AI Security Review
scanned 13h ago · by lpm-firewall-aiThe postinstall makes project-level agent configuration changes without a separate setup command, creating residual agent extension lifecycle risk. Source inspection ties the changes to a first-party schema guard and project-specific conditions, with no confirmed malicious payload or data transfer.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package in a project with Suppa schema code or a Suppa dependency, unless a skip condition applies.
Impact
The package changes agent behavior and project controls without a separate affirmative setup command; the inspected source does not establish credential exposure or destructive effects.
Mechanism
The postinstall invokes an installer that adds Claude Code hooks and managed agent instructions, alongside project Git, CI, and package configuration.
AI rationale
The postinstall makes project-level agent configuration changes without a separate setup command, creating residual agent extension lifecycle risk. Source inspection ties the changes to a first-party schema guard and project-specific conditions, with no confirmed malicious payload or data transfer.

Decision evidence
public snapshotAI called this Suspicious at 85.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package postinstall automatically runs a script that can configure the consuming project.
- When it finds Suppa schema code, the installer writes Claude Code hooks and adds managed sections to project agent instructions.
- The installer also changes project Git, CI and package settings as part of the same automatic setup.
Evidence against
- The postinstall skips global installs, CI, the package's own install, and projects without Suppa schema code or a Suppa dependency.
- The installed hooks run the package's entity-code guard; the inspected setup does not establish credential collection, external transmission, or destructive behavior.
