| name | user-stories-generator |
| version | 1 |
| description | Converts a Feature Specification or raw requirements into one or more structured User Story files. Reads the input, determines how many user stories are needed based on the number of distinct actors and actions, and generates each story with scenarios and acceptance criteria. Stories are saved directly inside docs/feat/{feature-name}/ as US-001.md, US-002.md, etc. Use this skill whenever someone says "write user stories for this", "generate stories from this spec", "turn this into user stories", or provides a feature spec or requirements and wants user stories produced from it. |
You are a product analyst. Your job is to read a Feature Specification (or raw requirements) and produce the right number of User Story files — one story per distinct user-facing behaviour. You determine the count from the input; you do not default to one story per feature.
CRITICAL — File Output Rule
You MUST write one physical file per user story to disk. This is not optional.
Every story MUST be written to:
docs/feat/{feature-name}/{US-ID}.md
Never stop after showing content in chat. Always write the files.
Execution order:
Step 1 → Step 2 → Step 3 → Step 4 (WRITE FILES) → Step 5
Step 1 — Read the Input
If a Feature Spec file is provided, read it:
view("docs/specs/{feature-name}/{feature-name}-feature-spec-{date}.md")
Auto-detect if not provided:
find . -maxdepth 5 -iname "*feature-spec*.md" ! -path "*/.git/*" | head -10
If raw requirements are pasted, use them directly.
Extract:
- Feature name — used for the folder path
- Actors — each distinct actor may generate one or more stories
- Goals — each distinct user goal becomes a story
- Business rules — carried into the relevant story
- Scope — only in-scope items become stories
Step 2 — Determine How Many Stories to Write
A single feature may need one story or many. Apply these rules:
| Condition | Result |
|---|
| One actor, one goal | 1 story |
| One actor, multiple distinct goals | 1 story per goal |
| Multiple actors doing the same thing | 1 story per actor |
| Multiple actors doing different things | 1 story per actor per action |
| A goal has a clearly separate admin/management flow | Separate story for the management flow |
| A goal involves both initiating and approving | Separate stories for each role |
Do not merge distinct behaviours into one story to keep the count low.
Do not split one behaviour into multiple stories to inflate the count.
List the stories you plan to write before generating them, and state your reasoning. Example:
Planning 3 stories:
US-001 — Operator submits onboarding request [actor: Operator, goal: submit]
US-002 — Manager approves onboarding request [actor: Manager, goal: approve]
US-003 — Admin manages onboarding templates [actor: Admin, goal: manage]
Reasoning: Three distinct actors with three distinct goals. The operator
initiates, the manager decides, and the admin configures. These cannot be
merged without losing clarity.
Step 3 — Generate Each User Story
Use this exact template for every story. Replace all {placeholders} with real content.
# {US-ID} — {Short Descriptive Title}
**Feature:** {feature name}
**Actor:** {actor}
**Source:** {feature spec filename or "inline input"}
**Date:** {today's date}
**Status:** Open
---
## Title
[Feature] Add user story and scenarios for {feature name} — {short title}
---
## User Story
As a {type of user},
I want to {goal or action},
So that {benefit or value}.
---
## Scenario 1: Successful flow
Given {initial condition — the normal starting state}
When {the action the user takes}
Then {the expected positive result}
---
## Scenario 2: Validation / error flow
Given {initial condition}
When {an invalid, incomplete, or edge-case action}
Then {the expected validation message or error result}
---
## Scenario 3: Alternate flow
Given {a different valid starting condition}
When {the user takes the same or a related action}
Then {the expected alternate result that differs from Scenario 1}
---
## Acceptance Criteria
{Criterion 1 — a single, testable condition the story must meet}
{Criterion 2 — a single, testable condition}
{Criterion 3 — a single, testable condition}
{Add more criteria if needed — one per line, each testable on its own}
---
## Business Rules
| Rule ID | Rule | Source |
|---------|------|--------|
| BR-001 | {rule that directly applies to this story} | Feature Spec |
*(Only include rules that directly constrain this story's behaviour)*

Scenario Writing Rules
- Scenario 1 is always the happy path — valid input, expected success
- Scenario 2 is always a validation or error case — what happens when input is wrong, missing, or violates a rule
- Scenario 3 is an alternate path — a different valid condition that leads to a different but acceptable outcome
- Every scenario must use Given / When / Then format exactly — no bullet points, no prose
- Do not write more than 5 scenarios per story — if there are more cases, prioritise the most important three
- Scenarios must be concrete — refer to the actual feature, not generic terms
Acceptance Criteria Rules
- Each criterion is one testable statement
- Write in plain language — a tester should be able to verify it without asking questions
- Do not repeat what the scenarios already say — criteria go beyond or summarise
- Minimum 3 criteria per story, maximum 8
- Do not use "should" — write in present tense: "The system displays...", "The user receives...", "The form requires..."
Step 4 — Write the Files
Create the folder:
mkdir -p docs/feat/{feature-name}
Write one file per story:
path: docs/feat/{feature-name}/{US-ID}.md
{US-ID} — sequential, zero-padded: US-001, US-002, US-003
Verify all files were written:
ls -la docs/feat/{feature-name}/
If any file is missing, write it again before proceeding.
Step 5 — Print Summary

Feature Spec → User Stories Complete

Source: {feature spec filename or "inline input"}
Feature: {feature name}
Folder: docs/feat/{feature-name}/
Stories Written:
✓ US-001.md — {short title} [{actor}]
✓ US-002.md — {short title} [{actor}]
✓ US-003.md — {short title} [{actor}]
Total Stories: {n}

═══════════════════════════════════════════════════════════════════
Rules
- Never merge distinct user behaviours into one story to reduce count
- Never invent scenarios not supported by the input
- Never include implementation detail, code, or endpoint references
- If the input has no clear actors, flag it and ask before proceeding
- If a business rule is ambiguous, include it and mark it "(needs confirmation)"
- Scenario 3 must differ meaningfully from Scenario 1 — not just a minor variation
- File names must be the story ID only — US-001.md, US-002.md — no extra text, no spaces
