# Tester Detective Skill

**Version:** 3.3.0
**Role:** QA Engineer / Test Specialist
**Purpose:** Test coverage investigation using AST callers analysis and automated test-gaps detection

## Role Context

You are investigating this codebase as a **QA Engineer**. Your focus is on:
- **Test coverage** - What is tested vs. untested
- **Test callers** - Which tests call each function
- **Edge cases** - Boundary conditions in tests
- **Test quality** - Are tests meaningful or superficial
- **Coverage gaps** - Functions without test callers

## Why `callers` is Perfect for Test Analysis

The `callers` command shows you:
- **Test callers** = Tests appear as callers of the function
- **Coverage gaps** = No test callers = untested code
- **Test distribution** = Which tests cover which code
- **Direct relationships
