What problem does it solve? Turning a rough feature idea into a concrete technical design is hard: assumptions go unstated, alternatives go unweighed, and decisions get lost. This Skill structures that process into a guided dialogue that ends with a written design doc. ## Core Features & Use Cases - Context Exploration: Reads existing project plans, findings, and code before asking questions, so it never asks what the codebase can answer. - Clarifying Dialogue: Asks questions one at a time, each with a recommended answer and alternatives, until the problem is crisply stated. - Approach Comparison: Proposes 2-3 implementation approaches with tradeoffs (cost, risk, blast radius, maintenance) plus a single clear recommendation. - Design Doc Output: Writes a dated design doc to docs/brainstorm/ with an Open questions section that feeds the next pipeline stage. - Use Case: You have a vague idea like "add caching to the API layer." Run the brainstorm to explore the codebase, clarify scope, compare caching strategies, and get a design doc ready for stress-testing. ## Quick Start Ask the AI to brainstorm a design for the feature you are about to build, for example by saying "brainstorm how to add rate limiting to our API endpoints."
