Claude Code & OpenCode Skills

This repository contains reusable skills for Claude Code and OpenCode that extend the capabilities of your AI coding assistant with specialized workflows and domain knowledge.

What Are Skills?

Skills are extensions that add custom capabilities to Claude Code and OpenCode. They allow you to:

• Create custom slash commands (e.g., /slides)
• Provide domain-specific knowledge and conventions
• Automate workflows and tasks
• Share reusable functionality across projects

Skills follow the Agent Skills open standard and work across multiple AI tools.

Available Skills

Slides

Create professional HTML slide presentations from reference materials.

Usage:

/slides [input-files]

Features:

• Converts docs, PDFs, images, and markdown into clean HTML slides
• Dark modern aesthetic with CSS animations
• Keyboard navigation (←/→, Space, Enter)
• Animated charts and counters
• Fully self-contained HTML (no external dependencies)

Installation

For Claude Code

Skills can be installed at different scopes:

Option 1: Personal (Available in All Projects)

Install skills globally for your user account:

# Create the skills directory
mkdir -p ~/.claude/skills

# Clone or copy the skill
cp -r /path/to/cc-skills/slides ~/.claude/skills/

Option 2: Project-Specific

Install skills only for a specific project:

# Navigate to your project
cd /path/to/your/project

# Create the skills directory
mkdir -p .claude/skills

# Clone or copy the skill
cp -r /path/to/cc-skills/slides .claude/skills/

Option 3: Direct Clone

Clone this repository directly into your skills directory:

# For personal use
cd ~/.claude/skills
git clone https://github.com/raihan0824/cc-skills.git

# For project use
cd /path/to/your/project/.claude/skills
git clone https://github.com/raihan0824/cc-skills.git

For OpenCode

OpenCode searches multiple locations for skills:

Option 1: Global Installation

# Create the skills directory
mkdir -p ~/.config/opencode/skills

# Clone or copy the skill
cp -r /path/to/cc-skills/slides ~/.config/opencode/skills/

Option 2: Project-Specific

# Navigate to your project
cd /path/to/your/project

# Create the skills directory
mkdir -p .opencode/skills

# Clone or copy the skill
cp -r /path/to/cc-skills/slides .opencode/skills/

Option 3: Claude-Compatible Paths

OpenCode also supports Claude Code paths:

# Global (Claude-compatible)
mkdir -p ~/.claude/skills
cp -r /path/to/cc-skills/slides ~/.claude/skills/

# Project (Claude-compatible)
mkdir -p .claude/skills
cp -r /path/to/cc-skills/slides .claude/skills/

Using Skills

Manual Invocation

Call a skill directly using the slash command:

/slides presentation-notes.md company-logo.png

Automatic Invocation

Claude Code can automatically invoke skills based on your request:

Create a presentation about our Q4 results

Claude will recognize the task matches the slides skill and invoke it automatically.

With Arguments

Pass arguments to skills:

/slides --theme dark project-summary.md

Skill Priority

When the same skill exists in multiple locations, the following priority order applies:

1. Project skills (.claude/skills/ or .opencode/skills/)
2. Personal skills (~/.claude/skills/ or ~/.config/opencode/skills/)
3. Enterprise skills (managed by organization)

Project-level skills override personal skills with the same name.

Permission Control

Claude Code

Restrict skill access in /permissions:

# Deny all skills
Skill

# Allow specific skills
Skill(slides)

# Deny specific skills
Skill(deploy:*)

OpenCode

Control permissions in opencode.json:

{
  "permissions": {
    "skills": {
      "slides": "allow",
      "deploy": "deny",
      "internal-*": "ask"
    }
  }
}

Options:

• allow: Loads immediately
• deny: Hidden from agents
• ask: Prompts user for approval

Creating Your Own Skills

Basic Structure

Every skill requires a SKILL.md file:

my-skill/
├── SKILL.md           # Main instructions (required)
├── assets/            # Optional: templates, images
├── examples/          # Optional: example output
└── scripts/           # Optional: utility scripts

Minimal SKILL.md

---
name: my-skill
description: What this skill does and when to use it
---

# My Skill

Instructions for Claude to follow when this skill is invoked.

## Workflow

1. Step one
2. Step two
3. Step three

Required Frontmatter

• name: Lowercase, hyphens only, 1-64 characters
• description: When to use this skill, 1-1024 characters

Optional Frontmatter

---
name: my-skill
description: What this skill does
argument-hint: [file-path]           # Autocomplete hint
disable-model-invocation: true       # Only manual invocation
user-invocable: false                # Only Claude can invoke
allowed-tools: Read, Grep            # Restrict tool access
model: claude-opus                   # Custom model
context: fork                        # Run in isolated context
agent: Explore                       # Subagent type
---

Troubleshooting

Skill Not Found

Claude Code:

• Verify the skill is in ~/.claude/skills/<skill-name>/SKILL.md or .claude/skills/<skill-name>/SKILL.md
• Check that SKILL.md filename is uppercase
• Run /context to see loaded skills

OpenCode:

• Check ~/.config/opencode/skills/ or .opencode/skills/
• Verify you're in a git repository for project-local skills
• Ensure frontmatter has required name and description fields

Skill Not Triggering Automatically

• Make the description field more specific with clear keywords
• Try manual invocation with /skill-name
• Check if disable-model-invocation: true is set

Skill Triggers Too Often

• Make the description more specific
• Add disable-model-invocation: true to require manual invocation
