Manage agentic work across repositories with durable workbases

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The postinstall hook installs a package-owned extension that modifies Pi’s agent context, a warning-level lifecycle risk. The inspected source did not establish a concrete malicious chain or credential exfiltration.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Installing the npm package, then starting a Pi agent in an Agency workbase.

Impact

The extension changes agent behavior within Agency workbases. This is a first-party agent extension setup risk; no concrete malicious behavior was identified.

Mechanism

The install hook copies the extension into the user’s Pi extensions directory; the extension invokes the agency CLI and augments the prompt with workbase instructions and context.

AI rationale

Evidence

package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts~/.pi/agent/extensions/agency.ts

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

package.json runs the Pi extension installer during postinstall and its uninstaller during preuninstall.
The installer copies the package-owned extension into the user’s Pi agent extensions directory.
The extension adds workbase instructions and context to Pi’s system prompt when a workbase is found.
IntegrationService also manages project integrations under .agency and .opencode paths.

Evidence against

The extension obtains context by running the agency CLI for the discovered workbase.
The inspected extension behavior reads workbase instructions and registers Pi event handlers; no credential forwarding or unrelated network recipient was identified.
The CLI integration command exposes explicit status and sync operations.
