Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed attack was identified. Inspected installation behavior provisions the application, while reviewed runtime credential requests use the intended service and remote control defaults to disabled. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-30T12:52:57.710Z - **Finished:** 2026-09-30T12:56:21.730Z - **Download time:** 520 ms - **Static scan time:** 102 ms - **AI review time:** 203397 ms - **Total time:** 204020 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed attack was identified. Inspected installation behavior provisions the application, while reviewed runtime credential requests use the intended service and remote control defaults to disabled. - **Trigger:** npm installation runs the bootstrap; explicit CLI or desktop launch starts the application. - **Impact:** Package installation changes application storage and launcher settings; inspected source did not establish credential exfiltration or unconsented install-time mutation of broad agent controls. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T12:56:21.730Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bootstrap installs a bundled Python wheel, optionally installs a missing Claude CLI, and creates command PATH entries and desktop launchers. - **Rationale:** Inspected behavior is consistent with installing and operating an agent orchestration desktop application. Static inspection found no concrete malicious chain, hidden credential destination, or install-time takeover of foreign agent configuration. - **Files touched:** .agent-takkub, .zshrc, .bashrc, Takkub Cockpit.lnk, Takkub Cockpit.app - **Network endpoints:** https://api.anthropic.com/api/oauth/usage, https://console.anthropic.com/v1/oauth/token ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json declares CLI entrypoints and a postinstall bootstrap, with no runtime self-dependency., The install hook installs the bundled wheel into a package-specific Python environment., The wheel contains the inspected Python GUI and CLI runtime; reviewed authentication requests target the intended service., lib.js defaults the environment to the user's .agent-takkub directory., shortcut.js creates launchers for the package's Python module; PATH changes support its installed commands., The CLI wrapper forwards user arguments to the provisioned Python CLI. ## Affected versions and remediation This report applies to agent-takkub@2.1.48. - Review the evidence and your use of agent-takkub@2.1.48 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
