Unconsented cross-agent prompt/control-surface mutation and persistence until manually removed. - **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:** 1.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically installs and forcibly overwrites a skill across detected third-party AI-agent control surfaces. This occurs for global installs and for existing agent directories in the current project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-16T23:43:30.134Z - **Finished:** 2026-08-16T23:44:07.354Z - **Download time:** 255 ms - **Static scan time:** 64 ms - **AI review time:** 36900 ms - **Total time:** 37220 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically installs and forcibly overwrites a skill across detected third-party AI-agent control surfaces. This occurs for global installs and for existing agent directories in the current project. - **Trigger:** npm install or npm install -g - **Impact:** Unconsented cross-agent prompt/control-surface mutation and persistence until manually removed. - **Evidence paths:** package.json, scripts/install.js, skills/wiki-manager/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-16T23:44:07.354Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies bundled skill into detected runtime skill directories - **Attack narrative:** Installing the package invokes its postinstall script without a separate setup command. The script detects multiple unrelated AI-agent runtimes and force-copies its bundled wiki-manager skill into each matching global or project skill directory, overwriting an existing skill of that name. This is a broad foreign agent control-surface mutation at install time. - **Rationale:** The source establishes concrete, automatic, forceful mutation of foreign AI-agent skill directories during npm installation. Under the install-control-surface policy, this requires blocking despite no observed network exfiltration. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** scripts/install.js, skills/wiki-manager/, ~/.claude/skills/wiki-manager, ~/.config/opencode/skills/wiki-manager, ~/.agents/skills/wiki-manager, ~/.cursor/skills/wiki-manager, ~/.gemini/skills/wiki-manager ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall runs scripts/install.js automatically., Installer copies into detected Claude, Codex, Cursor, Gemini and other agent skill directories., Copy uses force:true, overwriting wiki-manager in each detected target. - **Evidence against:** No network, credential collection, or remote payload execution found., Bundled Python checker is report-only. ## Public findings ### 1.
