Create Prove It

You are about to give this repo a skill that makes every future agent prove its work in the running app, instead of saying "done" because the code looks right or the tests pass.

The output is a project-local skill, read cold by a future agent in the middle of some other task. Write it for that reader: exact commands, real selectors, no placeholders, nothing it has to work out.

The steps, in order:

0. Ask: the app, or a migration?
1. Map the surfaces
2. Check you can reach them
3. Find the answer keys
4. Brainstorm methods, then let the user pick
5. Generate the skill
6. Run it once for real
7. Hand over

Don't skip step 6. A verification skill nobody has run is a guess.
