Package-controlled instructions become available to the user's AI-agent environments and can overwrite same-named installed files. - **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:** 0.16.11 - **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. An npm postinstall hook changes global Claude and Codex agent control surfaces without a separate user command. No network exfiltration was identified in the installer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-22T02:50:18.871Z - **Finished:** 2026-09-22T02:51:15.453Z - **Download time:** 1016 ms - **Static scan time:** 966 ms - **AI review time:** 54599 ms - **Total time:** 56582 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:** An npm postinstall hook changes global Claude and Codex agent control surfaces without a separate user command. No network exfiltration was identified in the installer. - **Trigger:** Installing the npm package runs postinstall automatically. - **Impact:** Package-controlled instructions become available to the user's AI-agent environments and can overwrite same-named installed files. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T02:51:15.453Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install script creates global agent directories and copies all packaged Claude commands and skills plus Codex skills into them. - **Attack narrative:** A normal npm installation invokes scripts/install.js. That script writes package-provided command and skill content into the user's global Claude directories and package-provided skills into the Codex skills directory. This is an unconsented install-time mutation of broad AI-agent control surfaces, so the package can alter future agent behavior independently of the project where it was installed. - **Rationale:** The automatic postinstall hook performs broad global AI-agent configuration writes. This meets the install-control-surface blocking condition even though the installer itself contains no observed network send. - **Files touched:** ~/.claude/commands, ~/.claude/skills, $CODEX\_HOME/skills/optima-dev ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs scripts/install.js through an npm postinstall hook., The installer targets the user's global Claude and Codex agent configuration directories., The postinstall hook copies every packaged Claude command and skill into the global Claude control surface., The same hook recursively copies packaged Codex skills into the user's Codex skills directory. - **Evidence against:** The installer source inspected here does not itself send data to a network endpoint. ## Affected versions and remediation This report applies to @optima-chat/dev-skills@0.16.11. - Avoid installing @optima-chat/dev-skills@0.16.11. 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.
