill

Open Skills to create or import a reusable workflow. Read its instructions before installing it. Skills are instructions, not a new permission grant.

03

Try one bounded task

Ask your agent for a small result, review the tool call and approval, and check the returned output before relying on it in a routine.

Try it with a small task

Write a short summarization skill and invoke it on non-sensitive text. Confirm the result follows its requested structure.

If it does not work

  • Skill not offered: try a fresh chat or explicit slash invocation.
  • MCP tool fails: check service authentication, transport and the actual error result.

Good to know

  • Web Search, Browser Use and Computer Use have separate configuration and access requirements.
  • A connected service can expose several tools; its tool count is not a count of agents.
