Claude Code Plugin Marketplace

A curated collection of specialized Claude Code plugins designed to enhance your development workflow with intelligent agents, skills, and commands.

Official claude code marketplace: https://github.com/anthropics/claude-code

Overview

This marketplace provides three comprehensive plugin collections:

• devops-infrastructure: Infrastructure as Code (IaC), CI/CD pipeline specialists, and database optimization experts for DevOps workflows
• software-engineering: Code review, debugging, documentation, license compliance, payment integration, and HTML-first frontend development tools
• go-specialist: Advanced Go 1.25+ development with modern patterns, concurrency optimization, and production-ready tooling (linting, GitHub workflows, GitLab CI, GoReleaser)

Each plugin includes proactive agents that automatically assist with their specialized domains, plus skills and commands to streamline common development tasks.

Adding this Marketplace

/plugin marketplace add sgaunet/claude-plugins

For local development, you can also link a local folder:

git clone [email protected]:sgaunet/claude-plugins.git

Extras

The extras/ directory contains standalone utilities for Claude Code that are not plugins — they are helper scripts you install independently.

statusline

A lightweight bash statusline for Claude Code that displays the active model, context window usage with a color-coded progress bar, and total context size.

[Opus] ▓▓▓░░░░░░░ 30% | 200k ctx

Install: ./extras/statusline/configure-statusline.sh
Details: extras/statusline/install-statusline.md

no-leak

A PreToolUse hook that prevents Claude Code from reading or modifying sensitive files (.env, credentials, private keys, vault files). Unlike CLAUDE.md instructions, hooks are deterministic — the LLM cannot bypass them.

Install: ./extras/no-leak/configure-no-leak.sh
Details: extras/no-leak/install-no-leak.md

Creating New Agents

1. Choose appropriate plugin directory
2. Create plugins/<plugin>/agents/<name>.md
3. Add YAML frontmatter with name, description, model, color
4. Define proactive triggers (file patterns, keywords)
5. Document capabilities and deliverables
6. Validate: claude plugin validate .
