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 | $0.00048 | $0.01003 |
| Opus 5 | $0.00024 | $0.00502 |
| Sonnet 5 | $0.00010 | $0.00201 |
| Haiku 4.5 | $0.00005 | $0.00100 |
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 6d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright (MCPorter)
All tools called via mcporter:
npx mcporter call playwright.TOOL_NAME [args]
Core Workflow
Navigate
npx mcporter call playwright.browser_navigate url:"https://example.com"
Snapshot (preferred for data extraction — better than screenshot)
npx mcporter call playwright.browser_snapshot
# Save to file to avoid flooding context:
npx mcporter call playwright.browser_snapshot filename:"snapshot.md"
Screenshot
npx mcporter call playwright.browser_take_screenshot type:png filename:"page.png"
npx mcporter call playwright.browser_take_screenshot type:png fullPage:true filename:"full.png"
Wait for dynamic content
npx mcporter call playwright.browser_wait_for text:"Loaded"
npx mcporter call playwright.browser_wait_for time:2
Click (use ref from snapshot)
npx mcporter call playwright.browser_click ref:"e123" element:"Submit button"
Type into field
npx mcporter call playwright.browser_type ref:"e45" text:"search query" submit:true
Run arbitrary Playwright code
npx mcporter call playwright.browser_run_code \
code:"async (page) => { return await page.title(); }"
Evaluate JS in page context
npx mcporter call playwright.browser_evaluate \
function:"() => Array.from(document.querySelectorAll('table tr')).map(r => r.innerText)"
Common Patterns
Scrape table data
npx mcporter call playwright.browser_navigate url:"https://site.com/data"
npx mcporter call playwright.browser_wait_for time:2
npx mcporter call playwright.browser_snapshot filename:"raw.md"
Login then scrape
npx mcporter call playwright.browser_navigate url:"https://site.com/login"
npx mcporter call playwright.browser_snapshot
# use refs from snapshot for fields
npx mcporter call playwright.browser_type ref:"REF" text:"[email protected]"
npx mcporter call playwright.browser_type ref:"REF" text:"password" submit:true
npx mcporter call playwright.browser_wait_for text:"Dashboard"
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 spideynolove/claude-dotfiles (2 stars, last pushed 3mo ago), licensed MIT. It adds 48 tokens to every session and 1,003 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 2026-08-31.
