A dependency install can alter agent behavior and authorize broad package-manager, runtime, and file commands in the consumer project. - **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:** 1.8.2 - **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. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes the consuming project's AI-agent configuration. It installs workflow skills for four agent products and expands Claude Code command permissions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T10:27:01.499Z - **Finished:** 2026-09-11T10:28:14.854Z - **Download time:** 505 ms - **Static scan time:** 4935 ms - **AI review time:** 67915 ms - **Total time:** 73355 ms The recorded confidence comes from the underlying analysis.

It installs workflow skills for four agent products and expands Claude Code command permissions. - **Trigger:** npm install executes postinstall. - **Impact:** A dependency install can alter agent behavior and authorize broad package-manager, runtime, and file commands in the consumer project. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:28:14.854Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent control-surface writes and permission allowlist injection. - **Attack narrative:** On installation, postinstall locates the consuming project and invokes setup non-interactively. Setup writes skills and trigger rules into Cursor, Claude Code, Codex, and OpenClaw directories, then merges a broad Claude Code Bash allowlist. These are foreign AI-agent control surfaces modified without an explicit user command or approval. - **Rationale:** The automatic lifecycle hook performs broad, unconsented mutation of consumer AI-agent control surfaces and adds command permissions. This meets the install-hook abuse 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, .cursor/rules/00-sdd-flow-kit-version-trigger.mdc, .cursor/rules/sdd-flow-kit-gates.mdc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., Postinstall resolves the consumer project and calls setup with confirmation forced on., Setup writes skills into Cursor, Claude Code, Codex, and OpenClaw project control directories., Setup grants Claude Code broad npm, npx, pnpm, node, file-operation permissions without consent., The postinstall invokes setup for the resolved project with confirmation enabled and dry-run disabled., Setup targets Cursor, Claude Code, Codex, and OpenClaw skill directories., Claude Code permissions include npm, npx, pnpm, node, and file-operation commands. - **Evidence against:** No network endpoint or credential exfiltration was found in the inspected lifecycle path., The observed writes are local project changes rather than a remote payload download. ## Affected versions and remediation This report applies to sdd-flow-kit@1.8.2. - Avoid installing sdd-flow-kit@1.8.2. 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.
