It also installs workflow resources under the user's Maestro home. - **Trigger:** npm installation, through postinstall. - **Impact:** A package install alters the agent's keybindings and active package list without an explicit setup command. - **Evidence paths:** package.json, scripts/configure-keybindings.mjs, scripts/register-companion-packages.mjs, scripts/install-workflows.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T20:40:20.849Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of global AI-agent configuration and extension registration. - **Attack narrative:** On npm installation, the package automatically runs scripts that modify the user's global Pi-agent keybindings and settings. The settings mutation registers dependency directories as Pi packages, enabling their extensions in the agent control surface. A separate lifecycle script invokes a dependency CLI or copies workflow resources into the global Maestro directory. These are unconsented install-time changes outside the installed package. - **Rationale:** The package has a concrete automatic postinstall path that mutates global AI-agent configuration and activates companion extensions. This meets the install-hook abuse boundary even though the inspected code did not show exfiltration. - **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:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Its automatic postinstall runs three configuration scripts., The lifecycle script writes a global Pi agent keybindings file., It adds companion package paths to the global Pi agent settings file., It runs a dependency CLI and can copy workflow resources into the user's Maestro home. - **Evidence against:** No runtime dependency on pi-maestro-flow itself is declared., The inspected lifecycle scripts show no credential collection or network exfiltration. ## Affected versions and remediation This report applies to pi-maestro-flow@0.29.0. - Avoid installing pi-maestro-flow@0.29.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
