That routine discovers standard Claude, Codex, and Cursor configuration directories and creates generated integration files there; it also adds an idea-gauntlet MCP server entry to Claude configuration. This is unconsented install-time mutation of foreign AI-agent control surfaces. - **Rationale:** The package’s install hook performs concrete writes to detected third-party AI-agent configuration roots rather than limiting setup to an explicit CLI command. This matches the blocking install-control-surface policy. - **Files touched:** package.json, dist/postinstall.js, dist/chunk-B7LL55D5.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes dist/postinstall.js., Postinstall invokes globalSetup in install mode., Setup auto-detects Claude, Codex, and Cursor config roots., Install writes generated integration files into detected roots., Install adds an idea-gauntlet MCP entry to Claude config. - **Evidence against:** Existing differing files are treated as conflicts unless force is set., Metadata-address strings are SSRF block rules, not requests. ## Public findings ### 1.
