@readystack/age-gate-lint

Age Gate Lint — UK Online Safety Act

8 rules for Ofcom's highly effective age assurance duty, in force since 25 July 2025, where the penalty ceiling is £18m (£18 million) or 10% of qualifying worldwide revenue. One sample vape storefront page returned 13 findings, 10 of them high severity.

Install

npx @readystack/age-gate-lint file

Node 18+. The same 8 rules as the VS Code extension, from a terminal or CI.

Free

• Reads the HTML file you have open and names every weak point in its age gate — all 8 rules, line numbers, Ofcom clause, severity — no key asked.
• --rules lists every rule

With a licence ($29 once)

• Runs the same 8 rules across every HTML file in the workspace in one pass and writes a dated evidence report you keep and can hand to a client or to Ofcom.

@readystack/age-gate-lint --dir ./templates --report html --out report.html

A freelance web developer bills about $60/hour; a manual pass over one storefront's gate plus the written note is roughly half a day, near $240.
