AI Security Review

scanned 12d ago · by lpm-firewall-ai

No confirmed attack was established. Install copies a sealed runtime under the package runtime home and skips dependency lifecycle scripts. The Claude path reference is in an extension loaded with the agent, and full clean citation coverage cannot fit in the citation limit.

Static reason

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

Trigger

npm postinstall, and later loading of the pi Claude command extension.

Impact

Install writes a package-owned runtime tree. Agent-directory behavior was not shown to run from the install hook, and remaining required files could not all be cited, so impact stays unresolved rather than a confirmed compromise.

Mechanism

postinstall spawns the local install-runtime script, which stages files under the crouter runtime home and runs npm ci --ignore-scripts. The extension file only declares paths under the user Claude and pi directories for command indexing.

AI rationale

The install hook stages this package's own runtime and disables nested lifecycle scripts, and the flagged Claude paths belong to an extension rather than an unconsented install-time control-surface write. A clean verdict cannot be published because the required citation list exceeds the eight-citation cap, 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

package.json postinstall runs scripts/postinstall.mjs, which installs a local runtime generation and then calls npm ci with --ignore-scripts inside that stage.
