benchmark

benchmark is a skill for Claude Code, Codex from Ertinox7711/SGRR-AGI-V2. It costs 94 tokens per session (8,768 once invoked), scanned A, a copy of document-generate, MIT.

A web performance checker that records page-load baselines, Core Web Vitals, and resource sizes, then compares them across changes. Core Web Vitals are browser measures of loading speed, responsiveness, and visual stability.

In plain words
What is it for?
Use it to measure page speed, bundle size, load time, and performance changes in pull requests.
Why use it?
It helps detect when a change makes a website slower or increases its downloaded files. Comparing results over time shows performance regressions before they become harder to fix.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

benchmark scanned grade A with 1 finding 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 3d 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.
