# Configuring wpf-dev-pack Language This skill writes (or updates) a per-project preference file that tells the wpf-dev-pack plugin which language to respond in. A SessionStart hook (`hooks/LanguagePreferenceLoader.cs`) reads the file on every new conversation and emits a directive into the system context, so the preference takes effect automatically. ## When to use - The default language of a response does not match what the user wants (typical case: an English-speaking contributor in a project where wpf-dev-pack was originally tuned for Korean responses, or vice versa). - The user wants to switch language mid-project. ## When NOT to use - The user only wants a one-off language switch for the next response — just have them phrase the next message in the target language. Do not write a file for a one-shot. - The wpf-dev-pack plugin is not installed in the current project — the SessionStart hook will not run without the plugin. ## Workflow Copy this checklist and track progress: ``` Configure Progress: - [ ] Step 1: Detect current state of .claude/wpf-dev-pack.local.md - [ ] Step 2: Resolve target language (argument or AskUserQuestion) - [ ] Step 3: Write or update .claude/wpf-dev-pack.local.md - [ ] Step 4: Confirm and explain when the change takes effect ``` ### Step 1 — Detect current state Check whether `.claude/wpf-dev-pack.local.md` exists in the current project root. If it does, read its YAML frontmatter and find any existing `language:` value so the
