Define Use Case

Category: General  ·  Sub-category: general-misc  ·  Last updated:
Capture a single use case for a target project. Collects a free-form description from the user, produces a formalized version (summary, acceptance criteria, pitfalls), runs a clarifying-question loop, and saves the result as an incrementally-numbered Markdown file in the target project's `use-cases/` folder. After saving, offers to define another use case or continue to implementation via the `develop` skill. Use when the user wants to document what the project should do, before or instead of jumping into implementation.

From the source SKILL.md

Entry point for adding a single use case to a target project. The skill is deterministic: one use case per invocation, no batching. Run it again to add another.

What this skill does

Define Use Case is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/define-use-case/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user wants to document what the project should do, before or instead of jumping into implementation.

Who uses this skill

It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
