What is web-superpowers?

A website-quality add-on that checks accessibility, search-engine information, social-sharing metadata, and loading-performance measurements. WCAG is a set of guidelines for making websites usable by people with disabilities, while OpenGraph and JSON-LD are formats that describe pages to social networks and search engines.

Use it to audit and fix WCAG accessibility problems, add SEO and social-sharing metadata, and measure Core Web Vitals, which are standard browser performance measurements.

It helps find website issues that can make pages harder to use, less visible in search, or slower to load.

Security

Grade A, and why

web-superpowers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
