This occurs without an explicit user setup command. - **Trigger:** npm install - **Impact:** A package install can alter Codex, Claude, OpenCode, and Antigravity agent behavior and available commands. - **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 - **Review source:** ai\_review - **Reviewed:** 2026-08-19T21:01:23.889Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall mutation of global AI-agent configuration and skill/plugin directories - **Attack narrative:** Installing the package automatically executes its postinstall driver. That driver launches deployers which write package-controlled prompts and skills into Codex and Claude directories, merge an OpenCode global configuration containing a command/MCP entry, and install an Antigravity plugin. The installed skill directs host agents to advance the workflow and dispatch subagents. This is unconsented install-time mutation of several foreign, user-global AI-agent control surfaces. - **Rationale:** The source confirms a concrete npm postinstall chain that writes and merges package-controlled content into broad external AI-agent control surfaces. This meets the blocking policy regardless of the absence of observed network exfiltration. - **Files touched:** scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, ~/.codex/skills/audit-code/SKILL.md, ~/.claude/commands/audit-code.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code/plugin.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm lifecycle runs postinstall., Postinstall launches both host-asset deployers., Install-time code writes Claude and Codex skill assets under the user home directory., It also merges global OpenCode configuration and installs a Gemini/Antigravity plugin., Installed audit skill instructs host agents to automatically advance and delegate work. - **Evidence against:** No credential harvesting, payload download, or exfiltration was found in inspected lifecycle sources., The deployed assets are package-branded, but installation is automatic and mutates several foreign agent control surfaces. ## Public findings ### 1.
