User Story Creator

Overview

Convert session context into well-structured User Stories (Historias de Usuario). After completing development activities, use this skill to synthesize work into a formal narrative that:

• Summarizes high-level benefits (who, what, why)
• Groups changes into logical, atomic subtasks
• Documents technical actions in future tense
• Includes acceptance criteria and technical validation

Key principle: The story documents "what will be done" not "what was done" — written in future tense as if planning the implementation.

When to Use This Skill

• After resolving one or more issues and want to document as a formal User Story
• When you've completed features, bug fixes, or refactoring and need to synthesize the narrative
• When you need to group technical changes (file modifications, API updates, schema changes) into logical subtasks
• To create audit-ready documentation for stakeholders unfamiliar with implementation details

Not automatic: Always request explicitly or confirm when suggested. Never generate unsolicited.

Workflow

1. Provide Context

When you request the skill, give me:

• Summary of what was completed (or I'll infer from conversation history)
• Key modules/files affected (optional — I can analyze from git context)
• The main goal or benefit delivered

2. I Generate the Structure

I will:

1. Extract commit labels from your recent commits (feat, fix, refactor, etc.)
2. Group changes logically using these heuristics:
   • <12 files/changes → One subtask per logical grouping (module-based, component-based)
   • ≥12 files/changes → Group by module, feature area, or architectural layer (avoid both overly generic and overly specific)
3. Auto-generate title with "HU - " prefix
4. Create subtasks with appropriate prefix (Feature:, Fix:, Refactor:, etc.)
5. Propose acceptance criteria based on changes made

3. Review & Approve

I'll present the story in plain text format (easy to copy) and ask for approval before finalizing.

Output Format

See references/template.md for the exact structure.

Key characteristics:

• Historia de Usuario header with descriptive title
• Cómo/Quiero/Para format (always "Cómo: Desarrollador")
• Subtareas with prefixes: Feature:, Fix:, Refactor:, Chore:, Docs:, Test:, Perf:, Style:, Build:, CI:, Env:
• Future tense throughout (Implementar, Refactorizar, Validar, etc.)
• Descripción for each subtask (1-2 lines explaining the "why" and scope)
• Acciones a Realizar (atomic, concrete actions—2-5 bullets per subtask)
• Criterios de Aceptación (system behavior verification, regression prevention)

Grouping Logic

See references/grouping-guide.md for detailed heuristics.

Quick rules:

• Related changes → same subtask (e.g., model update + schema update for one feature)
• Module-based grouping when many changes across multiple modules
• Independent changes → separate subtasks
• Balance: Aim for 3-8 subtasks per story (fewer if simple, more only if substantially complex)

Commit Label Mapping

See references/commit-labels.md for how commit messages map to subtask prefixes.

Common mappings:

• feat: → Feature:
• fix: → Fix:
• refactor: → Refactor:
• test: → Test:
• docs: → Docs:

Example

See references/examples.md for 2-3 realistic examples from actual development sessions.
