It adds instruction cards, skills, and command hooks, then repairs them whenever the CLI runs. - **Trigger:** Installing the package globally, or later running any CLI command other than uninstall. - **Impact:** The package can influence agent behavior and register commands in the user's Claude or Codex environment without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install/global.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:11:39.373Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic persistent mutation of AI-agent control surfaces and hook configuration. - **Attack narrative:** The postinstall hook runs during a global npm install and invokes setupGlobal. That setup writes agent instruction cards and skills and adds PreToolUse and PostToolUse command hooks to Claude and Codex user-home configuration. The CLI then automatically restores missing or stale copies on subsequent commands. This is an unconsented lifecycle mutation of broad, foreign AI-agent control surfaces. - **Rationale:** This package has a concrete automatic postinstall path that persistently modifies user-level AI-agent configuration and hooks. The global-install guard does not provide explicit user consent for that control-surface mutation. - **Files touched:** ~/.claude/CLAUDE.md, ~/.claude/skills, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills, ~/.codex/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script., On global installation, that script automatically calls global setup., Global setup writes cards and skills and installs command hooks into Claude and Codex home control surfaces., Every normal CLI command repairs missing or stale global surfaces, making the mutation persistent. - **Evidence against:** The postinstall script limits its automatic path to global installs., The inspected GitHub client uses an explicit API endpoint for user-invoked research; no secret exfiltration was found in the lifecycle path. ## Public findings ### 1.
