It can add or overwrite Claude Code skills in the global user profile or consuming project, changing the agent instructions and executable workflow payload available to Claude Code. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.8.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook modifies Claude Code skill directories without a separate user command. A global install targets the shared Claude skills directory and can replace matching skill files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 95.0% - **Started:** 2026-09-03T18:04:09.512Z - **Finished:** 2026-09-03T18:04:49.298Z - **Download time:** 770 ms - **Static scan time:** 266 ms - **AI review time:** 38749 ms - **Total time:** 39786 ms ## Security analysis ### Published attack-surface review - **Summary:** The npm postinstall hook modifies Claude Code skill directories without a separate user command. A global install targets the shared Claude skills directory and can replace matching skill files. - **Trigger:** Installing the package with npm, especially npm install -g. - **Impact:** It can add or overwrite Claude Code skills in the global user profile or consuming project, changing the agent instructions and executable workflow payload available to Claude Code. - **Evidence paths:** package.json, bin/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T18:04:49.298Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies bundled skills into Claude Code control directories and imports copied workflow modules. - **Attack narrative:** npm invokes bin/install.js automatically after installation. The script selects either ~/.claude/skills for global installs or the consuming project's .claude/skills directory, then recursively copies its bundled skills, workflows, and guidance there. Matching destination files are overwritten. It subsequently dynamically imports copied workflow modules, so package-controlled code is executed during the lifecycle hook. This changes a broad AI-agent control surface without a separate setup command. - **Rationale:** This is an automatic postinstall mutation of Claude Code's global or project skill control surface, including overwriting matching skills and executing copied modules. The lack of network or credential theft does not neutralize the install-hook control-surface hijack. - **Files touched:** ~/.claude/skills/, \/.claude/skills/, \/.gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package automatically runs its installer during npm postinstall., On global installs, it writes into Claude Code's shared ~/.claude/skills directory., On local installs, it copies bundled skills and workflows into the consuming project's .claude/skills directory, overwriting matching files., The install hook dynamically imports every copied workflow module as a smoke check. - **Evidence against:** No network, credential harvesting, shell execution, or self-dependency was found in the installer., The installer limits its source inputs to bundled skill, workflow, and guidance files. ## Public findings ### 1.
