Agent behavior and global configuration can change without a separate setup command; the setup can also fetch and run a remote installer when RTK is missing. - **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:** 1.51.0 - **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 chain performs broad agent setup and registers hooks in global configuration without a separate user command. This supports blocking the package for install-time agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T10:06:10.739Z - **Finished:** 2026-10-09T10:06:51.977Z - **Download time:** 1284 ms - **Static scan time:** 136 ms - **AI review time:** 39815 ms - **Total time:** 41238 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 automatic install hook runs a multi-platform agent setup that modifies global agent directories and configuration. - **Trigger:** Installing the package through npm invokes its postinstall hook. - **Impact:** Agent behavior and global configuration can change without a separate setup command; the setup can also fetch and run a remote installer when RTK is missing. - **Evidence paths:** package.json, scripts/postinstall.sh, sync.sh, adapters/claude.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:06:51.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook enables setup, synchronizes CraftKit rules, skills, commands, and agents across configured adapters, and installs and registers Claude hooks. - **Attack narrative:** During npm installation, the postinstall hook starts the sync script with setup enabled. The script synchronizes package content across configured agent adapters, while the Claude adapter copies hooks into the global hooks directory and registers them. If RTK is absent, setup fetches and runs its remote installer. This is an unconsented install-time change to agent control surfaces. - **Rationale:** The active postinstall chain performs broad agent setup and registers hooks in global configuration without a separate user command. This supports blocking the package for install-time agent control-surface mutation. - **Files touched:** scripts/postinstall.sh, sync.sh, adapters/claude.sh - **Network endpoints:** https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook runs the package sync script with setup enabled, without a separate user command., The setup path downloads and runs an installer when RTK is absent, and the sync runs rule, skill, command, and agent setup for each configured adapter., The Claude adapter copies package hooks into the user's global Claude hooks directory and wires them into settings. ## Affected versions and remediation This report applies to @raditia/craftkit@1.51.0. - Avoid installing @raditia/craftkit@1.51.0. 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.
