Manage agentic work across repositories with durable workbases
AI Security Review
scanned 9d ago · by lpm-firewall-aiThe automatic postinstall setup installs a package-owned Pi extension that can change the context supplied to future agent sessions. The inspected behavior supports an agent extension lifecycle warning, not a confirmed 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 through npm runs its postinstall hook.
Impact
Future Pi sessions may receive workbase instructions and Agency access guidance through the extension.
Mechanism
The installer copies the package-owned extension into the global Pi extensions directory. On later Pi sessions, the extension reads workbase instructions and appends them to the system prompt.
AI rationale
The automatic postinstall setup installs a package-owned Pi extension that can change the context supplied to future agent sessions. The inspected behavior supports an agent extension lifecycle warning, not a confirmed attack.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The flagged IntegrationService location targets the workbase-local .agency/AGENTS.md file; its sync behavior is separate from installation and is called through CLI operations.
- The package postinstall hook runs the Pi extension installer.
- The installer defaults to a global Pi extensions directory and copies the package-owned extension there.
- The extension handles Pi resource discovery and agent-start events, reading workbase instructions during agent startup.
- The extension appends those instructions and Agency access guidance to Pi's system prompt.
Evidence against
- Updates require a matching ownership marker and content hash; otherwise the installer leaves the existing extension unchanged.
- The inspected extension code shows prompt and skill integration, but does not establish credential theft or unrelated data transfer.
