What problem does it solve? Claude occasionally drifts into English during sessions with Japanese-speaking users, forcing repeated manual corrections. This Skill pins the response language to Japanese with a single trigger, eliminating that friction. ## Core Features & Use Cases - Session-wide language lock: Once invoked, all user-facing prose is written in Japanese until /run-english is called or the user explicitly requests English. - Selective translation: Code, identifiers, file paths, commands, and established technical terms (gRPC, Unix Domain Socket, BepInEx) remain in their original form for readability. - Scoped to conversation only: Artifact language conventions (commit messages, docs, code comments) still follow project rules; only the chat response language is overridden. - Use Case: A Japanese-speaking developer working on the ResoniteIO project notices Claude replying in English mid-session and invokes /japanese once to keep all subsequent answers in Japanese. ## Quick Start Invoke the /japanese skill or say "日本語で返して" to lock all subsequent responses to Japanese.
