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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

- medium Rogue Agent · line 89 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 225 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00051 | $0.02035 |
| Opus 5.5 | $0.00020 | $0.00814 |
| Sonnet 5.5 | $0.00010 | $0.00407 |
| Haiku 4.5 | $0.00005 | $0.00203 |
Grade A, and why
playwright scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright MCP
The Playwright MCP server gives Claude Code agents direct browser control through 50+ tools that operate on the accessibility tree rather than screenshots. This enables fast, structured web interaction — navigating pages, clicking elements, filling forms, extracting content, and taking screenshots — without requiring vision models.
Installation
Claude Code (recommended)
# Default: bunx (preferred)
claude mcp add playwright -- bunx @playwright/mcp@latest
# Fallback: npx
claude mcp add playwright -- npx @playwright/mcp@latest
Verify the MCP server is connected by running /mcp in a Claude Code session.
Runtime Requirement
Bun or Node.js 18+ must be available. Add to your project or global mise.toml:
[tools]
bun = "latest"
See templates/mise.toml for the full template.
Configuration
Global (all sessions)
Add to ~/.claude.json to make Playwright available in every Claude Code session:
{
"mcpServers": {
"playwright": {
"command": "bunx",
"args": ["@playwright/mcp@latest"]
}
}
}
Per-Project
Add to .mcp.json in the project root for project-scoped configuration:
{
"mcpServers": {
"playwright": {
"command": "bunx",
"args": ["@playwright/mcp@latest"]
}
}
}
Configuration Flags
Pass flags after the package name in the args array or on the CLI:
claude mcp add playwright -- bunx @playwright/mcp@latest --headless --browser chromium
| Flag | Default | Description |
|---|---|---|
--browser |

--timeout-action |

What ships with it
2 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 vinnie357/claude-skills (27 stars, last pushed 14d ago), licensed MIT. It adds 51 tokens to every session and 2,035 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
