CSS Dead Code Auditor

CSS only grows. Every sprint adds new rules; almost none get removed. A feature gets deleted — the styles stay. A component gets renamed — the old class selectors stay. After a year, 30-40% of your stylesheet is dead weight: downloaded by every user, parsed by every browser, doing nothing.

Point this skill at your project and get a complete inventory of dead selectors, their exact file locations, estimated byte savings, and safe-deletion commands.

Works with any CSS methodology. No config. No build step. Zero external APIs.
