Unconsented install-time modification of AI-agent commands available in the project or globally. - **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:** 0.20260708.2 - **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. Source inspection confirms automatic postinstall writes into .claude, which meets the policy threshold for unconsented install-time AI-agent control-surface mutation. The behavior appears package-aligned and non-exfiltrating, but install-time agent command installation is enough to block under the stated boundary. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-07-08T10:42:10.858Z - **Finished:** 2026-07-08T10:42:58.960Z - **Download time:** 504 ms - **Static scan time:** 29 ms - **AI review time:** 47568 ms - **Total time:** 48102 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 package automatically mutates a Claude Code control surface during npm postinstall. It installs package-supplied agent and command files into the installing project .claude directory, with an option for ~/.claude. - **Trigger:** npm install lifecycle postinstall or explicit bin invocation - **Impact:** Unconsented install-time modification of AI-agent commands available in the project or globally. - **Evidence paths:** package.json, bin/install.js, templates/commands/ux-audit.md, templates/commands/ui-audit.md, templates/commands/a11y-audit.md, templates/commands/full-audit.md, scripts/ux-audit-capture.mjs, scripts/a11y-audit-scan.mjs, scripts/build-html-reports.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-08T10:42:58.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies Claude Code agent/command templates - **Attack narrative:** Installing the package triggers npm postinstall, which runs bin/install.js. That script resolves the target to the installing project’s .claude directory by default, creates agents/ and commands/ directories, and copies bundled Claude Code agent and slash-command definitions there. This is disclosed and package-aligned, and no exfiltration or remote code payload is evident, but the mutation happens automatically during install against a broad AI-agent control surface. - **Rationale:** Source inspection confirms automatic postinstall writes into .claude, which meets the policy threshold for unconsented install-time AI-agent control-surface mutation. The behavior appears package-aligned and non-exfiltrating, but install-time agent command installation is enough to block under the stated boundary. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** package.json, bin/install.js, templates/agents/\*.md, templates/commands/\*.md, \/.claude/agents/\*.md, \/.claude/commands/\*.md, ~/.claude/agents/\*.md, ~/.claude/commands/\*.md - **Network endpoints:** https://registry.npmjs.org/ ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json defines postinstall: node bin/install.js, bin/install.js runs at install time and copies templates into \/.claude, bin/install.js also supports --global writes into ~/.claude, templates/commands/\*.md create Claude slash commands /ux-audit, /ui-audit, /a11y-audit, /full-audit - **Evidence against:** No credential/env harvesting found beyond INIT\_CWD target selection, No fixed exfiltration endpoint or remote payload download found, scripts only use Playwright/axe against user-supplied --url and write local audit outputs, README discloses .claude installation behavior ## Affected versions and remediation This report applies to @appfire-ux/audit-agent@0.20260708.2. - Avoid installing @appfire-ux/audit-agent@0.20260708.2. 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.
