Manage agentic work across repositories with durable workbases

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The postinstall hook performs first-party agent extension setup in the user’s Pi directory, which warrants a warning under the agent integration policy. Source inspection found ownership safeguards and no concrete attack behavior.

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 npm package triggers its postinstall hook.

Impact

The extension can add workbase instructions to Pi agent prompts. No network transfer or malicious control behavior was identified in the inspected source.

Mechanism

The hook copies the bundled extension and records an ownership hash; subsequent replacement and removal are limited to files verified as package-owned.

AI rationale

Evidence

package.jsonscripts/install-pi-extension.tspi-extensions/agency.tssrc/services/IntegrationService.tssrc/commands/integration.tsuser home .pi/agent/extensions/agency.tsuser home .pi/agent/extensions/agency.ts.agency-managed.json

Decision evidence

public snapshot

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

Evidence for warning

The postinstall hook automatically installs the package’s Pi extension; preuninstall invokes its removal.
The installer copies the bundled extension to the user’s Pi extensions directory and records ownership; it skips existing files it cannot verify as owned.
The wider workbase and OpenCode integration sync is exposed as an explicit CLI subcommand.
The integration service targets project workbase configuration, including agent instructions and OpenCode files.

Evidence against

The installer refuses to replace a symlink or a file whose contents do not match its ownership record, and uninstall removes only a matching owned file.
The bundled extension reads workbase instructions and adds them to the agent prompt; inspected source showed no network endpoint.
