Project subsystem bootstrapper CLI
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo concrete malicious install hook, payload execution, or credential theft was found. The explicit ability to modify Claude hook configuration is a meaningful agent-control capability, so it should be warned rather than blocked.
Static reason
No blocking static signals were detected.
Trigger
A user runs the Project Notebook hook installer or a CLI workflow that applies its hook projection.
Impact
Claude sessions can automatically invoke the local PJangler notebook hook bridge.
Mechanism
Writes recognized SessionStart and SessionEnd hook entries to Claude settings.
AI rationale
No concrete malicious install hook, payload execution, or credential theft was found. The explicit ability to modify Claude hook configuration is a meaningful agent-control capability, so it should be warned rather than blocked.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The manifest has CLI entrypoints and no preinstall, install, or postinstall hook.
- Board requests use supplied Plane credentials for the configured API endpoint.
- The MCP process uses standard input/output transport, not a network listener.
- The executable-looking code in the test path is a test fixture for environment-isolation checks.
- The shipped projector can explicitly install hooks into Claude settings, creating an agent-control capability.
Evidence against
- No automatic install-time execution, self-dependency, obfuscated payload, or credential exfiltration was found.
- The hook launcher validates its target and uses a restricted environment before invoking the local CLI.

•Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
