Manage agentic work across repositories with durable workbases
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe automatic postinstall mutation installs a first-party package-owned agent extension, which warrants a warning under the agent integration policy. The inspected behavior is package-aligned and does not establish a concrete attack.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Installing the npm package triggers postinstall.
Impact
Pi loads the installed extension and it can add Agency workbase context and instructions to agent sessions.
Mechanism
The hook copies the bundled extension to `~/.pi/agent/extensions/agency.ts`, where it can register agent hooks and invoke the Agency CLI.
AI rationale
The automatic postinstall mutation installs a first-party package-owned agent extension, which warrants a warning under the agent integration policy. The inspected behavior is package-aligned and does not establish a concrete attack.
Evidence
~/.pi/agent/extensions/agency.ts
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook automatically runs the Pi extension installer.
- The installer copies the package-owned extension into the user's global Pi extensions directory.
- That extension calls the Agency CLI for workbase context and registers agent hooks.
Evidence against
- The extension is copied from this package and targets its own `.pi/agent/extensions` location.
- The inspected extension behavior uses Agency context to add workbase instructions; no credential forwarding or unrelated network recipient was identified.
