A package install changes Claude, Codex, OpenCode, and Antigravity behavior without a separate user setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.50.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically deploys global AI-agent commands, skills, plugin files, and OpenCode configuration. These writes affect several host applications outside the installed project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-28T04:13:21.413Z - **Finished:** 2026-08-28T04:14:19.534Z - **Download time:** 511 ms - **Static scan time:** 3539 ms - **AI review time:** 54070 ms - **Total time:** 58121 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically deploys global AI-agent commands, skills, plugin files, and OpenCode configuration. These writes affect several host applications outside the installed project. - **Trigger:** npm postinstall during package installation - **Impact:** A package install changes Claude, Codex, OpenCode, and Antigravity behavior without a separate user setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:14:19.534Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent control-surface mutation - **Attack narrative:** On installation, the postinstall entrypoint launches both deployers. They write package-provided prompts and skills into global Claude and Codex directories, merge global OpenCode commands and agent permissions, and add Antigravity plugins. The write helper creates directories and replaces prior generated files. This is unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The package performs confirmed postinstall writes to multiple global AI-agent configuration locations. This meets the blocking policy regardless of the absence of confirmed credential exfiltration. - **Files touched:** ~/.claude/commands/audit-code.md, ~/.claude/commands/remediate-code.md, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code, ~/.codex/skills/audit-code, ~/.codex/skills/remediate-code, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code, ~/.gemini/config/plugins/remediate-code ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook runs both host-asset deployers automatically., The audit deployer writes global Claude and Codex command and skill files., The deployer merges a global OpenCode configuration and installs an Antigravity plugin., The shared writer creates parent directories and overwrites existing generated files. - **Evidence against:** No credential harvesting or network exfiltration was confirmed in the inspected lifecycle code., The generated OpenCode permission defaults use confirmation for wildcard edit and shell access. ## Public findings ### 1.
