opencode-currency

An OpenCode plugin that converts USD amounts in AI responses into your local currency. It ships two halves:

• Server plugin — rewrites $100 / 100 USD in AI output to $100 (375.00 AED).
• TUI plugin — adds a currency.set palette command to pick your currency interactively. The choice is stored in .opencode/currency.json and shared with the server plugin.

Install

Add the package to opencode.json (server half):

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": [["opencode-currency", { "currency": "EUR" }]]
}

And to tui.json (TUI half):

{
  "plugin": ["opencode-currency"]
}

If you don't need the palette command, you can skip the tui.json entry.

Usage

Set the target currency with the currency option (ISO 4217 code, e.g. EUR, AED, JPY), or pick one in the TUI via the currency.set palette command. If no currency is configured, responses are left untouched.

Options (server)
