# GitHub Config Sync Skill Sync shared assets under `.github/` (ISSUE_TEMPLATE, PULL_REQUEST_TEMPLATE, workflows) from the shared-claude-code repository to the current project using file copies. File copies are used because GitHub does not recognize symlinks. ## Steps ### Step 1: Locate the Shared Repository 1. Search for symlinks under `.claude/rules/shared/` and `.claude/skills/` 2. Resolve the shared-claude-code repository path from the `readlink` result of found symlinks - Rule link example: `../../../shared-claude-code/rules/conventions.md` → extract `shared-claude-code` path - Skill link example: `../../shared-claude-code/skills/git-pr-create` → extract `shared-claude-code` path 3. If no symlinks are found → display error and exit: ```text エラー: shared-claude-codeへのシンボリックリンクが見つかりません。 最初のセットアップはREADMEの手順に従って手動で行ってください。 ``` 4. Verify that the `.github/` directory exists at the resolved path - If it does not exist → display error and exit ### Step 2: Detect Differences 1. Scan `.github/ISSUE_TEMPLATE/`, `.github/PULL_REQUEST_TEMPLATE.md`, and `.github/workflows/` on the shared side 2. Compare with the corresponding local files and determine each file's status: - **Identical**: contents match (determined by `diff -q`) - **Differs**: exists on both sides but contents differ - **New**: exists on the shared side but not locally - **Local only**: exists locally but not on the shared side (display warning only, do not delete) ### Step 3:
