Common questions
Does this work on the free Claude plan?
Yes. Skills work on every Claude plan — free, Pro, Max. You do need to enable Code execution and file creation in Claude's settings; the install guide walks through it.
Is this a prompt, or something different?
Different. A prompt is a sentence you have to remember and paste every time. A skill is a small instruction file Claude consults automatically when your request matches. Install once, forget about it.
Can I customize it for my class / business / voice?
Not in this tier. Ready-made skills are static. The customizable tier (coming soon) lets you set your name, voice, and defaults; or commission a custom-built skill if you want something specific.
What if it doesn't work?
