A package installation can alter Claude, Cursor, and other agent control surfaces with remotely supplied content. - **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:** 2.0.0 - **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 downloads and force-installs remote skills into detected third-party AI-agent directories. It also removes legacy skills and state without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T08:53:29.259Z - **Finished:** 2026-08-28T08:55:36.531Z - **Download time:** 502 ms - **Static scan time:** 451 ms - **AI review time:** 126317 ms - **Total time:** 127272 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically downloads and force-installs remote skills into detected third-party AI-agent directories. It also removes legacy skills and state without an explicit user command. - **Trigger:** npm postinstall - **Impact:** A package installation can alter Claude, Cursor, and other agent control surfaces with remotely supplied content. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/bundle.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T08:55:36.531Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote skill download and forced multi-agent directory mutation - **Attack narrative:** The npm postinstall hook writes a Skillshub configuration and calls the bundled CLI with --force for seven skills. The CLI fetches remote artifacts and installs them across detected AI-agent directories, including Claude and Cursor, without a user command. The hook also deletes legacy skill and state locations. This is an unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The install hook performs a concrete remote-content deployment into multiple third-party AI-agent directories and deletes related user state. This meets the blocking policy for unconsented postinstall mutation of a broad AI-agent control surface. - **Files touched:** scripts/postinstall.cjs, dist/bundle.js, ~/.yunke/skillshub.json, ~/.agents/skills, ~/.claude/skills, ~/.cursor/skills, ~/.workbuddy/skills, ~/.omnicli - **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:** The postinstall hook automatically invokes forced skill installation., The bundled installer downloads skills and distributes them to detected AI client directories, including Claude and Cursor., Installation writes configuration under the user home directory and can remove legacy agent skills and directories., Remote skill content is fetched during installation without user invocation. - **Evidence against:** The package uses a named same-vendor Skillshub service., Downloaded archives have a SHA-256 check when the remote manifest provides one., No credential harvesting or unrelated data exfiltration was confirmed in the inspected files. ## Public findings ### 1.
