Why build with AI coding agents?

AI coding agents are great at generating code, but they’re only as effective as the context you give them. In real SaaS codebases, agents need to understand:

  • project structure (where to put things)
  • architectural conventions (server vs client, API patterns, auth + billing flows)
  • how to run checks (linting, formatting, tests)
  • what “done” means (acceptance criteria, UX expectations)

Without that, you get inconsistent changes, wrong file placement, or “works on my machine” edits.


What is agents.md?

agents.md is a simple, agent-friendly file that describes how this repository works.

It’s designed to be readable by humans and consumable by coding agents so they can:

  • pick the right folders and patterns
  • follow the code style and conventions
  • run the correct commands before finishing
  • avoid risky changes (secrets, configs, infra)

supastarter includes agents.md as a single source of truth to support multiple popular coding agents in one place.


supastarter: a production-ready foundation for agent-driven SaaS coding

With supastarter you’re not starting from a blank repo. Your agent starts from a solid base that already includes the “hard parts”:

  • authentication and user flows
  • organizations / multi-tenancy
  • billing and subscriptions
  • emails, analytics, monitoring
  • background jobs and scheduled tasks
  • a modern UI system and customization docs

That means your AI agent can focus on building your product features instead of reinventing infrastructure.


Works with popular coding agents

Because agents.md is editor-agnostic, you can use the same repo instructions across tools like:

  • Cursor
  • Windsurf
  • GitHub Copilot
  • Claude Code

Recommended workflow

  1. Start with supastarter’s Next.js starter kit.
  2. Let your agent read agents.md first.
  3. Give the agent a scoped feature request (UI + API + tests).
  4. Have the agent run lint/tests before it finishes.

You’ll get more consistent diffs, fewer “mystery” changes, and faster iteration as your SaaS grows.
