It installs bundled skills/agents across multiple home-directory agent platforms and changes Claude settings. - **Trigger:** npm installation (postinstall) - **Impact:** Package prompts and output configuration become active in installed AI-agent environments. - **Evidence paths:** package.json, scripts/install-skills.mjs, agents/karpathy-reviewer.md - **Review source:** ai\_review - **Reviewed:** 2026-08-15T11:07:38.629Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** cross-platform AI-agent skill, agent, and settings installation - **Attack narrative:** Installing the package invokes scripts/install-skills.mjs automatically. That script fans out bundled skills to configured AI-agent platforms, copies packaged agent prompts into agent-loader directories, and sets Claude's outputStyle when absent. These are unconsented postinstall writes to broad, foreign AI-agent control surfaces, including Codex, Claude, Cursor, and Trae paths. - **Rationale:** The lifecycle hook performs concrete cross-platform AI-agent configuration and prompt installation at npm install time. This meets the blocking policy regardless of the absence of network exfiltration. - **Files touched:** scripts/install-skills.mjs, skills/\*\*, agents/karpathy-reviewer.md, ~/.claude/skills, ~/.claude/agents, ~/.claude/settings.json, ~/.codex/skills, ~/.codex/agents, ~/.cursor/skills, ~/.cursor/agents, ~/.trae/skills, ~/.trae/agents ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs install-skills.mjs as postinstall., Postinstall targets multiple foreign AI-agent home directories, including ~/.claude, ~/.codex, and ~/.cursor., Install-time entrypoint fans out bundled skills to every configured platform., Bundled agent prompts are copied into agent loader directories., Postinstall sets Claude's outputStyle in ~/.claude/settings.json when unset. - **Evidence against:** No network endpoint, credential exfiltration, or remote payload retrieval was found in the inspected lifecycle source., The installer includes opt-out environment variables and avoids replacing unmarked user files. ## Public findings ### 1.
