Persists package-supplied behavior across the user's Pi agent environment and replaces existing global instructions. - **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:** 0.2.6 - **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. During npm installation, the package overwrites the global Pi agent instruction file whenever it differs from its bundled content. It also initializes global Pi agent settings without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-09T10:31:33.130Z - **Finished:** 2026-09-09T10:32:39.451Z - **Download time:** 508 ms - **Static scan time:** 230 ms - **AI review time:** 65582 ms - **Total time:** 66321 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:** During npm installation, the package overwrites the global Pi agent instruction file whenever it differs from its bundled content. It also initializes global Pi agent settings without an explicit user command. - **Trigger:** npm postinstall - **Impact:** Persists package-supplied behavior across the user's Pi agent environment and replaces existing global instructions. - **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-09-09T10:32:39.451Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall mutation of global Pi agent instructions and settings. - **Attack narrative:** Installing the package runs its postinstall hook automatically. That hook reads the package's bundled AGENTS.md and replaces the user's global ~/.pi/agent/AGENTS.md whenever the contents differ, then creates or changes ~/.pi/agent/settings.json. This is an unconsented mutation of a broad AI-agent control surface, not package-local setup. The inspected installer does not exfiltrate data or contact a network endpoint. - **Rationale:** The automatic postinstall replaces global Pi agent instructions rather than setting up package-local artifacts, constituting unconsented broad AI-agent control-surface mutation. No credential exfiltration was found, but the lifecycle behavior meets the publish-block policy. - **Files touched:** scripts/install-agents.mjs, global/AGENTS.md, ~/.pi/agent/AGENTS.md, ~/.pi/agent/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs an installer after npm installation., The installer overwrites the global Pi agent instruction file whenever it differs from the bundled content., The installer creates or changes global Pi agent settings without an explicit user command., The bundled file contains behavioral instructions intended for an agent. - **Evidence against:** The installer source has no network, credential-harvesting, or subprocess behavior., The inspected local network code is browser-test tooling that uses a loopback endpoint. ## Affected versions and remediation This report applies to @maxiaochao/pi-toolkit@0.2.6. - Avoid installing @maxiaochao/pi-toolkit@0.2.6. 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.
