Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically mutates global Claude, Codex, OpenCode, and Gemini/Antigravity agent surfaces. It also alters the consuming repository's .gitignore. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T09:28:56.987Z - **Finished:** 2026-09-08T09:30:30.100Z - **Download time:** 764 ms - **Static scan time:** 4913 ms - **AI review time:** 87434 ms - **Total time:** 93113 ms The recorded confidence comes from the underlying analysis.

It also alters the consuming repository's .gitignore. - **Trigger:** npm postinstall during package installation - **Impact:** An install can add or overwrite AI-agent control files outside the package without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T09:30:30.100Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic deployment of global agent commands, skills, plugins, and configuration - **Attack narrative:** The postinstall hook launches two deployers that write global Claude and Codex skills, merge OpenCode configuration, and install Gemini/Antigravity plugins. The shared writer creates directories and overwrites targets. This occurs automatically on installation and is accompanied by a consumer-project .gitignore mutation, creating an unconsented broad AI-agent control-surface change. - **Rationale:** This is concrete automatic install-time mutation of foreign, global AI-agent control surfaces and the consuming project. The lack of observed network exfiltration does not remove that install-hook abuse. - **Files touched:** $HOME/.claude/commands/audit-code.md, $HOME/.codex/skills/audit-code/SKILL.md, $HOME/.codex/skills/remediate-code/SKILL.md, $HOME/.config/opencode/opencode.json, $HOME/.gemini/config/plugins/audit-code/plugin.json, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The npm postinstall hook automatically launches both host-asset deployers., The audit deployer writes Claude and Codex global command and skill files., The remediate deployer also writes global Codex files and OpenCode configuration., Shared helpers create parent directories and overwrite generated files., Postinstall also changes the consuming repository's .gitignore. - **Evidence against:** No network endpoint or credential-exfiltration path was found in the inspected entry points., package.json has no runtime dependency on audit-tools itself. ## Affected versions and remediation This report applies to audit-tools@0.51.7. - Avoid installing audit-tools@0.51.7. 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.
