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.

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 →

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 | $0.00091 | $0.00791 |
| Opus 5.5 | $0.00036 | $0.00316 |
| Sonnet 5.5 | $0.00018 | $0.00158 |
| Haiku 4.5 | $0.00009 | $0.00079 |
Grade A, and why
playwright-cli 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
playwright-cli
playwright-cli is a token-efficient shell interface to Playwright. It keeps browser state across commands, exposes page snapshots with stable element refs such as e15, and prints the Playwright code it ran so the interaction can be converted into tests.
Core Workflow
playwright-cli open https://example.com
playwright-cli snapshot
playwright-cli click e15
playwright-cli fill e5 "[email protected]"
playwright-cli press Enter
playwright-cli close
Use refs from the latest snapshot by default. Re-run snapshot after navigation, major DOM changes, or a failed ref action. Use CSS selectors or Playwright locators only when refs are unavailable or unstable.
Operating Rules
- Discover exact syntax with
playwright-cli --helpandplaywright-cli <command> --help; the CLI changes quickly. - Use
--rawwhen piping values into other tools. Use--jsononly if the installed CLI advertises it. - Use named sessions with
-s=<name>for concurrent or long-lived work. - Use
open --persistentonly when disk-persisted cookies/storage are needed. - Prefer
attach --cdp=chrome,attach --cdp=msedge, orattach --cdp=http://127.0.0.1:9222when the task needs an existing browser/session. - Close sessions when finished. Reserve
close-allandkill-allfor cleanup of stale sessions.
Common Tasks
playwright-cli open https://example.com --browser=chrome
playwright-cli snapshot --depth=4
playwright-cli screenshot --filename=page.png
playwright-cli console warning
playwright-cli requests --filter="/api/.*"
playwright-cli request-headers 3
playwright-cli run-code "async page => await page.context().grantPermissions(['geolocation'])"
playwright-cli tracing-start
playwright-cli tracing-stop
For a broader command map, read references/cli-reference.md.
Playwright Test Debugging
When a Playwright test fails, prefer the CLI debug workflow:
PLAYWRIGHT_HTML_OPEN=never npx playwright test --debug=cli
# wait for "Debugging Instructions", then attach to the printed session
playwright-cli attach tw-abcdef

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-cli is a skill published in the GitHub repository appautomaton/webmaton (20 stars, last pushed 1mo ago), licensed MIT.
