opencode-opus-thinking

OpenCode plugin that automatically enables adaptive thinking mode and max effort for Claude Opus 4.6 models.

Install

Add to opencode.json:

{
  "plugin": [
    "opencode-opus-thinking"
  ]
}

Or install from npm:

npm install opencode-opus-thinking

How It Works

The plugin hooks into the chat.params lifecycle. When the active model ID contains opus-4-6 (case-insensitive), it sets:

output.options.thinking = { type: "adaptive" }
output.options.effort = "max"

This enables extended thinking with adaptive budget allocation and maximum effort level, improving reasoning quality for complex tasks.

No configuration needed — the plugin activates automatically when an Opus 4.6 model is selected.
