+    Load the `review-misses` skill, then open `$HOME/.config/coyote/share/review-misses.md` and find the newest `## MISS-` entry (just appended: "{{description}}"). Interview me briefly — one focused question at a time — to fill in the `<fill …>` fields, then write the completed entry back. Push hardest on the **detection pattern**: it must be a concrete check or grep a reviewer can run, not advice. If my miss matches an existing entry's defect class, propose sharpening that entry instead of keeping a duplicate.
