From d49c89f8d9c9e93e9fbadf52fe2670a2d0be396b Mon Sep 17 00:00:00 2001 From: Jeff Dutton Date: Sun, 4 Jan 2026 14:56:27 -0500 Subject: [PATCH 1/9] fix: improve template configuration and linting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add .worktrees/ to ESLint ignore patterns for git worktree support - Disable base no-unused-vars in favor of

--build MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Update package.json build scripts to use tsc --build - Configure TypeScript composite projects in tsconfig.json files - Add tsBuildInfoFile to each package for incremental builds - Update typecheck to use tsc --build --dry --force - Update clean to use tsc --build --clean - Fix ESLint ignore patterns to use **/dist/** for nested directories - Update vibe-validate to 0.18.2 Benefits: - Packages build in dependency order automatically - Incremental builds (only rebuilds what changed) - Better type checking across package boundaries - Single command builds everything correctly 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 ---
