This repository is an OpenCode plugin that provides interactive pseudo-terminal (PTY) management for AI coding agents. It allows agents to spawn, write to, read from, and kill multiple background terminal sessions, enabling long-running processes like dev servers, watch modes, and interactive programs. The plugin exposes five tools (pty_spawn, pty_write, pty_read, pty_list, pty_kill) and two slash commands for opening a web UI. The architecture is modular: a core PTYManager orchestrates session lifecycle, output buffering (via a RingBuffer), and exit notifications, while adapters decouple the plugin from OpenCode V1 and V2 APIs. A Bun-based web server serves a React frontend with real-time WebSocket streaming and a REST API for session management. The codebase demonstrates strong TypeScript patterns, clean abstractions, and comprehensive testing (unit, integration, and Playwright E2E).
