The package performs install-time Claude Code extension setup by copying its own audit agents and slash commands into .claude. This is a real agent lifecycle risk, but inspection found no confirmed exfiltration, destructive action, or remote code payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-08T09:50:28.946Z - **Finished:** 2026-07-08T09:51:42.445Z - **Download time:** 762 ms - **Static scan time:** 29 ms - **AI review time:** 72707 ms - **Total time:** 73499 ms ## Security analysis ### Published attack-surface review - **Summary:** The package performs install-time Claude Code extension setup by copying its own audit agents and slash commands into .claude. This is a real agent lifecycle risk, but inspection found no confirmed exfiltration, destructive action, or remote code payload. - **Trigger:** npm install/postinstall or explicit npx @appfire-ux/audit-agent command - **Impact:** Adds or overwrites audit agent instructions; later user-invoked commands may run npm tooling, Playwright scans, and write audit artifacts. - **Evidence paths:** package.json, bin/install.js, README.md, templates/agents/ux-auditor.md, templates/agents/ui-auditor.md, templates/agents/a11y-auditor.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:** 2026-07-08T09:51:42.445Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies bundled Claude agents/commands into an AI-agent control surface - **Rationale:** Static inspection confirms guarded first-party Claude audit-agent setup during postinstall, which should warn under the lifecycle policy. No concrete malicious chain such as credential harvesting, exfiltration, remote payload execution, persistence, or destructive behavior was found. - **Files touched:** .claude/agents/ux-auditor.md, .claude/agents/ui-auditor.md, .claude/agents/a11y-auditor.md, .claude/commands/ux-audit.md, .claude/commands/ui-audit.md, .claude/commands/a11y-audit.md, .claude/commands/full-audit.md, docs/audits/\*\* ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall: node bin/install.js., bin/install.js writes bundled templates into \/.claude/agents and \/.claude/commands, or ~/.claude with --global., Installer overwrites existing files via fs.copyFileSync without prompting., Installed agent prompts grant Bash/Write/WebFetch and instruct later npm update/install/npx/playwright actions during audits. - **Evidence against:** bin/install.js only copies local templates; no child\_process, eval, network fetch, or credential reads found., Templates are package-aligned UX/UI/a11y audit agents and commands, documented in README.md., Helper scripts require explicit user invocation and write screenshots/HTML/JSON audit outputs to user-specified or docs/audits paths., No hardcoded exfiltration endpoint or remote payload loading found; Playwright visits user-supplied audit URLs only., Prompts explicitly warn not to expose secrets/PII in reports or screenshots. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
