guidelines

project coding guidelines input validation, error handling, DDD structure, type safety, testing, gRPC, Rust, linting, and more. Invoke when writing, reviewing, or planning code — including setting up a backend, API, service, or any new project.

Set up an opinionated TypeScript Node.js project in the current directory or a new named directory. Uses pnpm via corepack, strict tsconfig, eslint-config-agent, Prettier, Vitest, and git hooks. Use when initializing any Node.js service, CLI, or library — not Next.js (use new-project-nextjs for that).

Set up an opinionated Rust project in the current directory or a new named directory. Configures Cargo with common deps via cargo add, rustfmt, clippy, rust-toolchain, and git hooks. Use when initializing any Rust binary, library, or service.
