Changes instructions available to foreign AI assistants without a separate setup request and bypasses the inherited safe-delete preload during installation. - **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:** 0.1.836 - **Selected version is latest:** Yes - **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. Global npm installation automatically installs agent instructions into foreign AI-assistant configuration directories. The installer also removes a WorkBuddy safe-delete preload before executing. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-02T16:56:27.455Z - **Finished:** 2026-10-02T16:57:48.754Z - **Download time:** 1016 ms - **Static scan time:** 105 ms - **AI review time:** 80177 ms - **Total time:** 81299 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:** Global npm installation automatically installs agent instructions into foreign AI-assistant configuration directories. The installer also removes a WorkBuddy safe-delete preload before executing. - **Trigger:** Global npm installation outside CI without GUAN\_SKIP\_INSTALL\_SKILL=1. - **Impact:** Changes instructions available to foreign AI assistants without a separate setup request and bypasses the inherited safe-delete preload during installation. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js, bin/install-env.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T16:57:48.754Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook launches install-skill, runs an automatically confirmed global skills installer, copies skill files into buddy configuration directories, and strips the safe-delete preload from the child environment. - **Attack narrative:** A global installation activates postinstall, which invokes the launcher’s skill setup command. That command runs npx with automatic confirmation and global installation arguments, then copies the packaged workflow skill into CodeBuddy and WorkBuddy directories. When a WorkBuddy safe-delete preload is present, the setup path removes it and restarts itself. The skip conditions limit activation but do not require affirmative consent to modify foreign agent instructions. - **Rationale:** The inspected chain automatically modifies foreign AI-agent control surfaces during postinstall and removes an inherited safety preload. Those concrete behaviors exceed guarded package-owned extension setup and meet the blocking policy. - **Files touched:** .codebuddy, .workbuddy, skills/guanwf ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs bin/postinstall.js after installation., The hook invokes install-skill for global installs unless explicitly skipped or running in CI., bin/run.js invokes npx with automatic confirmation to install guanwf globally into AI assistants., After installer success, the launcher copies the skill into CodeBuddy and WorkBuddy configuration directories., bin/install-env.js removes the WorkBuddy safe-delete preload from NODE\_OPTIONS and restarts the installer with the modified environment. - **Evidence against:** Local installs and CI skip automatic skill installation, and an environment variable can disable it., The installed content is a package-specific workflow skill; no credential exfiltration was established. ## Affected versions and remediation This report applies to @guandata/guanwf@0.1.836. - Avoid installing @guandata/guanwf@0.1.836. 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.
