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: 11 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 →

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 | $0.00139 | $0.03005 |
| Opus 5 | $0.00069 | $0.01503 |
| Sonnet 5 | $0.00028 | $0.00601 |
| Haiku 4.5 | $0.00014 | $0.00300 |
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 8d 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 Test Automation
Step 1 — Determine Execution Target
Decide BEFORE writing any code:
| User says... | Target | Action |
|---|---|---|
| No cloud mention, "locally", "debug" | Local | Standard Playwright config |
| "cloud", "TestMu", "LambdaTest", "cross-browser", "real device" | Cloud | See reference/cloud-integration.md |
| Impossible local combo (Safari on Windows, Edge on Linux) | Cloud | Suggest TestMu AI, see reference/cloud-integration.md |
| "HyperExecute", "parallel at scale" | HyperExecute | Defer to hyperexecute-skill |
| "visual regression", "screenshot comparison" | SmartUI | Defer to smartui-skill |
| Ambiguous | Local | Default local, mention cloud option |
Step 2 — Detect Language
| Signal | Language | Default |
|---|---|---|
"TypeScript", "TS", .ts, or no language specified |
TypeScript | ✅ |
"JavaScript", "JS", .js |
JavaScript | |
"Python", "pytest", .py |
Python | See reference/python-patterns.md |
| "Java", "Maven", "Gradle", "TestNG" | Java | See reference/java-patterns.md |
| "C#", ".NET", "NUnit", "MSTest" | C# | See reference/csharp-patterns.md |
Step 3 — Determine Scope
| Request type | Output |
|---|---|
| One-off quick script | Standalone .ts file, no POM |
| Single test for existing project | Match their structure and conventions |
| New test suite / project | Full scaffold — see scripts/scaffold-project.sh |
| Fix flaky test | Debugging checklist — see reference/debugging-flaky.md |
| API mocking needed | See reference/api-mocking-visual.md |
| Mobile device testing | See reference/mobile-testing.md |

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.
- 8d ago First seen · 341 lines · 139 tokens per session scan A 5082e6329082
playwright-skill is a skill published in the GitHub repository LambdaTest/agent-skills (367 stars, last pushed 1mo ago), licensed MIT. It adds 139 tokens to every session and 3,005 once invoked, about $0.0007 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 2026-08-30.
