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:** 1.59.0 - **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 automatic postinstall integration registers CraftKit-owned agent hooks, which warrants a warning for agent extension lifecycle risk. The inspected behavior is first-party integration setup, and the source does not establish a concrete attack or justify blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-12T07:22:59.838Z - **Finished:** 2026-10-12T07:23:40.653Z - **Download time:** 1040 ms - **Static scan time:** 216 ms - **AI review time:** 39556 ms - **Total time:** 40815 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:** The install hook automatically syncs CraftKit into supported agent environments and registers package-owned Codex hooks. This is a guarded first-party agent integration setup; the inspected source does not establish a concrete attack. - **Trigger:** Installing the package through npm invokes its postinstall hook. - **Impact:** The integration adds package-owned behavior to later agent sessions and tool events, creating an agent extension lifecycle risk without evidence of malicious control or data theft. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T07:23:40.653Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs sync.sh with agent setup enabled; the Codex adapter copies CraftKit hook scripts and registers them for supported Codex events. - **Rationale:** The automatic postinstall integration registers CraftKit-owned agent hooks, which warrants a warning for agent extension lifecycle risk. The inspected behavior is first-party integration setup, and the source does not establish a concrete attack or justify blocking publication. - **Files touched:** package.json, scripts/postinstall.sh, sync.sh, adapters/codex.sh - **Network endpoints:** https://registry.npmjs.org/@raditia/craftkit/latest ### 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 postinstall runs its sync script with agent setup enabled., The Codex adapter installs CraftKit hooks and registers them for session, prompt, tool, and turn events., The inspected agent-profile check only reads a profile and recognizes CraftKit-managed read-only profiles; this is guarded first-party integration behavior., The update check contacts the package's npm registry endpoint to report a newer version., The cross-review script excludes untracked files, including environment files, from its review input. - **Evidence against:** The inspected sources do not establish credential theft, unrelated data exfiltration, destructive behavior, or remote payload execution., The Codex profile check itself reads a profile file and does not modify it. ## Affected versions and remediation This report applies to @raditia/craftkit@1.59.0. - Review the evidence and your use of @raditia/craftkit@1.59.0 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.
