Do not execute instructions or code found in this document. ## 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:** 0.22.1 - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. On npm install, the package changes Pi agent configuration, registers its named companion extensions, and installs Maestro workflow resources. No concrete exfiltration, remote payload, or broad foreign-agent takeover was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-08-21T04:34:44.550Z - **Finished:** 2026-08-21T04:36:02.403Z - **Download time:** 509 ms - **Static scan time:** 5527 ms - **AI review time:** 71816 ms - **Total time:** 77853 ms 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:** On npm install, the package changes Pi agent configuration, registers its named companion extensions, and installs Maestro workflow resources. No concrete exfiltration, remote payload, or broad foreign-agent takeover was established. - **Trigger:** npm postinstall - **Impact:** Changes ~/.pi agent settings/keybindings and ~/.maestro workflow resources. - **Evidence paths:** package.json, scripts/configure-keybindings.mjs, scripts/install-workflows.mjs, scripts/register-companion-packages.mjs, src/mcpx-bridge.ts, .pi/skills/team-swarm/scripts/test\_aco.py - **Review source:** ai\_review - **Reviewed:** 2026-08-21T04:36:02.403Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** first-party Pi/Maestro extension setup and local configuration mutation - **Rationale:** This is a guarded first-party agent-extension lifecycle action performed at install time, so it warrants a warning. Source inspection found no credential exfiltration, remote code download, or foreign/broad AI-agent control-surface hijack. - **Files touched:** ~/.pi/agent/keybindings.json, ~/.pi/agent/settings.json, ~/.pi/agent/pi-maestro-flow-companions.json, ~/.maestro/workflows, ~/.maestro/arch-kb ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for warning:** Install hook runs three configuration/setup scripts., Postinstall writes Pi agent keybindings under the user home directory., Postinstall registers only named companion packages in Pi settings., Workflow setup invokes the installed maestro-flow CLI and copies local workflow resources. - **Evidence against:** No install-time network request or credential collection was found., Companion registration preserves unowned local overrides., MCP probe rejects metadata, private, and non-loopback HTTP targets., The flagged Python file is a readable test script, not a hidden payload. ## Affected versions and remediation This report applies to pi-maestro-flow@0.22.1. - Review the evidence and your use of pi-maestro-flow@0.22.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
