A package silently takes control of a broad, persistent AI-agent instruction surface. - **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:** 0.1.8 - **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. Installing the package replaces the user's global Pi agent instructions with package-controlled content. This affects future agent behavior outside the installed project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-06T05:16:49.322Z - **Finished:** 2026-09-06T05:17:29.589Z - **Download time:** 508 ms - **Static scan time:** 81 ms - **AI review time:** 39678 ms - **Total time:** 40267 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:** Installing the package replaces the user's global Pi agent instructions with package-controlled content. This affects future agent behavior outside the installed project. - **Trigger:** npm postinstall during package installation - **Impact:** A package silently takes control of a broad, persistent AI-agent instruction surface. - **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-09-06T05:17:29.589Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic overwrite of ~/.pi/agent/AGENTS.md - **Attack narrative:** The package declares a postinstall hook that loads its bundled global AGENTS.md, creates ~/.pi/agent if needed, and overwrites ~/.pi/agent/AGENTS.md whenever it differs. This is an automatic persistent mutation of the user's global Pi agent control surface, not an explicit setup command or a package-owned extension registration. - **Rationale:** The install-time overwrite of a foreign global AI-agent instruction file is concrete unconsented control-surface mutation. No exfiltration was found, but the lifecycle behavior meets the publish-block policy. - **Files touched:** global/AGENTS.md, scripts/install-agents.mjs, ~/.pi/agent/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs an install hook., The install hook overwrites the user's global Pi agent instruction file., The replacement content is bundled as a global AGENTS.md file. - **Evidence against:** No network endpoint or credential collection was found., The cache exporter’s file writes and browser launch are explicit command actions. ## Affected versions and remediation This report applies to @maxiaochao/pi-toolkit@0.1.8. - Avoid installing @maxiaochao/pi-toolkit@0.1.8. 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.
