Unconsented mutation of a foreign AI-agent control surface; copied instructions may affect subsequent agent behavior. - **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:** 0.36.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Install-time code can create Claude Code control files outside the dependency directory. Its default-approve prompt permits this without an affirmative response. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-05T22:12:34.923Z - **Finished:** 2026-08-05T22:13:08.718Z - **Download time:** 505 ms - **Static scan time:** 836 ms - **AI review time:** 32451 ms - **Total time:** 33795 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code can create Claude Code control files outside the dependency directory. Its default-approve prompt permits this without an affirmative response. - **Trigger:** npm postinstall - **Impact:** Unconsented mutation of a foreign AI-agent control surface; copied instructions may affect subsequent agent behavior. - **Evidence paths:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T22:13:08.718Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default-approved copy of AI-agent instruction/config files into a parent project root - **Attack narrative:** During npm postinstall, the package checks a node\_modules context, derives a parent project location, prompts with “(Y/n)”, and treats an empty response as approval. It then creates CLAUDE.md and .claude/ there when absent. This is an install-time mutation of an AI-agent control surface outside the package, rather than an explicitly invoked setup action. - **Rationale:** The lifecycle hook performs default-approved writes to a foreign project’s Claude Code files. The absence of exfiltration does not remove the policy-defined install-time agent-control hijack risk. - **Files touched:** bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, templates/kickstart/.claude/snippets.md, projectRoot/CLAUDE.md, projectRoot/.claude/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js automatically., bin/postinstall.js targets a parent package root, not the installed package., Blank/EOF prompt response is treated as approval., Postinstall copies CLAUDE.md and .claude/ into that foreign project root. - **Evidence against:** Writes do not overwrite existing CLAUDE.md or .claude/., Inspected AI templates contain framework guidance and no exfiltration or remote-command configuration., No install-time network or shell execution is present. ## Public findings ### 1.
