Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Automatic installation makes persistent user-profile changes and may install a separate global AI-agent CLI. No confirmed credential theft, remote payload execution, or AI-agent configuration takeover was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-29T08:16:53.342Z - **Finished:** 2026-09-29T08:18:37.965Z - **Download time:** 520 ms - **Static scan time:** 106 ms - **AI review time:** 103996 ms - **Total time:** 104623 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:** Automatic installation makes persistent user-profile changes and may install a separate global AI-agent CLI. No confirmed credential theft, remote payload execution, or AI-agent configuration takeover was identified. - **Trigger:** npm post-install execution. - **Impact:** A package installation can alter persistent command resolution and add executables or launchers without a separate user command. - **Evidence paths:** npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T08:18:37.965Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer provisions a Python environment, can invoke a global npm install, appends shell PATH settings, and creates a user application launcher. - **Rationale:** The automatic lifecycle hook has meaningful persistent side effects beyond installing this package, including a conditional global third-party CLI installation. This warrants a warning, but the inspected evidence does not support a malicious block verdict. - **Files touched:** npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares an automatic post-install script., The post-install script installs the Anthropic CLI globally when absent., The same automatic path persists an npm bin directory in shell startup files., It also creates a desktop application launcher in the user profile. - **Evidence against:** No self-dependency is declared in the inspected package manifest., No credential export or unrelated network destination was identified in the inspected npm launcher code. ## Affected versions and remediation This report applies to agent-takkub@2.1.46. - Review the evidence and your use of agent-takkub@2.1.46 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.
