Package-authored skills become available to Claude Code and existing matching skill files may be overwritten. - **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:** 0.13.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm installation, the package runs a postinstall script that copies packaged skills into the user's Claude Code skills directory. This is an unconsented mutation of a broad AI-agent control surface and can overwrite matching existing skills. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-14T12:34:02.457Z - **Finished:** 2026-08-14T12:34:53.912Z - **Download time:** 1770 ms - **Static scan time:** 3943 ms - **AI review time:** 45740 ms - **Total time:** 51455 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package runs a postinstall script that copies packaged skills into the user's Claude Code skills directory. This is an unconsented mutation of a broad AI-agent control surface and can overwrite matching existing skills. - **Trigger:** npm install (including non-global installs) without EMDEE\_SKIP\_POSTINSTALL=1 - **Impact:** Package-authored skills become available to Claude Code and existing matching skill files may be overwritten. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/skills-install.ts, dist/cli/skills-install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T12:34:53.912Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall recursively copies package-controlled Markdown into ~/.claude/skills - **Attack narrative:** Installing the package invokes scripts/postinstall.mjs, which launches the bundled skills installer by default. That installer targets ~/.claude/skills and copies package-controlled Markdown skill files recursively, overwriting existing matching files. The behavior is not limited to a user-invoked setup command or verified global installation, so package installation mutates a foreign, behavior-bearing AI-agent directory. - **Rationale:** The confirmed postinstall mutation of ~/.claude/skills meets the policy threshold for an unconsented foreign/broad AI-agent control-surface write. The reverse-shell and credential-exfiltration hints were not confirmed in the inspected auth sources. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, skills/, ~/.claude/skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json installs a postinstall hook., The hook automatically runs the skills installer unless an opt-out environment variable is set., The installer defaults to the broad Claude Code skills directory and recursively copies package Markdown there., The copy operation overwrites existing skill files during installation. - **Evidence against:** OAuth network calls are in explicit login/whoami commands and use a loopback PKCE callback., No credential harvesting or reverse-shell behavior was confirmed in inspected auth sources. ## Public findings ### 1.
