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 package defines an install-time hook that offers to write package-owned Claude Code files into the consumer project, creating a concrete agent configuration capability. The prompt and destination checks make this a guarded first-party setup, so the appropriate result is a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-12T03:37:28.372Z - **Finished:** 2026-10-12T03:38:03.318Z - **Download time:** 506 ms - **Static scan time:** 1185 ms - **AI review time:** 33253 ms - **Total time:** 34946 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-owned Claude Code assistance files to the consumer project after prompting. This is a guarded first-party agent setup capability, not a confirmed attack. - **Trigger:** Package installation in a node\_modules directory outside CI, followed by accepting the prompt or providing an answer other than no. - **Impact:** May add project instructions and Claude Code settings that affect later agent use; the inspected code does not establish malicious control or data theft. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:38:03.318Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies CLAUDE.md, .claude, blueprints, and types from the package template into project paths when those destinations do not already exist. - **Rationale:** The package defines an install-time hook that offers to write package-owned Claude Code files into the consumer project, creating a concrete agent configuration capability. The prompt and destination checks make this a guarded first-party setup, so the appropriate result is a warning rather than a block. - **Files touched:** package.json, bin/postinstall.js, bin/domma-cli.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json runs bin/postinstall.js during installation., The install hook runs in a node\_modules context outside CI and prompts before copying AI assistance files; answering no skips the copy., The hook copies package-provided Claude Code files into the consumer project only when the destination paths do not already exist., The CLI exposes the same setup as an explicit setup-ai command, asks before copying, and does not overwrite existing destinations. - **Evidence against:** Inspected code shows no credential collection, network transmission, or remote payload execution in the flagged install and setup paths. ## Affected versions and remediation This report applies to domma-js@0.51.0. - Review the evidence and your use of domma-js@0.51.0 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.
