It installs commands, skills, plugins, and merged OpenCode configuration without an explicit setup command. - **Trigger:** npm install of audit-tools@0.39.3 - **Impact:** A dependency installation can persist package-authored instructions and command permissions into Claude, Codex, OpenCode, and Antigravity environments. - **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:** 2026-08-08T09:09:55.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time global AI-agent configuration and skill deployment - **Attack narrative:** Installing the package invokes both deployers. They copy package-controlled prompts and skills into global Claude and Codex paths, merge commands, agents, and permissions into the user’s OpenCode config, and install Antigravity plugins; the audit deployer also writes into Claude’s external-plugin marketplace path. These are foreign, persistent AI-agent control surfaces changed without an explicit user setup command. - **Rationale:** The package’s automatic postinstall performs broad, persistent AI-agent control-surface writes outside the consuming project. This meets the blocking policy regardless of the absence of observed exfiltration. - **Files touched:** scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, ~/.claude/commands/audit-code.md, ~/.claude/commands/remediate-code.md, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code, ~/.codex/skills/audit-code, ~/.codex/skills/remediate-code, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code, ~/.gemini/config/plugins/remediate-code ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.mjs executes both host deployers during install., scripts/audit/postinstall.mjs writes global Claude, Codex, OpenCode, Antigravity, and Claude plugin assets., scripts/remediate/postinstall.mjs likewise installs global AI-agent assets., scripts/shared/install-host-assets.mjs creates directories and overwrites generated files. - **Evidence against:** No install-time network endpoint or credential exfiltration was found., OpenCode defaults broad edit/bash wildcards to "ask" and denies rm. ## Public findings ### 1.
