A dependency installation can replace instructions applied to Pi agent sessions without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. The automatic postinstall hook mutates the user's global Pi agent control surface. It replaces global instructions when they differ and creates or changes related user-wide files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T04:41:40.435Z - **Finished:** 2026-09-11T04:42:31.902Z - **Download time:** 762 ms - **Static scan time:** 252 ms - **AI review time:** 50452 ms - **Total time:** 51467 ms The recorded confidence comes from the underlying analysis.

It replaces global instructions when they differ and creates or changes related user-wide files. - **Trigger:** npm installation - **Impact:** A dependency installation can replace instructions applied to Pi agent sessions without an explicit setup command. - **Evidence paths:** package.json, scripts/install-agents.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:42:31.902Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall overwrite of global agent configuration and user-wide command installation. - **Attack narrative:** Installing the package invokes its postinstall hook. The hook reads its bundled global instruction file and overwrites the user's global Pi AGENTS.md whenever it differs, so it controls a broad agent instruction surface without an explicit user command. It also creates or modifies Pi settings and copies an executable and shell completion into user-wide locations. - **Rationale:** The package has a concrete automatic lifecycle path that overwrites a foreign, broad AI-agent control surface. Although no exfiltration was found, this satisfies the install-time agent-control mutation blocking policy. - **Files touched:** global/AGENTS.md, ~/.pi/agent/AGENTS.md, ~/.pi/agent/settings.json, bin/pi-worktree, ~/.local/bin/pi-worktree, bin/pi-worktree-completion.bash, ~/.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 policy risk:** Installation automatically runs a package script., That script overwrites the global Pi agent instruction file when its contents differ., It also changes global Pi settings and installs an executable in the user-wide local bin directory. - **Evidence against:** The install script contains no network request or credential collection., The flagged browser code uses local debugging endpoints for explicit browser tooling and tests. ## Affected versions and remediation This report applies to @maxiaochao/pi-toolkit@0.3.0. - Avoid installing @maxiaochao/pi-toolkit@0.3.0. 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.
