SmartWatermelon Marketplace

A curated collection of quality-focused plugins for Claude Code, emphasizing critical code review, testing tools, and development workflows.

Philosophy

This marketplace focuses on plugins that:

• Challenge assumptions rather than validate them
• Identify failure modes before they reach production
• Prioritize long-term maintainability over short-term convenience
• Provide actionable feedback rather than vague suggestions

Installation

Add this marketplace to your Claude Code installation:

claude plugin marketplace add github:smartwatermelon/smartwatermelon-marketplace

After adding the marketplace, you can install individual plugins:

# Install specific plugin
claude plugin install code-critic@smartwatermelon-marketplace

# Or install all plugins
claude plugin install --all smartwatermelon-marketplace

Available Plugins

Code Critic

Status: Stable v1.3.0 Category: Quality / Code Review

Skeptical code review agent that assumes code is wrong until proven otherwise. Unlike validation-focused reviewers, Code Critic challenges architectural decisions, identifies failure modes, and prioritizes long-term maintainability.

Features:

• Reviews code hierarchy: Purpose → Architecture → Failure Modes → Maintenance → Implementation
• Challenges assumptions and asks "why" before "how"
• Identifies race conditions, error handling gaps, and scalability issues
• Integrates with git hooks for automated review

When to use:

• Security-critical code (auth, payments, data handling)
• Architectural changes
• Complex business logic
• High-risk refactoring

Documentation: plugins/code-critic/README.md

Install:

claude plugin install code-critic@smartwatermelon-marketplace

Coming Soon

More plugins are in development:

• test-driven-discipline: TDD workflow enforcement and test quality analysis
• performance-guardian: Performance regression detection and optimization suggestions
• api-contract-validator: API contract testing and breaking change detection
• documentation-critic: Documentation completeness and clarity analysis
