Package instructions can be automatically discovered by Claude, Pi, and generic agent harnesses. - **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:** 2.3.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically adds its skills and agents to several AI-agent discovery directories. No credential theft or network exfiltration was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-27T06:25:09.823Z - **Finished:** 2026-08-27T06:27:09.307Z - **Download time:** 508 ms - **Static scan time:** 1604 ms - **AI review time:** 117371 ms - **Total time:** 119484 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically adds its skills and agents to several AI-agent discovery directories. No credential theft or network exfiltration was confirmed. - **Trigger:** npm install, including global installation, runs postinstall. - **Impact:** Package instructions can be automatically discovered by Claude, Pi, and generic agent harnesses. - **Evidence paths:** package.json, scripts/install-skill.sh, scripts/uninstall-skill.sh, skills/cw-cli/SKILL.md, dist/handlers/setup-agent-dir.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T06:27:09.307Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall symlink creation in AI-agent skill and agent directories. - **Attack narrative:** A normal npm installation invokes the package postinstall script. That script symlinks package-supplied skills and agent files into discovery locations used by several AI-agent products, including Claude and Pi. The installation occurs without an explicit setup command and can alter which instructions those agents load. The script protects existing non-symlink files and no data theft or remote payload behavior was found, but the automatic broad control-surface mutation is sufficient for blocking. - **Rationale:** The package performs unconsented postinstall mutation of multiple foreign AI-agent control surfaces. This meets the firewall block policy despite the absence of confirmed exfiltration or remote payload execution. - **Files touched:** scripts/install-skill.sh, skills/cw-cli, skills/tech-design, $HOME/.agents/skills, $HOME/.claude/skills, $HOME/.agents/agents, $HOME/.pi/agent/agents, $HOME/.claude/agents ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook runs a shell script automatically during installation., The install script creates package-controlled symlinks in Claude, Pi, and generic agent skill and agent directories., This changes several third-party AI-agent control surfaces without an explicit user command. - **Evidence against:** The installer only links packaged skills and agent files and skips existing non-symlink user files., No network calls, credential collection, or payload download were found in the inspected lifecycle scripts. ## Public findings ### 1.
