# Fullstack Dev Skills

> Jeffallan's specialist skills for full-stack work: language, framework, cloud, security and testing experts your agent loads on demand.

Fullstack Dev Skills is a community Claude Code plugin by Jeff Smolinski (Jeffallan): a pack of specialist skills for full-stack development, plus project workflow commands. Each skill is a focused expert, such as NestJS Expert, Debugging Wizard or Security Reviewer, that switches on from what you ask and loads its deeper reference files only when the task needs them. Bigger jobs chain several, for example Feature Forge, Architecture Designer, Fullstack Guardian, Test Master and DevOps Engineer for a new feature.

What its skills cover
- Languages: Python, TypeScript, JavaScript, Go, Rust, C++, Swift, Kotlin, C#, PHP, Java and SQL
- Backend frameworks: NestJS, Django, FastAPI, Spring Boot, Laravel, Rails and .NET Core
- Frontend and mobile: React, Next.js, Vue, Angular, React Native and Flutter
- Infrastructure and operations: cloud architecture, Kubernetes, Terraform, DevOps, SRE, monitoring and chaos engineering
- APIs and architecture: API design, GraphQL, microservices, WebSockets, CLI tools and MCP servers
- Quality and security: test strategy, Playwright, code review, debugging, documentation, secure coding and security review
- Data and ML: Postgres and database tuning, pandas, Spark, ML pipelines, RAG, fine-tuning and prompt engineering
- Platforms: Salesforce, Shopify, WordPress, game development, embedded systems and legacy modernization
- Thinking and specs: Feature Forge runs a requirements workshop and writes the spec, Spec Miner reverse-engineers specs from an undocumented codebase, and The Fool stress-tests a plan as devil's advocate, pre-mortem or red team

Workflow commands (Claude Code plugin only)
- /common-ground surfaces the assumptions Claude is making about your project so you can confirm or correct them.
- The /project commands take an epic from discovery through planning, ticket execution and retrospectives, working with Jira and Confluence. They need an Atlassian MCP server set up.

How to install it
- In Claude Code: /plugin marketplace add jeffallan/claude-skills, then /plugin install fullstack-dev-skills@fullstack-dev-skills, and restart when asked.
- Skills only, for other agents: npx skills add jeffallan/claude-skills. This leaves out the slash commands.

Good to know
- It's a community project by Jeffallan, MIT-licensed. It's built for Claude Code.
- Name your stack in the request ("in my NestJS API", "my React app") so the right skills switch on.
