Changes instructions across Pi sessions and discards any differing 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:** 0.1.7 - **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. Installation replaces Pi's global agent instruction file with package-supplied instructions. Existing user instructions are overwritten without a consent check. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T20:14:23.512Z - **Finished:** 2026-09-30T20:15:05.966Z - **Download time:** 1037 ms - **Static scan time:** 59 ms - **AI review time:** 41358 ms - **Total time:** 42454 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:** Installation replaces Pi's global agent instruction file with package-supplied instructions. Existing user instructions are overwritten without a consent check. - **Trigger:** npm postinstall execution. - **Impact:** Changes instructions across Pi sessions and discards any differing existing global instructions. - **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-09-30T20:15:05.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook reads bundled global/AGENTS.md and writes it to the user's global Pi agent context whenever missing or different. - **Attack narrative:** Installing the package automatically runs a hook that copies bundled behavioral instructions into Pi's global agent context. The hook replaces differing existing contents without prompting or preserving them. This is a broad agent control surface rather than a package-owned extension configuration. - **Rationale:** Source proves unconsented postinstall mutation of a broad AI-agent control surface. The supplied policy requires blocking this behavior even though the bundled instructions appear ordinary. - **Files touched:** ~/.pi/agent/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs scripts/install-agents.mjs after installation., scripts/install-agents.mjs creates or overwrites ~/.pi/agent/AGENTS.md with bundled instructions whenever its contents differ, without consent or backup., global/AGENTS.md supplies coding behavior instructions for the global agent context. - **Evidence against:** The bundled instructions concern ordinary coding practices; no credential theft was established., The cache export entrypoint writes session dashboards through an explicitly invoked command. ## Affected versions and remediation This report applies to @maxiaochao/pi-toolkit@0.1.7. - Avoid installing @maxiaochao/pi-toolkit@0.1.7. 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.
