Manage agentic work across repositories with durable workbases

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The postinstall hook automatically installs a package-owned agent extension, which can augment Pi's system prompt with workbase context. This is a guarded first-party extension setup risk, so warn without blocking publication.

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 triggers postinstall; later Pi sessions trigger the extension callbacks.

Impact

The extension can influence agent behavior with workbase instructions and context. The inspected code supports package-owned integration setup, with no confirmed credential exfiltration or other attack.

Mechanism

The installer copies the extension to the user's Pi agent extension path. The extension reads the workbase instruction file and appends it and Agency context to the system prompt.

AI rationale

Evidence

package.jsonscripts/install-pi-extension.tspi-extensions/agency.tssrc/services/IntegrationService.ts

Decision evidence

public snapshot

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

Evidence for warning

The postinstall hook runs the Pi extension installer automatically.
The installer copies the package-owned extension into the user's Pi agent extensions directory.
The extension reads workbase instructions and adds workbase context to the agent's system prompt.
Integration code also identifies project-level agent and OpenCode configuration paths.

Evidence against

The installer uses exclusive copy on first install and only updates an existing extension when its ownership marker and content hash match.
The inspected extension code shows no network request or credential forwarding.
