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:** 0.51.7 - **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 install-time agent configuration setup is guarded by an interactive prompt, avoids overwriting existing destinations, and is also available through a user-invoked CLI command. This is a guarded first-party agent setup capability, warranting a warning rather than a block; the scanner's malware label is not supported by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-12T03:39:55.067Z - **Finished:** 2026-10-12T03:40:54.694Z - **Download time:** 2288 ms - **Static scan time:** 1181 ms - **AI review time:** 56157 ms - **Total time:** 59627 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 place package-provided Claude Code guidance and settings in the consuming project. The copy is gated by a prompt and skips destinations that already exist, so the inspected source does not establish an unconsented control-surface attack. - **Trigger:** Installing the package under node\_modules outside a CI environment, followed by an affirmative response or accepting the default yes. - **Impact:** The project may gain package-provided Claude Code guidance and settings. No exfiltration, remote execution, or overwrite behavior was established from the inspected source. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:40:54.694Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook locates the project root and copies the package's CLAUDE.md and .claude directory only when those destinations are absent; the CLI also offers an explicit setup-ai command. - **Rationale:** The install-time agent configuration setup is guarded by an interactive prompt, avoids overwriting existing destinations, and is also available through a user-invoked CLI command. This is a guarded first-party agent setup capability, warranting a warning rather than a block; the scanner's malware label is not supported by the inspected source. - **Files touched:** CLAUDE.md, .claude/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs bin/postinstall.js automatically after installation., The hook gates itself on installation under node\_modules and skips CI environments., The hook asks whether to copy AI assistance files; answering no cancels the operation., After consent, the hook copies package-provided Claude Code files only when corresponding project paths do not already exist., The CLI exposes setup-ai as a separate command and prompts before copying its AI assistance files., The flagged view template only logs route and mount events; its request example is commented out. - **Evidence against:** The postinstall hook reaches the consumer project root and can create CLAUDE.md and .claude configuration during dependency installation after an affirmative or default-yes response. ## Affected versions and remediation This report applies to domma-js@0.51.7. - Review the evidence and your use of domma-js@0.51.7 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.
