A package installation can alter foreign AI-agent control surfaces and bypass a configured WorkBuddy safety preload without a separate user 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:** 0.1.18 - **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. A global-install postinstall hook automatically installs an AI skill into external assistant configuration directories. It also removes a WorkBuddy safety preload for the child installation process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-29T14:35:47.221Z - **Finished:** 2026-09-29T14:38:40.443Z - **Download time:** 514 ms - **Static scan time:** 68 ms - **AI review time:** 172639 ms - **Total time:** 173222 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:** A global-install postinstall hook automatically installs an AI skill into external assistant configuration directories. It also removes a WorkBuddy safety preload for the child installation process. - **Trigger:** Installing this package globally without the opt-out environment variable. - **Impact:** A package installation can alter foreign AI-agent control surfaces and bypass a configured WorkBuddy safety preload without a separate user command. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js, bin/install-env.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T14:38:40.443Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook runs the launcher, which invokes a noninteractive skills installer and copies the bundled skill to CodeBuddy and WorkBuddy configuration paths. - **Attack narrative:** On global installation, the lifecycle hook automatically starts a skill installer. The launcher uses a noninteractive skills command, copies package content into CodeBuddy and WorkBuddy home configuration directories, and strips a WorkBuddy safe-delete preload from the child environment. This is an unconsented lifecycle mutation of foreign AI-agent control surfaces. - **Rationale:** The automatic global postinstall path modifies external agent configuration and disables a named safety preload for its child process. Those concrete behaviors meet the install-control-surface blocking boundary. - **Files touched:** .codebuddy/skills/guanmetric, .workbuddy/skills/guanmetric ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., The hook launches install-skill during global installs., The command noninteractively invokes the skills CLI to install this package globally., The launcher copies the skill into CodeBuddy and WorkBuddy home configuration directories., The installation child environment removes a WorkBuddy safe-delete preload from NODE\_OPTIONS. - **Evidence against:** The postinstall hook skips local installs, CI, and an explicit opt-out setting. ## Affected versions and remediation This report applies to @guandata/guanmetric@0.1.18. - Avoid installing @guandata/guanmetric@0.1.18. 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.
