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. Installation modifies Pi keybindings and registers companion extensions in Pi settings. The bundled browser bridge is a separate optional capability that requires manual Chrome loading. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-28T00:17:04.836Z - **Finished:** 2026-08-28T00:18:27.987Z - **Download time:** 503 ms - **Static scan time:** 7217 ms - **AI review time:** 75428 ms - **Total time:** 83151 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:** Installation modifies Pi keybindings and registers companion extensions in Pi settings. The bundled browser bridge is a separate optional capability that requires manual Chrome loading. - **Trigger:** npm installation runs the postinstall hook; the browser bridge requires explicit manual loading by the user. - **Impact:** Pi behavior and extension loading can change at install time; a manually loaded bridge can access browser data and control pages. - **Evidence paths:** package.json, scripts/configure-keybindings.mjs, scripts/install-workflows.mjs, scripts/register-companion-packages.mjs, optional/browser-bridge/manifest.json, optional/BROWSER-BRIDGE-SETUP.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T00:18:27.987Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall configuration mutation and optional privileged browser control. - **Rationale:** This is not concrete malware, but its install-time mutation of Pi settings and extension registration warrants a warning. The optional browser bridge adds a meaningful dangerous capability only after explicit user setup. - **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:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall hook changes Pi configuration, installs workflows, and registers companion packages., The installer writes a Pi keybinding without an explicit runtime prompt., The installer adds package paths to Pi's extension settings during installation., An optional browser bridge has broad Chrome permissions and all-site access if a user manually loads it. - **Evidence against:** The package documents the companion registration as part of its Pi integration., The browser bridge is optional and its instructions require the user to load it manually., The browser bridge connects only to a local loopback service., No credential harvesting, external exfiltration, remote payload download, or destructive behavior was found in the inspected lifecycle scripts. ## Affected versions and remediation This report applies to pi-maestro-flow@0.24.0. - Review the evidence and your use of pi-maestro-flow@0.24.0 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.
