Individual skill

fix

Fix a defect the way a team reviewer will accept: capture the failure verbatim, prove the cause before changing a line, check that the current behaviour is not a decision somebody made on purpose, make the smallest change that removes the cause, verify it by layer, stop after three ruled-out hypotheses with a named person rather than guessing, call the team review on its own change and fix what it blocks on, and write the report that shows what was checked and what was not. Use for a bug report, a failing test, a broken endpoint or screen, or an investigation that has to end in an explanation rather than a guess; with --findings, to go through an atk:review's findings with their author, answer each, and fix the chosen ones on the pull request's branch. Triggers on: "fix bug", "debug", "bug", "go through the review findings", "sửa bug", "điều tra lỗi", "tìm nguyên nhân", "lỗi này", "xử lý từng finding của review", "バグ修正", "不具合調査", "原因調査", "レビュー指摘に対応", "/atk:fix".

# Fix a Defect (`atk:fix`)

Proves the cause, then fixes it. In that order, because a change made before the cause is proven is
a guess with a diff attached, and the review that catches it costs more than the investigation would
have.

The other half of the skill is where it stops, and it stops for two different reasons. When the
behaviour being called a bug turns out to be a decision somebody recorded, this skill does not fix
it; it brings the decision back to the person who owns it. And when three hypotheses have been ruled
out and none of them proved the cause, it hands the investigation over by name rather than carrying
on, because what is left at that point is usually somebody's knowledge rather than another search.
