It installs package-supplied commands and skills without an explicit setup command. - **Trigger:** npm postinstall - **Impact:** A package install can overwrite or add agent instructions that expose administrative capabilities in later agent sessions. - **Evidence paths:** package.json, scripts/install.js, .codex/skills/account/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:40:46.274Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive copying into global AI-agent command and skill directories - **Attack narrative:** Installing the package automatically runs scripts/install.js. That script creates and populates global Claude command and skill directories, then recursively installs all bundled Codex skills under the user's configured Codex home. The installed account skill instructs an agent to use an administrative user-management API and obtain credentials. This is an unconsented postinstall write to broad AI-agent control surfaces, so later agent behavior can be changed by package content. - **Rationale:** The automatic postinstall broadens a package installation into persistent global AI-agent configuration mutation. The installed content includes instructions for privileged account actions. - **Files touched:** scripts/install.js, .claude/commands, .claude/skills, $CODEX\_HOME/skills/optima-dev, .codex/skills/account/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs its installer automatically after npm installation., The installer recursively copies package commands and skills into the user's global Claude and Codex control directories., An installed Codex skill directs an agent to perform account ban and unban operations with admin credentials. - **Evidence against:** The install script contains no network request or shell command., The manifest has no runtime dependency on another release of this package. ## Public findings ### 1.
