What
A background agent is a helper Claude starts to keep working on its own. A new line can be added to Claude's instructions: work that must go on after Claude's reply can instead run in a background agent, which runs its commands in the foreground. The line is added only when a feature check passes.
Why
It changes what Claude is told about using background agents, so Claude may hand ongoing work to one more often.
