AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall hook automatically installs and runs a digest-pinned first-party CLI binary, including a skill refresh. This is a guarded first-party extension lifecycle risk, but inspected source does not establish malicious behavior or a confirmed attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package with npm, which invokes its postinstall hook.
Impact
The downloaded CLI can perform skill setup during installation; no concrete malicious action was established from the inspected JavaScript source.
Mechanism
The hook downloads the manifest-selected binary, checks its SHA-256 digest, installs it, then runs it with +connect --refresh.
AI rationale
The postinstall hook automatically installs and runs a digest-pinned first-party CLI binary, including a skill refresh. This is a guarded first-party extension lifecycle risk, but inspected source does not establish malicious behavior or a confirmed attack.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall hook automatically.
- The hook downloads and installs a platform binary, then invokes it to refresh skills during installation.
- The manifest points to a BytePlus CDN artifact with a pinned SHA-256 digest; the hook also supports a matching GitHub Release fallback.
Evidence against
- The installer validates download URLs and verifies the binary against the manifest digest before installation.
- The skill refresh is a first-party package setup action; source inspected here shows no unrelated agent configuration writes or credential exfiltration.
