@north-light/crouter@0.3.353

⚠ Under review

Renamed: npm install -g @crouter/cli (github.com/crouton-labs/crouter)

crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 12d ago · by lpm-firewall-ai

No confirmed attack surface was established. The install hook stages this package's own runtime and does not select another release of @north-light/crouter. A clean verdict cannot be finalized because required citation coverage exceeds the eight-citation limit.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Citation capacity blocks mark_clean after source inspection; npm postinstall is the relevant install trigger that was checked.

Impact

Install impact is local runtime staging. Remaining required files were not all citable, so residual behavior there is unresolved rather than confirmed compromise.

Mechanism

postinstall calls install-runtime, which npm-packs the current tree and runs npm ci --ignore-scripts under the package runtime home. Agent path handling sits in an extension file that postinstall does not load.

AI rationale

Inspected install and agent entrypoints do not independently show malware, credential theft, or an unconsented foreign agent-control write. A clean result is blocked only because sixteen required citations cannot fit in eight slots, so the review stays unresolved.

Decision evidence

public snapshot

AI called this Manual Review at 62.0% confidence as Unknown with medium false-positive risk.

AI review observations

Clean publication cannot be recorded: the review requires 16 distinct source citations and the schema allows at most 8.
