Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The install-time hook can modify Claude-related project configuration, and its yes-by-default prompt leaves a real consent concern. The behavior is limited to package-owned setup files, so it warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-12T03:40:46.744Z - **Finished:** 2026-10-12T03:41:20.855Z - **Download time:** 510 ms - **Static scan time:** 1196 ms - **AI review time:** 32403 ms - **Total time:** 34111 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The install hook can add package-provided Claude assistance files to a consumer project. Because the prompt defaults to yes, pressing Enter proceeds with the project configuration change. - **Trigger:** Installing the package in a node\_modules context outside CI, followed by an empty or affirmative response to the prompt. - **Impact:** This may add Claude-specific project guidance and settings. The source supports a guarded, package-owned setup capability, but no separate attack behavior was established. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js, templates/view-template/view.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:41:20.855Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies CLAUDE.md and, if absent, the package's .claude directory and other assistance files into the project root. - **Rationale:** The install-time hook can modify Claude-related project configuration, and its yes-by-default prompt leaves a real consent concern. The behavior is limited to package-owned setup files, so it warrants a warning rather than a publish block. - **Files touched:** CLAUDE.md, .claude/, blueprints/, types/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs bin/postinstall.js during installation., The hook runs in a node\_modules install context, asks whether to copy AI assistance files, and stops when the user answers no. Its prompt defaults to yes, so an empty response proceeds., The hook copies the package's .claude directory into the project only if that destination does not already exist., The CLI exposes setup-ai as a separate command and also prompts before copying files., The flagged view template contains ordinary view lifecycle examples, not an attack behavior. - **Evidence against:** The reviewed source shows no confirmed data theft, remote payload execution, or destructive behavior. ## Affected versions and remediation This report applies to domma-js@0.51.10. - Review the evidence and your use of domma-js@0.51.10 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
