What problem does it solve? HarmonyOS code changes can pass static checks yet still contain logic errors, state management mistakes, resource leaks, and security issues that machines cannot catch. This Skill provides a structured review workflow that gates delivery quality before build and UI verification. ## Core Features & Use Cases - Machine-check-first workflow: Runs dcli__lsp_check and dcli__check_lint to zero diagnostics before any manual review begins. - Nine-dimension review checklist: Covers requirement coverage, logic correctness, state management (V1/V2 decorators), performance, lifecycle resources, error handling, security/permissions, engineering conventions, and maintainability. - Graded review reports: Produces P0 (blocking), P1 (must fix), and P2 (suggestion) findings with file locations and fix recommendations, plus mandatory re-verification after fixes. - Independent subagent review: Dispatches fresh-context subagents for complex features to eliminate blind spots from long development sessions. - Use Case: After implementing a new ArkTS page with state management, run this review to catch @Watch infinite loops, missing aboutToDisappear cleanup, and hardcoded strings before UI verification. ## Quick Start Review my recent HarmonyOS changes against the feature contract and produce a P0/P1/P2 code review report.
