⚠ 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 under ~/.crouter/runtime, and Claude command mirroring happens later inside the pi extension.

Static reason

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

Trigger

npm postinstall and later pi extension resource discovery

Impact

Install changes the package runtime directory. It does not by itself rewrite a foreign agent control surface. A clean verdict still cannot be published because the required citation set exceeds the citation cap.

Mechanism

Postinstall calls install-runtime, which packs this tree and runs npm ci --ignore-scripts in the runtime home. The Claude extension indexes user command files only when the pi extension is loaded.

AI rationale

Inspected install and agent paths do not show an independent block or warn chain, but mark_clean is disallowed because 16 required citations exceed the 8-citation limit. The review is therefore unresolved rather than a finding of malware.

Decision evidence

public snapshot

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

AI review observations

Required clean citation coverage lists 16 paths but sourceCitations allows at most 8, so a mark_clean result cannot be finalized.
package.json postinstall runs scripts/postinstall.mjs, which installs a runtime generation under the package runtime home.
