feat: Multilang Support Request

[serithemage]

"As a user from a non-English speaking region, I want the ability to use claude-task-master seamlessly in my native language (e.g., Korean, Japanese)."

Motivation

Currently, claude-task-master supports only English, limiting accessibility for users who are more comfortable interacting in their native languages. Adding multilingual support will enhance user experience and increase adoption among global users.

Proposed Solution

Introduce multilingual capabilities by allowing language settings in either the MCP or CLI configuration. When set, all prompts sent to Claude will explicitly request outputs in the chosen language.

• MCP or CLI will have a new language configuration option.
• Prompts automatically instruct Claude to generate documents in the specified language.

High-Level Workflow

1. Add a language configuration option to MCP/CLI.
2. Update prompt templates to include explicit instructions regarding language.
3. Validate language functionality and update documentation accordingly.

Key Elements

• Add language parameter in the configuration files and CLI.
• Update prompt templates to include explicit language instructions.
• Support commonly requested languages initially (e.g., Korean, Japanese).

Example Workflow

$ task-master configure --language ko
$ task-master create "개발자용 가이드 작성"
→ Claude generates a developer guide in Korean.

Implementation Considerations

• No external translation services needed; relies on Claude's built-in multilingual capabilities.
• Maintain backward compatibility by defaulting to English when the language is not specified.
• Minimal performance impact expected due to reliance on existing Claude multilingual processing.

Out of Scope (Future Considerations)

• Real-time automatic language detection and switching.
• Comprehensive localization of UI beyond document generation.

@eyaltoledano it looks like it can be generalized to adding a custom prompt from settings at the end of each current prompt… so I can add something about language and about format as well

It's definitely worth exploring this, and thanks for your suggestions @veged @serithemage

I don't love the idea of having to localize our prompts. that said, there's no reason we can't keep our english prompts, but to add a language flag that would optionally add a conditional wrapper to our prompts

Thus, if for example one of our prompts currently goes like

do abc and look at xyz

and the user selects --language="ko"

then the prompt being sent to the AI would look something like

answer to the below request in the KO language: 'do abc and look at xyz'

as far as documentation in other languages -- you're completely right that this should be done. the good news is i'm working to populate and improve our upcoming docs website. it's not ready yet (docs.task-master.dev). but the platform we're using (mintlify) has built in AI translation. so we can keep shipping english documentation, and we should be able to dynamically translate it as we go.

I know this is a pain point for you folks, and i'm not ignoring it. it's just something that i need to be able to prioritize and come up with a scalable solution

I am closing this ticket as it is a duplicate of the issue mentioned above.
