Claude Code Toolkit

September 16, 2026 · View on GitHub

Extend Claude Code with specialized workflows, automatic formatting, and better defaults.

Skills give Claude domain expertise—brainstorming methods, leading a project with worker agents, project wikis, book writing pipelines. Hooks automate repetitive tasks—format code after edits, summarize changes at session end. Templates configure how Claude works with you.

Works with both Claude Code (CLI) and Claude.ai (web/mobile/desktop).

Quick Start

# Clone the toolkit
git clone https://github.com/robertguss/claude-code-toolkit.git

# Use a skill in Claude Code
# Add to your project's CLAUDE.md:
echo "When brainstorming, read /path/to/claude-code-toolkit/skills/brainstorm/SKILL.md" >> CLAUDE.md

# Or package for Claude.ai
python build.py brainstorm
# Upload dist/brainstorm.skill to Claude.ai → Settings → Skills
