Modifies a foreign project’s AI-agent control surface, influencing 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:** 0.37.0 - **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 attempts to add Claude Code instruction and settings files outside the package. The prompt treats an empty answer as acceptance and writes only when targets do not already exist. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-08T11:36:10.411Z - **Finished:** 2026-08-08T11:37:06.392Z - **Download time:** 504 ms - **Static scan time:** 768 ms - **AI review time:** 54707 ms - **Total time:** 55981 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code attempts to add Claude Code instruction and settings files outside the package. The prompt treats an empty answer as acceptance and writes only when targets do not already exist. - **Trigger:** npm install in a node\_modules context - **Impact:** Modifies a foreign project’s AI-agent control surface, influencing subsequent agent behavior. - **Evidence paths:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-08T11:37:06.392Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies AI-agent instruction/configuration templates into a parent project - **Attack narrative:** The package’s postinstall hook runs automatically, presents a default-yes prompt, and can copy package-provided CLAUDE.md and .claude settings into the consuming project. These files are outside the package and shape third-party AI-agent behavior. Although the contents are framework-focused and no exfiltration was found, install-time mutation of this foreign agent control surface is concrete and unconsented by default. - **Rationale:** Source inspection confirms install-time mutation of a consuming project’s Claude control files. This meets the firewall block boundary despite otherwise benign template content. - **Files touched:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, CLAUDE.md, .claude/ ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js on install., bin/postinstall.js prompts with default Y and copies into the consuming project., It creates project-root CLAUDE.md and .claude/ from package templates., The copied files direct Claude/Cursor behavior and conventions. - **Evidence against:** No credential harvesting, exfiltration, remote payload, or destructive code found., AI template content is framework guidance; no hidden commands or external execution., CLI shell use is limited to explicit serve-time live-server installation. ## Public findings ### 1.
