Instructions for AI coding agents working with this codebase.

Package Management

Always check the latest version before installing a package.

Before adding or updating any dependency, verify the current latest version on npm:

npm view <package-name> version

Or check multiple packages at once:

npm view ai version
npm view @ai-sdk/provider-utils version
npm view zod version

This ensures we don't install outdated versions that may have incompatible types or missing features.

Code Style

• Do not use emojis in code or UI
• Use shadcn CLI to add shadcn/ui components: pnpm dlx shadcn@latest add <component>

Dev Servers

All apps and examples with dev servers use portless to avoid hardcoded ports. Portless assigns random ports and exposes each app via .localhost URLs.

Naming convention:

• Main web app: json-render → json-render.localhost:1355
• Examples: [name]-demo.json-render → [name]-demo.json-render.localhost:1355

When adding a new example that runs a dev server, wrap its dev script with portless <name>:

{
  "scripts": {
    "dev": "portless my-example-demo.json-render next dev --turbopack"
  }
}

Do not add --port flags -- portless handles port assignment automatically. Do not add portless as a project dependency; it must be installed globally.

Workflow

• Run pnpm type-check after each turn to ensure type safety
• When making user-facing changes (new packages, API changes, new features, renamed exports, changed behavior), update the relevant documentation:
  • Package README.md files in packages/*/README.md
  • Root README.md (if packages table, install commands, or examples are affected)
  • Skills in skills/*/SKILL.md (if the package has a corresponding skill)
  • AGENTS.md (if workflow or conventions change)

Source Code Reference

Source code for dependencies is available in opensrc/ for deeper understanding of implementation details.

See opensrc/sources.json for the list of available packages and their versions.

Use this source code when you need to understand how a package works internally, not just its types/interface.

Fetching Additional Source Code

To fetch source code for a package or repository you need to understand, run:

npx opensrc <package>           # npm package (e.g., npx opensrc zod)
npx opensrc pypi:<package>      # Python package (e.g., npx opensrc pypi:requests)
npx opensrc crates:<package>    # Rust crate (e.g., npx opensrc crates:serde)
npx opensrc <owner>/<repo>      # GitHub repo (e.g., npx opensrc vercel/ai)
