Unable to send requests to Model providers when embedding Skills in Cursor prompts

As the title describes, when attaching these Skills into a prompt within a Cursor chat e.g 'hello, please execute /skill-name' once the request is sent, an error occurs stating 'an unexpected error occurs on our servers'. No further requests will process to any model provider and all context is lost.

The workaround is to is to explicitly tell the agent to lookup the Skill and execute it, without embedding it in the chat.

Quite a strange bug, unsure what the cause is. I have raised this with Cursor also. I have been using Skills for over a year, and have only experienced this issue with these Skills.

The only suspicion I have is that it is potentially being caused due to the length of these Skills in comparison to others.
