A package install changes a foreign AI-agent runtime and broad user command-discovery surface without an explicit setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.86 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically installs a separate global Claude Code CLI if absent and persists global-command PATH changes. It also creates launchers for a provisioned app. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-23T01:05:16.817Z - **Finished:** 2026-08-23T01:06:31.406Z - **Download time:** 512 ms - **Static scan time:** 124 ms - **AI review time:** 73952 ms - **Total time:** 74589 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically installs a separate global Claude Code CLI if absent and persists global-command PATH changes. It also creates launchers for a provisioned app. - **Trigger:** npm install, via postinstall - **Impact:** A package install changes a foreign AI-agent runtime and broad user command-discovery surface without an explicit setup command. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T01:06:31.406Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented global AI CLI installation plus persistent user-environment mutation - **Attack narrative:** On npm installation, the lifecycle hook provisions a bundled Python application, then installs @anthropic-ai/claude-code globally when it is missing. The same hook persists the npm global bin directory in user shell startup files or the Windows user PATH and creates launchers. These effects occur without a separate user setup command and extend beyond the package-owned environment into a foreign AI-agent CLI and broad command-resolution surface. - **Rationale:** The source establishes an unconsented postinstall chain that installs a foreign AI-agent CLI globally and persists user-environment changes. This meets the blocking boundary for install-time mutation of a foreign/broad AI-agent control surface. - **Files touched:** ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc, HKCU\\Environment\\Path, ~/Desktop/Takkub Cockpit.app, ~/Applications/Takkub Cockpit.app ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm installation., Postinstall globally installs @anthropic-ai/claude-code when absent., Postinstall persists the npm global bin directory in shell startup files or the Windows user PATH., Postinstall creates desktop/application launchers that execute its provisioned Python app. - **Evidence against:** The installer provisions its Python environment under ~/.agent-takkub rather than a project venv., No explicit remote URL, credential exfiltration, or payload download appears in the inspected npm lifecycle source. ## Public findings ### 1.
