## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 3.9.5
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package performs guarded first-party agent extension setup from an npm postinstall hook, which warrants a warning under the agent integration policy. Inspected source did not establish malicious execution, credential exfiltration, or another concrete attack.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The package postinstall installs a first-party Pi agent extension in the user's global extension directory. This is an agent extension lifecycle risk, but no separate malicious attack was established.

- **Trigger:** Installing the package through npm triggers postinstall.

- **Impact:** The extension becomes available to Pi and can affect agent context for Agency workbases; reviewed code showed no credential forwarding or unrelated network destination.

- **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T09:56:02.847Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The hook copies the bundled Agency extension into the global Pi extensions directory, preserving files it cannot verify as package-managed. The extension can query Agency context for recognized workbases.

- **Rationale:** The package performs guarded first-party agent extension setup from an npm postinstall hook, which warrants a warning under the agent integration policy. Inspected source did not establish malicious execution, credential exfiltration, or another concrete attack.

- **Files touched:** ~/.pi/agent/extensions/agency.ts, ~/.pi/agent/extensions/agency.ts.agency-managed.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The postinstall hook copies the package-owned extension into the user's global Pi extensions directory., The installer creates or updates the extension only when it can establish ownership of the existing file., The extension invokes Agency's own context command for discovered workbases; the inspected flow showed no external endpoint or credential forwarding., The requested integration code inspects workbase-local agent and OpenCode configuration paths.

- **Evidence against:** No concrete malicious behavior was identified in the reviewed installer or extension code.
