# Security Headers Lint - CSP and Dead Headers

Reads security headers and CSP line by line in your config file and names the lines that silently do nothing: retired headers, keywords missing their quotes, directives the browser throws away.

Runs entirely in your browser. Nothing is uploaded, nothing is stored.
