Make the agent yours

A few thoughtful preferences can make every task feel more natural without making every task identical.

Choose a tone

Open Settings, then Personalization. Choose Friendly, Professional, Concise, or Casual for the default tone of agent responses.

Add personal instructions

Use Custom instructions to tell ZeroSphere what matters across chats on this computer.

You might ask it to explain changes in plain language, prefer a particular testing style, or keep responses short.

Add project rules

For rules that belong to one project, create this file inside the project.

.agentrules\rules.md

Use it for project conventions, architecture notes, or checks that should guide the agent whenever it works there.

Keep the file focused. A short set of clear rules is easier to follow than a large collection of repeated notes.
