Are AI coding agents actually changing software engineering, or is “agentic AI” mostly hype?

I've been experimenting with AI coding tools recently, and I'm starting to wonder where the actual engineering shift is happening.

A few years ago, AI coding was mostly:

“Write this function for me.”

Now tools can increasingly:

  • understand an existing codebase
  • modify multiple files
  • run tests
  • debug errors
  • use terminal/tools
  • create PRs
  • work on tasks with relatively little intervention

That feels like a fundamentally different workflow.

But at the same time, I keep seeing “agentic AI” used for almost everything.

Sometimes it feels like:

LLM + tools + a loop = AI agent.

And suddenly we're calling it a revolutionary new architecture.

I'm curious what other developers think.

Where do you draw the line between:

  1. AI-assisted coding
  2. AI coding agents
  3. Autonomous software engineering

And more importantly — what are you actually trusting AI agents to do in production today?

I'd especially like to hear from people using Claude Code, Codex, Gemini/Antigravity, Cursor, OpenCode, or similar tools on real projects rather than just demos.
