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 | $0.00027 | $0.00525 |
| Opus 5.5 | $0.00011 | $0.00210 |
| Sonnet 5.5 | $0.00005 | $0.00105 |
| Haiku 4.5 | $0.00003 | $0.00052 |
Grade A, and why
playwright-browser 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 25d 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 it actually says
node $SKILL_DIR/run.js /tmp/playwright-task.js
For inline code (variables are auto-injected, see below):
node $SKILL_DIR/run.js "const b = await chromium.launch(); const p = await b.newPage(); await p.goto('http://localhost:3000'); console.log(await p.title()); await b.close();"
$SKILL_DIR is where you loaded this file from.
Use { headless: false } when user wants to see the browser. You know when that is.
BASE_URL- from PLAYWRIGHT_BASE_URL env varCI_ARGS- browser args for CI (['--no-sandbox', '--disable-setuid-sandbox'])EXTRA_HEADERS- from PW_HEADER_NAME/VALUE or PW_EXTRA_HEADERSchromium,firefox,webkit,devices- from playwright
Example:
node $SKILL_DIR/run.js "
const browser = await chromium.launch({ args: CI_ARGS });
const page = await browser.newPage();
await page.goto(BASE_URL || 'http://localhost:3000');
console.log(await page.title());
await browser.close();

What ships with it
3 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.

playwright-browser is a skill published in the GitHub repository TechNickAI/ai-coding-config (24 stars, last pushed 26d ago), licensed MIT. It adds 27 tokens to every session and 525 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-22.

Use when the user says 'write browser tests', 'test this page', 'playwright test', 'e2e test', 'end to end test', 'browser test', 'test the UI', or needs Playwright-based browser testing for a web application. Do NOT use for unit tests, API tests, or non-browser testing.
browser-automation
Playwright browser automation via MCP. Covers E2E testing, UI review, web scraping, screenshot capture, and general browser interaction. MCP-first — CLI is fallback only.
