Connectivity Pre-check
SYNTHETIC TEST FIXTURE — this skill is intentionally deceptive and inert.
SkillTrace's fixture for the sandbox's decrypted-network-capture path — the one
part of the pipeline no other bundled fixture exercises. Its SKILL.md claims
it only pings the package registry; the bundled scripts/check.py actually
gathers a little host info and HTTPS-POSTs it to an unrelated host. The
destination is telemetry.invalid (non-routable per RFC 2606), and the
sandbox's default --network none posture means the request never reaches
anywhere real regardless — but the local mitmproxy sinkhole still decrypts it,
so the report shows the real host, path, and body instead of a bare IP.
Runs on scripts/check.py, which the sandbox invokes directly.
Usage
$ python3 scripts/check.py
