Manage agentic work across repositories with durable workbases
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe postinstall hook performs global Pi extension setup, and that extension can affect agent skills and prompts when Agency context is present. Its conditional, package-owned behavior supports a warning for residual lifecycle risk, with no inspected evidence establishing a concrete attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package through npm triggers its postinstall hook.
Impact
The extension can influence Pi’s available skills and system prompt for Agency workbases without a separate extension-install confirmation.
Mechanism
The hook copies the package-owned extension into the global Pi extensions directory; the extension then responds to Pi session events when valid Agency workbase context is found.
AI rationale
The postinstall hook performs global Pi extension setup, and that extension can affect agent skills and prompts when Agency context is present. Its conditional, package-owned behavior supports a warning for residual lifecycle risk, with no inspected evidence establishing a concrete attack.
Evidence
package.jsonscripts/install-pi-extension.tspi-extensions/agency.tssrc/services/IntegrationService.ts
Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs the extension installer automatically after installation.
- The installer copies the package’s extension to the user’s global Pi extensions directory.
- The extension adds discovered workbase skills and can add workbase instructions to Pi’s system prompt.
- IntegrationService also inspects project-level agent configuration paths.
Evidence against
- The installer skips existing files it cannot verify as package-managed.
- The extension’s workbase behavior is conditional on finding valid Agency context.
