Why isn't my skill triggering?
A skill called slow-code-finder is installed in your personal skills directory. It appears in Claude's available skills list — but it never activates when you ask Claude to find performance problems. Phrases like "why is this slow?" or "make this faster" all go unmatched.
The culprit is the description: "Optimization heuristics for Big-O regressions." Claude uses semantic matching between your request and the description; if the vocabulary doesn't overlap, the skill never fires.
