Design and run combined live test cases for a read. A read signed out runs a wide, varied first batch of about 10 to 20; a signed-in read runs four inputs at most. A write skips this skill and proves its tool with one run.
Read before building any tool that reads, adds to, changes or checks out a cart: when to sign in or use a guest cart or checkout, read the cart before and after, quantity, account values and site limits.
Do a write build's requested task once as a live act session, confirm it, then compose and publish its script without running it again.
Discover an evidenced login entry and sign in screen by screen with verified host autofill.
Validate the caller's input, refuse a bad value or fail on one the page did not apply with the right error, and ask the run's caller mid-run for what only they know, such as a choice only the page offers or a code the site sends.
Guarded native/custom selection, dynamic choices and consequential form completion.
Kernel script operation SDK, mint intake, execution targets and ownership.
What publication checks, which private values never go into published files, and how to act on each rejection.
