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 | $0.00069 | $0.01842 |
| Opus 5.5 | $0.00028 | $0.00737 |
| Sonnet 5.5 | $0.00014 | $0.00368 |
| Haiku 4.5 | $0.00007 | $0.00184 |
Grade A, and why
playwright-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to playwright-skill — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright Browser Automation
Write and execute focused Playwright scripts for the user's request. Prefer the skill's executor and helpers, but use the full Playwright API when needed.
Path resolution
This skill can be installed in several locations, so resolve its directory
first. Set SKILL_DIR to the directory containing this SKILL.md file, then run
the commands below as written:
export SKILL_DIR=<absolute path of the directory containing this SKILL.md>
export TMP_DIR="$(node -p 'require("node:os").tmpdir()')"
If shell state does not persist between commands, substitute the literal paths
for $SKILL_DIR and $TMP_DIR in each command instead.
Common installation paths:
- Plugin system:
~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill - Manual global:
~/.claude/skills/playwright-skill - Project-specific:
<project>/.claude/skills/playwright-skill
Workflow
-
For localhost work, detect running servers before writing a URL:
node -e "require('$SKILL_DIR/lib/helpers').detectDevServers().then(s => console.log(JSON.stringify(s)))"Use the only result automatically. Ask which URL to use when there are multiple results. Ask for a URL or offer to start a server when none exist.
-
Write reusable scripts to
$TMP_DIR/playwright-test-*.jsunless the user asks to save them in the project. UsePW_SCRIPT_DIRto preserve scripts. -
Use a visible browser by default. Use
headless: trueonly when requested or when the environment has no display. -
Put the target URL in a constant or environment variable.
-
Run scripts with
node "$SKILL_DIR/run.js" <script.js>. -
Report actions, failures, and artifact paths. Do not claim success without checking the resulting page.
Setup
Run once:
cd "$SKILL_DIR" && npm run setup
This installs Playwright and Chromium. Use cd "$SKILL_DIR" && npm run install-all-browsers when Firefox or WebKit is required.
Minimal example
What ships with it
5 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.
