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 falls under the warning policy for agent extension lifecycle setup. Source inspection found ownership checks and no concrete attack chain supporting a block.

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 triggers postinstall.

Impact

The extension becomes available to the Pi agent; no confirmed credential theft, exfiltration, or broad control-surface mutation was identified.

Mechanism

The hook copies the bundled Agency extension to the user's Pi extensions directory, with ownership checks for existing files.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The install lifecycle automatically runs the package-owned extension installer; uninstall also invokes its removal mode.
The installer copies this package's Agency extension into the user's Pi agent extensions directory and tracks file ownership.
Uninstallation removes the extension only when its ownership marker and content hash match.
The inspected integration target identifies workbase-local agent and OpenCode configuration paths; no foreign broad agent-control mutation was established there.

Evidence against

The installer skips an existing extension it cannot prove ownership of and only updates a matching owned copy.
Integration configuration synchronization is exposed through a service method rather than shown as part of the npm install hook.
