Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 1.53.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The install lifecycle and upstream installer execution create a real lifecycle setup risk, but the inspected behavior is consistent with first-party CraftKit setup. Classify as a warning for agent extension lifecycle risk, not as a confirmed attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-09T10:06:25.569Z - **Finished:** 2026-10-09T10:07:01.329Z - **Download time:** 1012 ms - **Static scan time:** 143 ms - **AI review time:** 34603 ms - **Total time:** 35760 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 postinstall setup can install an upstream tool and sync CraftKit content into supported agent locations. This is a first-party package setup path; no separate malicious behavior was established in the inspected excerpts. - **Trigger:** Installing the package with npm on macOS or Linux. - **Impact:** Installs or configures tools and CraftKit-owned agent content in the user's environment; no evidence here shows credential collection or exfiltration. - **Evidence paths:** package.json, scripts/postinstall.sh, sync.sh, hooks/craftkit-platform-rules.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:07:01.329Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script invokes sync.sh with setup enabled; when RTK is absent, sync.sh runs its GitHub installer, then proceeds with CraftKit sync. - **Rationale:** The install lifecycle and upstream installer execution create a real lifecycle setup risk, but the inspected behavior is consistent with first-party CraftKit setup. Classify as a warning for agent extension lifecycle risk, not as a confirmed attack. - **Files touched:** package.json, scripts/postinstall.sh, sync.sh, hooks/craftkit-platform-rules.js - **Network endpoints:** https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall script that starts CraftKit sync automatically., During that setup, if RTK is missing, the script downloads and executes its installer from GitHub., The sync targets supported agent configuration and skill locations, with a migration limited to files containing CraftKit’s legacy managed-block marker., The inspected hook reads platform rules from CraftKit’s own staging directory. - **Evidence against:** The RTK installer runs only when the explicit setup path is active and RTK is absent., The inspected configuration migration checks for CraftKit’s legacy marker before rewriting those files. ## Affected versions and remediation This report applies to @raditia/craftkit@1.53.0. - Review the evidence and your use of @raditia/craftkit@1.53.0 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.
