go-test

# Go TDD Command

This command enforces test-driven development methodology for Go code using idiomatic Go testing patterns.

## What This Command Does

1. **Define Types/Interfaces**: Scaffold function signatures first
2. **Write Table-Driven Tests**: Create comprehensive test cases (RED)
3. **Run Tests**: Verify tests fail for the right reason
4. **Implement Code**: Write minimal code to pass (GREEN)
5. **Refactor**: Improve while keeping tests green
6. **Check Coverage**: Ensure 80%+ coverage

## When to Use

Use `/go-test` when:
- Implementing new Go functions
- Adding test coverage to existing code
- Fixing bugs (write failing test first)
- Building critical business logic
- Learning TDD workflow in Go

## TDD Cycle

```
RED     → Write failing table-driven test
GREEN   → Implement minimal code to pass
REFACTOR → Improve code, tests stay green
REPEAT  → Next test case
```

## Example Session

````
User: /go-test I need a function to validate email addresses

Agent:
# TDD Session: Email Validator

## Step 1: Define Interface

```go
// validator/email.go
package validator

// ValidateEmail checks if the given string is a valid email address.
