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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T10:10:16.148Z - **Finished:** 2026-09-13T10:11:11.543Z - **Download time:** 771 ms - **Static scan time:** 188 ms - **AI review time:** 54436 ms - **Total time:** 55395 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:** Installing the package automatically changes detected AI-agent configuration. For Claude Code it installs a machine-global SessionStart command hook that runs the package validator in future sessions. - **Trigger:** npm postinstall when Claude Code is detected and Python is available. - **Impact:** It persistently alters a broad foreign AI-agent control surface and causes package code to run in later agent sessions. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T10:11:11.543Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic user-level AI-agent hook installation. - **Rationale:** The package has a concrete automatic postinstall path that writes a command hook into Claude's user-level settings. This meets the install-control-surface blocking policy even though no exfiltration was found. Product guard normalized uninstall-only AI-agent control-surface mutation to warn-only suspicious because modern npm does not run uninstall lifecycle scripts and the install path is user-invoked. - **Files touched:** scripts/postinstall.js, scripts/lib.js, ~/.claude/skills/kb-agentic-skill, ~/.claude/settings.json, ~/.agentic-sdlc/orient-hook-wired ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall detects AI clients and invokes global hook wiring without a user prompt., The global wiring appends a command-bearing SessionStart hook to the Claude user settings file., The manifest activates this behavior through npm postinstall. - **Evidence against:** No network client, credential collection, or exfiltration endpoint was found in the inspected source., The uninstall script removes hooks attributable to this package, but that does not make the automatic install-time mutation consensual. ## Affected versions and remediation This report applies to @antoneeo/kb-agentic-skill@1.14.0. - Review the evidence and your use of @antoneeo/kb-agentic-skill@1.14.0 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.
