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 hook mutates a consumer project’s Claude configuration surface, but only after an interactive prompt and only for missing destinations. Classify this first-party lifecycle setup as a warning, with no confirmed malicious attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-12T03:37:28.612Z - **Finished:** 2026-10-12T03:37:54.435Z - **Download time:** 766 ms - **Static scan time:** 1126 ms - **AI review time:** 23929 ms - **Total time:** 25823 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 after an interactive prompt. This is a guarded, first-party agent configuration setup, so it warrants a warning but does not establish a concrete attack. - **Trigger:** Installing the package in a node\_modules context, outside development or CI; the hook then prompts the user. - **Impact:** It can add Claude Code context and settings to the consumer project; the inspected code does not establish credential exposure or remote control. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:37:54.435Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After the prompt, the hook copies files such as CLAUDE.md and .claude into the project only when the destinations do not already exist. - **Rationale:** The install hook mutates a consumer project’s Claude configuration surface, but only after an interactive prompt and only for missing destinations. Classify this first-party lifecycle setup as a warning, with no confirmed malicious attack behavior. - **Files touched:** CLAUDE.md, .claude/, blueprints/, types/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs bin/postinstall.js during installation., The install hook asks whether to copy AI assistance files and stops when the user answers no., The hook copies CLAUDE.md only when the project does not already contain it., The CLI also exposes setup-ai as an explicit command; its copy logic likewise preserves existing destinations. - **Evidence against:** The hook skips development and CI contexts and runs only when the working directory is under node\_modules., Inspected behavior shows first-party file copying, with no network request or remote payload execution. ## Affected versions and remediation This report applies to domma-js@0.51.3. - Review the evidence and your use of domma-js@0.51.3 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.
