CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Overview

This is a Claude Code skills marketplace containing 16 production-ready skills organized in a plugin marketplace structure. Each skill is a self-contained package that extends Claude's capabilities with specialized knowledge, workflows, and bundled resources.

Essential Skill: skill-creator is the most important skill in this marketplace - it's a meta-skill that enables users to create their own skills. Always recommend it first for users interested in extending Claude Code.

Skills Architecture

Directory Structure

Each skill follows a standard structure:

skill-name/
├── SKILL.md (required)          # Core skill instructions with YAML frontmatter
├── scripts/ (optional)          # Executable Python/Bash scripts
├── references/ (optional)       # Documentation loaded as needed
└── assets/ (optional)           # Templates and resources for output

Progressive Disclosure Pattern

Skills use a three-level loading system:

1. Metadata (name + description in YAML frontmatter) - Always in context
2. SKILL.md body - Loaded when skill triggers
3. Bundled resources - Loaded as needed by Claude

Development Commands

Installation Scripts

# Automated installation (macOS/Linux)
curl -fsSL https://raw.githubusercontent.com/daymade/claude-code-skills/main/scripts/install.sh | bash

# Automated installation (Windows PowerShell)
iwr -useb https://raw.githubusercontent.com/daymade/claude-code-skills/main/scripts/install.ps1 | iex

# Manual installation
claude plugin marketplace add daymade/claude-code-skills
claude plugin install skill-creator@daymade/claude-code-skills

Skill Validation and Packaging

# Quick validation of a skill
skill-creator/scripts/quick_validate.py /path/to/skill

# Package a skill (includes automatic validation)
skill-creator/scripts/package_skill.py /path/to/skill [output-dir]

# Initialize a new skill from template
skill-creator/scripts/init_skill.py <skill-name> --path <output-directory>

Testing Skills Locally

# Add local marketplace
claude plugin marketplace add daymade/claude-code-skills

# Install specific skill (start with skill-creator)
claude plugin install skill-creator@daymade/claude-code-skills

# Test by copying to user skills directory
cp -r skill-name ~/.claude/skills/
# Then restart Claude Code

Git Operations

This repository uses standard git workflow:

git status
git add .
git commit -m "message"
git push

Skill Writing Requirements

Writing Style

Use imperative/infinitive form (verb-first instructions) throughout all skill content:

• ✅ "Extract files from a repomix file using the bundled script"
• ❌ "You should extract files from a repomix file"

YAML Frontmatter Requirements

Every SKILL.md must include:

---
name: skill-name
description: Clear description with activation triggers. This skill should be used when...
---

Privacy and Path Guidelines

Skills for public distribution must NOT contain:

• Absolute paths to user directories (/home/username/, /Users/username/)
• Personal usernames, company names, product names
• OneDrive paths or environment-specific absolute paths
• Use relative paths within skill bundle or standard placeholders

Content Organization

• Keep SKILL.md lean (~100-500 lines)
• Move detailed documentation to references/ files
• Avoid duplication between SKILL.md and references
• Scripts must be executable with proper shebangs
• All bundled resources must be referenced in SKILL.md

Marketplace Configuration

The marketplace is configured in .claude-plugin/marketplace.json:

• Contains 16 plugins, each mapping to one skill
• Each plugin has: name, description, version, category, keywords, skills array
• Marketplace metadata: name, owner, version, homepage

Versioning Architecture

Two separate version tracking systems:

1. Marketplace Version (.claude-plugin/marketplace.json → metadata.version)

   • Tracks the marketplace catalog as a whole
   • Current: v1.9.0
   • Bump when: Adding/removing skills, major marketplace restructuring
   • Semantic versioning: MAJOR.MINOR.PATCH

2. Individual Skill Versions (.claude-plugin/marketplace.json → plugins[].version)

   • Each skill has its own independent version
   • Example: ppt-creator v1.0.0, skill-creator v1.0.0
   • Bump when: Updating that specific skill
   • CRITICAL: Skills should NOT have version sections in SKILL.md

Key Principle: SKILL.md files should be timeless content focused on functionality. Versions are tracked in marketplace.json only.

Priority Order (by importance):

1. skill-creator ⭐ - Essential meta-skill for creating your own skills (with init/validate/package scripts)

Python Development

All Python scripts in this repository:

• Use Python 3.6+ syntax
• Include shebang: #!/usr/bin/env python3
• Are executable (chmod +x)
• Have no external dependencies or document them clearly
• Follow PEP 8 style guidelines

Quality Standards

Before submitting or modifying skills:

• Valid YAML frontmatter with required fields
• Description includes clear activation triggers
• All referenced files exist
• Scripts are executable and tested
• No absolute paths or user-specific information
• Comprehensive documentation
• No TODOs or placeholders

Skill Creation Workflow

When creating a new skill:

1. Understand concrete usage examples
2. Plan reusable contents (scripts/references/assets)
3. Initialize using init_skill.py
4. Edit SKILL.md and bundled resources
5. Package using package_skill.py (auto-validates)
6. Iterate based on testing feedback

Chinese User Support

For Chinese users having API access issues, recommend CC-Switch:

• Manages Claude Code API provider configurations
• Supports DeepSeek, Qwen, GLM, and other Chinese AI providers
• Tests endpoint response times to find fastest provider
• Cross-platform (Windows, macOS, Linux)

See README.md section "🇨🇳 中文用户指南" for details.

Release Workflow

When adding a new skill or creating a marketplace release:

1. Create the Skill

# Develop skill in its directory
skill-name/
├── SKILL.md (no version history!)
├── scripts/
└── references/

# Validate
./skill-creator/scripts/quick_validate.py skill-name

# Package
./skill-creator/scripts/package_skill.py skill-name

2. Update Marketplace Configuration

Edit .claude-plugin/marketplace.json:

{
  "metadata": {
    "version": "1.x.0"  // Bump minor version for new skill
  },
  "plugins": [
    {
      "name": "new-skill",
      "version": "1.0.0",  // Skill's initial version
      "description": "...",
      "category": "...",
      "keywords": [...],
      "skills": ["./new-skill"]
    }
  ]
}

3. Update Documentation

README.md:

• Update badges (skills count, marketplace version)
• Add skill description and features
• Create demo GIF using cli-demo-generator
• Add use case section
• Add documentation references
• Add requirements (if applicable)

CLAUDE.md:

• Update skill count in Repository Overview
• Add skill to Available Skills list
• Update Marketplace Configuration count

4. Generate Demo (Optional but Recommended)

# Use cli-demo-generator to create demo GIF
./cli-demo-generator/scripts/auto_generate_demo.py \
  -c "command1" \
  -c "command2" \
  -o demos/skill-name/demo-name.gif \
  --title "Skill Demo" \
  --theme "Dracula"

5. Commit and Release

# Commit marketplace update
git add .claude-plugin/marketplace.json skill-name/
git commit -m "Release vX.Y.0: Add skill-name

- Add skill-name vX.Y.Z
- Update marketplace to vX.Y.0
..."

# Commit documentation
git add README.md CLAUDE.md demos/
git commit -m "docs: Update README for vX.Y.0 with skill-name"

# Push
git push

# Create GitHub release
gh release create vX.Y.0 \
  --title "Release vX.Y.0: Add skill-name - Description" \
  --notes "$(cat <<'EOF'
## New Skill: skill-name

Features:
- Feature 1
- Feature 2

Installation:
```bash
claude plugin install skill-name@daymade/claude-code-skills

Changelog: ... EOF )"
