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 | $0.00043 | $0.00888 |
| Opus 5.5 | $0.00017 | $0.00355 |
| Sonnet 5.5 | $0.00009 | $0.00178 |
| Haiku 4.5 | $0.00004 | $0.00089 |
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 1mo 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright CLI Skill
Drive a real browser from the terminal using @playwright/cli.
Treat this skill as CLI-first automation. Do not pivot to @playwright/test unless the user explicitly asks for test files.
Prerequisite check (required)
Before proposing commands, check whether npx is available:
command -v npx >/dev/null 2>&1
If it is not available, pause and ask the user to install Node.js/npm (which provides npx). Provide these steps verbatim:
# Verify Node/npm are installed
node --version
npm --version
# If missing, install Node.js/npm, then:
npm install -g @playwright/cli@latest
playwright-cli --help
Once npx is present, proceed with the CLI commands. A global install of @playwright/cli is optional but helpful if used frequently.
Quick start
Use npx @playwright/cli to run commands:
npx @playwright/cli open https://playwright.dev --headed
npx @playwright/cli snapshot
npx @playwright/cli click e15
npx @playwright/cli type "Playwright"
npx @playwright/cli press Enter
npx @playwright/cli screenshot
If the user prefers a global install, this is also valid:
npm install -g @playwright/cli@latest
playwright-cli --help
Core workflow
- Open the page.
- Snapshot to get stable element refs.
- Interact using refs from the latest snapshot.
- Re-snapshot after navigation or significant DOM changes.
- Capture artifacts (screenshot, pdf, traces) when useful.
Minimal loop:
npx @playwright/cli open https://example.com
npx @playwright/cli snapshot
npx @playwright/cli click e3
npx @playwright/cli snapshot
When to snapshot again
Snapshot again after:
- navigation
- clicking elements that change the UI substantially
- opening/closing modals or menus
- tab switches
Refs can go stale. When a command fails due to a missing ref, snapshot again.
Recommended patterns
Form fill and submit
npx @playwright/cli open https://example.com/form
npx @playwright/cli snapshot
npx @playwright/cli fill e1 "[email protected]"
npx @playwright/cli fill e2 "password123"
npx @playwright/cli click e3
npx @playwright/cli snapshot
What ships with it
7 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 is a skill published in the GitHub repository miptah21/skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 43 tokens to every session and 888 once invoked, about $0.0002 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 2026-09-03.
