Skill Builder

What This Skill Does

Creates production-ready Claude Code Skills with proper YAML frontmatter, progressive disclosure architecture, and complete file/folder structure. This skill guides you through building skills that Claude can autonomously discover and use across all surfaces (Claude.ai, Claude Code, SDK, API).

Prerequisites

• Claude Code 2.0+ or Claude.ai with Skills support
• Basic understanding of Markdown and YAML
• Text editor or IDE

Quick Start

Creating Your First Skill

# 1. Create skill directory (MUST be at top level, NOT in subdirectories!)
mkdir -p ~/.claude/skills/my-first-skill

# 2. Create SKILL.md with proper format
cat > ~/.claude/skills/my-first-skill/SKILL.md << 'EOF'
---
name: "My First Skill"
description: "Brief description of what this skill does and when Claude should use it. Maximum 1024 characters."
---

# My First Skill

## What This Skill Does
[Your instructions here]

## Quick Start
[Basic usage]
EOF

# 3. Verify skill is detected
# Restart Claude Code or refresh Claude.ai

Complete Specification

📋 YAML Frontmatter (REQUIRED)

Every SKILL.md must start with YAML frontmatter containing exactly two required fields:

---
name: "Skill Name"                    # REQUIRED: Max 64 chars
description: "What this skill does    # REQUIRED: Max 1024 chars
and when Claude should use it."       # Include BOTH what & when
---

Field Requirements

name (REQUIRED):

• Type: String
• Max Length: 64 characters
• Format: Human-friendly display name
• Usage: Shown in skill lists, UI, and loaded into Claude's system prompt
• Best Practice: Use Title Case, be concise and descriptive
• Examples:

- ✅ "API Documentation Generator" - ✅ "React Component Builder" - ✅ "Database Schema Designer" - ❌ "skill-1" (not descriptive) - ❌ "This is a very long skill name that exceeds sixty-four characters" (too long)

description (REQUIRED):

• Type: String
• Max Length: 1024 characters
• Format: Plain text or minimal markdown
• Content: MUST include:

1. What the skill does (functionality) 2. When Claude should invoke it (trigger conditions)

• Usage: Loaded into Claude's system prompt for autonomous matching
• Best Practice: Front-load key trigger words, be specific about use cases
• Examples:

- ✅ "Generate OpenAPI 3.0 documentation from Express.js routes. Use when creating API docs, documenting endpoints, or building API specifications." - ✅ "Create React functional components with TypeScript, hooks, and tests. Use when scaffolding new components or converting class components." - ❌ "A comprehensive guide to API documentation" (no "when" clause) - ❌ "Documentation tool" (too vague)

YAML Formatting Rules

---
# ✅ CORRECT: Simple string
name: "API Builder"
description: "Creates REST APIs with Express and TypeScript."

# ✅ CORRECT: Multi-line description
name: "Full-Stack Generator"
description: "Generates full-stack applications with React frontend and Node.js backend. Use when starting new projects or scaffolding applications."

# ✅ CORRECT: Special characters quoted
name: "JSON:API Builder"
description: "Creates JSON:API compliant endpoints: pagination, filtering, relationships."

# ❌ WRONG: Missing quotes with special chars
name: API:Builder  # YAML parse error!

# ❌ WRONG: Extra fields (ignored but discouraged)
name: "My Skill"
description: "My description"
version: "1.0.0"       # NOT part of spec
author: "Me"           # NOT part of spec
tags: ["dev", "api"]   # NOT part of spec
---

Critical: Only name and description are used by Claude. Additional fields are ignored.

📂 Directory Structure

Minimal Skill (Required)

~/.claude/skills/                    # Personal skills location
└── my-skill/                        # Skill directory (MUST be at top level!)
    └── SKILL.md                     # REQUIRED: Main skill file

IMPORTANT: Skills MUST be directly under ~/.claude/skills/[skill-name]/. Claude Code does NOT support nested subdirectories or namespaces!

Full-Featured Skill (Recommended)

~/.claude/skills/
└── my-skill/                        # Top-level skill directory
        ├── SKILL.md                 # REQUIRED: Main skill file

• Scope: Available only in this project
• Version Control: SHOULD be committed to git
• Use Case: Team workflows, project-specific tools, shared knowledge

🎯 Progressive Disclosure Architecture

Claude Code uses a 3-level progressive disclosure system to scale to 100+ skills without context penalty:

Level 1: Metadata (Name + Description)

Loaded: At Claude Code startup, always Size: ~200 chars per skill Purpose: Enable autonomous skill matching Context: Loaded into system prompt for ALL skills

---
name: "API Builder"                   # 11 chars
description: "Creates REST APIs..."   # ~50 chars
---
# Total: ~61 chars per skill
# 100 skills = ~6KB context (minimal!)

Level 2: SKILL.md Body

Loaded: When skill is triggered/matched Size: ~1-10KB typically Purpose: Main instructions and procedures Context: Only loaded for ACTIVE skills

# API Builder

## What This Skill Does
[Main instructions - loaded only when skill is active]

## Quick Start
[Basic procedures]

## Step-by-Step Guide
[Detailed instructions]

Level 3+: Referenced Files

Loaded: On-demand as Claude navigates Size: Variable (KB to MB) Purpose: Deep reference, examples, schemas Context: Loaded only when Claude accesses specific files

# In SKILL.md
See [Advanced Configuration](docs/ADVANCED.md) for complex scenarios.
See [API Reference](docs/API_REFERENCE.md) for complete documentation.
Use template: `resources/templates/api-template.js`

# Claude will load these files ONLY if needed

Benefit: Install 100+ skills with ~6KB context. Only active skill content (1-10KB) enters context.

🎨 Content Best Practices

Writing Effective Descriptions

Front-Load Keywords:

# ✅ GOOD: Keywords first
description: "Generate TypeScript interfaces from JSON schema. Use when converting schemas, creating types, or building API clients."

# ❌ BAD: Keywords buried
description: "This skill helps developers who need to work with JSON schemas by providing a way to generate TypeScript interfaces."

Include Trigger Conditions:

# ✅ GOOD: Clear "when" clause
description: "Debug React performance issues using Chrome DevTools. Use when components re-render unnecessarily, investigating slow updates, or optimizing bundle size."

# ❌ BAD: No trigger conditions
description: "Helps with React performance debugging."

Be Specific:

# ✅ GOOD: Specific technologies
description: "Create Express.js REST endpoints with Joi validation, Swagger docs, and Jest tests. Use when building new APIs or adding endpoints."

# ❌ BAD: Too generic
description: "Build API endpoints with proper validation and testing."

🛠️ Adding Scripts and Resources

Scripts Directory

Purpose: Executable scripts that Claude can run Location: scripts/ in skill directory Usage: Referenced from SKILL.md

Example:

# In skill directory
scripts/
├── setup.sh          # Initialization script
├── validate.js       # Validation logic
├── generate.py       # Code generation
└── deploy.sh         # Deployment script

Reference from SKILL.md:

## Setup
Run the setup script:

./scripts/setup.sh

## Validation

Validate your configuration:

node scripts/validate.js config.json

Resources Directory

Purpose: Templates, examples, schemas, static files Location: resources/ in skill directory Usage: Referenced or copied by scripts

Example:

resources/
├── templates/
│   ├── component.tsx.template
│   ├── test.spec.ts.template
│   └── story.stories.tsx.template
├── examples/
│   ├── basic-example/
│   ├── advanced-example/
│   └── integration-example/
└── schemas/
    ├── config.schema.json
    └── output.schema.json

Reference from SKILL.md:

## Templates
Use the component template:

cp resources/templates/component.tsx.template src/components/MyComponent.tsx

## Examples

See working examples in `resources/examples/`:

- `basic-example/` - Simple component
- `advanced-example/` - With hooks and context

🔗 File References and Navigation

Claude can navigate to referenced files automatically. Use these patterns:

Markdown Links

See [Advanced Configuration](docs/ADVANCED.md) for complex scenarios.
See [Troubleshooting Guide](docs/TROUBLESHOOTING.md) if you encounter errors.

Relative File Paths

Use the template located at `resources/templates/api-template.js`
See examples in `resources/examples/basic-usage/`

Inline File Content

## Example Configuration
See `resources/examples/config.json`:

{ "option": "value" }

Best Practice: Keep SKILL.md lean (~2-5KB). Move lengthy content to separate files and reference them. Claude will load only what's needed.
