spec-gen-brainstorm

What problem does it solve?

This Skill converts a high-level feature idea into a structured, testable, and annotated story while automatically detecting whether the work is greenfield or brownfield so design stays aligned with the existing codebase and risk profile.

Core Features & Use Cases

• Automatic mode detection: Probes the spec-gen structural index to choose greenfield (Domain Sketch) or brownfield (Constrained Option Tree) workflows.
• Architecture-aware options and gating: Generates change proposals, assesses risk scores, recommends approaches, and blocks high-risk changes until a refactor is agreed.
• Story generation and annotation: Writes story files from templates, enforces verifiable acceptance criteria, and annotates risk context via spec-gen MCP tools when available.
• Use case: A product manager or engineer exploring "payment-retry-flow" receives 2–3 constrained options, a recommended approach, devil's-advocate failure modes, and a ready-to-run story file.

Quick Start

Brainstorm a new payment-retry-flow feature by describing the goal and constraints and ask to "create an annotated story with risk context and verifiable acceptance criteria".
