Individual skill
test-deduplicator
Analyzes test suites to identify redundant and duplicate test cases using coverage analysis, semantic similarity, and execution results. Use this skill when you need to reduce test suite size, identify redundant tests, optimize test execution time, analyze test coverage overlap, find tests with identical behavior, or improve test suite maintainability. Triggers when users ask to deduplicate tests, find redundant test cases, reduce test suite size, identify duplicate tests, or optimize test coverage.

# Test Deduplicator
## Overview
This skill analyzes test suites to identify redundant or duplicate tests by examining code coverage, semantic similarity, and execution behavior. It groups equivalent tests, explains deduplication rationale, and recommends which tests can be safely removed while preserving overall test effectiveness.
## Workflow
### 1. Collect Test Coverage Data
First, gather coverage information for each test in the suite.
**For Python projects with pytest:**
```bash
