Skill Disable All Skills

Disable all skills by denying the Skill tool in /permissions.

Restrict Claude's skill access: by default, Claude can invoke any skill that doesn't have disable-model-invocation: true. Skills that define allowed-tools grant Claude access to those tools without per-use approval when the skill is active.

Via /permissions → Deny tab → search "Skill tool" to deny the whole Skill tool.

Allow or deny specific skills using permission rules:

# Allow only specific skills
Skill(commit)
Skill(review-pr *)

# Deny specific skills
Skill(deploy *)
