It overwrites global agent instructions and also places a user-wide executable. - **Trigger:** Installing the package runs its postinstall lifecycle hook. - **Impact:** The package can replace instructions used by the user's Pi agent and persist a command in the user's home directory. - **Evidence paths:** package.json, scripts/install-agents.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T06:05:40.885Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes global Pi configuration and copies user-wide files. - **Attack narrative:** On installation, npm invokes scripts/install-agents.mjs. The hook compares the existing global .pi/agent/AGENTS.md with its bundled content and overwrites it whenever it differs, rather than obtaining consent or limiting changes to this package's own directory. It also initializes global Pi settings and copies a command into .local. This is unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The postinstall hook automatically overwrites global Pi agent instructions and creates user-wide files. This meets the install-hook abuse policy even though no network exfiltration was found. - **Files touched:** package.json, scripts/install-agents.mjs, .pi/agent/AGENTS.md, .pi/agent/settings.json, .local/bin/pi-worktree, .local/share/bash-completion/completions/pi-worktree ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs an installer after npm installation., That installer overwrites the user's global Pi agent instructions when they differ and creates or changes global agent settings., The same automatic hook copies an executable and shell completion into user-wide locations. - **Evidence against:** The automatic installer contains no network request or secret-harvesting code., There is no runtime dependency on another release of this package. ## Affected versions and remediation This report applies to @maxiaochao/pi-toolkit@0.5.0. - Avoid installing @maxiaochao/pi-toolkit@0.5.0. 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.
