State the intended value and scope, then inspect the selected file and resulting diff. Review the scope of permission and hook changes before relying on them.

The official Commands table includes this skill in the September 22, 2026 audit. It does not specify an introduction version, so this page does not infer one.

Choosing related commands

  • /config [key=value ...]: set supported preferences directly or open Settings
  • /permissions: manage allow, ask, and deny rules
  • /hooks: inspect configured hooks

Effects and persistence

Edits the matching settings.json. Verify the user or project scope and the resulting diff.
