AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall hook performs first-party package-owned agent extension setup, which warrants a warning under the agent integration policy. The inspected code does not establish a broader attack chain or malicious payload.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm postinstall; later, a Pi agent starts in a matching Agency workbase.
Impact
This changes the Pi agent's loaded behavior using workbase instructions. No concrete malicious action was identified in the inspected extension.
Mechanism
The lifecycle script copies the bundled extension into the user's Pi extensions directory. The extension reads the workbase instruction file and appends its contents to the system prompt.
AI rationale
The postinstall hook performs first-party package-owned agent extension setup, which warrants a warning under the agent integration policy. The inspected code does not establish a broader attack chain or malicious payload.
Evidence
~/.pi/agent/extensions/agency.ts
Decision evidence
public snapshotAI called this Suspicious at 97.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook automatically runs the package's Pi extension installer.
- The installer copies the bundled extension into the user's Pi agent extensions directory.
- The extension reads workbase instructions and adds them to Pi's system prompt when an agent starts.
- IntegrationService also targets workbase instruction and OpenCode configuration files; its agent setup is part of the package's integration behavior.
Evidence against
- The extension obtains context through the package's own agency command and uses that context to locate workbase instructions.
- The inspected extension behavior shows no credential collection, remote endpoint, or remote payload execution.
