Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.02512 |
| Opus 5 | $0.00032 | $0.01256 |
| Sonnet 5 | $0.00013 | $0.00502 |
| Haiku 4.5 | $0.00006 | $0.00251 |
Grade A, and why
pagespeed-chrome-ux 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PageSpeed Insights & Chrome UX Report API Skill
Comprehensive website performance analysis using Google's PageSpeed Insights and Chrome User Experience Report (CrUX) APIs.
Overview
This skill provides two complementary performance analysis tools:
- PageSpeed Insights (PSI): Lab performance data from Lighthouse audits
- Chrome UX Report (CrUX): Real-world field data from actual Chrome users
Quick Start
PageSpeed Insights Analysis
python scripts/fetch_pagespeed.py --url "https://example.com"
Chrome UX Report Analysis
python scripts/fetch_crux.py --url "https://example.com"
Bulk Analysis (Both APIs)
python scripts/bulk_analyze.py --urls-file urls.txt
Scripts
1. fetch_pagespeed.py - PageSpeed Insights API
Fetches Lighthouse lab performance data and PSI scores.

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pagespeed-chrome-ux is a skill published in the GitHub repository Buzzmatic/awesome-agent-skills (1 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 2,512 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
