A dependency installation can alter how multiple AI coding agents operate in the consumer project and reduce command-confirmation protections. - **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:** 1.8.1 - **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. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes the consuming project's AI-agent configuration and permissions. It writes workflow material into several agent control directories and broadens Claude Code command approval rules. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T12:52:07.644Z - **Finished:** 2026-09-12T12:53:20.475Z - **Download time:** 505 ms - **Static scan time:** 3583 ms - **AI review time:** 68742 ms - **Total time:** 72831 ms The recorded confidence comes from the underlying analysis.

It writes workflow material into several agent control directories and broadens Claude Code command approval rules. - **Trigger:** npm installation runs postinstall. - **Impact:** A dependency installation can alter how multiple AI coding agents operate in the consumer project and reduce command-confirmation protections. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T12:53:20.475Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unprompted cross-agent control-surface and permission mutation. - **Attack narrative:** On installation, the lifecycle hook identifies the consuming project, selects an agent, and invokes setup with confirmation bypassed. Setup writes skills and trigger rules into four different AI-agent directories, changes Cursor rules, and merges a broad Claude Code command allowlist. These are foreign project control surfaces changed automatically by a dependency install. - **Rationale:** This is an unconsented postinstall mutation of broad AI-agent control surfaces in the consumer project. The lack of network theft does not remove the concrete install-time control-hijack risk. - **Files touched:** package.json, .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, .cursor/rules/00-sdd-flow-kit-version-trigger.mdc, .cursor/rules/sdd-flow-kit-gates.mdc, .claude/settings.local.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., Postinstall resolves a consumer project and calls setup without a prompt or dry-run., Setup writes skills and trigger rules across Cursor, Claude Code, Codex, and OpenClaw project control directories., Setup silently broadens Claude Code command permissions, including npm, npx, pnpm, node, copy, move, chmod, and mkdir., Postinstall invokes project setup with automatic confirmation and dry-run disabled. - **Evidence against:** No external network endpoint or credential exfiltration was found in the inspected install path., The observed behavior is visible source code rather than an obfuscated payload. ## Affected versions and remediation This report applies to sdd-flow-kit@1.8.1. - Avoid installing sdd-flow-kit@1.8.1. 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.
