What
Claude has tools that list the claude.ai plugins and skills you have and suggest new ones. Plugins and skills are add-ons that extend what Claude can do. These tools changed in three ways:
- They now carry guidance on when to use them, for example for when you ask which claude.ai skills you already have enabled.
- They now carry an ID that identifies each tool in a registry.
- A list can now come back with a note saying it stopped at a page limit.
Sometimes the search or list service refuses a request and the tool falls back to an empty result. Before, that was always recorded as your account not being entitled to the feature. A refusal that comes from a sandbox, meaning a restricted environment that blocks certain access, is now recorded as a sandbox refusal.
Why
The guidance helps Claude choose the right tool when you ask about your plugins and skills. Keeping sandbox refusals separate from entitlement failures means an empty list is no longer always put down to your account.
