It also creates application launchers before the user invokes this package. - **Trigger:** npm install (postinstall) - **Impact:** Adds a foreign AI-agent control surface and shell persistence outside the package-owned venv. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.72-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-17T03:14:07.853Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented global AI CLI installation and persistent environment mutation - **Attack narrative:** Installing the npm package runs postinstall. If Claude is absent, it invokes npm to globally install @anthropic-ai/claude-code, then persists the npm global bin directory in user shell settings and creates launchers. These changes occur without an explicit follow-up command or consent for a foreign AI-agent CLI. - **Rationale:** The package performs unconsented postinstall installation of a third-party AI-agent CLI and persistent user-environment changes. This meets the install-time foreign AI-agent control-surface mutation block boundary. - **Files touched:** ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc, ~/Desktop/Takkub Cockpit.app, ~/Applications/Takkub Cockpit.app ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm install., It globally installs the foreign @anthropic-ai/claude-code CLI when absent., It alters persistent user PATH settings during postinstall., It creates desktop/application launchers during postinstall. - **Evidence against:** No direct credential harvesting or exfiltration was found in inspected npm wrapper sources., The bundled wheel is installed from the package archive into a dedicated venv. ## Public findings ### 1.
