The package changes broad AI-agent control surfaces in the consumer project without explicit user setup. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.7.45 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies the consumer project's AI-agent configuration. It installs skills across four agent directories and expands Claude Code command permissions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-03T19:25:46.682Z - **Finished:** 2026-09-03T19:26:56.428Z - **Download time:** 519 ms - **Static scan time:** 4754 ms - **AI review time:** 64472 ms - **Total time:** 69746 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies the consumer project's AI-agent configuration. It installs skills across four agent directories and expands Claude Code command permissions. - **Trigger:** npm installation runs postinstall. - **Impact:** The package changes broad AI-agent control surfaces in the consumer project without explicit user setup. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T19:26:56.428Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unprompted cross-agent configuration and permission mutation. - **Attack narrative:** On installation, the postinstall hook finds the consumer project and invokes setup with confirmation disabled. Setup writes package skills into Cursor, Claude Code, Codex, and OpenClaw directories, then merges a command allowlist into the consumer's Claude Code settings. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic postinstall chain performs broad consumer-project agent configuration and permission changes with no explicit user command or consent. This meets the install-control-surface blocking policy. - **Files touched:** .cursor/skills/sdd-flow-kit/SKILL.md, .claude/skills/sdd-flow-kit/SKILL.md, .codex/skills/sdd-flow-kit/SKILL.md, .openclaw/skills/sdd-flow-kit/SKILL.md, .claude/settings.local.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook automatically., Postinstall locates the consumer project and calls setup without prompting., Setup installs skills for Cursor, Claude Code, Codex, and OpenClaw., Setup automatically adds broad Claude Code command permissions. - **Evidence against:** No credential harvesting or secret exfiltration was found., No package-owned fixed network endpoint was found. ## Public findings ### 1.
