Install-time changes are package-aligned provisioning, PATH repair, and a desktop shortcut; agent hook wiring occurs only for panes launched by the application. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 88.0% - **Started:** 2026-07-13T04:21:57.414Z - **Finished:** 2026-07-13T04:23:41.458Z - **Download time:** 507 ms - **Static scan time:** 381 ms - **AI review time:** 103155 ms - **Total time:** 104044 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. Install-time changes are package-aligned provisioning, PATH repair, and a desktop shortcut; agent hook wiring occurs only for panes launched by the application. - **Trigger:** npm install -g agent-takkub; later explicit application/CLI use - **Impact:** Installs a bundled Python app and may modify the user's PATH, but no foreign AI-agent control-surface mutation or exfiltration was confirmed. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, dist/agent\_takkub-1.0.24-py3-none-any.whl:agent\_takkub/hook\_wiring.py, dist/agent\_takkub-1.0.24-py3-none-any.whl:agent\_takkub/remote/http\_server.py - **Review source:** ai\_review - **Reviewed:** 2026-07-13T04:23:41.458Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** isolated Python environment provisioning and package-owned Claude-pane hook settings - **Rationale:** The lifecycle hook performs conspicuous but package-aligned provisioning and PATH/shortcut setup, not a concrete malicious chain. Static hints overstate package-owned runtime hook and optional remote features as AI-agent hijacking. - **Files touched:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, npm/scripts/lib.js, npm/scripts/preflight.js, npm/bin/agent-takkub.js, npm/bin/takkub.js, dist/agent\_takkub-1.0.24-py3-none-any.whl ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for:** package.json invokes npm/scripts/postinstall.js on install., npm/scripts/postinstall.js creates an isolated ~/.agent-takkub venv, installs its bundled wheel, may install the Claude CLI, and invokes PATH/shortcut helpers., npm/scripts/pathfix.js persistently adds npm's global bin directory to user shell/registry PATH. - **Evidence against:** postinstall.js does not write ~/.claude plugins, project settings, or other foreign AI-agent control files., The bundled wheel contains readable Python source; no obfuscated loader, eval/exec payload, or credential-exfiltration chain was found in reviewed sources., hook\_wiring.py writes static hook settings only under the package runtime directory and passes them to package-launched Claude panes., Remote code uses loopback HTTP/TCP and optional tunnel functionality; no hidden install-time network endpoint was identified., CLI wrappers only launch the provisioned package module after explicit user invocation. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
