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

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
