Claude Code v2.1.281 ·

Auto-mode classifier option onlyBuiltInContext is read but nothing sets it

Auto mode's permission classifier has an unused onlyBuiltInContext option; nothing sets it, so behaviour is unchanged

What

In auto mode, a classifier (an automatic checker) decides whether an action Claude wants to take is allowed. It now reads an option called onlyBuiltInContext. When true, the classifier would skip the extra context it normally gathers about the tool being judged and use a reduced prompt. Nothing in Claude Code sets this option, so the classifier behaves exactly as before.

Why

There is no change you can see. A reduced-context mode for the classifier exists in the code but cannot be reached yet.
