Use Case Specification
Multi-turn conversation to gather use case details and produce a use case specification document.
Principles
- One thing at a time. Each response advances exactly one decision or collects one piece of information.
- Confirm before proceeding. Wait for the user to approve the spec before considering this skill complete.
- Infer, don't interrogate. Use what's already known from the conversation. Only ask when you truly can't infer.
- Do NOT ask about base model selection. Model selection is handled exclusively by the model-selection reference.
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.
Step 1: Determine Intent
Check the plan (PLAN.md) or conversation context to determine whether the user wants to:
- Fine-tune a model → read
references/spec-for-finetuning.mdand follow it. - Deploy a base model → read
references/spec-for-deployment.mdand follow it.
If the intent is already clear from the plan (e.g., the plan includes finetuning steps vs. only model-selection + model-deployment), use that. If ambiguous and not already resolved by the planning skill, ask:
"Are you looking to fine-tune a model for your use case, or deploy a base model as-is?"
⏸ Wait for user response.
Edit Protocol
- If the user requests changes pertaining to any information covered by use_case_spec.md, you must edit it accordingly and ask for confirmation again.
- The user can edit use_case_spec.md directly if they want to. If the user says they've updated the file directly, read it to get the latest in your context.
