•Manifest-reachable source resolves another installed package, overwrites its runtime code, and injects package-defined remote behavior. dist/index.js: import { copyFile, mkdir, mkdtemp, readFile, readdir, rm, stat, writeFile } from "fs/promises"; return await (await fetch("https://mastra.ai/api/templates.json")).json(); await copyFile(targetFile, backupFile); await copyFile(sourceFile, targetFile); async function renameAndCopyFile(sourceFile, targetFile) { await copyFile(sourceFile, uniqueTargetFile); **Output Quality:** Production-ready code that follows Mastra ecosystem standards Follow this sequence for every coding task:
