**SCOPE: DINGO LANGUAGE TESTING ONLY** This agent is EXCLUSIVELY for testing the Dingo transpiler/language (Go code in /cmd/, /pkg/, /internal/). ❌ **DO NOT USE for**: - Astro landing page testing (use astro-reviewer instead) - Front-end/UI testing (use astro-reviewer instead) - React/JavaScript/TypeScript testing in langingpage/ (use astro-reviewer instead) ✅ **USE for**: - Dingo transpiler testing (cmd/dingo/, pkg/preprocessor/, etc.) - Golden test creation and validation - Parser testing - AST transformation testing - Language feature testing (Result, Option, pattern matching, etc.) - Integration testing for transpiler Use this agent when you need comprehensive test coverage for a new feature or implementation. Examples:\n\n<example>\nContext: The user has just implemented a new Result<T, E> type for the Dingo transpiler.\n\nuser: "I've just finished implementing the Result type. Can you help me test it?"\n\nassistant: "Let me use the golang-tester agent to create a comprehensive test suite for your Result type implementation."\n\n<task tool invocation with identifier="golang-tester" and task description about testing the Result type>\n</example>\n\n<example>\nContext: The user is working on the error propagation operator (?) and wants to validate it works correctly.\n\nuser: "Here's my implementation of the ? operator for error propagation. I want to make sure it handles all cases properly."\n\nassistant: "I'll launch the golang-tester agent to design test scenarios that validate your ? operator implementation across different edge cases and usage patterns."\n\n<task tool invocation with identifier="golang-tester" and task description about testing the ? operator>\n</example>\n\n<example>\nContext: The user has implemented pattern matching and mentions they want thorough testing.\n\nuser: "The pattern matching feature is done. I need to verify it works correctly."\n\nassistant: "Let me use the golang-tester agent to create a balanced test suite that will properly validate your pattern matching implementation without being overwhelming."\n\n<task tool invocation with identifier="golang-tester" and task description about testing pattern matching>\n</example>
