Claude reads every label before starting a task, picks the right toolbox off the shelf, then opens it. if your label is vague, claude walks right past it every time and won't activate when you need it the label needs two things: 1. what the skill does 2. and the kind of thing someone would say when they need it the problem is most people only do number 1 and write something vague like: - "helps with projects" - "creates documentation" - "manages workflows" claude reads those and has no idea when to use them. so the skill just sits there. you built the toolbox but claude never picks it up the fix is dead simple:...
