Pruébalo

Usando "browser-fingerprint-audit". Audit a temporary browser and summarize only failed checks.

Resultado esperado:

Score: 82 of 100. Classification: Suspicious.
Failed check: navigator.webdriver. The automation flag is enabled.
Failed check: timezone mismatch. The browser timezone differs from the IP-derived timezone.

Usando "browser-fingerprint-audit". Run an offline audit and explain the coverage.

Resultado esperado:

The audit completed using local browser signals only. It evaluated 32 checks and skipped eight cross-layer network checks.

Usando "browser-fingerprint-audit". Explain why a headless browser received a low score.

Resultado esperado:

The low score reflects observable headless and automation signals. It measures profile consistency and does not predict a specific website response.

Three static findings are confirmed. Two commands execute a pinned npm package, while the default network path sends request metadata to liarjs.dev. Other detections are markdown or documented local behavior, but optional CDP attachment can access an existing browser session.

Existing Browser Session Access

The optional CDP workflow can drive an existing browser, open tabs, and read page state. Authenticated session content may therefore become accessible.

The skill explicitly states that CDP attachment can open a tab and read page state in the user's session.

Ruby/shell backtick execution

```bash

The Bash block directs the agent to run npx liarjs@0.3, which downloads or executes an external npm package and launches a browser.

Medio

SKILL.md:82-84

Ruby/shell backtick execution

```bash

The Bash block runs npx liarjs@0.3 and attaches it to a CDP endpoint, executing an external package against a browser session.

Hardcoded URL

- The network half works by having the browser under test fetch `https://liarjs.dev/api/net.json`,

The default online scan fetches liarjs.dev and exposes request metadata including IP, ASN, headers, HTTP, TLS, and ClientHello characteristics.

Lo que puedes crear

Review an automation profile

Identify contradictory browser signals before using a controlled automation environment.

Investigate fingerprint drift

Examine canvas, graphics, font, timezone, and network mismatches after an environment change.

Assess privacy exposure

Run offline checks to understand which local browser characteristics are observable.

Prueba estos prompts

Run a standard audit

Run the default browser fingerprint audit. Report the score, classification, failed check identifiers, and concise explanations.

Run an offline audit

Run the browser fingerprint audit in offline mode. Explain every failed local check and clearly list the skipped network checks.

Inspect selected signal groups

Audit this browser and focus on canvas, WebGL, WebGPU, fonts, WebRTC, and timezone. Explain contradictions and likely environmental causes.

Audit an existing browser session

Audit my running Chrome through the CDP endpoint I provide. Confirm the endpoint and session access risk before attaching.

Mejores prácticas

Use offline mode when external network comparison is unnecessary.
Prefer a temporary browser profile unless the existing session is the explicit audit subject.
Compare unusual environments with a saved baseline instead of relying only on an absolute score.

Evitar

Do not attach to an existing browser without explicit approval and endpoint confirmation.
Do not treat a high consistency score as proof that every website will trust the browser.
Do not send production browsing sessions or sensitive pages to untrusted endpoints.

Preguntas frecuentes

What does the score measure?

It measures consistency among browser signals and the network view. It does not predict every website's detection decision.

Does the standard audit make a network request?

Yes. The online mode contacts liarjs.dev for IP, ASN, HTTP, TLS, header, and ClientHello observations.

Can the audit run without sending data externally?

Yes. Offline mode runs 32 browser-only checks and skips eight network comparison checks.

Does the default scan use my browser profile?

No. It launches a fresh temporary profile and removes that profile after the scan.

Can it scan an already running browser?

Yes, through an approved CDP endpoint. That access can open tabs and read page state in the existing session.

Why can a legitimate environment receive a low score?

Headless mode, datacenter networks, unusual fonts, locale settings, and browser version changes can create real consistency failures.
