It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. npm postinstall unconditionally installs WoWok skill files into every default AI-client skill root and, unless opted out, globally installs @wowok/agent-mcp and writes that launcher into client MCP configs. It can also kill matching local MCP processes so clients reload the new server. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-28T00:17:08.930Z - **Finished:** 2026-09-28T00:18:31.576Z - **Download time:** 503 ms - **Static scan time:** 474 ms - **AI review time:** 81668 ms - **Total time:** 82646 ms The recorded confidence comes from the underlying analysis.

It can also kill matching local MCP processes so clients reload the new server. - **Trigger:** npm postinstall via scripts/install.js calling runLifecycle. - **Impact:** A normal install mutates foreign agent skill and MCP control files and can replace or restart a globally installed agent server without a separate user command. - **Evidence paths:** package.json, scripts/install.js, dist/installer.js, dist/targets.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T00:18:31.576Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default target list covers many third-party clients. Skill markdown is copied into user skill directories, npm install -g fetches @wowok/agent-mcp, and MCP JSON or TOML configs are updated to launch it. A changed install then signals pkill or PowerShell Stop-Process. - **Attack narrative:** Installing @wowok/skills runs postinstall, which loads the shared installer and treats every listed AI client as a target. It creates user skill directories and writes the package skill files into them, including Claude, Cursor, Copilot, and Grok paths. Unless an environment flag skips MCP setup, it also queries npm, globally installs @wowok/agent-mcp, and appends a launcher entry to client config files such as the Claude user config. If that server changes, the hook force-stops matching Node processes so the clients start the new binary. - **Rationale:** The postinstall hook writes this package into many third-party AI skill directories and registers a second global package in their MCP configs without a separate user command. That is unconsented mutation of a broad foreign agent control surface, so the release should be blocked. - **Files touched:** .claude/skills, ~/.claude.json, .mcp.json, .agents/skills, .cursor/skills, .grok/skills, .github/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 92.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs node scripts/install.js from the npm postinstall hook., scripts/install.js loads dist/installer.js and calls runLifecycle with the npm lifecycle event., On postinstall, runLifecycle selects every default client target and installs skills into user-scope directories without a separate user command., installSkillsInto creates those roots and writes each shipped SKILL.md, including directories used by other AI clients., The same hook globally installs @wowok/agent-mcp and registers its launcher in client MCP configs such as the user Claude config., After an MCP change it force-stops matching Node processes with pkill or an encoded PowerShell Stop-Process command. - **Evidence against:** MCP registration skips a client when no install marker and no existing config file are present., WOWOK\_SKILLS\_TARGETS and WOWOK\_SKILLS\_NO\_MCP can narrow targets or skip MCP management, but both default to the broad path., No credential harvesting, hidden outbound URL, or eval of a remote payload appears in the install path. ## Affected versions and remediation This report applies to @wowok/skills@3.2.7. - Avoid installing @wowok/skills@3.2.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
