What problem does it solve? When you finish building a major feature or hit a hard bug, you need deep architectural analysis rather than quick edits. This Skill delegates that work to a specialized architect subagent that reviews code, plans implementations, and performs root cause analysis without making changes itself. ## Core Features & Use Cases - Task Evaluation: Assess completed or ongoing work against stated goals using the evaluate_task responsibility. - Implementation Planning: Generate structured plans with task decomposition and sequencing for new features. - Root Cause Debugging: Analyze regressions with optional git diffs and commit ranges to pinpoint failures. - Use Case: After implementing rate limiting on your API, spawn the architect with the middleware and route files to verify the design, or pass a failing session validation function with the recent git diff to find the regression. ## Quick Start Ask the architect to review the authentication module files and evaluate whether the recent changes meet the original design goals.
