What

Three small changes:

  • Tool-name matching now ranks results: an exact name match scores highest, a partial match comes next, and a match on intent comes last.
  • A list of account attributes has a new entry, ccrDerivedSurface.
  • A script built into Claude Code now runs in JavaScript's strict mode, which reports some coding mistakes as errors.
Why

These are minor changes. The new account attribute may relate to a new cloud surface.
