AI Advent Challenge Day 1

Kotlin/Native macOS CLI application that sends a prompt to OpenAI POST /v1/responses and prints the result.

Features

• Uses OPENAI_API_KEY from environment variables.
• Default mode (no flags): prints only assistant output_text.
• Verbose mode (-verbose): prints full response JSON.
• Uses kotlinx.serialization for JSON serialization/deserialization.
• Layered structure:
  • presentation (CLI parsing/output)
  • domain (repository contract + result model)
  • data (repository implementation + HTTP transport + API DTOs)

Prerequisites

• macOS
• JDK 17+
