It writes workflow skills for four agents and grants Claude Code a command allowlist without an explicit setup command. - **Trigger:** npm postinstall during package installation. - **Impact:** A dependency installation can persist instructions across Cursor, Claude Code, Codex, and OpenClaw, while reducing Claude Code command confirmations. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T07:34:54.683Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent skill installation and Claude Code permission allowlist mutation. - **Attack narrative:** The package’s postinstall hook resolves the consuming project and invokes setup with confirmation disabled. Setup writes skills and trigger instructions into four different AI-agent directories, then merges a Claude Code permission allowlist that permits package managers, Node, file changes, and chmod. This is an unconsented install-time mutation of foreign AI-agent control surfaces, so a normal dependency installation changes future agent behavior and approval boundaries. - **Rationale:** Direct inspection confirms unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the blocking policy even though no network exfiltration was found in the install path. - **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:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs project setup without user confirmation., Setup writes skills into Cursor, Claude Code, Codex, and OpenClaw project control directories., Setup adds version-trigger skills for all four agent platforms., Setup silently merges a broad Claude Code command allowlist, including npm, npx, node, and chmod. - **Evidence against:** No postinstall network endpoint or credential-exfiltration path was found in the inspected install code., The observed writes are packaged workflow content rather than an encrypted or remotely fetched payload. ## Public findings ### 1.
