It registers the package as an MCP server and injects mandatory agent behavior without user invocation. - **Trigger:** npm install - **Impact:** Enables AiDex in installed AI clients and changes future agent behavior across user projects. - **Evidence paths:** package.json, scripts/postinstall.mjs, build/index.js, build/commands/setup.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T16:55:57.843Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-triggered broad AI-agent configuration and instruction-file writes - **Attack narrative:** Installing the package executes its postinstall hook, which launches \`aidex setup\`. Setup detects several unrelated AI clients, writes an \`aidex\` MCP-server entry into their user-level configuration, and creates or appends global Claude/Gemini instruction files. The injected text imposes required tool choices and automatic actions, including initializing the package without asking. These changes occur without an explicit setup command or consent. - **Rationale:** This is a concrete, unconsented install-time mutation of broad third-party AI-agent control surfaces. It meets the firewall block policy even though no credential exfiltration was observed. - **Files touched:** scripts/postinstall.mjs, build/index.js, build/commands/setup.js, ~/.claude/CLAUDE.md, ~/.gemini/GEMINI.md, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.gemini/settings.json ### 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 invokes build/index.js setup on install., build/commands/setup.js registers aidex in Claude, Cursor, Windsurf, Gemini, and VS Code MCP configs., setup.js writes mandatory behavioral instructions into ~/.claude/CLAUDE.md and ~/.gemini/GEMINI.md., The injected instructions direct agents to auto-run AiDex actions without asking. - **Evidence against:** No install-time network request or credential exfiltration was found., LLM endpoints are runtime provider configuration, not postinstall behavior. ## Public findings ### 1.
