PAI Knowledge OS — Personal AI Infrastructure with federated memory and project management

AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection found a prepublish build script and user-confirmed CLI hook installation, not an automatic install-time attack. The flagged hook locations align with local PAI configuration and project-note handling; no malicious behavior was established.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The hook setup prompt is reached through the CLI setup flow; the user can decline it.

Impact

No concrete malicious effect was established from the inspected source.

Mechanism

The observed hook files load local PAI configuration or locate project notes. The installer asks whether to install lifecycle hooks before proceeding.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest has a prepublish build hook, not an npm install hook.
The flagged hook files load PAI environment configuration from local .env files; the cited locations show no transmission or agent-control write.
Project-context code checks project-local and matching Claude project notes locations.
The bundled CLI asks before installing lifecycle hooks and skips installation when declined.
