Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Package-provided instructions or settings can be added to the consuming project's AI-agent control surface without an affirmative opt-in. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.51.8 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook performs project-root writes to Claude Code control files and treats the default empty response as consent. This meets the policy for blocking unconsented postinstall mutation of a foreign AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-12T03:40:13.122Z - **Finished:** 2026-10-12T03:40:54.778Z - **Download time:** 1029 ms - **Static scan time:** 1148 ms - **AI review time:** 39477 ms - **Total time:** 41656 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 npm postinstall hook can write package-provided AI assistance files into the consuming project, including CLAUDE.md and .claude/. Its prompt defaults to copying unless the user explicitly declines. - **Trigger:** npm runs the package postinstall hook in a node\_modules install context outside CI or the package's development tree. - **Impact:** Package-provided instructions or settings can be added to the consuming project's AI-agent control surface without an affirmative opt-in. - **Evidence paths:** package.json, bin/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:40:54.778Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook prompts for permission, then copies files into the project root for any response other than “n” or “no”; an empty response proceeds with copying. - **Attack narrative:** The package declares an automatic postinstall hook. In an eligible install context, the hook asks whether to copy AI assistance files but proceeds on an empty or otherwise non-negative answer, then writes CLAUDE.md and .claude/ into the project root when they are absent. This is unconsented install-time mutation of an AI-agent control surface. - **Rationale:** The postinstall hook performs project-root writes to Claude Code control files and treats the default empty response as consent. This meets the policy for blocking unconsented postinstall mutation of a foreign AI-agent control surface. - **Files touched:** CLAUDE.md, .claude/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs bin/postinstall.js automatically after installation., The install hook asks whether to copy AI assistance files, but treats every answer except “n” or “no”—including an empty response—as approval., The hook copies CLAUDE.md and creates a .claude directory in the consuming project when those destinations do not exist., The CLI also exposes a separately prompted setup-ai command that copies these files., templates/view-template/view.js contains ordinary view lifecycle examples; it does not explain or mitigate the install-time writes. - **Evidence against:** The install hook skips development and CI contexts and checks that it is running from node\_modules., The file-copy operations preserve existing destination files and directories. ## Affected versions and remediation This report applies to domma-js@0.51.8. - Avoid installing domma-js@0.51.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
