It installs skills, prompts, commands, and plugins without an explicit user command. - **Trigger:** npm install / postinstall - **Impact:** Adds package-controlled commands and skills to Codex, OpenCode, Claude, and Antigravity environments. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, skills/audit-code/SKILL.md, skills/remediate-code/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-19T07:23:23.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic global AI-agent skill and configuration deployment - **Attack narrative:** On npm installation, package.json invokes scripts/postinstall.mjs, which launches both deployers. They copy package-controlled skills and prompts into global Codex and Claude locations, merge a global OpenCode command/agent configuration, and install Antigravity and Claude plugins. These changes activate automatically for future AI-agent sessions and occur without a user selecting the package commands or consenting to agent-control configuration changes. - **Rationale:** The lifecycle hook concretely mutates multiple foreign, broad AI-agent control surfaces at install time. This satisfies the blocking policy even though no separate exfiltration endpoint was found. - **Files touched:** ~/.codex/skills/audit-code/SKILL.md, ~/.codex/skills/audit-code/audit-code.prompt.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code/plugin.json, ~/.claude/commands/audit-code.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall executes host-asset deployers automatically., Install-time code writes global Codex skills and prompts under the user home directory., It merges a global OpenCode configuration and installs global Antigravity and Claude plugins., The installed skills direct AI hosts to run package commands and persist workflow artifacts. - **Evidence against:** No credential harvesting or network-exfiltration code was identified in inspected lifecycle sources., Postinstall writes package-branded assets and includes restrictive OpenCode command rules, but this does not make the unconsented global mutation safe. ## Public findings ### 1.
