Laya Router Skill: local decision routing for Codex, Claude Code, OpenCode and Pi

# Laya Router Skill

[简体中文](README.zh-CN.md) · [繁體中文](README.zh-TW.md)

Universal, cross-platform local decision routing for AI coding agents, powered by Laya and Laya-MLX.

For ChatGPT Desktop (Codex), Codex CLI, Claude Code, OpenCode, Pi, and other Agent Skills compatible agents. Laya Router becomes available as a local decision capability. An agent invokes it only when its own skill or tool selection policy chooses to; use the CLI or configured MCP tool for an explicit call.

**Version: v0.2.0.** Real MLX, PyTorch and stdio MCP smoke tests passed on an Apple Silicon Mac. Explicit ChatGPT Desktop (Codex), Codex CLI, Claude Code and OpenCode calls were verified. Native Windows/Linux and Intel Mac inference remain unverified.

Laya Router is advisory only. Supported agents can invoke it when their skill or tool selection policy decides it is useful. Explicit invocation results are shown below; implicit invocation is agent-dependent and not guaranteed.
