Claude Code Translate Output

A Claude Code mod that translates the agent's final answer of each turn into a language you choose and shows the translation in a side pane. Intermediate output (tool calls, progress messages, subagent reports) is not translated, and the original answer is left untouched: the translation is display-only and never enters the conversation context.

Install

In a Claude Code terminal session:

/plugin install translate-output --marketplace janzd/claude-translate-output

Answer y to add the marketplace, then pick a scope (user scope makes it available in every session, including the desktop app's Code tab).

Usage

/translate <language>   turn on, translating final answers into <language>
/translate              show the current language and reopen the pane
/translate off          turn off
/translate model <name> translate with <name> (haiku, sonnet, opus or a model id)
/translate model        show the model in use
/translate effort <level> set effort: low, medium, high, xhigh or max
/translate effort       show the effort in use

The language is free text and is passed to the model as written, so real languages (Japanese, Spanish, Esperanto), constructed ones (Quenya) and styles (pirate English, Shakespearean English) all work. The chosen language is remembered across sessions until you run /translate off.

After each turn the pane titled Translation (<language>) shows the translation; the status line reads Translating to <language>… while it runs.

How it works

• Hooks turn.complete and takes the turn's final visible answer, skipping subagent turns, interrupted turns and errors.
• Sends it to the translation model (haiku by default) via $.model.complete (a separate, history-free call on the session's own credentials), asking it to keep Markdown, code blocks, file paths, commands and identifiers unchanged.
• Draws the result in a pane through a ui.render hook.

To trade speed for quality (useful for less common languages), run /translate model sonnet. The model, like the language, is remembered across sessions. If the model name isn't recognized, the pane shows the error. /translate effort <level> sets how hard the model thinks (low by default); higher levels may help with literary styles or long technical answers, at the cost of speed.
