Installation

Option 1: GitHub Marketplace (Recommended)

Inside Claude Code:

/plugin marketplace add yahyaalbashar/phinx-skills
/plugin install phinx-skills@phinx-marketplace

Option 2: Local Plugin (Quick Test)

git clone https://github.com/yahyaalbashar/phinx-skills.git
claude --plugin-dir ./phinx-skills

Option 3: Local Persistent Install

git clone https://github.com/yahyaalbashar/phinx-skills.git

# Inside Claude Code:
/plugin marketplace add /absolute/path/to/phinx-skills/.claude-plugin/marketplace.json
/plugin install phinx-skills@phinx-marketplace

Option 4: Direct Copy (No Plugin System)

git clone https://github.com/yahyaalbashar/phinx-skills.git
cp -r phinx-skills/skills/* ~/.claude/skills/

Management

# List installed plugins
/plugin list

# Disable temporarily
/plugin disable phinx-skills@phinx-marketplace

# Re-enable
/plugin enable phinx-skills@phinx-marketplace

# Update after repo changes
/plugin update

How It Works

Skills use progressive disclosure — only frontmatter (~50 tokens each) loads at startup. Full instructions load on-demand when Claude determines a skill is relevant. Total overhead: ~650 tokens for all 13 skills.

You say...	Skill triggered
"Build a dashboard component"	frontend-react
"Create the user API endpoint"	backend-api
"Set up Docker for this project"	devops-infra
"Design the schema for orders"	database-design
"Review this PR"	code-review
"Is this code secure?"	security-review
"How should we architect this?"	system-design
"This violates SRP"	clean-code-architecture

Explicit invocation: /phinx-skills:frontend-react, /phinx-skills:code-review, etc.

Agent Teams Usage

Create an agent team:
- Frontend agent: use frontend-react and testing-strategy skills
- Backend agent: use backend-api, database-design, and security-review skills
- DevOps agent: use devops-infra and performance-optimization skills
- Lead: use system-design, clean-code-architecture, product-thinking, and code-review skills
