Why would anyone build with this?

REASON 1

Test how an AI coding assistant would handle a task before letting it touch your real repo.

REASON 2

See exactly what files or GitHub issues an agent would create using the fake GitHub interface.

REASON 3

Compare how an agent behaves across different profiles, like Mac versus Linux setups.

REASON 4

Review a saved record of everything an agent attempted so you can refine your automation approach.
