The package can establish persistent instructions affecting future AI-agent activity without an explicit setup 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:** 0.1.0 - **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. Installation automatically creates a global AI-agent instruction file if one is absent. The file supplies behavior rules for all agents and scenarios. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T07:42:04.471Z - **Finished:** 2026-09-12T07:42:42.127Z - **Download time:** 520 ms - **Static scan time:** 57 ms - **AI review time:** 37077 ms - **Total time:** 37656 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 automatically creates a global AI-agent instruction file if one is absent. The file supplies behavior rules for all agents and scenarios. - **Trigger:** npm postinstall during package installation. - **Impact:** The package can establish persistent instructions affecting future AI-agent activity without an explicit setup command. - **Evidence paths:** package.json, bin/gsm.mjs, bin/config.mjs, defaults/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-09-12T07:42:42.127Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic creation of a global agent instruction file. - **Attack narrative:** Installing the package runs its postinstall hook. The hook calls the backup command, which initializes the global ~/.agents directory and copies the package's AGENTS.md if absent. That bundled file declares rules for all agents across all scenarios, creating a persistent broad agent-control surface without an explicit user setup action. - **Rationale:** This is an unconsented postinstall mutation of a broad global AI-agent control surface. Exclusive creation avoids overwrites but does not remove the risk of first-install persistence. - **Files touched:** ~/.agents/AGENTS.md, ~/.agents/skills.json, ~/.gsm/backups ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically runs the manager's backup command., That command unconditionally initializes configuration under the user's global agent directory., Initialization copies this package's bundled AGENTS.md into the global agent control surface when absent., The bundled file says its instructions apply to all agents across all scenarios. - **Evidence against:** The automatic path does not invoke the npx downloader; that occurs only during later skill-install commands., The AGENTS.md copy uses exclusive creation and does not overwrite an existing file. ## Affected versions and remediation This report applies to global-skills-manager@0.1.0. - Avoid installing global-skills-manager@0.1.0. 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.
