When Creating Skill Template Use Skill Builder

Skill Builder - Claude Code Skill Template Generator

Overview

Creates new Claude Code Skills with proper structure, YAML frontmatter, progressive disclosure, and complete documentation. Ensures skills follow best practices and specification requirements.

When to Use

• Creating new reusable skills
• Need skill template/boilerplate
• Building skill library
• Standardizing skill format

Phase 1: Design Skill Structure (5 min)

Objective

Define skill components and metadata

Agent: Base-Template-Generator

Step 1.1: Gather Requirements

const skillRequirements = {
  name: 'when-[condition]-use-[skill-name]',
  category: 'utilities|development|testing|machine-learning',
  description: 'Clear one-sentence purpose',
  agents: ['agent1', 'agent2'],
  phases: [
    { name: 'Phase 1', duration: '5min', objective: '...' },
    // ...
  ],
  triggers: ['When X happens', 'When Y is needed'],
  outputs: ['file1.json', 'report.md']
};

await memory.store('skill-builder/requirements', skillRequirements);

Step 1.2: Define YAML Frontmatter

---
name: when-[trigger]-use-[skill-name]
version: 1.0.0
description: Single sentence describing purpose
category: utilities
tags: [tag1, tag2, tag3]
agents: [agent1, agent2]
difficulty: beginner|intermediate|advanced
estimated_duration: 15-30min
success_criteria:
  - Criterion 1
  - Criterion 2
validation_method: test_type
dependencies:
  - claude-flow@alpha
  - other-dependency
prerequisites:
  - Required condition 1
outputs:
  - output-file-1
  - output-file-2
triggers:
  - Trigger condition 1
  - Trigger condition 2
---

Step 1.3: Plan Phase Structure

const phaseStructure = skillRequirements.phases.map((phase, i) => ({
  number: i + 1,
  title: phase.name,
  objective: phase.objective,
  duration: phase.duration,
  agent: phase.agent,
  steps: phase.steps,
  validation: phase.validation,
  memoryPattern: phase.memoryPattern,
  scriptTemplate: phase.scriptTemplate
}));

await memory.store('skill-builder/phase-structure', phaseStructure);

Validation Criteria

• Name follows convention
• All metadata defined
• Phases planned
• Agents identified

Phase 2: Generate Template (5 min)

Objective

Create skill file structure and boilerplate

Agent: Base-Template-Generator

Step 2.1: Create SKILL.md

---
[YAML frontmatter from Phase 1]
---

## Purpose
${purpose}

## When to Use
${triggers}

## Quick Start
\`\`\`bash
npx claude-flow@alpha skill-run ${skillName}
\`\`\`

## ${phases.length}-Phase Process
${phases.map((p, i) => `${i+1}. **${p.title}** (${p.duration}) - ${p.objective}`).join('\n')}

## Expected Output
${outputExample}

## Success Criteria
${successCriteria}

For detailed documentation, see SKILL.md

Step 2.3: Create PROCESS.md

# ${skillName} - Detailed Workflow

## Process Overview
${processOverview}

## Phase Breakdown
${phases.map(phase => `
### Phase ${phase.number}: ${phase.title}

**Objective**: ${phase.objective}
**Agent**: ${phase.agent}
**Duration**: ${phase.duration}

**Steps**:
${phase.steps.map((step, i) => `${i+1}. ${step}`).join('\n')}

**Outputs**: ${phase.outputs.join(', ')}
**Validation**: ${phase.validation}
`).join('\n---\n')}

## Workflow Diagram
[See process-diagram.gv]

## Integration Patterns
${integrationExamples}

Step 2.4: Create process-diagram.gv

digraph ${SkillName} {
    rankdir=TB;
    node [shape=box, style=filled, fillcolor=lightblue];

    start [label="Input", shape=ellipse, fillcolor=lightgreen];
    ${phases.map((p, i) => `
    phase${i+1} [label="Phase ${i+1}: ${p.title}\\n(${p.duration})\\nAgent: ${p.agent}", fillcolor=lightcoral];
    output${i+1} [label="${p.outputs.join('\\n')}", shape=parallelogram];
    `).join('\n')}
    end [label="Output", shape=ellipse, fillcolor=lightgreen];

    start -> phase1;
    ${phases.map((p, i) => `
    phase${i+1} -> output${i+1};
    output${i+1} -> phase${i+2 <= phases.length ? i+2 : 'end'};
    `).join('\n')}
}

Phase 3: Implement Functionality (8 min)

Objective

Add implementation details and code examples

Agent: Coder

Step 3.1: Add Code Examples

// For each phase, add:
// - Implementation code snippets
// - Memory operations
// - Hook integrations
// - Script templates

const phaseImplementation = {
  codeExample: `
async function execute${phase.title}() {
  // Implementation

      ...phases.reduce((acc, phase) => ({
        ...acc,
        [phase.key]: { /* phase data */ }
      }), {})
    }
  }
};

Step 3.3: Add Integration Examples

// How to use with other skills
const integrationExamples = {

  filesCreated: [
    'SKILL.md',
    'README.md',
    'PROCESS.md',
    'process-diagram.gv'
  ],
  linesOfCode: calculateLOC(),
  estimatedDuration: skillRequirements.estimatedDuration,
  agentsRequired: skillRequirements.agents.length,
  phasesImplemented: phases.length,
  validationStatus: 'PASSED',
  readyForUse: true

Memory Schema

{
  "skill-builder/": {
    "session-${id}/": {
      "requirements": {},
      "phase-structure": [],
      "generated-files": [],
      "validation-results": {},
      "completion": {}
    }
  }
}

Common Patterns

Quick Skill Template

npx claude-flow@alpha skill-run skill-builder \
  --name "my-new-skill" \
  --category "utilities" \
  --agents "coder,tester" \
  --phases "3"

From Existing Workflow

# Convert workflow to skill
npx claude-flow@alpha skill-builder \
  --from-workflow "workflow.json" \
  --output-dir ".claude/skills/utilities/"

Skill Completion

Outputs:

1. SKILL.md: Complete skill specification
2. README.md: Quick start guide
3. PROCESS.md: Detailed workflow
4. process-diagram.gv: Visual process diagram

Skill complete when all files created and validation passes.
