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:** 0.20.0 - **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. Install-time scripts modify Pi agent configuration and install Maestro workflow resources. No source-confirmed exfiltration or remote payload chain was found in the inspected hooks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-13T01:58:47.717Z - **Finished:** 2026-08-13T01:59:50.696Z - **Download time:** 509 ms - **Static scan time:** 4953 ms - **AI review time:** 57515 ms - **Total time:** 62979 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:** Install-time scripts modify Pi agent configuration and install Maestro workflow resources. No source-confirmed exfiltration or remote payload chain was found in the inspected hooks. - **Trigger:** npm postinstall - **Impact:** Unconsented agent-extension lifecycle configuration changes - **Evidence paths:** package.json, scripts/configure-keybindings.mjs, scripts/install-workflows.mjs, scripts/register-companion-packages.mjs, src/session/cli-adapter.ts, .pi/skills/team-swarm/scripts/test\_aco.py - **Review source:** ai\_review - **Reviewed:** 2026-08-13T01:59:50.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Registers Pi companion packages, changes a keybinding, and installs workflows - **Rationale:** This is a real install-time AI-agent extension setup risk, but the inspected code is package-aligned and does not show a concrete malicious chain. Warn rather than block under the lifecycle policy. - **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:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** npm postinstall runs three setup scripts., Postinstall writes Pi agent keybindings., Postinstall registers companion extensions in Pi settings., Postinstall installs Maestro workflows under the user home directory. - **Evidence against:** Inspected lifecycle scripts contain no network request or credential collection., Companion registration is limited to named dependencies and preserves unowned overrides., No concrete exfiltration, remote payload execution, or destructive chain was found. ## Affected versions and remediation This report applies to pi-maestro-flow@0.20.0. - Review the evidence and your use of pi-maestro-flow@0.20.0 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.
