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 | $0.00037 | $0.00204 |
| Opus 5 | $0.00018 | $0.00102 |
| Sonnet 5 | $0.00007 | $0.00041 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
playwright 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 yesterday.
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 it actually says
Download the rendered HTML instead of PDF or screenshots. Use the Playwright CLI:
npx playwright open --save-har=/tmp/page.har --save-har-glob="**" <url> --headless
Or more directly, dump the fully rendered DOM:
node -e "const{chromium}=require('playwright');(async()=>{const b=await chromium.launch();const p=await b.newPage();await p.goto(process.argv[1],{waitUntil:'networkidle'});console.log(await p.content());await b.close()})();" <url> > /tmp/page.html
Then read /tmp/page.html to analyze the page content.
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.

playwright is a skill published in the GitHub repository CodelyTV/agentic_programming-course (38 stars, last pushed 4mo ago), licensed MIT. It adds 37 tokens to every session and 204 once invoked, about $0.0002 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 2026-08-30.
