AI Security Review
scanned 6d ago · by lpm-firewall-aiThe postinstall hook automatically installs a package-owned agent extension globally, creating residual lifecycle risk even though the inspected extension provides local Agency integration. Project-level integrations are synchronized through an explicit CLI command, and the inspected sources did not establish a concrete attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package, followed by starting a Pi session.
Impact
Pi sessions can receive automatically supplied workbase context and instructions after package installation.
Mechanism
The postinstall script copies the extension into the global Pi extension directory, where session callbacks query local Agency context and add workbase instructions and access details to the system prompt.
AI rationale
The postinstall hook automatically installs a package-owned agent extension globally, creating residual lifecycle risk even though the inspected extension provides local Agency integration. Project-level integrations are synchronized through an explicit CLI command, and the inspected sources did not establish a concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 90.0% 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 extension directory when no file exists there; it skips existing files it cannot verify ownership of.
- The extension invokes the local Agency context command and adds workbase instructions and access details to Pi’s system prompt.
- The package’s workbase integration service targets project-local instruction and OpenCode files; its sync operation is exposed through an explicit CLI subcommand.
Evidence against
- The inspected extension code shows local context lookup and prompt/resource integration, with no network transfer identified.
- The inspected installer preserves existing unowned extensions, and project integration sync is command-driven.
