Unconsented modification of AI-agent instruction/control surfaces. - **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:** 1.2.0 - **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 invokes a postinstall script that copies an agent skill into detected cross-vendor agent directories. It also creates a project .agents skill directory when none is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-19T13:29:48.013Z - **Finished:** 2026-08-19T13:30:46.124Z - **Download time:** 251 ms - **Static scan time:** 90 ms - **AI review time:** 57769 ms - **Total time:** 58111 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package invokes a postinstall script that copies an agent skill into detected cross-vendor agent directories. It also creates a project .agents skill directory when none is present. - **Trigger:** npm install (postinstall) - **Impact:** Unconsented modification of AI-agent instruction/control surfaces. - **Evidence paths:** package.json, scripts/install.js, skills/wiki-manager/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-19T13:30:46.124Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent skill deployment - **Attack narrative:** During npm installation, the lifecycle hook runs scripts/install.js. It recursively copies the bundled wiki-manager skill into detected agent-runtime skill directories; for normal project installs it targets existing runtime directories and otherwise creates .agents/skills. This changes AI-agent behavior without requiring an explicit package command. - **Rationale:** The package performs unconsented postinstall mutation of foreign and broad AI-agent control surfaces, including a fallback that creates one. This meets the firewall block policy despite no observed exfiltration or network behavior. - **Files touched:** package.json, scripts/install.js, skills/wiki-manager/, ~/.claude/skills/wiki-manager, ~/.config/opencode/skills/wiki-manager, ~/.agents/skills/wiki-manager, \/.agents/skills/wiki-manager ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install.js automatically as postinstall., Installer targets multiple foreign agent skill directories, including Claude, Codex, Cursor, Gemini, and Windsurf., On ordinary project install it copies the bundled skill into every detected agent runtime., When none exists, postinstall creates .agents/skills/wiki-manager without user action. - **Evidence against:** No network, credential harvesting, remote payload, or shell execution was found., The copied skill is readable source, but its install-time placement still mutates broad agent control surfaces. ## Public findings ### 1.
