Claude Code Settings/Skills for Vibe Coding

A curated collection of Claude Code settings, skills and sub-agents designed for enhanced development workflows. This setup includes specialized skills and subagents for feature development (spec-driven workflow), code analysis, GitHub integration, and knowledge management.

For OpenAI Codex settings, configurations and custom prompts, please refer feiskyer/codex-settings.

Setup

Using Claude Code Plugin

/plugin marketplace add feiskyer/claude-code-settings

# Install main plugin (skills and agents)
/plugin install claude-code-settings

# Alternatively, install individual skills
/plugin install codex-skill               # Codex automation
/plugin install autonomous-skill          # Long-running task automation
/plugin install nanobanana-skill          # Image generation
/plugin install kiro-skill                # Kiro workflow
/plugin install spec-kit-skill            # Spec-Kit workflow
/plugin install youtube-transcribe-skill  # YouTube transcript extraction

Note:

• ~/.claude/settings.json is not configured via Claude Code Plugin, you'd need to configure it manually.

Using npx skills

npx skills could be used to install skills only for your AI coding tools.

# List skills
npx -y skills add -l feiskyer/claude-code-settings

# Install all skills
npx -y skills add --all feiskyer/claude-code-settings

# Manually select a list of skills to install
npx -y skills add feiskyer/claude-code-settings

Manual Setup

# Backup original claude settings
mv ~/.claude ~/.claude.bak

# Clone the claude-code-settings
git clone https://github.com/feiskyer/claude-code-settings.git ~/.claude

# Install LiteLLM proxy
pip install -U 'litellm[proxy]'

# Start litellm proxy (which would listen on http://0.0.0.0:4000)
litellm -c ~/.claude/guidances/litellm_config.yaml

# For convenience, run litellm proxy in background with tmux
# tmux new-session -d -s copilot 'litellm -c guidances/litellm_config.yaml'

Once started, you'll see:

Open the link, log in and authenticate your GitHub Copilot account.

Note:

1. The default configuration is leveraging LiteLLM Proxy Server as LLM gateway to GitHub Copilot. You can also use copilot-api as the proxy as well (remember to change your port to 4141).

2. Make sure the following models are available in your account; if not, replace them with your own model names:

   • ANTHROPIC_DEFAULT_SONNET_MODEL: claude-sonnet-4.5

   • ANTHROPIC_DEFAULT_OPUS_MODEL: claude-opus-4

   • ANTHROPIC_DEFAULT_HAIKU_MODEL: gpt-5-mini

Skills

Skills are reusable capabilities that teach Claude how to complete specific tasks. They can be invoked via /skill-name [arguments] or triggered automatically based on context. Install only what you need:

/plugin marketplace add feiskyer/claude-code-settings
/plugin install codex-skill

/plugin marketplace add feiskyer/claude-code-settings
/plugin install autonomous-skill

You: "Please use autonomous skill to build a REST API for a todo app"
Claude: [Creates .autonomous/build-rest-api-todo/, initializes task list, starts execution]
