Manage agentic work across repositories with durable workbases
AI Security Review
scanned 9d ago · by lpm-firewall-aiThe postinstall hook automatically adds a package-owned extension to the user’s global Pi configuration, creating an agent extension lifecycle risk. The installer limits replacement of existing files, and the inspected extension behavior does not establish a malicious attack.
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 with lifecycle scripts enabled.
Impact
Pi sessions can receive Agency workbase instructions and context without a separate extension setup command. This guarded first-party extension setup warrants a warning, but no concrete attack was established.
Mechanism
The hook copies the package-owned extension into the global Pi extensions directory, then Pi loads it in later sessions.
AI rationale
The postinstall hook automatically adds a package-owned extension to the user’s global Pi configuration, creating an agent extension lifecycle risk. The installer limits replacement of existing files, and the inspected extension behavior does not establish a malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs its Pi extension installer from its postinstall hook.
- The installer targets the user’s global Pi extension directory and copies the package’s extension there during installation.
- For an existing extension, the installer skips changes unless it can verify the file is package-owned and unchanged.
- The extension adds Agency workbase context and instructions to later Pi system prompts.
- IntegrationService inspects workbase-scoped agent configuration; its sync path is a separate service operation.
Evidence against
- The installer preserves existing extensions it cannot verify as package-owned and unchanged.
- The inspected extension source establishes no credential transfer or malicious action.
