Project subsystem bootstrapper CLI
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has an explicit-user-command global agent hook installer, which warrants a warning under the control-surface policy. Static inspection found no install lifecycle, fixed credential redirection, or concrete malicious payload chain.
Static reason
No blocking static signals were detected.
Trigger
The user runs pj notebook migrate with --apply when the notebook hook repair is selected.
Impact
Future Claude session events can invoke the package's local notebook wrappers.
Mechanism
Projects owned session hooks into a global agent settings file.
AI rationale
The package has an explicit-user-command global agent hook installer, which warrants a warning under the control-surface policy. Static inspection found no install lifecycle, fixed credential redirection, or concrete malicious payload chain.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- An explicit notebook migration can install a global Project Notebook skill and project hooks.
- The installer targets the user's Claude settings file and invokes a hook projector.
- The projected settings run command hooks at SessionStart and SessionEnd.
Evidence against
- The manifest has no npm install lifecycle hook; prepublishOnly is publisher-side.
- Hook installation is reached through an explicit user command with --apply, not package installation.
- The hook wrappers use fixed local executables and fail open; no fixed exfiltration endpoint was found.
