Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.44.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 manifest activates an install-time hook that can add package-owned Claude assistance files to the consumer project after a prompt. This is a guarded agent extension setup, with no concrete malicious behavior established by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-12T03:33:20.142Z - **Finished:** 2026-10-12T03:33:42.594Z - **Download time:** 755 ms - **Static scan time:** 1109 ms - **AI review time:** 20586 ms - **Total time:** 22452 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 offers to copy this package’s Claude assistance files into the consuming project, including CLAUDE.md and related configuration. - **Trigger:** npm installation runs the postinstall hook in a node\_modules context, then the user accepts the prompt or presses Enter. - **Impact:** This can add package-authored guidance and configuration used by Claude Code; the inspected evidence does not establish broader control hijacking or data theft. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:33:42.594Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies package-supplied agent files to project-root destinations when those destinations do not already exist. - **Rationale:** The manifest activates an install-time hook that can add package-owned Claude assistance files to the consumer project after a prompt. This is a guarded agent extension setup, with no concrete malicious behavior established by the inspected source. - **Files touched:** CLAUDE.md, .claude/, blueprints/, types/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **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 postinstall script asks whether to copy AI assistance files, with “Y” as the default and only an explicit “n” or “no” skipping., The lifecycle code copies package-supplied CLAUDE.md into the consumer project root when absent., The CLI has a separate setup command that copies the same package-owned assistance files after a prompt., The flagged view template defines ordinary view lifecycle hooks and contains no agent-control behavior in the inspected excerpt. - **Evidence against:** The install-time behavior is limited to the package’s own Claude assistance files and skips existing destinations., The script’s prompt allows the user to decline; no network or credential transfer is shown in the inspected lifecycle code. ## Affected versions and remediation This report applies to domma-js@0.44.6. - Review the evidence and your use of domma-js@0.44.6 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.
