AI Security Review
scanned 24d ago · by lpm-firewall-aiSource inspection found a postinstall hook for repository subpackage setup, guarded to exit in node_modules installations. The launcher, bounded resource collection, and frontend configuration loading did not establish a malicious attack surface.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Package installation invokes the postinstall hook; the reviewed script exits when its directory is under node_modules.
Impact
The inspected behavior supports repository setup and bounded resource collection; no confirmed malicious effect was established.
Mechanism
In a repository checkout, the script installs dependencies for package subdirectories and may build the autocomplete subpackage.
AI rationale
Source inspection found a postinstall hook for repository subpackage setup, guarded to exit in node_modules installations. The launcher, bounded resource collection, and frontend configuration loading did not establish a malicious attack surface.

Decision evidence
public snapshotAI called this Clean at 89.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall script exits immediately when installed under node_modules, then performs npm installs only for repository subdirectories.
- The launcher starts the package’s bundled server entry with the caller’s arguments and environment.
- The resource service runs bounded system-resource commands with a timeout.
- The frontend bundle dynamically loads a user-selected Jupyter configuration file.
Evidence against
- The manifest has a postinstall hook, but the published-package path is guarded from its repository setup behavior.
- Inspected network behavior checks the npm registry for an update and reports the result; no automatic update install was found.
