Install-time code can add Claude Code guidance files to the consuming project after an interactive default-yes prompt. No confirmed exfiltration, remote payload, or destructive behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T18:43:07.327Z - **Finished:** 2026-08-09T18:43:47.889Z - **Download time:** 760 ms - **Static scan time:** 744 ms - **AI review time:** 39057 ms - **Total time:** 40562 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code can add Claude Code guidance files to the consuming project after an interactive default-yes prompt. No confirmed exfiltration, remote payload, or destructive behavior was found. - **Trigger:** npm install in node\_modules outside CI; user accepts prompt or presses Enter - **Impact:** Changes a consuming project's AI-agent instruction surface. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-09T18:43:47.889Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies packaged Claude guidance into project root - **Rationale:** This is an install-time mutation of a foreign AI-agent control surface, so it warrants a warning under policy. The concrete source lacks malicious follow-on behavior, so a block is not justified. - **Files touched:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, project/CLAUDE.md, project/.claude/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js on install., bin/postinstall.js prompts during install, with Enter accepting the copy., Postinstall creates project-root CLAUDE.md and .claude/ if absent., Copied .claude/settings.json configures Claude-oriented project guidance. - **Evidence against:** Postinstall is CI-guarded and only copies packaged templates., No network, credential harvesting, or command execution is present in postinstall., CLI setup-ai repeats the same copy only after an explicit user command and confirmation., Template guidance contains framework documentation, not prompt override or exfiltration instructions. ## Public findings ### 1.
