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:** 0.44.4 - **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 scanner’s control-hijack hint is not supported by the inspected template: it contains Domma project preferences and guidance, with no agent hooks or remote skill channel. Because an npm install can invoke a postinstall flow that adds Claude configuration after a prompt, classify this as a warning-level agent extension lifecycle risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-12T03:33:20.481Z - **Finished:** 2026-10-12T03:33:56.205Z - **Download time:** 522 ms - **Static scan time:** 962 ms - **AI review time:** 34239 ms - **Total time:** 35724 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 first-party Claude guidance and project settings to the consumer project after prompting. This is a limited agent configuration setup capability; no concrete malicious behavior was identified. - **Trigger:** npm installation invokes the postinstall hook; the hook reaches its copy step after the prompt unless the response is “n” or “no”. - **Impact:** It can add package-authored guidance and Domma project preferences used by Claude Code. No agent execution hooks, credential access, or network behavior were found in the inspected configuration. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:33:56.205Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies CLAUDE.md and .claude files from the package template into project paths that do not already exist. The CLI exposes a separate interactive setup-ai command for the same files. - **Rationale:** The scanner’s control-hijack hint is not supported by the inspected template: it contains Domma project preferences and guidance, with no agent hooks or remote skill channel. Because an npm install can invoke a postinstall flow that adds Claude configuration after a prompt, classify this as a warning-level agent extension lifecycle risk. - **Files touched:** CLAUDE.md, .claude/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs bin/postinstall.js automatically after installation., The postinstall hook prompts before copying files, and an explicit “n” skips the operation., The hook copies first-party CLAUDE.md and .claude files only when the corresponding project paths do not already exist., The CLI routes setup-ai to an interactive handler that asks whether to continue before copying the same files., The supplied .claude settings contain Domma project preferences and style guidance; no agent hooks or remote skill channel are present in the inspected settings., templates/view-template/view.js contains only placeholder view callbacks and an example commented-out request. - **Evidence against:** The inspected lifecycle and template source shows no credential collection, network transmission, destructive action, or remote code execution. ## Affected versions and remediation This report applies to domma-js@0.44.4. - Review the evidence and your use of domma-js@0.44.4 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.
