CRITICAL

npm lifecycle script — runs automatically on install

repo/package.json:34

    "clean": "rm -rf packages/*/dist apps/*/dist dist-mcp/ dist-dashboard/",
    "postinstall": "node scripts/postinstall.js",
    "build:mcp": "rm -rf dist-mcp && npx esbuild apps/cli/src/mcp-server-sdk.ts --bundle --platform=node --target=node22 --outfile=dist-mcp/mcp-server.js --external:ws --external:@modelcontextprotocol/sdk --tsconfig=tsconfig.json && cp -r packages/orchestrator/src/default-skills dist-mcp/default-skills && cp -r packages/orchestrator/src/default-rules dist-mcp/default-rul

Why was this flagged?

npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.
