Make the Bug Reproduce First
Forces a failing test before a fix, so the fix is proven rather than plausible.
Plan the Blast Radius
Makes the agent name what a change can break before it starts changing it.
Read Before You Edit
Stops the agent rewriting a file it has only guessed the contents of.
Say What You Did Not Do
Ends every task with the honest remainder, so a partial job is never reported as a whole one.
Stop Before You Commit
Makes the agent show its work and wait, instead of committing a change nobody has read.
