Skill Builder

Skill Builder

Create Claude Code skills following proven patterns from mature skills (Linear, Governance).

Templates: templates/ Best Practices: BEST-PRACTICES.md GitHub Automation: scripts/create-repo.mjs

Quick Start

When user asks to create a skill:

1. Gather Basic Info

Ask the user:

• Skill name: Short, descriptive (e.g., "governance", "linear", "docker")
• Description: One sentence explaining when to use it
• Trigger phrases: What should activate this skill?
• Problem it solves: What does the user gain?

2. Provide Templates

Copy and customize these templates:

# Copy all templates to working directory
cp -r templates/* /path/to/new-skill/

3. Customize Files

Guide user through customizing:

1. skills/<name>/SKILL.md — Core skill definition
2. CHANGELOG.md — Version history
3. README.md — Installation and usage
4. package.json — Plugin metadata and topics

4. Publish to GitHub

Run the automation script:

node skills/skill-builder/scripts/create-repo.mjs \
  --name "<skill-name>-claude-skill" \
  --description "Claude Code skill for <purpose>" \
  --topics "claude,claude-code,claude-plugin,<domain-topics>"

Template-First Workflow

Step 1: Create Directory Structure

mkdir -p <skill-name>-claude-skill/skills/<skill-name>/scripts
mkdir -p <skill-name>-claude-skill/templates  # Optional

Step 2: Copy Core Templates

Step 3: Fill In Placeholders

All templates use these placeholders:

Curated Best Practices

From Linear Skill (Most Mature)

From Governance Skill

Universal Patterns

SKILL.md Structure

Every SKILL.md should have:

---
name: <skill-name>
description: <when to use, trigger phrases>
allowed-tools:
  - <tool1>
  - <tool2>
---

# <Skill Title>

One-line description.

> **Key Reference**: [link](path)

## Quick Start (First-Time Users)

1. Verify setup
2. Common operations
3. Getting help

## When This Skill Activates

### Trigger 1
What happens, what to check

### Trigger 2
What happens, what to check
