Best for engineers who want to design and build professional agent
applications.

## Shared starting points

* [Environment Setup](/reading-paths/environment-setup): the shared local setup guide for
  running starter-code checks before deeper implementation work.
* [Sample Projects](/reading-paths/sample-projects): the public guide to current example
  starters and where they live in the repo.

## What this path optimizes for

* Reusable implementation patterns
* Production-minded system design
* Concrete examples that connect ideas to real builds
* Comparative awareness of tools and platforms
