Installing the package automatically deploys skills, commands, plugins, and configuration to several global AI-agent control surfaces. It also mutates the consumer repository's .gitignore. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-31T05:36:41.412Z - **Finished:** 2026-08-31T05:37:51.178Z - **Download time:** 514 ms - **Static scan time:** 4004 ms - **AI review time:** 65246 ms - **Total time:** 69766 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically deploys skills, commands, plugins, and configuration to several global AI-agent control surfaces. It also mutates the consumer repository's .gitignore. - **Trigger:** npm installation - **Impact:** A dependency installation can add or replace globally available AI-agent instructions and configuration without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T05:37:51.178Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic postinstall deployment of global agent assets and consumer-project mutation - **Attack narrative:** During npm installation, the manifest runs a launcher that executes both audit and remediation asset deployers. The audit deployer writes Claude commands and Codex skills into the user's home directory, while shared code creates directories and overwrites target files. The installer also deploys global OpenCode and plugin assets and changes the consuming repository's .gitignore. These are unconsented install-time mutations of broad, foreign AI-agent control surfaces. - **Rationale:** This is a concrete automatic postinstall chain that writes global AI-agent assets and modifies a consumer project. The absence of observed data theft does not neutralize the unconsented control-surface mutation. - **Files touched:** scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, ~/.claude/commands/audit-code.md, ~/.codex/skills/audit-code/SKILL.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code/plugin.json, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., The postinstall launches both agent-asset deployers., The audit deployer writes Claude and Codex assets under the user's home directory., The shared installer creates parent directories and overwrites generated files., The install script also changes the consuming repository's .gitignore. - **Evidence against:** No package runtime self-dependency is declared., No concrete secret-exfiltration or remote-payload endpoint was found in the inspected install path. ## Public findings ### 1.
