It also modifies the consuming repository's .gitignore. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** A dependency installation changes foreign AI-agent control surfaces 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:** 2026-08-31T21:01:58.706Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time deployment of global agent assets and configuration. - **Attack narrative:** On npm installation, the manifest invokes a postinstall driver that launches two deployers. The audit deployer writes global Claude and Codex assets, merges a global OpenCode configuration, and installs a Gemini plugin; shared helpers create directories and overwrite files. The same lifecycle path also targets the consumer repository through INIT\_CWD to manage .gitignore. These changes occur without an explicit user setup command and affect several unrelated agent control surfaces. - **Rationale:** This package performs unconsented postinstall mutation of broad, foreign AI-agent control surfaces and the consumer project. That concrete lifecycle behavior meets the publish-block policy even without observed secret theft. - **Files touched:** ~/.claude/commands/audit-code.md, ~/.codex/skills/audit-code/SKILL.md, ~/.codex/skills/remediate-code/SKILL.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code, ~/.gemini/config/plugins/remediate-code, consumer-repo/.gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The registry postinstall hook automatically launches both host-asset deployers., The audit deployer writes commands and skills into global Claude and Codex directories., The deployers merge global OpenCode configuration and install global Gemini plugins., The shared writer creates parent directories and overwrites target files; postinstall also changes the consuming repository's .gitignore. - **Evidence against:** No credential collection or network exfiltration was confirmed in the inspected install path., The manifest has no runtime dependency on audit-tools itself. ## Public findings ### 1.
