[create-next-app] Skip interactive prompts when CLI flags are provided (#91840) When AI agents run `create-next-app` with explicit flags like `--typescript --tailwind --eslint --app --src-dir`, the CLI still enters interactive mode and prompts for any unspecified options: ``` ➜ npx create-next-app my-app --typescript --tailwind --eslint --app --src-dir --use-pnpm ✔ Would you like to use React Compiler? … No / Yes ✔ Would you like to customize the import alias (`@/*` by default)? … No / Yes ? Would you like to include AGENTS.md to guide coding agents to write up-to-date Next.js code? › No / Yes ``` Agents can sometimes answer these interactive prompts correctly, but often they can't. When they fail to navigate the prompts, they fall back to scaffolding the project themselves from scratch — generating files based on stale training data. This means they might initialize an app using deprecated patterns or pin to an older version of Next.js (e.g. 15) instead of the latest. Using `create-next-app` non-interactively is the best way to ensure agents always produce up-to-date scaffolding. Previously, `hasProvidedOptions` only skipped the initial "use recommended defaults?" meta-prompt but still showed individual prompts for each missing option. Now when any config flags are provided, all remaining options use the recommended defaults without prompting. The resolved defaults are printed to stdout so the caller knows exactly what was assumed and which flags to pass to override: ``` Using defaults for unprovided options: --eslint ESLint (use --biome for Biome, --no-eslint for None) --no-react-compiler No React Compiler (use --react-compiler for React Compiler) --agents-md AGENTS.md (use --no-agents-md for No AGENTS.md) --import-alias "@/*" To customize, re-run with explicit flags. ``` The `displayConfig` array is extended with a `flags` field so this output is auto-generated from the same source of truth used for the interactive prompts. Existing behavior for `--yes`, CI mode, and fully interactive mode (no flags) is unchanged.
