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 | $0.00035 | $0.03956 |
| Opus 5.5 | $0.00014 | $0.01582 |
| Sonnet 5.5 | $0.00007 | $0.00791 |
| Haiku 4.5 | $0.00003 | $0.00396 |
Grade A, and why
vasu-playwright-utils 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 2mo 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vasu-playwright-utils
A Playwright TypeScript utility library that simplifies browser automation with reusable helper functions for actions, assertions, locators, element queries, page management, and API requests.
Setup Requirement
Before using any utility, you must call setPage(page) with the Playwright Page instance:
import { setPage } from 'vasu-playwright-utils';
// In test setup or beforeEach:
setPage(page);
Import Patterns
Main export (all utilities)
import { click, fill, expectElementToBeVisible, getLocator } from 'vasu-playwright-utils';
Subpath exports (tree-shakable)
import { click, fill, clickAndNavigate } from 'vasu-playwright-utils/action-utils';
import { expectElementToBeVisible, expectPageToHaveURL } from 'vasu-playwright-utils/assert-utils';
import { getLocator, getLocatorByRole, getLocatorByText } from 'vasu-playwright-utils/locator-utils';
import { getText, isElementVisible, waitForElementToBeVisible } from 'vasu-playwright-utils/element-utils';
import { gotoURL, switchPage, getPage, setPage } from 'vasu-playwright-utils/page-utils';
import { getRequest, postRequest } from 'vasu-playwright-utils/api-utils';
import { ClickOptions, FillOptions } from 'vasu-playwright-utils/types';
Core Pattern
Most functions accept string | Locator as their first argument (the input parameter). This means you can pass either a CSS/XPath selector string or a Playwright Locator object.
Action functions enforce visibility by default (onlyVisible: true). Override with { onlyVisible: false }.
Most functions accept an optional options object as the last parameter, extending Playwright's native options with:
onlyVisible?: boolean- Filter to visible elements only (default:truefor actions)stable?: boolean- Wait for element position to stabilize before actingloadState?: WaitForLoadStateOptions- Wait for load state after navigation actionssoft?: boolean- Use soft assertions (won't stop test on failure)
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.

vasu-playwright-utils is a skill published in the GitHub repository vasu31dev/playwright-ts-lib (25 stars, last pushed 7mo ago), licensed MIT. It adds 35 tokens to every session and 3,956 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 2026-08-30.
