Crear un Skill

Skills are structured instructions that guide your AI assistant through repeatable workflows. Each skill is a SKILL.md file with YAML frontmatter and markdown sections.

Skill Structure

A skill lives in its own directory under .claude/skills/ (project-level) or is distributed from src/rai_cli/skills_base/ (framework-level).

.claude/skills/
  my-custom-skill/
    SKILL.md

Required Frontmatter

Every SKILL.md starts with YAML frontmatter:

---
name: rai-my-skill
description: >
  One-paragraph description of what this skill does and when to use it.

license: MIT

metadata:
  raise.work_cycle: utility       # utility | epic | story | session
  raise.frequency: as-needed      # always | as-needed | once
  raise.fase: "0"                 # ShuHaRi phase
  raise.prerequisites: ""         # Required prior skills
  raise.next: ""                  # Suggested next skill
  raise.gate: ""                  # Gate to check before running
  raise.adaptable: "true"         # Can be customized per project
  raise.version: "2.2.3"          # Framework version
  raise.visibility: public        # public | private
---

Required Sections

After frontmatter, include these markdown sections:

  1. Purpose — What the skill does and why it exists
  2. Context — When to use, when to skip, inputs needed, time boxing
  3. Steps — Numbered steps with <verification> blocks after each
  4. Output — What artifacts the skill produces
  5. Quality Checklist — Verification criteria as a checkbox list

Verification Blocks

Each step should end with a verification gate:

### Step 1: Do the Thing

Instructions for this step.

<verification>
Expected outcome that confirms step completion.
</verification>

<if-blocked>
What to do if this step fails.
</if-blocked>

Naming Conventions

Skill names follow {domain}-{action} pattern: - rai-story-start — story domain, start action - rai-debug — utility domain, single action - rai-discover-scan — discovery domain, scan action

Validate a name before creating:

rai skill check-name my-skill-name

Scaffold a Skill

Use the CLI to generate the skeleton:

rai skill scaffold my-custom-skill

This creates the directory and a SKILL.md template with all required sections.

Skill Sets

Skill sets let teams customize which skills are active:

# List available skill sets
rai skill set list

# Create a custom set
rai skill set create my-team-set

# Compare sets
rai skill set diff default my-team-set

Validate

Check that your skill meets structural requirements:

rai skill validate my-custom-skill

This verifies frontmatter fields, required sections, and naming conventions.
