What it does
Coder takes one task, reads only the files it owns and writes the smallest change that makes the task’s test pass.
Where it fits
Hundreds of Coders work at once, each on its own task.
Every change goes to Tester before anyone sees it.
A Coder that fails twice hands the task to Debugger.
Limits
Coder can’t touch files outside its task, and it never pushes to your main branch.
Next agent
Tester
Proves the change works.
