Create Agent TUI

Scaffolds a complete agent TUI in TypeScript targeting OpenRouter. The generated project uses @openrouter/agent for the inner loop (model calls, tool execution, stop conditions) and provides the outer shell: a customizable terminal interface, configuration, session management, tool definitions, and an entry point.

Architecture draws from three production agent systems:

• pi-mono/coding-agent — three-layer separation, JSONL sessions, pluggable tool operations
• Claude Code — tool metadata (read-only, destructive, approval), system prompt composition
• Codex CLI — layered config, approval flow with session caching, structured logging

Prerequisites

• Node.js 18+
• OPENROUTER_API_KEY from openrouter.ai/settings/keys
• For full SDK reference, see the openrouter-typescript-sdk skill
