Fullstack Dev Skills (Claude Skills)

Overview

Fullstack Dev Skills is a Claude Code plugin bundling 67 specialized skills across 12 categories: 12 language experts (Python, TypeScript, Go, Rust, Swift, Kotlin, C#, PHP, Java, SQL, C++, JavaScript), 7 backend framework experts (NestJS, Django, FastAPI, Spring Boot, Laravel, Rails, .NET Core), 7 frontend/mobile experts (React, Next.js, Vue, Angular, React Native, Flutter), plus infrastructure, DevOps, security, API/architecture, testing, data/ML, and platform specialists (Salesforce, Shopify, WordPress). It also ships 9 project-workflow slash commands (discovery through retrospectives) that integrate with Jira/Confluence via an Atlassian MCP server.

How it works

1. Context-aware activation. Skills load automatically based on the request's framework/language, not all at once, e.g. "Implement JWT auth in my NestJS API" activates NestJS Expert and loads its references/authentication.md.
2. Multi-skill workflows. Complex tasks chain skills in sequence, for example Feature Forge → Architecture Designer → Fullstack Guardian → Test Master → DevOps Engineer for new feature development.
3. /common-ground surfaces and validates Claude's hidden assumptions about the project before it starts working.
4. Workflow commands manage epics end-to-end (discovery, planning, execution, retrospectives) and sync with an Atlassian MCP server for Jira/Confluence.

Examples

"Implement user authentication in my NestJS API"
→ Activates: NestJS Expert + Secure Code Guardian

"My React app has a memory leak, help me debug it"
→ Activates: Debugging Wizard + React Expert

Installation

2. Install the plugin: /plugin install fullstack-dev-skills@jeffallan
3. Restart Claude Code when prompted.
4. Verify it worked by asking something framework-specific, e.g. "Help me implement JWT authentication in NestJS", and confirming Claude references the matching skill.

Alternative installs (skills only, no slash commands): claude plugin install https://github.com/jeffallan/claude-skills, npx skills add jeffallan/claude-skills, or copying ./skills/* into ~/.claude/skills/ for local development.
