What

Skills are packaged instructions Claude can load and use. A skill can now be marked withheld, which Claude Code treats as switched off for the current session.

  • A listed skill with withheld set to true and no command is treated as switched off. The message Claude gets reads "Skill ... is switched off for this session."
  • Placeholders for withheld skills are taken out of the normal skill list and kept separately.
  • When Claude tries to use a synced skill (one fetched from elsewhere) and the download result is flagged withheld, the reply is built from the skill's name and ends with "Proceed without it." Other failed downloads still get the old "could not be downloaded" message.

Before this release, a failed skill download always produced the "could not be downloaded" message.

Why

A skill that is deliberately turned off for a session no longer looks like a download failure. Claude is told plainly that the skill is unavailable and to carry on without it.
