openrtk

OpenCode plugin for RTK (Rust Token Killer). Reduces LLM token consumption by 60-90% on common dev commands by transparently routing them through RTK's output compression.

A lightweight OpenCode plugin that intercepts shell commands and pipes them through RTK for automatic output compression. The model sees full output while RTK handles token reduction behind the scenes — no changes needed to prompts or workflow.

Prerequisites

Install RTK:

cargo install rtk

Installation

Add to your OpenCode config (opencode.json or .opencode/config.json):

{
  "plugin": ["openrtk"]
}

Or copy src/index.ts directly into .opencode/plugins/ for local use.

How it works

The plugin hooks into OpenCode's tool.execute.before event and rewrites shell commands to go through RTK before execution. This is fully transparent to the model.

git status       ->  rtk git status       (72% savings)
cargo test       ->  rtk cargo test       (80% savings)
docker ps        ->  rtk docker ps        (65% savings)
