The installation does not require a separate user command. - **Trigger:** npm installation, through postinstall. - **Impact:** It can replace or add agent instructions and remove legacy CLI and skill files in the consumer environment. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/bundle.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T04:22:46.121Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Forced remote skill deployment and deletion across AI-agent control surfaces. - **Attack narrative:** On npm installation, postinstall writes configuration, removes legacy WorkBuddy and omni-cli content, then calls the bundled CLI with --force for seven skills. The bundled installer fetches remote artifacts and writes them to .agents/skills plus detected directories for several AI-agent clients. This is unconsented install-time mutation of broad agent control surfaces. - **Rationale:** The package has a concrete automatic lifecycle chain that deletes files and installs remotely obtained skills across multiple AI-agent directories. This meets the install-hook abuse block policy regardless of the absence of confirmed credential theft. - **Files touched:** scripts/postinstall.cjs, dist/bundle.js, ~/.yunke/skillshub.json, ~/.workbuddy/skills, ~/.omnicli, .agents/skills, .claude/skills, .openclaw/skills - **Network endpoints:** https://skillshub.yunke.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall hook automatically., The hook force-removes legacy CLI files and skill directories., The hook automatically invokes forced installation of seven remote skills., The bundle distributes downloads to multiple detected AI-agent skill directories, with .agents/skills as a fallback. - **Evidence against:** No runtime dependency on this package name is declared., No direct credential-harvesting code was confirmed in the inspected lifecycle hook. ## Affected versions and remediation This report applies to @yunkeai/yunke-cli@2.0.1. - Avoid installing @yunkeai/yunke-cli@2.0.1. 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.
