What problem does it solve? Design documents often converge on the first obvious approach, skip tradeoff analysis, and drift from the approved proposal or spec. This Skill enforces a structured five-phase workflow that explores alternatives, secures user approval per section, and validates the final design.md against the proposal and spec before completion. ## Core Features & Use Cases - Phased Design Workflow: Runs schema resolution, approach exploration, direction selection, incremental section building, and generation in a fixed order with no skipping. - Tradeoff-Driven Exploration: Generates two or three meaningfully different design approaches with advantages, disadvantages, complexity, and a recommendation, then lets the user select the direction. - Mandatory Compliance Review: Dispatches a single-shot reviewer subagent that checks proposal alignment, spec alignment, scope drift, template compliance, YAGNI, and placeholders before the design is finalized. - Use Case: When running /opsx-new or /opsx-continue on an OpenSpec change, the skill walks you through architecture, components, data flow, error handling, and testing concerns one at a time, then writes a design.md that traces back to the approved proposal. ## Quick Start Ask the assistant to start the OpenSpec design phase for your change and follow the phase-by-phase approval prompts until design.md is written.
