What problem does it solve? When a new task or bug fix request arrives, it is easy to apply a local patch and miss the bigger picture. This Skill performs structural root cause analysis and multi-angle impact analysis before decomposing work into well-ordered, labeled tasks recorded in the project's task management file. ## Core Features & Use Cases - Structural Root Cause Analysis: Determines whether a problem is structural, prioritizes deterministic automated preventions (type system, lint rules, CI) over manual checklists, and traces bug origins via git history. - Multi-Dimensional Impact Analysis: Covers code, design, quality (tests, Storybook, a11y), design-file cross-checking for UI tasks, and meta-strategy impacts. - Task Decomposition & Recording: Breaks work into one-commit units labeled [設計], [型], [ロジック], [UI], [テスト], [story], [a11y], [メタ], [QA], orders them by dependency, and inserts them as unstarted items into the task list. - Use Case: A bug report arrives for a missing field in a form. The skill investigates why the bug was embedded, generates recurrence-prevention tasks (exhaustive checks, custom lint rules, CLAUDE.md updates), and registers the full task breakdown without writing any implementation code. ## Quick Start Ask the AI to insert a new task describing the change or bug you want planned, and it will analyze impacts and register decomposed tasks in the project task list.
