Write structured use cases with main and alternate flows. Use when the user says "write a use case", "document the user flow", "use case diagram", "actor goal list", "main success scenario", "fully dressed use case", "what does the user do step by step", "system behavior for this feature", "interaction flow" - even if they don't explicitly say "use case".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Reference Files - `references/use-case-template.md` - Cockburn's Fully Dressed Use Case template with field descriptions and a worked example. Read this in Step 3 when writing individual use cases. ## Overview Based on **Writing Effective Use Cases** by Alistair Cockburn - the definitive reference on use case methodology. Cockburn's key insight is the goal level altitude metaphor: most use cases should be written at "sea level" (one user, one sitting, one goal). Writing too high (kite/cloud) produces vague summaries; too low (fish/clam) produces implementation detail disguised as requirements. The Actor-Goal List is the starting point, not the use case itself. ## Workflow ### Step 1: Build the Actor-Goal List Before writing any use case, list every actor and their goals: ``` | Actor | Goal | Level | |-------|------|-------| | Customer | Place an order | Sea level (user goal) | | Customer | Track shipment | Sea level | | Warehouse clerk | Pick and pack order | Sea level | | System (scheduler) | Generate daily reports | Sea level | | Finance manager | Review quarterly revenue | Kite (summary) | ``` This list is the master index. Every sea-level goal becomes one use case. …

How to install
mdr add qa-aman/claude-skills/use-case-writer@sha256:9cf196c06b5bc6baThe line at the top of this page pins the label git:20260323.771ca1c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
