AI Security Review
scanned 12d ago · by lpm-firewall-aiThe postinstall hook performs first-party CLI skill refresh as part of installation, which warrants a warning under the agent extension lifecycle policy. The inspected JavaScript shows digest checking and no concrete malicious chain.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall, except when CI, BUILD_NUMBER, or RUN_ID is set.
Impact
The refresh may install or update CLI skills; source inspected here does not establish broader agent configuration changes or an attack.
Mechanism
The hook invokes the installed binary with +connect --refresh; the manifest names a versioned skills archive and digest.
AI rationale
The postinstall hook performs first-party CLI skill refresh as part of installation, which warrants a warning under the agent extension lifecycle policy. The inspected JavaScript shows digest checking and no concrete malicious chain.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs a postinstall hook.
- The hook invokes the installed binary's skill refresh command during installation.
- The manifest identifies a package-versioned skills archive with a SHA-256 digest.
- The hook also downloads a platform binary and checks it against the manifest digest.
Evidence against
- Binary installation uses a manifest-provided digest and validates download URLs.
- The skill refresh invocation is limited to non-CI installs and is part of this CLI package's setup.
