These changes occur before the user invokes either CLI. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** It can add package-authored agent capabilities and permissions to Codex, Claude, OpenCode, and Antigravity environments without explicit operator action. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:29:36.981Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic deployment and overwrite of global AI-agent assets and configuration. - **Attack narrative:** An npm postinstall launches package deployers automatically. The audit deployer installs package-controlled prompts and skills into global Codex and Claude paths, modifies the global OpenCode configuration with an agent command and permissions, and writes an external Claude plugin. The common writer creates directories and overwrites existing files. This is an unconsented install-time mutation of multiple AI-agent control surfaces. - **Rationale:** The package performs automatic, cross-platform global AI-agent control-surface writes during npm installation. This concrete lifecycle behavior meets the blocking policy regardless of the absence of observed network exfiltration. - **Files touched:** ~/.codex/skills/audit-code/SKILL.md, ~/.codex/skills/audit-code/audit-code.prompt.md, ~/.claude/commands/audit-code.md, ~/.config/opencode/opencode.json, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code/.claude-plugin/plugin.json, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code/commands/audit-code.md, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code/skills/audit-code/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script on installation., The postinstall launches both host-asset deployers and also changes the consuming repository's .gitignore., The audit deployer writes package-controlled skills and prompts into global Codex and Claude directories without an explicit user command., It also merges an agent command and permission rules into the global OpenCode configuration and installs a Claude external plugin., The shared writer creates parent directories and overwrites target files. - **Evidence against:** No network request or credential collection was found in the inspected install-time files., The package has no runtime dependency on its own name. ## Public findings ### 1.
