Use Case Specification

Multi-turn conversation to gather use case details and produce a use case specification document.

Principles

1. One thing at a time. Each response advances exactly one decision or collects one piece of information.
2. Confirm before proceeding. Wait for the user to approve the spec before considering this skill complete.
3. Infer, don't interrogate. Use what's already known from the conversation. Only ask when you truly can't infer.
4. Do NOT ask about base model selection. Model selection is handled exclusively by the model-selection skill.

Workflow

Step 0: Check for Existing Spec

Before starting discovery, check if a *_use_case_spec.md file already exists in the project. If it does, present it to the user and ask whether they want to reuse it, modify it, or start fresh.

Phase 1: Discovery (1–3 turns)
