-description: Use for Kimi Code code review and test write/review guidance. Groups the review and testing lenses used in this repo — `slop` (single-level-of-abstraction / layered error-handling review, invoked only on explicit request) and `test` (contract-driven per-test rules for both authoring and reviewing tests). Apply the sub-skill that matches the task; do not apply `slop` unprompted.
