What it costs to keep this loaded
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 | $0.00047 | $0.00984 |
| Opus 5 | $0.00023 | $0.00492 |
| Sonnet 5 | $0.00009 | $0.00197 |
| Haiku 4.5 | $0.00005 | $0.00098 |
Grade A, and why
mcp-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 10d 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.

Playwright MCP
Overview
This skill enables browser automation using Playwright through MCP. Playwright provides powerful browser control capabilities including navigation, element interaction, screenshots, and form handling.
When to Use This Skill
- Navigating and interacting with web pages
- Taking screenshots of web content
- Filling out forms and submitting data
- Testing web applications
- Extracting information from web pages
- Automating repetitive browser tasks
Quick Start Workflow
- Navigate to a page:
browser_navigate - Take a snapshot to get element refs:
browser_snapshot - Interact with elements using refs from snapshot:
browser_click,browser_type
Core Tools
Navigation
browser_navigate - Navigate to a URL
mcp__playwright__browser_navigate({ url: "https://example.com" })
browser_navigate_back - Go back to previous page
mcp__playwright__browser_navigate_back({})
Page Analysis
browser_snapshot - Get accessibility tree (preferred for interaction)
mcp__playwright__browser_snapshot({})
browser_take_screenshot - Capture visual screenshot
mcp__playwright__browser_take_screenshot({
type: "png",
fullPage: true,
filename: "screenshot.png"
})
Element Interaction
browser_click - Click an element (requires ref from snapshot)
mcp__playwright__browser_click({
element: "Submit button",
ref: "button[ref='submit']"
})
browser_type - Type text into an element
mcp__playwright__browser_type({
element: "Search input",
ref: "input[ref='search']",
text: "search query",
submit: true
})
browser_hover - Hover over an element
mcp__playwright__browser_hover({
element: "Menu item",
ref: "li[ref='menu']"
})
Form Handling
browser_fill_form - Fill multiple form fields
mcp__playwright__browser_fill_form({
fields: [
{ name: "Username", type: "textbox", ref: "input[name='user']", value: "john" },
{ name: "Remember", type: "checkbox", ref: "input[name='remember']", value: "true" }
]
})
What ships with it
1 file 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.

mcp-playwright is a skill published in the GitHub repository s-hiraoku/vscode-sidebar-terminal (21 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 984 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 2026-09-01.
