Stop Using OpenCode

The provided documentation analyzes OpenCode's tool-calling implementation from an agent runtime developer's perspective. Rather than simply explaining current tool execution, it addresses the fundamental design problems a real coding-agent runtime must solve when moving beyond demo callbacks. The analysis references several primary code files, including tool.ts, registry.ts, and various session-related components such as processor.ts and llm.ts, to examine the internal architecture of the OpenCode system and its native runtime integration.
