Unprompted changes to user-level agent behavior and configuration, with an additional remote installer execution when rtk is absent. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.54.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The active postinstall path performs broad user-level agent setup and may execute a remotely fetched installer. This meets the blocking policy for unconsented install-time mutation of AI-agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-09T10:06:32.905Z - **Finished:** 2026-10-09T10:07:04.291Z - **Download time:** 1038 ms - **Static scan time:** 161 ms - **AI review time:** 30184 ms - **Total time:** 31386 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:** Package installation automatically runs setup that installs tooling and synchronizes CraftKit hooks and rules into user-level AI coding tool configuration. - **Trigger:** npm installation invokes the postinstall lifecycle script. - **Impact:** Unprompted changes to user-level agent behavior and configuration, with an additional remote installer execution when rtk is absent. - **Evidence paths:** package.json, scripts/postinstall.sh, sync.sh, adapters/claude.sh, adapters/codex.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:07:04.291Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script enables setup mode, which runs the synchronization path; that path can install an external tool and install or register CraftKit hooks across supported agents. - **Attack narrative:** During npm installation, postinstall enables setup mode and runs the synchronization script. The setup path can install rtk by piping a remote installer into a shell, then installs and registers CraftKit hooks for supported agent tools. This creates an automatic, unconsented change to user-level AI-agent control surfaces. - **Rationale:** The active postinstall path performs broad user-level agent setup and may execute a remotely fetched installer. This meets the blocking policy for unconsented install-time mutation of AI-agent control surfaces. - **Files touched:** $HOME/.claude/hooks, $HOME/.codex - **Network endpoints:** https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package manifest runs a postinstall script that invokes sync.sh with AGENTIC\_SETUP enabled., That setup path installs tooling and runs a remote installer when rtk is missing., The sync process installs hooks and registers them in AI coding tool configuration, including Claude and Codex., These changes happen automatically during package installation and affect user-level agent control surfaces. ## Affected versions and remediation This report applies to @raditia/craftkit@1.54.0. - Avoid installing @raditia/craftkit@1.54.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
