Produces a complete, ready-to-groom user story following the standard Atlassian/agile format. It applies the INVEST criteria and the 3 Cs framework (Card, Conversation, Confirmation) to ensure each story is well-scoped, valuable, and testable — not just syntactically correct.
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
## What this skill does
Produces a complete, ready-to-groom user story following the standard Atlassian/agile format. It applies the INVEST criteria and the 3 Cs framework (Card, Conversation, Confirmation) to ensure each story is well-scoped, valuable, and testable — not just syntactically correct.
**Reference:** Atlassian — [User stories with examples and a template](https://www.atlassian.com/agile/project-management/user-stories)
## When to use it
- User asks to "write a user story" or "create a story" for a feature or requirement.
- User wants to refine a rough idea, acceptance note, or bug description into a proper story.
- User needs to validate whether an existing story is well-formed.
- User is decomposing an epic into individual stories.
## Key concepts
### The standard format (Connextra template)
```
As a [persona],
I want to [action / capability],
so that [benefit / outcome].
```
- **Persona** — who benefits (not "user" generically — use a real role: "logged-in customer", "warehouse operator", "admin").
- **Want** — the capability or action, not the implementation ("I want to filter results" not "I want a dropdown").

How to install
mdr add marielynneblock/arcanum-artifex/write-user-story@sha256:e7daea96754d0300The line at the top of this page pins the label v1.0.0, 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.
