Security Analysis
medium confidenceThe skill's code and instructions largely match a stealth Playwright wrapper that fetches residential proxy credentials from an external service, but it omits declaring required credentials, promotes auto-fetch/auto-purchase behavior to an external endpoint, and gives agents network access to obtain sensitive proxy credentials — inconsistencies that warrant caution.
The name/description match the included code: a Playwright wrapper that spoofs device fingerprints and uses residential proxies. That capability justifies proxy credentials and Playwright. However the package metadata lists no required env vars/credentials even though the SKILL.md and code expect many HB_PROXY_* / PROXY_* env vars (sensitive). Also README/SKILL.md claim a 'free trial, no signup' auto-fetch and that agents can 'auto-purchase' — features not declared in registry metadata and which expand the skill's effective capabilities beyond the manifest.
The runtime instructions and the script instruct the agent to call getTrial(), which performs an HTTPS request to https://humanbrowser.cloud/api/trial and then sets proxy credential env vars in-process. The SKILL.md encourages auto-fetching credentials and external purchase flows. The skill therefore directs network actions to an external service and will populate sensitive credentials automatically — behavior beyond simple local browser automation and not surfaced in the manifest.
There is no installer that downloads arbitrary archives; the skill is instruction/code-only and relies on the consumer to have Playwright installed (peerDependency). No suspicious download/install steps are present in the manifest.
The skill expects/uses multiple sensitive env vars (HB_PROXY_USER, HB_PROXY_PASS, HB_PROXY_SESSION, PROXY_*, HB_NO_PROXY) but the registry metadata declares none as required. The script will set env vars via getTrial(), and will read from various env var names (legacy names included). Requesting or populating proxy credentials is plausible for a proxy-using browser, but the lack of declared required creds in metadata and the skill's ability to fetch credentials from an external endpoint are disproportionate and should be made explicit to users.
The skill does not request always:true and doesn't modify other skills' configs. However it does permit autonomous invocation (platform default) and performs network calls to obtain credentials and (per README claims) supports agent-initiated purchases — combining autonomous invocation with credential-fetch and external purchase claims increases blast radius and should be considered when granting the skill runtime privileges.
Guidance
This skill is a coherent stealth browser wrapper, but it reaches out to an external service (humanbrowser.cloud) to auto-provision proxy credentials and advertises agent-initiated purchases — behaviors that are not declared in the registry metadata. Before installing: 1) Review the full scripts/browser-human.js to confirm what network calls it makes (getTrial() does an HTTPS GET to /api/trial). 2) Decide whether you trust humanbrowser.cloud; if not, do not call getTrial() and set HB_NO_PROXY=1 for local testing. 3) Do not store payment methods or allow autonomous agent actions that could purchase services; restrict the skill's ability to act autonomously if your platform allows it. 4) If you will use real proxy credentials, provide them manually (avoid auto-fetch) and run the skill in an isolated environment. 5) Note legal/terms-of-service and ethical issues: bypassing anti-bot measures or accessing accounts may violate site terms or law. If you want more assurance, ask the publisher for provenance (who runs humanbrowser.cloud) and a security review of their endpoint before enabling automatic credential fetch or purchase flows.
