When & Why to Use This Skill

This Claude skill provides a comprehensive collection of boilerplate templates and scaffolds designed to accelerate the development of Claude Code extensions. It simplifies the creation of custom expert agents, tool-based skills, slash commands, and automation hooks by providing standardized structures, naming conventions, and validation examples, ensuring high-quality and consistent agent infrastructure for developers.

Use Cases

  • Rapidly bootstrapping a specialized 'Expert Agent' persona (e.g., a React or Security expert) with predefined focus areas and quality checklists.
  • Creating new tool capabilities (Skills) with correctly formatted YAML frontmatter and command definitions for the Claude Code CLI.
  • Developing custom slash commands to automate repetitive developer workflows such as automated code reviews, documentation generation, or project scaffolding.
  • Implementing secure bash-based hook scripts to perform automated validation, linting, or testing during the Claude Code execution lifecycle.

Quick Start

Create an Agent

# Copy template
cp ~/.claude/skills/claude-code-templates/assets/agent-template.md \
   ~/.claude/agents/my-expert.md

# Edit: name, description, focus areas, references

Create a Skill

# Create skill directory
mkdir -p ~/.claude/skills/my-skill

# Copy template
cp ~/.claude/skills/claude-code-templates/assets/skill-template.md \
   ~/.claude/skills/my-skill/SKILL.md

# Edit: name, description, commands, examples

Create a Command

# Copy template
cp ~/.claude/skills/claude-code-templates/assets/command-template.md \
   ~/.claude/commands/my-command.md

# Edit: name, description, execution flow

Create a Hook Script

# Copy template
cp ~/.claude/skills/claude-code-templates/assets/hook-script.sh \
   .claude/hooks/my-hook.sh

# Make executable
chmod +x .claude/hooks/my-hook.sh

Template Locations

Templates are in ./assets/:

File Purpose
agent-template.md Expert agent boilerplate
skill-template.md Skill with YAML frontmatter
command-template.md Slash command scaffold
hook-script.sh Secure hook script template

Naming Conventions

Type Pattern Example
Agent {technology}-expert.md react-expert.md
Skill {tool-or-pattern}/SKILL.md git-workflow/SKILL.md
Command {action}.md review.md
Hook {event}-{action}.sh pre-write-validate.sh

Validation

# Validate YAML frontmatter
head -20 my-extension.md

# Check name matches filename
grep "^name:" my-extension.md

# Run project tests
just test
